Surface Pro 3 Slow WiFi - 72Mbps Max (driver)

So I got my sp3 yesterday and it was blazing fast on wifi. I did all the new updates and after doing so every web page was loading slow or timing out.

I did some searching and there a bunch of people with the exact same problem "Other forum"

I cant use my 5ghz network which is my wireless ac. I have a netgear nighthawk and the only way i can use this sp3 is by using the 2.6ghz now.

Please fix this. I'm shaking my head that first update screwed something up.... i already went through nightmares with my sp2 so this isnt a good start :( 

One more idea. If it was working before the update you may still have the drivers old version in your SP3 so it may possible to downgrade it. just an idea.

We have other people reporting the same issue here too.  It's hard to release a device using a new technology and make it compatible with all the other devices in the market using that technology. Eventually MS will fix this issues but it will take some time.

I've been speaking with a number of other friends/family/colleagues that also picked up Surface P3s on Day 1 and they seem to be having the same issues. 802.11ac compatibility seems to be the worst, but even 802.11n speeds seem to be worse than other stable devices.

Agree. I'm using 802.11n at 2.4 GHz. At 5 is not stable enough.

The last firmware update may be the cause of that.  Pro 3 models received a firmware update that slowed down WiFi and you may be able to perform a REFRESH and reinstall you updates - but - this time, if you see a firmware update, click on the list link just below it in the Windows Update panel and it will display all updates pertaining to it.  The one listed as FIRMWARE, right-click on it and tell it to 'hide' the update.  Then, go ahead and install the others.

Eventually, that firmware update will sneak back into the updates automatically but maybe, then, it will be fixed with a patch.

I don't have a Pro 3 myself "yet" but everybody who has RT and Pro models in the past that had troublesome firmware updates had to do that for function.

Give it a shot, you don't lose your files in a REFRESH.
