Problem closing ubuntu 11.04 linux wireless, now firefox won't connect
 

I am a fairly new linux user and I have a problem between firefox and linux.

I closed my wireless connection on my ubuntu 11.04 linux the other day and then tried to connect firefox and it won't connect.

HELP, Help, help. what do I do???

Hi CajunChief,

Can you please provide some more detail as to what exactly you did? What do you mean by "closed your wireless connection"? Can you open a terminal and type and post for us what you get? Thanks.

Also, just as a side note, this sort of thing isn't useful in helping us solve your problem. We know you're here because you need help, and we're here to try and work with you to find solutions that hopefully benefit us all.

still need help
 

zerodragon,

Hi thank you for helping.

I did an iwconfig and this is what it showed:


cajunchief@cajuncomputer:~$ iwconfig
lo no wireless extensions.

eth0 no wireless extensions.



As far as the side note, point taken...

wlan0 IEEE 802.11abg ESSID:"cajunchief"
Mode:Ad-Hoc Frequency:2.412 GHz Cell: 3E:E0:DE:54:6F:BF
Tx-Power=15 dBm
Retry long limit:7 RTS thr:off Fragment thr:off
Power Management:off

Thanks.

It seems like your wireless card and network are both detected, do you have the right network key?

The proper key
 

ZERODRAGON,


Yes the key is correct. I know that it is. I can't get the firefox browser to find the wireless internet. :(

Earlier you said can you explain what you did, exactly? Thanks.

Here is what i did
 

IN unbuntu 11.04 (now 11.10) I had clicked on the up-arrow/down-arrow button area and selected the Disconnect option under
the "wireless" area. and now I have no wireless.

can you reconnect/undo what you did? Can you see your network in the list of available wireless networks?

Here is my current status
 

I can get the wireless to connect. However when I open up the firefox browser I get the following message:

"SERVER NOT FOUND"

when it is looking for my www.google.com website.

Okay, maybe the problem exists with Firefox. can you tell me what happens if you try:

here are my ping results

According to your ping results, you are connected to the internet. When you open up Firefox, what exactly is the error message? Do you get it for every site you visit?

My firefox message is
 

" server not found"
