Really odd wireless problem
1) Dell running home rolled ubuntu 12.04 remix
2) Lenovo running same
3) Android tablet
Got a new router: b/g/n
Devices one and three connect just fine to the new router and anything else
Device two (Lenovo) will connect to anything *but* the new router
The lenovo is running a BCM4313 b/g/n according to lspci, but according to iwconfig it is running a/b/g mode.
(I'm using bcmwl-kernel-source for the driver. I've tried other drivers in the past and had lots of issues with them. This is the first issue I've had in months with this driver on it .)
Now I know there are issues with n in Ubuntu in general, so I tried using modprobe to temporarily disable / enable n. It made no difference.
I also tried taking the router out of mixed mode and setting it to b/g only. That also made no difference.
And I've already checked for noob mistakes like blocking / not allowing the MAC in the router's fiters.
I'm stumped. Anybody got any ideas?

Update: On further testing it looks like the Lenovo will only connect to *unsecure* wireless networks. Which makes no sense at all.

OK, this is really starting to tick me off. I got out anothe router: no go.
I found a bug report from 6 months back saying I needed to roll back the driver : no go.
I found a new "fixed" driver: no go.
I killed the built in wifi in BIOS and plugged in a usb wifi with a different chipset that is plug and play on *nix and the damn thing still will not log in to a secure wifi! WTF!?

Sounds like a bad wpa supplicant conf to me maybe
Like maybe the pass phrase is bad in that conf files. Just saying.
Edit: may help, maybe not
12.04 - How do I bring up my wireless network at boot? - Ask Ubuntu
Posted the Ubuntu links because Ubuntu has their own way of configuring files and naming them vs Arch.

Thankx for the links roky, but it's a no go. I've chased it as far as I'm going to. I went through what you linked to and dug up a bunch of stuff, but no solution. It looks like various ub distros are having issues with the BCM 4313 that involve the kernel, the drivers, networkmanager and wap supplicant and none of the fixes I've tried have worked. I'm going to flatten it and start over.
