#8 broadcom f5d7050e works, but gets hot and looses connection


My new broadcom f5d7050E usb wlan stick works great with your driver and kernel 2.6.28.
But it gets hot during work and looses connection, even if I set txpower to 2dBm (normally 18dBm with some other usb wlan stick)

dmesg sais:

rtl8187: 8187B chip detected. Support is EXPERIMENTAL, and could damage your
hardware, use at your own risk
phy0: Selected rate control algorithm 'pid'
phy0: hwaddr 00:1c:df:36:5d:8a, RTL8187BvE V0 + rtl8225z2
usbcore: registered new interface driver rtl8187


  • I have a LogiLink wireless USB adapter, kernel 2.6.29 (on ARM). Here is dmesg output:

    I am measuring current draw and it is 400 mA. The adapter gets extremely hot. Changing txpower does absolutely nothing to the current draw (although when I type iwconfig wlan0 the settings appear changed). Setting 'iwconfig wlan0 power on' does nothing. I tried 'iwconfig wlan0 power period 1' - it does not work:

    Error for wireless request "Set Power Management" (8B2C) :
    invalid argument "1".

    Apparently the driver thinks that it can change txpower, but it cannot :). Please help me to solve this problem. Is there any documentation available? Are there ways to debug wifi drivers? Thanks
