Pavel,
I see about the same with a bluetooth usb adapter. Suspect that is about what
you should see with bluetooth - its not designed for speed. It would be really
nice to be wrong though...

so you say that the Nokia 6230 has PAN Profile support and you don't
need any PPP crap to get Internet access? This would be the first phone
I have seen so far.

The initial pings look good, the rest is very bad.

The transmit timeouts shouldn't be there. The question is now which side
is at fault. The host or the phone?
Please do a "hcitool info <won't tell you>" as root so I can see which
what chip we are dealing. Also "hciconfig hci0 version" for your card
would help.
You can also use "hcidump -X -V" to analyze the traffic.
Regards
Marcel
