Lost Wireless Internet connection


Besides being a newbie, I installed ubuntu 6.06 LTS (Dapper) on my dell i8200 laptop (only OS). I am using a linksys wireless card WPC11 v4 that was detected on install and was working fine. Used the internet for several hours, shut the computer down. Next day no internet and no email.

iwconfig and ifconfig show that the card is installed and recognized. When i go to the connection properties it shows that i am connected with send and receiving packets and a signal strength of 97%.

I have tried setting the static ip address manually and i have tried using DHCP.

I have tried reinstalling ubuntu to get back to my initial install but nothing changes. I am lost especially since the card was working like a champ.

Any suggestions.

Metaljaz-

Did you find out what was going on? I have very similar problems- works one day, not the next.

When I ping something on the internet, I don't always get the message about an unknown host, but I don't get replies either. Just sits there.

never figured out what was going on. I dropped the links card
and picked up a Warpstar triple wireless lan card which is an Aetheros
based card. Worked right out of the box. Was automatically configured
when i reinstalled ubuntu. Picked it up from a member in the forum.

After changing cards i found this thread. Check to see if it can be
helpful to you.
good luck.
