I updated my dinosaur "Dell Dimension 8400" yesterday using a CD with Ubuntu 12.04.1LTS. When I did this I also deleted my Windows partition on the computer (I was never using it anyway). Since this update I cannot connect to the wifi network anymore.
When I install the ADSL cable into the computer it connects fine, but even after doing all possible updates the WiFi is still not recognizing any network. I'm thinking I might have deleted my driver when I deleted my Windows partition, but I'm not sure how to fix this (I'm not even sure this is the problem).
The wireless USB adapter that my computer is using is: Dell Wireless 1450 Wireless usb adapter, model = d1450u.
I guess you guys need more info, but I don't know what you need. Tell me and I'll post it asap.
