Hi there,
At home, I have a wireless access point which is directly connected to rl1.
To eliminate the access point, I put a wireless PCI card in the machine,
and configured it for hostap mode.
A laptop running Linux is the wireless client. When the client associates
with the ral0 card, the connection is established but has a packetloss of
about 30%, and a noticeable amount of duplicate packets. When the client
associates with the wireless access point, the connection has no packetloss
and no duplicates. (Both tested using "ping -f", directly pinging the
access point and the IP adress on ral0.) I've tried to rule out things
like distance.
The wireless PCI card is a:
ral0 at pci0 dev 11 function 0 "Ralink RT2560" rev 0x01: irq 11, address
00:0c:f6:26:0d:b2
ral0: MAC/BBP RT2560 (rev 0x04), RF RT2525
I don't understand why there is such a large difference in characteristics
of the connection. Am I using the wrong type of card for such usage?
