ralink 3290: still lots of misc errors reported by Iwconfig with 3.10 + HD streaming on WiFi fails
I just bought a HP netbook for my son equipped with this chipset. I first tried linux 3.9.7, got WiFi working badly but working. Saw fix for TX power in 3.9.9. WiFi became more reliable but still had a lot of TX, and MISC errors reported by iwconfig. While laptop is now usable for internet browsing, trying to play HD tv via XBMC + tvheadend fails miserably due to WiFi data rate and WiFi errors while other PC at home do play without problems.
Saw the fix in 3.10 for TX errors and indeed the TX errors dropped to 0. However, the MISC error count in turn rose (Downloading linux-3.10.tar.xz on 3.10 reports 550 misc errors). So there is still some problem with this chipset. I know support is experimental but I would be glad to test any patchif possible on 3.9.x as on 3.10 I have no ATI driver available at the moment and thus HD decoding is out of reach anyway.
Using ralink proprietary driver on linux recent kernel and amd64 is a no go(does not compile due to API change + lots of INT32/pointers conversion)but may be the driver code could shed some light for people with adequate knowledge...

Do you mean that 3.10 perform better than 3.9.9 ? I do not see any rt2x00 fixes between 3.9 and 3.10 that are not yet applied on 3.9.9. I can see only some cleanups and new hardware support patches.

we post new patches there, but currently we do not have any pending RT3290 fixes.

From memory I think I had a lot of reported TX error with 3.9.9 and they are now gone with 3.10 but the number of misc error reported by iwconfig is still high with 3.10. But you are right the fix for TX is still in wireless git and does not seem to be in 3.10. As I checked several git trees I mist have been confused...

OK. Next radical solution is to open the laptop and change for another half mini pcie card... Quite difficult to find one reliably even if there are some available on ebay.
Thanks for taking the time to respond...

Unless I'm really tired, this patch is in 3.10 and not in 3.9.9 :

You have right, I missed that one. It's on 3.10 but not on 3.9. We could post it to 3.9 -stable, but since 3.10 is now realised, 3.9 will become end of life probably.

Usually there is a small overlap at least until .1 or .2. For me it fixes reported TX errors but cannot test if it also fixes link quality/throughput due to lack of AMD/ati drivers.
Thanks again for your time.
