I use Ubuntu 12.04 LTS and I've been experiencing the following problem recently.

When I connect to the Wi-Fi network of the router A, the Internet connection speed of every other host in that network slows down to 0.1-02 Mbps, while my connection works properly - 20-25 Mbps. Then I connect to the router B which is a little far from A, then the all hosts (but me) of both A and B experience the same problem.

I guess there are some problems related to wireless interference, but I'm not sure, and I don't know how to fix it.

P.S: When I switch to Windows 7, everything works properly.

EDIT:

Details of the wireless device:

Broadcom Corporation BCM4313 802.11bgn Wireless Network Adapter [14e4:4727] (rev 01)

I suggest you try the other available driver for your device. Please open a terminal and do:

sudo -i
apt-get purge bcmwl-kernel-source
echo "blacklist b43"  >>  /etc/modprobe.d/blacklist.conf
echo "blacklist ssb"  >>  /etc/modprobe.d/blacklist.conf
modprobe brcmsmac
exit

It may take a reboot.

Are both routers using the same channel, or close? As a rule, close wireless networks should be separated by at least 2 channels (or more, if you don't interfere with other networks in the area).
