Wireless connection failed this morning

This morning my Satellite Pro laptop will not connect to my wireless network. I cannot isolate when the changes happened to the system, it presume it was one of the upgrades of Jaunty that did it, I've not done anything at all on this machine. Here is the relevant data:-

It looks like the system attempts to connect to the router but fails. Any suggestions that might help?

didnt no new ubuntu was out for testing yet but any way did u install wireless drivers ?

Its been running fine under Jaunty for weeks, then this happened this morning, something must have changed, do not know what. Excluding the possibility of a hardware fault its seems more likely that an upgrade has caused it.

dont no if this applies to u but u could try installing madwifi drivers

or re isntall your wireless driver for ubuntu if u did manual install drivers

what did u exactly update ?

Thats an idea Markg48, however as I want to keep this laptop as a vanilla Jaunty install (for testing) and keeping it uncomplicated. I do not really want to depart from Jaunty.

The machine is only used to test Jaunty so I am not desperate to find a unconventional work around. However I would like a fix for it:p

It is a bit of a puzzle as I cannot quite understand when and why this happened.

did u update the kernel coz u need to rebuild drivers if you do that

:D downloading jaunty now alpha 1
