I am facing a weird problem recently. When I reboot my computer with the LAN cable plugged in, it's connected and everything works fine. But when I remove the cable and plug it in again, it detects LAN but shows no internet access (And in 1 or 2 cases, it didn't detect LAN too).
Each time I plug out my LAN cable I have to reboot my system to get connected again. I even tried disabling and re-enabling the LAN adapter, but the problem still persists. My OS is Windows 7. Can someone help me out on this?
