Hi, I have problems with my Broadcom BCM4313 wifi card while using brcmsmac module. The wifi signal is terribly weak. When the distance between my laptop and AP is more than ~5 m the network is not visible at all. When the laptop is closer, it connects, but it is very slow due to weak signal. I have to sit next to AP when I want link quality more than 60/70. If I use Broadcom hybrid driver - wl - it works normally (but has different problems...). I tried to use three different wifi networks with this combination and all of them had the same problem. ----- My setting: $ uname -r 3.8.0-rc1 I applied the patch from: http://marc.info/?l=linux-wireless&m=135635090121154&w=2 The same with 3.5.7 gentoo kernel. ----- wavemon info: (with brcmsmac, ~5 m between my laptop and the ap) ┌─Interface──────────────────────────────────────────────── │wlan0 (IEEE 802.11bgn, WPA/WPA2), ESSID: "ihome" ├─Levels─────────────────────────────────────────────────── │ │link quality: 23/70 │====================== │ │signal level: -87 dBm (2,00 pW) │======== │ │ ├─Statistics─────────────────────────────────────────────── │RX: 3 8178(2,41 MiB), invalid: 0 nwid, 0 crypt, 0 frag, 3 misc │TX: 4 1789(779,619KiB), mac retries: 31, missed beacons: 0 ├─Info───────────────────────────────────────────────────── │mode: Managed, access point: (not relevant :-)) │freq: 2,437 GHz, channel: 6, bitrate: 5,5 Mbit/s │power mgt: off, tx-power: 19 dBm (79,43 mW) │retry: long limit 7, rts/cts: off, frag: off │encryption: n/a (requires CAP_NET_ADMIN permissions) ├─Network────────────────────────────────────────────────── │wlan0 (UP RUNNING BROADCAST MULTICAST) │mac: (not relevant :-)), qlen: 1000 │ip: 192.168.1.103/24, bcast: 255.255.255.255 └──────────────────────────────────────────────────────────��.n��������+%������w��{.n�����{���zW����ܨ}���Ơz�j:+v�����w����ޙ��&�)ߡ�a����z�ޗ���ݢj��w�f
