Hi, The AR9271 doesn't have enough memory to support that many clients. It keeps some client state in memory in the AR9271. Fixing that requires quite a bit of firmware and ath9k_htc work.
The AR9271 and AR9285 have a smaller keycache, I think it's only 16 or 32 slots. It's certainly not 128 slots. So you wouldn't be able to do hardware encryption with that many peers. -a On 3 June 2014 03:34, Kanhu Rauta <kanhura...@gmail.com> wrote: > Hi, > > The latest Atheros driver for AR9271 chipset, it seems the driver is > hardcoded to limit the virtual interfaces to two! > > The previous USB driver for AR9170 chipset (carl9170) has the capability to > create/use > 128 interfaces > > i can see the commits on this regard i.e > (http://marc.info/?l=linux-wireless&m=134971207706144&w=2) > > i need to simulate more clients(like 32) on the AR9271 chipset.
