How to Release and Renew an IP Address. If you’re working in IT, there are a few things that you need to know no matter what. They are basically essential skills for any IT person. One of those skills is knowing how to renew and release IP addresses. You’ll need to do this a lot during your IT career and it’s really useful for getting your computer reconnected to the Internet or to the local LAN network. Renewing an IP address can also help fix an IP address conflict. In order to renew an IP address, go to Start, then Run and type in CMD to open a new command prompt window. Now type in the following command: ipconfig /renew. Whichever network adapters are currently connected on the computer will go out and have their addresses renewed with the DHCP server. If you are unable to renew an IP address, you can read my previous post on how to fix the Cannot renew IP address error. To release an IP address, type in the following command: ipconfig /release. This command will release the IP address for all connected adapters. Note that you can also refresh all DHCP leases and re- register DNS names using the registerdns command. If you’re having other issues, like being able to connect to your wireless router, but not to the Internet, read my previous post. ![]() ![]() ![]() I only remember one practical writing lesson from my three years as an English major: Whenever you can, put the best bits at the end of the sentence.![]() If you find that your internet connection, in Windows 10, Windows 8, Windows 7 or Windows Vista, has suddenly stopped working or that you are facing certain Network.

Troubleshoot Cannot Connect to Internet in Windows. Having problems connecting to the Internet on your Windows machine? Windows does a pretty good job of determining if there is a problem in Windows that is preventing the computer from accessing the Internet and then fixing it, however, not all Internet problems are related to the computer. Before your computer can access the Internet, it needs to pass through the cable modem or router provided by your ISP. A misconfigured or malfunctioning router will prevent all your devices from connecting to the Internet. In this post, I’m going to talk about all the different ways you can try to fix Internet connection problems. I’ve broken into down into three categories: solutions related to the OS, solutions related to the computer and solutions related to network/router/ISP. Before you begin, try to determine what category your problem falls into. For example, if you are not able to connect using Internet Explorer, but Firefox or Chrome work, then that would be an OS related issue. If nothing on your computer connects to the Internet, but another computer on the same network can connect, that would be a computer related issue. Finally, if none of your devices can connect, it’s definitely a router/modem or ISP issue. OS Related Problems. Toggle Automatically Detect Settings option. If you are having problems with only IE, check the Automatically Detect Settings option in LAN settings. You can get there by going to Tools (or clicking on the gear icon), Internet Options, Connections, LAN Settings. Make sure that Use a proxy server for your LAN is unchecked and that Automatically detect settings is checked. Disable Enhance Protected Mode. Enhance Protected Mode is a feature in IE 1. IE 1. 1 that makes your browsing more secure by enabling additional security features. It is usually not enabled by default unless in a corporate environment. It can prevent certain add- ons from working if they are not compatible. If you are having trouble connecting to the Internet using IE 1. Internet Options, click on the Advanced tab and make sure Enable Enhanced Protected Mode is unchecked. Computer Related Problems. If nothing on your computer can connect to the Internet, but other computers work fine, then you know there is something wrong with that one particular computer. Let’s go through some possible solutions. Check All Hardware. The first thing to do is to check the obvious stuff. If you are using a hard- wired connection, make sure the cable is plugged in fully into your router and computer. Also, try a different cable in case there is a problem with the cable. Secondly, if you are connecting via Wi. Fi, make sure that it is turned on if you are using a laptop. Some laptops have physical switches that let you turn off the wireless functionality. On some laptops, you have to press a key combination like Fn + F5 to enable/disable the wireless card. Turn Off Firewall/Anti- Virus Programs. This is another really common cause for Internet connection problems. Lots of people buy these Internet protection suites that include anti- virus, anti- malware, firewall, web security, and other software. Sometimes the software goes overboard and it ends up messing up your connection to the Internet. You can usually try turning off just the firewall instead of the entire software suite. However, I would suggest disabling everything at least once to make sure it’s not the security software causing the Internet problem. Check TCP/IP Settings. Next, we want to make sure that the network card is getting an IP address from a DHCP server and does not have a static IP address assigned. To do this, click on Start and type in ncpa. Enter. This will bring up the list of network adapters in Control Panel. Right- click on the one that is currently connected and choose Properties. Note that if you have multiple adapters connected like Ethernet and Wi- Fi, you should disconnect one as having both connected at the same time shouldn’t necessarily cause any problems, but sometimes it might. Click on Internet Protocol Version 4 (TCP/IPv. Properties. In the next dialog, make sure that the Obtain an IP address automatically and Obtain DNS server address automatically radio buttons are selected. Enable/Disable/Uninstall Network Card. The next step you can take is to try disabling the network card and then enabling it again. Sometimes that will help the computer get an IP address if it didn’t already have one. You can do this by clicking on start and typing ncpa. Right- click on the network card and choose Disable. Once disabled, just right- click again and choose Enable. If this doesn’t work, you can try uninstalling your network card completely. When you do this, you have to restart your computer and Windows will reinstall the network card automatically. Click on Start, type in Device Manager and then expand Network adapters. Right- click on the network card you’re using for network and Internet access and then click on Uninstall. Update Drivers. If you are running a newer version of Windows on an older machine, then you might have to upgrade your drivers. For example, if you upgraded Windows 7 to Windows 1. Windows 1. 