I have a strange problem with Windows 7. It all started couple of days ago. On my Dell XPS laptop I have two network interfaces, one LAN one WLAN. When I power up my computer I have a small yellow triangle on network icon that says no internet access for my LAN connection. I have an IP address from my DHCP. Ping does not work and tracert outputs this:
Tracing route to superuser.com [22.214.171.124] over a maximum of 30 hops: 1 XPS [192.168.1.124] reports: Destination host unreachable. Trace complete.
The first time this happened I googled a bit found this tip:
netsh int ip reset
I ran it, rebooted, and it worked. The first time. Next day it didnt work. I ran it a few times, fiddled a bit with networks and it worked. Next day, nothing worked and thats why I'm writing here – cause I'm out of ideas.
And another thing, if I disconnect LAN cable and power on WLAN everything works fine. I wonder for how long.
What should I do? It seems the only solution is to reinstall Windows 7 from scratch but if I'll have to do that every 30 days (yes, I installed it 30 days ago) – screw Windows 7, I'm going back to XP. I need my network to work!
