Wireless Problem on Ubuntu 11.10

[noisysoul]

Hi, a few days ago I installed Ubuntu 11.10 (32bits) on my laptop (Samsung R430). When I try to connect to the internet using wi-fi a pop-up message asks the password as usual and after I type it correctly it shows a notification box telling me that I'm disconnected. If I connect the cable directly it works perfectly. Ubuntu 11.04 or any older gives no problem, I mean, it's not my router or my laptop, it's the OS (Ubuntu 11.10). I've read many forums and pages and lots of buddies out there are having the very same problem (or similar). I've updated and tried a few things but it hasn't worked.

Please help me out...
Thank you so much. Greetings from Chile.
Have a nice day, bye!

:p :p :p

I do hope Ubuntu prioritises the whole wireless issue as it seems very common and is now a major sticking point for many people. Everything else is just fine for me ..errmm...except for wireless. :o

i also have this issue hope they fix it

Hi,

did you find any solution for this bug. it is really annoying me.

and also this is not probably an os problem, it is exacly an os problem. wish they solve this immediately

Just wanted to add to this cry for help. I have a MiFi hotspot that works with pretty much everything I've thrown at it (Desktop on Natty, 2 android tabs, windows notebook, Natty notebook) but I can only connect very occasionally with oneiric on my notebook and then it tends to lose the connection quite quickly.

Without hardware information it'll be impossible to help. Can you post information on the chipset of your wireless card so we can assist? If unsure how, easiest is to just open a terminal and run
lspci and
lsmod and paste their outputs here for review.

Hi @TBABill

thank you for your assistance.

My notebook is a dell e6410.

the problem is, I can connect internet with wireless but some times it starts to asking username and password then it never connects again until restart or pass some long time. In our office we have many connections we can use, If this problem happens, I can't connect with none off them

[faruk.onder]

Hi,

how can we create a bug report for this problem. if anyone can create quickly, could he/she open a bug for it.

[tuxt]

have a look at this:

hi tuxt,

thank you for link, but I want to use with default settings and programs.

Please Help... The problem keeps getting worse....

[OwnSurname]

Same problem here: the wireless work nicely (on a Dell Latitude D630) until it gets disconnected. Then, it prompts for the password, and although it's correct, it's not able to connect anymore. Any help is appreciated, it's quite an annoying bug as the only option it works for me is to reboot.

[voradeaur]

Your problem is rather similar to that of my own... I can reboot the computer with about 10% chance of successful internet connection (also running 11.10.) Those that do not suffer this rather frequent failure (with the dialog box showing disconnected 7 times before quitting) doesnt seem to understand the horror this produces. Its a nicely laid out system I would love to use, however; given this problem... its not looking like a possible answer. I hope you get this figured out for both our sake.. lol

[mvsrinivas]

I installed Ubuntu 11.10 on my DELL laptop 2 days ago and I had no problem at all. The wireless detected my home Wifi network and connected as soon as I entered the KEY.

[OwnSurname]

Just to point out the obvious: everything works fine with the wireless, until it disconnects, and it can happen after many hours. Only once it disconnects, it's not able to connect again. Also, upon reboot, it always works fine until the next disconnection.
