Hi folks,

Installed current snapshot -> compat-wireless-2009-02-05

Still trying to get to grips with the rtl8187 driver. Not sure at the
moment whether my current problems are the fault of the laptop hardware=
 or
the driver. Maybe someone who has a similar wireless chip would care to
compare notes.

My router is situated upstairs. I have, this week, changed it to a new =
one
with a 5db gain level antenna rather than the original that had a 2db.

I have no problems with my old laptop using the ipw2200 driver connecti=
ng
to either of my routers. I can walk anywhere in the house with doors sh=
ut
and still get a solid ping.

Sadly, it seems my new laptop is not so reliable...
- Moving around when constantly pinging causes the pinging to halt,
missing packets.
- If I dont use the network connection for a few minutes (think it tend=
s
to be when on battery but not definitely tested), it seems the wlan0 di=
es
/ goes to sleep / hangs. Not sure which. Sometimes it comes back with a
quick ping to the router. Other occasions I have to re-modprobe the
driver.

I thought it might be the hardware is not as powerful as my old laptop =
but
iwconfig reports both have a 20db tx value so figured they are connecti=
ng
with the same transmit power.

Wondered if it might be to do with cpu frequency scaling as the default
kde4 powersave settings have the following settings:
- AC adapter: cpu freq scaling =3D performance
- Battery: cpu freq scaling =3D dynamic (less aggressive)
(Changed Battery to performance to see if this makes any difference)

Either way if people have any ideas they could throw at me then I would=
 be
much appreciated as doing anything networky such as a quick google is
turning into a full blown network marathon!

Distro: Mandriva 2009

Happy to provide any more info as required.
