[Solved] WiFi Connectivity Issues, connection drops after a bit

Using NetworkManager
When I connect to a wireless network when my laptop starts up, it connects and I go along with whatever I would be doing.  After a seemingly random interval, the connection decides to drop, and the only way I can reconnect is by rebooting.  This is particularly annoying after I resume from hibernation and I then have to reboot anyway right after I resume.
Restarting NetworkManager doesn't help.  Wired connections don't cause any errors.  The problem is not the wireless network, every network gives me the same problems.  I have a Broadcom wireless card, BCM4313 and am using the brcmsmac driver.

Here are the outputs of dmesg:

Any help you can give would be greatly appreciated, let me know if you need any more information.

EDIT: Marked as solved, haven't noticed problems recently, it seems it's been fixed somehow.

Re: [Solved] WiFi Connectivity Issues, connection drops after a bit

almost certainly you're a victim of the same dodgy kernel commit as me.  The commit that broke broadcom (4313) wifi has been reverted, should be fixed in kernel 3.8.8.

Re: [Solved] WiFi Connectivity Issues, connection drops after a bit

I had a similar problem: https://bbs.archlinux.org/viewtopic.php?id=155821

Maybe this will sort You out but I am just guessing.

Re: [Solved] WiFi Connectivity Issues, connection drops after a bit

I upgraded my laptop to 3.8.8 tonight and brcmsmac (4313) wifi works again instantly after suspend/resume which was the problem for me.

Re: [Solved] WiFi Connectivity Issues, connection drops after a bit

Considering that you are using broadcom, have you considered trying one of the other modules that are typically available for their chipsets?  I think for brcmsmac, I think you can use the b43 firmware and module, which is open-source reverse engineered.  I have very little practical experience with broadcom, but through these forums I have seen many who tout success with the b43 setup.

Of course, that is, if your problem returns, which I hope it doesn't.

Re: [Solved] WiFi Connectivity Issues, connection drops after a bit

no, I hadn't considered it to be honest.. this is the first problem I can remember having with the wifi on this machine.  But, I always strongly prefer open to closed source so I'll definitely give it a go at some point soon.. thanks for the heads up.

Re: [Solved] WiFi Connectivity Issues, connection drops after a bit

I updated to the latest kernel, but I'm still having problems... will try the other solutions mentioned.

Re: [Solved] WiFi Connectivity Issues, connection drops after a bit

It seems it is some sort of problem with the driver.  Unloading and reloading the brcmsmac module fixes the problem without a reboot.
