12.04, cannot detect wireless network after router reset
I have an IdeaPad S10e running Ubuntu 12.04 for the past 6 months or so and was using the wireless network without any problems.
Recently, somebody accidentally switched off the Linksys EA4500 router. After it was turned on again, my Windows 7 computer had no problems reconnecting but the Ubuntu 12.04 system does not detect any available wireless network at all.
Can anybody offer any specific solutions?
Thanks in advance.
