In 8.0 people were able to stop the limited connection issuesI by disabling the selective suspend option in the Wi-Fi driver properties. I noticed that in 8.1 it went back to being checked enabled.
Ok, reduced my router to transmit at 71 mW (the default curiously) and now I can connect just fine 5 feet away. Apparently I was overwhelming my SP with the sheer power of the signal. That along with my electric personality just proved too much
Also even at 71 mW my wireless extender seems to still be in the green signal-wise so it's all good.
@mitchellvii, which driver version you have for the Marvell Avastar 350N on the SP? I switched to version 14.69.17056.73, 11/16/2012. Already 1 week no problems whatever anymore. A steady 270.0 Mbps connection, all the time. Maybe you can try it.
btw I have Selective Suspend enabled(default in 8.0)
I have the newer driver; however, since reducing the power on my router to 71 mW I have not had any connection issues. I think I was just overpowering it when nearby.
270 mbps? Holy God, what are you on, fiber optic?
