[lime-users] 5Ghz usb dongles

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
