I have the following setup
Windows XP tower with nvidia chipset and LAN controller connected to a Comtrend CT-5361 router via ethernet cable. All was fine until a few months after I had added an TP Link TL-WR740N access point to extend the range outside, connected into the router via ethernet.
Now if the access point is connected to the router the PC says network cable not connected.
If i connect my laptop into the router via ethernet that works fine
There is no IP conflict - router 192.168.1.1 AP 192.168.1.2
Ive tried the PC as manual 192.168.1.30 and via DHCP but no luck
I can connect to the AP via wireless Ok as well
This problem didnt happen immediately after adding the AP so I think it may be related to when I cleaned up some malware from the PC using Malware bytes and combofix
