Bug Description

Binary package hint: network-manager

Note: I use a bcm4318 card, and this is speaking from a gutsy install (though most of it applies to earlier releases) on a Gateway MX7515

The first time network manager tries to connect while using the bcm43xx driver, it succeeds. However, after a reboot it will attempt to auto-connect to the last used network and fail. All subsequent attempts to connect to the wireless network fail as well, even if the wireless radio is restarted.

Oddly enough, plugging a cable into my ethernet card, even for a moment, is sufficient to make network manager stop hanging and connect to a wireless network. (The cable can then be removed after dhcp configuration begins).

I would note that although I haven't tested plugging an ethernet cable in on a kubuntu install, it seems to have a similar lock up with knetworkmanager.

At least two friends of mine are cursed with a bcm4318 as well, and have had similar issues. In at least one's case, manually attempting to connect to the wireless network just after it begins attempting an auto-connect seems to work. I'll test plugging an ethernet cable in mid connection next time I get the chance.

Setting up a static connection to load on boot seems to have slightly more success, though really the best solution to connect that I've found so far is simply using iwconfig an dhclient from the terminal.

What follows is my full lspci -vvnn output, the wireless card is second from the bottom. I realize it's overkill, but given the only quick fix I've found outside a terminal is plugging an ethernet cable in to 'wake up' network manager, I thought there's the chance some strange hardware interaction might be going on. So here's all of it.

If anyone else has a 4318, or anything in the 43xx series and is having trouble connecting with the native driver (I know I've seen quite a few posts on the topic in various places) it would be nice to hear what if anything plugging a network cable in for the duration of the dhcp configuration does.

For the reference ... what driver are you exactly refering to by
"native driver"?

The bcm43xx module included in ubuntu's -generic kernel (with firmware cut of course)

I've tested it with ndiswrapper as well, which does work as expected. Both bcm43xx and ndiswrapper seem to configure fine from the terminal.

I have also tested it with a 64bit build of ubuntu installed. No noticeable change with the bcm43xx module in use, save perhaps a slightly higher probability than any given time I attempt to connect it fails (though I've never had much luck with wireless on 64 bit). Ndiswrapper also works fine on a 64 bit install, which surprised me, as I had never successfully used ndiswrapper and network manager on a 64 bit install.

All and all it's a relatively minor annoyance to me, but if someone with the same problem didn't know how to use a terminal it could be a show stopper, so to speak. I've yet to get a chance to examine a friend's connection but he says he is having what essentially sounds to be same problem, but on his Feisty install (and with kubuntu's knetworkmanager) and with a broadcom 4300 series card.

At the moment I am testing kubuntu in a 64 bit install and ndiswrapper at least works as expected. I haven't tested the bcm43xx driver with this kernel yet and knetworkmanager has updated once but last I checked it too had a problem connecting wirelessly with the manager unless a wired connection was present until dhcp finished.

If I figure anything else out I'll post here. I do know other people with bcm4318 cards and I'd say about half of them work perfectly through network manager.

So you say the real problem is dhcp hanging?
