Hi guys,
I'm revisiting an old issue. When we started with our network model
(cheap dual radio nodes), we used an atheros based USB dongle to add a
second radio to cheap MR3220 routers.
This was interesting for our first experiments but then we realized that
the ath9k_htc driver behaves horribly with these devices in adhoc mode.
We ended up using dual band routers.
The thing is that we are now facing a problem with 2.4Ghz band
saturation, even in very small towns, so the nodes are effectively
behaving as single radio in many cases, considering the 2.4Ghz path is
almost unusable.
So... I decided to take a look again at 5Ghz USB adapters.
I found this (2014) thread in the OpenWrt forum:
https://forum.openwrt.org/viewtopic.php?id=48248
where a guy says the RT3573-based stick Netgear WNDA4100 is behaving
well in 5Ghz AP mode. Found no information on people using these for
adhoc, but I'd like to give it a try. The rt2800usb is supposed to
support this mode.
Does any of you have any experience with this particular (or similar)
usb dongle in adhoc mode?
Cheers!
Nico
