Are you having trouble connecting to the internet ? Do you have Windows 10 DHPC issues ?
Has the internet suddenly stopped working? loss of internet connection. No valid IP address.
Do you suddenly get kicked offline? Can you only connect to your Local Network, not the internet ?
Over the last few days Microsoft has started to get reports of user loss of connectivity in Win10 (wired and wireless). The basic symptom is getting an IP address that is default 169.x.x.x and no internet connection.
There are numerous threads on various forums as well as all the social media channels about this. Some examples are:
The basic advice from Microsoft is to reboot the computer fully which temporarily fixes the problem, while further investigations are carried out and a full fix are found and issued. One suggestion direct from Microsoft is to install the Windows 10 cumulative update kb3201845 issued on 9 December 2016. This temporarily fixes it by forcing a reboot. You need to do a full restart of the computer. To restart, select the Start button from the taskbar, click the Power button and choose Restart (not Shut down). as described in https://answers.microsoft.com/en-us/windows/forum/windows_10-networking/problems-connecting-to-the-internet/f121306e-fab5-411d-833f-e4490ecb8b5c?tm=1481238027434
Other suggestions that were originally posted ( that worked for a few people but the problem came back ) was to open an Elevated Command Prompt, run IPCONFIG /release and then IPCONFIG /renew
Now this morning 10 December 2016 we are seeing the twittersphere & bloggersphere running wild and have got the wrong end of the stick, blaming kb3201845 http://www.ghacks.net/2016/12/10/windows-10-update-kb3201845/ for causing the problem. If you install Any windows update and do not reboot, you will always get some system instabilities. Microsoft’s latest advice is to install KB3201845 to temporarily fix the problem.
Some people have been complaining about this for almost 1 month so it definitely is not related to KB3201845 https://www.reddit.com/r/sysadmin/comments/5d8gks/does_anyone_else_have_problems_with_windows_10/?st=iwf4kros&sh=92b4673b
Woody over on Infoworld has his usual thoughts on the topic. He thinks it is mainly W10 users that have installed the Anniversary Update that are affected, but reports are around that it also is affecting W8.1 and some W7 users.
Although the vast majority of Wi-Fi problem reports come from Win10 version 1607 systems, there are other reports of the same problem on Win 7 and 8.1 PCs using domain-connected and not-connected systems with a wide array of ISPs, routers, and network cards.
Speculation at this point says the disconnect results when a machine performs a fast startup, setting the machine’s IP address to 169.x.x.x. It’s an old problem, but somehow it’s come back in spades in the past two days. I have no idea what triggered the sudden outbreak, as there were no Win10 1607 patches issued on Dec. 6, 7 or 8.
A fix that might work for many users is to turn off fast start in your Windows 8 or Windows 10 pc. This has the slight downside of taking longer to boot each day. There is no fast start on W7, so this tweak won’t do anything for any W7 users affected.
Another alternative that also might work is to disable “Allow windows to turn off this device to save power ” on your network card driver settings. You will still need to restart windows but hopefully this will prevent a future occurrence of it. There are two ways to do this.
- Right click the internet connection icon in task bar/ open network and sharing centre / change adaptor settings / right click your currently in use adaptor ( network card or wifi card) / properties /configure / power management. Remove the check mark from “Allow windows to turn off this device to save power ” press ok and exit out from all screens
- Open device manager ( windows 10 ) Right-click or press and hold on the Start button, then select Device Manager from the context menu. or this method which works for all currently supported Windows versions https://www.drivereasy.com/knowledge/a-common-and-easy-way-to-access-device-manager-in-windows/ then right click your currently in use adaptor ( network card or wifi card) / properties /configure / power management. Remove the check mark from “Allow windows to turn off this device to save power ” press ok and exit out from all screens
