One of our windows 7 laptop cannot connect to our wireless LAN whereas other laptops are able to connect to the same WIFI without any troubles.
When an ethernet cable is connected and wireless connection is turned ON, it says WPA-PSK2 signal is active with 54 mbps. The wireless adapter is getting an IP address of
10.10.10.1 and the ethernet adapter with
I tried to ping both addresses from the modem and there was 50 %, 75 % and 100 % packet loss to wireless adapter and ethernet adapter has no issues.
We use a special DNS addresss supplied by the ISP and the ethernet LAN internet connection is working ok. I tried to ping another computer when wireless LAN only is enabled, it couldn't ping to other computer on the network.
So there seems to be some problem with the wireless adapter and/or driver. But when I took that laptop to a different WIFI, it connected without any problems.