0 drivers for your network card. Check out my previous post explaining how drivers work in Windows and how you can update your drivers automatically. For your network card, it might be easier to just visit the website for your computer manufacturer and download the latest driver for your network card from there. As you can see from the screenshot above, my Dell computer is not tested for Windows 1. That means if I upgrade, some hardware may not work with that operating system. Be sure to check before you upgrade. Even if you upgraded your OS and the latest driver isn’t available for your version of Windows, it’s still worth downloading the latest version of the driver and seeing if it fixes the problem. Try Network Troubleshooter. If nothing has worked as of yet, try to use the network troubleshooter in Windows. You can do this by going to the Network and Sharing Center in Control Panel. At the bottom you will see Troubleshoot problems. Now click on Internet Connections and run through the wizard. Windows will try to detect the reason for the connection problem and fix it. It has worked for me on several occasions, so it’s worth a shot. Reset TCP/IPIf you’re still without Internet, you might have to reset the TCP/IP stack. You could run the commands yourself via command prompt, but Microsoft has a small utility you can download that does it for you. Check out this KB article from Microsoft on how to reset the TCP/IP stack and click the download button for your version of Windows. If you are running Windows 1. Windows 8. 1 and it should work. Router/ISP Related Problems. If none of the devices on your network can connect to the Internet, it’s probably a modem/router or ISP issue. Here is what you can do. Restart Router/Modem. The simplest solution and the one that works the most often is restarting your modem or router or both. If you have a combined modem/router from your ISP, just restart that device. If you have a separate modem from your ISP and your own router, restart both of them. In the latter case, you should actually turn both of them off and then turn the ISP modem back on first. Wait until all the lights are green or active and then turn on your wireless router. If you have any switches, etc. Just about all routers have a power button. If not, just unplug the power cable from the router, wait 3. Reset Router. If restarting your router doesn’t work, you may have to reset your router. This is a last resort step because it will erase all the wireless settings for your router. If you want your devices to connect back without having to re- enter the Wi. Fi password, you’ll have to setup the wireless settings exactly as they were before you reset the router. The reset button is usually a tiny hole in the back on your router that you have to press for a certain amount of time ranging from 1. If you just have one device not connecting to the Internet, it could be a problem with the wireless security settings. If you have a device that does not support stricter encryption standards like WPA2, you might have to lower the security settings so that the device can connect. Contact ISPSometimes, your ISP may be having issues in your area and it could be causing Internet connection issues. Other times, your ISP may block your Internet connection if it detects too much spam originating from your IP address or if you get caught downloading a lot of illegal stuff. If one of your computers has become infected with a nasty virus or malware and you don’t know about it, it could be using your computer and your Internet connection for bot- net attacks, etc. Contact your ISP and see if they have any complaints on file with you or if there is some outage in your area. Your ISP will also be able to connect to your router directly and run tests to make sure everything is configured properly. Hopefully, one of the above solutions will fix your problem. If not, post a comment and I’ll try to help. Tech - How To Information. Undelete, upgrade HDD, disk cloning, bootable USB flash. Unique handy tools with USB flash, no install. Total.

I upgraded from Windows Vista to 7 on my laptop a few months ago and it retained the HP Recovery partition (Drive D: ), which I did not want ($3. I did a cleaninstall, so there is no HP software on my drive (thank goodness). Is it okay if I wipe it and use the space? Under properties it shows that I am using 1. G of 1. 1. 9. G, but there are no files in this partition. Even if I unhide my files it has nothing. I have a system restore disk and I manually backup (image and data) on a regular basis. Regular for me is about once every 1- 2 weeks depending on what programs I have installed or uninstalled. I could really use the space on this laptop since it only has a 1. G HDD. Furthermore, I am planning on adding another HDD (probably a better one, but same size) in the future and will restore an image to the new drive and I want to be able to format the old drive completely for maximum storage capacity. PS. I do not want SSD (imo tech still new to be considered as reliable compared to HDD). Should I go with 7. Im not sure of the brand of drive my laptop has now, but I do know it is 5. SATA I. I was thinking of Saegate Momentus 7. MB cache or WD Scorpio Black 1. BEKT w 1. 6MB cache. Both priced about $5. The upgrade to 7. I am concerned about heat. I know HP dv. 90. I do leave it on most of the day though). I use a cooling stand and I try to keep my vents clean. My PC does get hot on occation, but I rarely use it as a true portable device anymore since the battery is just about dead, so it pretty much stays on the stand 9.

