hey i'm trying to get my bluetooth connection to connect two host with pand

on both hosts I run

hciconfig hci0 up
hcid
sdpd

hcitool cc address_of_device_A

"hcitool con" shows active connection

so on host A i do

pand -n --listen --master

and from host B
pand -c address_of_device_A

i have /etc/bluetooth/pan/dev-up files configured so the interfaces bnep0 on both mashines come up

everything works ok- i can ping the mashine -and even using masquerading connect to the internet. i can ping hosts on internet and i could even enter a www page but
after some seconds when the transfer is high the connection just disapears
any clue?

the funny think is i have 2 usb bluetooth dongles of different brends and ping works both ways. but when i want to open a www from host A on host B it works and opening www from host B on the host A crashes the connection and i have to do the pand -c thing again

any clues?
