My wireless internet has been very slow and unstable after installing arch. I've been trying to google the problem but to no avail. It's too slow to load speedtest.net and it keeps dropping. It works fine with ethernet though.
I'm using a BMC4313 broadcom chip with the brcmsmac driver

try with this
# iw reg set BO
# iwconfig wlp2s0b1 txpower 30
Set higher or lower mtu and check:
# ip link set wlp2s0b1 mtu 2048
OR
# ip link set wlp2s0b1 mtu 512

Thanks for the reply!
I get this error though :(
iwconfig wlp2s0b1 txpower 30
Error for wireless request "Set Tx Power" (8B26) :
