I just received my 950 today, and once all the updates were on I too noticed I was connected to 2.5 ghz wireless and only getting a speed of 6-10mb dload on a 220mb connection, I switched to 5ghz only on the router and the 950 connected but after numerous speed tests it showed a dload speed of 0mb.
I tried what someone said on here regarding turning on Bluetooth and my dload speed connected to 5ghz went to 100mb dload, not the full speed but still better than nothing.
why on earth enabling Bluetooth affects wifi speed only ms know...
I just hope they release an update sooner rather than later as this is pretty poor since the problem has been ongoing for quite some time now
