Hey,
 
I was away from my apartment for a week and after returning today I noticed that my internet wasn't working. On my PC I use a direct ethernet cable, but I also have a WLAN setup which is not working either. The router keeps saying that there was a problem with the ISP's DHCP whereas the main PC says Unidentified Network - No network access with the yellow triangle over the network icon in the taskbar.
 
ipconfig /renew gets stuck and wont perform at all, with an error message:
An error occurred while renewing interface Ethernet : unable to contact your DHCP server. Request has timed out.
 
 
Any help is greatly appreciated, here's my ipconfig /all

My main PC is Windows 10 yes. However this happens on all my other devices too since the router isn't able to connect either.

 

As for the thread you linked, I'm unable to perform the ipconfig /release ipconfig /renew as mentioned in the original post. As I'm using a hotspot to connect right now I'm unable to download the linked update for now. However there were no Windows updates installed while I was away, and it was working properly before so I don't think that's the issue.

If you think it is related to the router, what model router do you have and how is it configured(DHCP, PPPoe, AP, etc)? Also, what model modem or gateway do you have it connected to?

 

Have you tried connecting direct to the modem and trying the suggestions in the thread? The reason a DHCP renew isn't working is because your computer can't find what the DHCP server is. It should usually be the IP of your router(ie 192.168.1.1). Notice in your IP config it is blank. Hopefully by bypassing the router and trying a winsock reset you can get online. The 169 issue is happening all over the world and as of now patch KB3206632 is suggested if a winsock reset fixes the issue. See this other thread for more info.

The router is Asus RT-N12E and should be configured to DHCP. I'm not aware of any modems, as there is a direct ethernet socket in the wall (Maybe there's one installed to the wall, or a general one for the whole apartment complex since it's a student apartment with internet provided by the university). So I reckon this whole time I have been "directly connected to the modem"(?)

 

I attempted connecting directly to the router, and was able to perform ipconfig /release, ipconfig /renew, and netsh winsock reset, but none helped.

"with internet provided by the university"

 

I would contact the University's IT department then. Making some assumptions about your username, but maybe try campushelp@cija.ca .

"So I reckon this whole time I have been "directly connected to the modem"(?)"

 

Probably not. You are connecting to the University's network. I have no idea how their network works but I doubt it uses modems. Many University use MAC address whitelists that only allow devices of certain MAC address to get a IP from DHCP. Have you tried connecting your PC direct to the wall and seeing if you can get online then?

I am just curious; who ended up being the ISP? Also, what was the issue? I ask just encase someone else has a similar problem.