OS Sierra Problems. For most users, installing mac. OS Sierra has gone without a hitch and they’re left with a trouble- free Mac that works great with the latest mac. OS system software release. But, not everything goes smoothly for everyone, and sometimes updating to mac. ![]() ![]() ![]() OS Sierra can lead to a variety of problems. We’re compiling a list of common problems in this troubleshooting guide to remedy issues with the mac. OS Sierra download, installation, update, and post- install process. Unfortunately for me (but fortunately for you readers), I personally have had the joy of encountering many of these problems during and after updating one particular Mac. Book Pro to Mac OS Sierra 1. I have very recent extensive firsthand experience with troubleshooting much of what is covered here. To be perfectly clear this is meant to be a compilation for potential issues experienced with the mac. A quick search in iTunes will yield a fair number of apps that aim to help you print to your printer, but also keep an eye out for an app from the folks who make your.![]() OS Sierra update process. Most of this will not be encountered by the average user, and is in no way suggestive of what to expect during the Sierra update or installation process. The vast majority of Macs update to mac. OS Sierra without any adverse incident. OS Sierra Download Stops with “An error has occurred” or “failed to download”Sometimes when users attempt to download mac. OS Sierra from the Mac App Store they will confront a “An error has occurred” red message and the download stops. The solution to this is fairly straight forward: Delete any existing Sierra installers, whether they are half- downloaded or not, reboot the Mac, and try again. I ran into variants of the download trouble several times. What finally resolved it was to delete the half- cooked “Install mac. OS Sierra” file from Launchpad (which had a big question mark on it), then rebooting. Unable to Download mac. OS Sierra, shows as “Downloaded”If the Mac App Stores shows that “mac. OS Sierra” has “Downloaded” and the button is not possible to click again, you likely had one of the beta or GM builds and you will need to remove any existing “Install mac. OS Sierra” application installers from the Mac, or any connected drives. That last part is critical, because it appears the Mac App Store has no trouble locating a named “Install mac. OS Sierra. app” located on an external volume. Yes this includes even the GM builds which share the same name as the installer app, and prevents the installer from downloading again. Of course the other reason mac. OS Sierra will show as “Downloaded” under the Mac App Store Purchases tab is if you are actively running mac. OS Sierra, in which case you will not be able to re- download the installer easily. Error “This copy of the Install mac. OS Sierra. app application is damaged, and can’t be used to install mac. OS.”Something happened during the installer download where it was either interrupted or became corrupted. Typically this means the internet connection was disrupted, or the file itself somehow was interfered with during the transfer. You will need to delete the “Install mac. OS Sierra. app” and download it again from the Mac App Store. If this applies to you, you will likely need to trash the wi- fi prefs and then create a new network location to resolve wireless networking problems like this. We have a detailed guide to fix wi- fi problems with mac. OS Sierra here. The good news is that wi- fi trouble is usually really easy to fix and the above article details specific steps to take which remedy the vast majority of wireless networking difficulties. This gives the appearance that the Mac is off, but it’s actually on and the screen is just stuck dark, with the Mac doing who knows what. This can happen right after the initial installation, but also during a standard Mac system restart after having updated to Sierra. I personally experienced this in the latter scenario during a regular reboot, and as you can imagine it’s fairly annoying to discover the Mac won’t boot up normally. Fortunately with prior experience handling a similar issue, I was able to resolve it with the following steps in this order: Disconnect all USB cables and USB devices from the Mac, aside from a mouse or keyboard if applicable. Shutdown the Mac. Reset SMCReset NVRAM/PRAMBoot as usual. It may not be necessary to reset both PRAM/NVRAM and SMC, but since you’re already doing one you might as well do the other. You’ll lose a few basic power settings by doing so, but it’s not a big deal, and it resolved the stuck on black screen issue for me. Some Mac. OS Sierra users have reported similar issues with their Mac getting stuck on a black screen when waking from sleep. Often the same SMC and NVRAM reset procedure remedies those difficulties. Unable to Shut Down mac. OS Sierra, Unable to Reboot mac. OS Sierra. There appears to be a bug for some users that prevents the Mac from using the . Selecting the menu items results in no activity and no action, the Mac