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?
To quote the RealTek engineers, "The rtl8187B card with VID 8198 is only for
Toshiba. But It is regrettable that we can't provide open source of that,
because we have some agreements with Toshiba." All that they will say is that
the part is different.
We have the data sheet for the RTL8187B, but I have seen nothing about a
watchdog timer. I would send you the data sheet, but it is not clear that I have
the right to do so. I'll explore that aspect separately.
Have you run this card with ndiswrapper? If so, you should be able to use usbmon
to dump the traffic and find what is being sent to the chip by the Windows
driver that the native driver does not. Perhaps a timer reset will be found that
way.
The open-source RTL8187 driver is still very much a work in progress. We have a
couple of patches on their way to mainline that you should try before you do
much further work. I'll be sending them to you separately.
