Lan not working on my modem but works on friend's

[Dusan_11]

Recently i have checked my laptop for viruses using rouge killer, 15 minutes after cleaning some malware, i couldnt connect to my lan connection anymore, i have checked on my friends router and it works fine, also my wifi is ok.
I have tried many cables, restarted router couple times but nothing happens.
Just yellow triangle apperas and nothing else, local area is not disabled, ipv4 is enbled, ipv6 is enabled( tried to disable).
Device manger is not reporting any problem.
Used realse/ renew commands in cmd.
Does anyone knows how to resolve it?

Check Internet Options(control panel) for Proxy Settings. Set to do not use any proxy settings.
Sometimes virus's will set you up to a proxy server, so all your internet traffic routes through their server so they can control what sites you visit and record all traffic.

reinstall LAN driver, maybe it was infected and damaged during virus cleanup.

have you tested to see if your router(and I'm assuming a router or router/modem, not just a modem) is serving DHCP(assigning addresses). Otherwise assign a static IP and it should work if dhcp is not working.

if you are getting a 169.x.x.x address than you aren't receiving an address via DHCP and windows is assuming a pretend IP.