does not reboot and it does not shut down. Sometimes a third party app can be holding up the shut down and restart service, however. If you suspect this is the case, quit out of all open apps before attempting to shut down or restart the Mac. You can also try disconnecting all external devices, which has been reported to help some users shut down Mac. OS Sierra. The other option is to forcibly shut down and reboot the Mac by holding down the Power key. The forced shut down and forced reboot procedure is a measure of last resort and should not be used as a means of initiating any normal restart or shut down process. Some users have resolved the hanging on shutdown issue by rebooting into Safe Mode. Booting a Mac into safe mode is easy, just hold down the SHIFT key on system boot until you see the bootup progress bar, then let go. Safe Mode will clear out some caches and disable some functionality, but it can often be a helpful troubleshooting measure. Constant i. Cloud Error and i. Cloud Authentication Pop- Up Messages. Many components of mac. OS Sierra are dependent on i. Cloud, and during the initial setup process you’ll be asked to enable various i. Cloud features including Storage Optimization and i. Cloud Documents and Desktop. Whether you want to use all of those features or not is up to you, but an odd side effect encountered by some is constant i. Cloud error messages and pop- ups to authenticate. Two persistent popups that I was running into were “This Mac can’t connect to i. Cloud because of a problem with (email address)” and “Error connecting to i. Cloud”. I was able to fix the i. Cloud errors and make them go away by doing the following: Go tot he . Another separate problem with Safari in mac. OS Sierra seems to be sporadic difficulties loading webpages and contacting servers, leading to an inability to load any webpage at all. A quick side note: the “can’t find server” message can be due to wi- fi dropping, so if the connection difficulties are not limited to Safari you may want to use the wi- fi fix mentioned above. Another odd variation of this is Safari failing to load webpages repeatedly, but after persistent refreshing, Safari may be able to successfully load a webpage but minus CSS (CSS being what styles the majority of webpages). Additionally, another oddball Safari problem is when the browser URL bar and buttons vanishes entirely and no webpage loads at all. Sometimes quitting and relaunching Safari will remedy these issues, but usually you will need to reboot the Mac to get Safari working again for a while. Another unusual error message you may encounter with Safari problems in mac. OS Sierra is an inability to load a webpage, where the tab or window renames itself to “Resources” and you get a blank page loading stating: “Your copy of Safari is missing important software resources. Please reinstall Safari.”Since you can’t really “reinstall Safari” in mac. OS Sierra, the error recommendation is not particularly helpful, and instead you’ll likely want to reinstall all of mac. OS Sierra or revert to the prior Mac OS version from a backup. Spotlight Doesn’t Work with mac. OS Sierra. Some users, myself included, have noticed that Spotlight just stops working entirely at random in mac. OS Sierra 1. 0. 1. Sometimes Spotlight will sort of half- work, but the results returned are completely inaccurate and don’t match the search term. This is not because of indexing, mdworker, or mds, however. You can kill the Spotlight process, it will spin back up, but the Spotlight search ability does not regain functionality. The only way to return Spotlight functionality in this situation is to reboot the Mac. Inconvenient, a bit Windows- esque, but it works. You can also try to rebuild the Spotlight index directly, but you’ll still likely need to reboot the Mac to have Spotlight start working again as expected. Mouse Not Working, Mouse Functionality is Erratic with mac. OS Sierra. Some users have discovered their mouse is not working at all, or the mouse may be working erratically after updating to mac. OS Sierra. For example, the scroll wheel functionality may become unresponsive or not work as intended. Some of these mouse issues have been narrowed down to Logitech and Razor brands, perhaps pertaining to drivers or software, but some of the erratic mouse behavior can occur with generic USB mice as well. One possible fix for these issues is to connect the USB mouse directly into the Mac, rather than going through a USB hub. Mac is Hot, Mac Fans Running at Full Speed After mac. OS Sierra Installation. If the computers fans are running after updating to Mac. OS Sierra and the Mac feels hot to the touch, it’s very likely to because the Mac is indexing. This is not indicative of a problem in and of itself, and it’s perfectly normal for the Mac to require reindexing the entire hard drive for features like Spotlight and Siri to work. Additionally, the new Photos app for Mac index the Photo library to identify places, features, faces and people, and other landmarks, which can also take a while. MEMBERSHIP .
