RTL8187: RTL8187B with id 0bda:8198

[johan henriksson <jhn98032@gmail.com>]

Hi!

I am trying to get the wireless card on a Toshiba Satellite L350
to work. The laptop uses a RTL8187b chip but unfortunately with an id of 0bda:8198.
I have tried the RTL8187 driver in the 2.6.27-rc1 release.
To make the driver accept the card I had to add the productid 8198 to the driver.
Now the card is detected and seems to work. I can ping another computer on the network
but for some reason the network just stops working after about 6 seconds.
There are no errors in the kernel log and if I reconnect with "iwconfig wlan0 essid myNet" the card 
works again for another 6 seconds.
I am starting to suspect that the RTL8187b has a watchdog timer like the RTL8181 that times out?
Does anybody have the datasheet for the RTL8187b?

Regards
Johan Henriksson
