Which chipset for 802.11g

Hi!

I'm gonna buy two 802.11g cards to make bridge between two Ethernet
segments.
During googling I discovered there are two supported chipsets: Atheros
and Intersil. Did anyone have any expirience with any of these chipsets
? Which one would you recommend ?

BTW I noticed that it's possible to run those cards in AP mode, so it's
possible to make bridge instead of router (like in 802.11b, where it's
impossible to send packet with any MAC address). Does this feature work
? Did anyone try this ?

There's a couple of O'Reilly books that cover what you're doing.

Hi,

I've got the SMC2835W pcmcia plus their 11g router (Intersil). I've
stumbled on the host-ap mode -- it might work but as the router stays
an AP I can't try.

What I did is a lot of routing in the regular routing tables. If you
assign the WLAN bridge it's own subnet and both sides of it separate
subnets too I don't see why bridging on the tcp/ip level should not
work.

setup of the intersil drivers are slightly strange, they are not quite
supporting the wireless extensions yet and some features have to be
set by rather cryptic and not much documented setoid/getoid commands.
But they *do* work and development seems quite active.

Oh yes, if MAC level bridging won't work, I'll do it on IP level
(routing). From the one side it's even better - ARP broadcasts will be
separated, so i'll save some "air bandwidth". But MAC bridging is
transparent solution, some games and "Network neighbourhood" like to be
one one subnet (segment).

At last I decided to use D-link cards based on Atheros chipset, I should
have them soon, so I'll see how will it work.
