Hi,

I am using Linksys E1200 router for wireless network, which recently for some reason get knocked off whack. It was not a big problem though to reset the router and reestablish network, all PC and mobile devices are now connected. However, my RHEL655 box (Dell Optiplex 745) that uses Dell 1180 wireless USB adaptor still cannot. There was no change in router settings, access control, etc., all remained the same. Here is output:

Apparently prizm2 driver is loaded, it was working just fine before the router had to be reset. And what the heck is Universe and how to reboot it? Rebooting the box does not help - the log shows red Fail next to network and says No Link. The adaptor also slowly blinks.
