Hi,
Recently tested various routers to find the most stable, with great WiFi coverage and that will give me lowest latency possible.
Tested: Netgear d7000 v2, d7800, TP-LINK VR600 v2, currently using VR2800 which is the best of the above.
My issue relates to strange WiFi download speed as all of the above routers give me maximum download speed of 59mbps on every speed test website out there. I can't get more than 59mbps (apparently it always shows 58-59mbps and never less never more) despite my sync being 80/20 and wired speed tests show 75/19. Upload seems fine. No matter if I am on 2.4 or 5ghz, very close or far away from the router it still is 59mbps. Of course I've tried changing channels, channel width and nothing seem to help. Tested on few wireless devices and all report the same. Very strange to me and seriously couldn't find anything about it on the internet. I'd understand it if my signal was bad, but it shows 850mbps on my phone and full bars (-32dB)
Anyone know what could be causing my download speed not being 74mbps over WiFi? I'd be very grateful for any help.

[It’s a long time since I studied all this so please forgive me if my memory has failed me.]
What sort of wireless NIC / device are you using on the other machine that you are using in testing?
It could be lack of MIMO multiple paths / diversity. If there are opportunities for reflection to create an indirect longer path or two as an alternative to the straight line transmission route, then that will double etc your total transfer rate with MIMO hardware. If the straight line route is the only route, then it may be slow.
If one of the devices doesn’t do MIMO, then your rate can be limited to ~65Mbps instead of nearly 300Mbps or 600Mbps or whatever, depending on how many antennae you have at each end.

I've tested it on 2x Huawei P20 Pro and Samsung laptop with Intel NIC. Samsung definitely doesn't support MU MIMO as it is very old laptop and not sure about P20 Pro. Any way to disable this feature?

Its not about MU-MIMO, but MIMO in general, but that would already be reflected in the link speed shown. If your phone is showing around 866Mbit, that would suggest 2x2 MIMO, I can easily pull 700Mbit (tested to LAN, don't have broadband that fast) at that on my S10 (although for some weird reason Windows does less at the same link rate, more like 500-600) so this is really weird.
What I tend to do is run iperf3 as a server on a wired device then run iperf3 client in reverse mode "iperf3 -Rc <serverip>" to test the WiFi performance of the client. Magic iPerf is good on Android.

How many neighboring wireless networks can you see?

How many neighboring wireless networks can you see?
There are 2-3 neighbouring routers using the same channels but changing 5G channel to another doesn't make a difference. I feel like it would easily hit 75mb on Speedtests but something is preventing it to reach the max speed at it locks up on 59mb.

How many devices you have connected at the same time. Do you have QoS setup?

Tested with none and few devices connected - no difference. Same to QoS enabled or disabled no difference

Can't you even get around 70 Meg when standing next to the router with your smartphone? Can you run speedtests using the speedtest.net & fast.com apps on your smartphone?

No, not even being 5cm from the router. 59-60mb constantly

Always speeds like that.

I've used 2 out of the 4 routers mentioned in the 1st post and they both achieved considerably more than 60Mb/s on 5GHz AC.
You could try forcing 802.11ac and see if that helps.
Open the VR2800 web interface then go to..
Advanced > wireless settings > 5GHz
Set mode to 802.11ac only
Channel width 80
Leave channel on auto, or..
use an app like "WiFi Analyser" to find a quiet 5GHz channel (I would be doing this anyway).

Thanks for suggestions j0hn, unfortunately none of these helped. It actually is even worse.

Have you tried taking your lead gloves off when holding the phone? ::)
Seriously though, this is bizarre.

Personally I’d be taking the view that wired speed tests of 75Mbps, vs WiFi of 60Mbps, are “about the same”. In other words, covering both scenarios, we have a speed of mid 60s plus/minus 10%.
Wireless can never be as good as wired, the best it can do is to be very nearly as good, and then only under ideal conditions. And speed test sites are not an exact science. :)

Not really. Even a 2x2 802.11ac link has a theoretical capacity of 866 Mbit/s - that's more than enough to saturate 70 Mbit/s.
A small throughput reduction I get but really shouldn't be a big deal.
No FTTC customer should be unable to saturate their connection via a decent quality, properly configured WiFi signal on 5 GHz and be fine on 2.4 GHz unless there's interference or other issues.
Saturated 375 Mbit/s no problem, just did a test on a basic 2x2 802.11ac radio and seeing >500 Mbit/s.

I used to have problems saturating my broadband on 802.11n as I recall, even though WiFi to LAN was dramatically higher than my broadband connection. I never could understand why that was, I assumed some weird conflict with how it was handling the traffic.
Since moving to AC though I don't think I've had that problem. The fact different hardware is causing the same issue is puzzling, I could only think there is some very odd interference in the 5Ghz band that is killing the WiFi performance.
I do sometimes get an odd speed reduction across the road between WiFi to LAN and WiFi to Internet, but that is going to a 5Ghz AP, then over a 5Ghz PtP link, so there is a lot of scope for thing to go awry even when the channels aren't overlapping. I think maybe latency differences and packet loss over all those layers can cause strange issues.

The fundamental reason I assert that WiFi can only ever be very nearly as good as wired ethernet, and often less good, is that with the former a real-life non-zero error rate is quite normal. With ethernet such as 1000 BASE-T, particularly when cables are a tiny fraction of the 100metre length limit, real-life error rates often remain absolutely zero for quite long periods.
802.11 error recovery procedures are very good, stunningly good if that’s a word. But good error recovery is not quite as good as not having errors. Stress an IMHO here, a quick google has failed to find any convincing analyses to confirm or deny my suggestions. :)

I will look closer to router settings, I remember that I had issues with speed on my mobiles when after one fw upgrade PMF (Protected management frames) was on by default. At this time I had speed link between router and mobile phone 866Mb/s but broadband speed was only 2/Mb/s on speedtest, took me few dsys before I found that, on PCs or laptops all was perfectly fine. Once I turned this off full speed on mobile phones was achieved without any problems (71Mb/s in my line best days).

There is no such option in my router.
Interesting this is that when I choose 31173 servers no matter what location on speedtest.net I am getting 73mbps on WiFi, all other servers give me fixed 59-60mbps and also different speed test websites give me 59mbps as well. So strange
-
For me best results on speedtest.net give London servers (Vodafone and 3UK) even that I live 120 miles from London. Closer servers barely 50Mb/s especially during the day, and now with all this lock down.

That used to be the case for me on 802.11n, even when I could do WiFi to LAN transfers FASTER than my broadband, speed would always be below my broadband speed when going online.
I can't remember if it went away when I moved to AC but I can confirm I have no such problem with the nanoHD. I can get exactly the same speeds on WiFi as wired, which you'd think so considering I can do 700Mbit WiFi to LAN if I worshipped the right deity that day, or 400Mbit if I did not.
