Broacom issues

Postby Dans564 on Thu Nov 29, 2012 8:27 am

Hey everyone,

I have a Broadcom Corporation BCM4321 802.11b/g/n wireless card and Linux mint 14 cinnamon, with the STA wireless drivers activated through software sources.

I am having serious stability issues with this card and driver. When first booting, it can take anywhere from a minute to five minutes for wifi networks to be scanned, then another handful of minutes to join my home network. Also, once joined, my connection is super flaky. It drops out at random intervals, about 3 times every 10 minutes.

Anyone have any idea as to what could be going on here?

Thanks in advanced,
Daniel

Linux Mint is funded by ads and donations.
 

[SOLVED] SUPER slow wifi

Postby Dans564 on Fri Nov 30, 2012 12:19 pm

hey everyone,

Running mint 14 32bit here, on a custom gaming rig. I have a broadcom BCM4321 which historically at least, has worked fine with the STA driver. Yesterday, when I installed Mint 14 64bit, the driver worked like garbage. Took forever to scan for networks, and would disconnect constantly. Working off a hunch, I figured it was maybe just a 64bit issue, so today I installed 32bit mint. It seemed to work way better for a while, but now I am experiencing very slow speeds, and although the wifi connection stays open, I randomly loose internet access.

Here is the output of mintwifi.py:

Rather than invoking init scripts through /etc/init.d, use the service(8)
utility, e.g. service smbd reload

Since the script you are attempting to invoke has been converted to an
Upstart job, you may also use the reload(8) utility, e.g. reload smbd

Only one weird thing I can see is that my wifi is being reported as eth2, although not sure this would cause any problems. Anyone no what's goin on with my speed?

I have merged these two threads together as they obviously relate to the same topic.

two seperate installs, one is 64bit one is 32bit. Nature of the problem isn't quite similiar either. Yes both effect wifi, but they are very different symptoms.

compiling my own driver fixed it, a solution that didn't work when using 64bit. I guess they aren't the same problem :roll:
