MR Firmware 27 and 28 issues

[longaair]

Hi,

Just wondering if people are still noticing performance issues on either of these firmwares? Admittedly, I haven't checked the logs to see what they are saying.  But I have had users constantly complain about drop outs and overall slowness on these firmrware version.

The fix in every instance is to revert back to 26.x and  the problems are solved instantly.

@longaair are the people having issues perhaps using Intel WiFi 5 chipsets like the 8260 or similar?  I found that these chipsets cause issues when going into power saving mode, which is pretty much all the time when the laptop is running on battery power.

The solution is either to disable power saving or the MIMO specific part of it if you can.

Or is it a more general issue?
