I have recently updated my Ubuntu operating system to Ubuntu 9.1. All previous settings have been carried forward except for my wireless connection. As far as I can see the wireless connection should restore automatically but when I am asked for my password the program freezes. Can anyone advise me what to do to restore the wireless connection?

What kind of wireless card is it? (Broadcom cards have issues. You can hack a workaround by using ndiswrapper which often times will band-aid-fix an issue.)

Is the wireless card internal, USB, or PCMCIA based?

Did you check dmesg to see if the card was loaded?

(For example: dmesg | grep wifi0

What does ipconfig -a show?

I highly recommend the Atheros cards.

Hi Ron,

Thank you for your reply. The card is a PCMCIA and the wireless modem is a TP-LINK TL-WN510G/TL-WN550G/TL-WN551G. However my laptop (IBM Thinkpad) could not detect the wireless connection so I reinstalled my original version of Ubuntu (version 9.04) and had no trouble connecting to the internet through the wireless connection.

I have read that when Ubuntu versions are updated insufficient attention is given to retaining existing wireless connections hence the trouble with version 9.10 There are a number of posting on the internet about this.

Many thanks for the trouble you have tak

I had issues like that going from 9.04 to 9.10, so I can relate. Glad you got it going, but fyi as well, 9.04 reached End of Life recently. Have you tried Ubuntu 10.04.1LTS yet?
