[SOLVED] No wireless signals. Wireless card is detected.
I recently bought a wireless router 54 Mbps 802.11g TRENDnet TEW-432BRP. I first test it on Vista and it worked seemlessly. I secured the router with WPA encryption shared key. I then rebooted the laptop to Kubuntu and the wireless worked there also. I was able to connect to the router by specifying the security key.
But when i started the kubuntu the next day, i was not able to see any wifi signals. The wifi connection was there (as i have saved it in the first go) in networkmanager but it was not getting connected. I tried rebooting a few times but no luck.
I am providing some debug info below. Hope it will help in finding the issue.
