Re: wireless connection problem of BCM 4312 LP-PHY wireless card with Network Manager

Hi all,

I installed Linux Mint Debian Edition which was based on Debian Testing on
my laptop. One problem I found was that my wireless connection was
frequently dropped off after some idling. And it was not predictable:
sometimes I left it overnight and the wireless was still good, but sometimes I just left for 10min and it was off. I used Network Manager (v0.8.3.999),
by which the wireless couldn't be reconnected successfully once it got
dropped . Command "lspci -vnn | grep 14e4" gave result:

04:00.0 Network controller [0280]: Broadcom Corporation BCM4312 802.11b/g
LP-PHY [14e4:4315] (rev 01)

And I used the package "firmware-b43-lpphy-installer" in Debian's repository to install the wireless driver. Before that I used Fedora 14 on the same laptop but it didn't have such problem (the wireless driver was installed
from rpmfusion repositories).

Right now I get around this problem by reloading "b43" driver once it
happens. But I have no idea whether it was due to the driver itself, or
Network Manager.

Could anyone please help? Thanks very much.

I'd uninstall NetworkManager and install wicd instead, giving it a test ride. It miraculously cured the flaky Broadcom wireless on my Squeeze laptop (slow speeds, erratic ping times, incurable disconnects etc.).
