Slow Wifi with brand new Surface Book 2!!!

I've tried all the suggestions, and have had no luck...

But I HAVE found that this seems to be a 2.4 ghz issue.

I tried my hand with Microsoft support, and was at first impressed with their attempts to really dig down to find a resolution.... But then they asked that dreaded question about my network gear.... And I cringed when I said it, and I did say it..... "hardware VPN(SonicWall)", they then suddenly told me that they cannot help me at all.... LOL

Anyhoo.... I use Ubiquiti wireless AP's, and with that gives me some decent feedback on what's connected on my network...

My WAP's consist of somewhat dated "Outdoor" AP's(2.4ghz), and one new "Mesh" AP(2.4/5ghz) that sits in my home office...

I have a cluttered AP setup that covers every inch of my house, and continues to cover 3 acres of open grass....

But to the point... I get super poor speed tests when connected to any of my Outdoor AP's(2.4)... Poor = 3.5-10 Mbps...

I restart and sit within spitting distance of the new 5ghz.... And I get the same, but to only find that I'm still on the 2.4 bandwagon.... So after a couple of disconnects/connects to the same network/AP.... I finally get on the AC side of things.... and I then get wired speeds(115/20) in which is my ISP's speeds....

So this network card is not smart.... It takes a couple of tries to finally get to the best band....

It also appears that ABGN is broke and should at the very least get close to 54Mbps....

I can't rely on this laptop to do anything.... I cannot troubleshoot networks.... transferring files is painful.... And I just cannot trust this thing....

And after Microsoft support shutting me down because I had a hardware VPN in place, just makes me wish I would have gone to a ThinkPad or Dell....

Totally unhelpful and shame you cannot search and see the simplest of entries. Do you think so many people would post without an issue. Please stand aside and let people who have an issue pursue it. If you dont have a problem and you dont have a solution you have nothing to contribute. I have worked in computing for over 40 years and have very good pd/psi skills. The problem I have has been with me since day one of the >3000 dollar purchase I have only got by by using surface dock so far but I am very fed up. Like others I will soon invoke my warranty and get a new box with all the pain that causes loading a new machine (in excess of 2 weeks for all my SW) or I think to be honest get a refund as this is so unacceptable as others have said.

I see 228,000 entries in that search.  I have a synology RT2600ac router and I connect at 866.5 Mbps  Maybe you have to spring for a better Access Point?
