Please help with my Wifi speed.

 

 

 

Spark Gigabit connection. Standard 659b router/modem (wifi disabled). Wired connection (port 2) to Ubiquiti WAP AC LR, setup 1 primary SSID, plus 3 guest SSIDs.

 

 

 

Speedtest (on Android phone and Ipads on 2 and 5 freqs) showing speed of less than 100Mbps (upload and download).

 

 

 

What setting did I missed or set wrongly?

 

 

 

Thanks in advance.

 

John.

I've got an LR too and unfortunately I'm connected at low speeds all the time.  My Elitebook X2 Windows 10 tablet via WiFi to the LR is currently connected at only 162mps rather than something higher, even though the LR is connected to the network via a 1gb ethernet.  The LR isn't really a great AC access point for speed but it does have a longer range than the others.

162Mbps is a great speed to get over wifi!

OP - you need to check if your client is connecting via 2.4 or 5GHz, how many chains your device radios have, congestion on wireless bands etc. There is a ton of things that could cause this.

You could buy the flashiest access point ever and if your device is 2.4GHz single chain, you will still only get 20-40Mbps.

Speed tested on both 2.4 and 5GHz. 

 

5GHz a bit better than 2.4 but still below 100Mbps.

Check the network cable too from the AP to switch/network - could be that its got an issue and limiting throughput to the AP.

How wide is the 5 GHz channel??

What devices exactly are you using? 

 

Remember many older iPads are only single chain - and there are plenty of Android phones that are also.

Can you please confirm that the AP is definitely connecting to the router at gigabit (you can check this in either the app/controller or on the Huawei itself) and also how wide is your 5GHz channel. 

 

I have installed tons of these and they perform outstandingly. Often see over 400Mbps real TCP throughput on them with a 2x2 client. 

 

 

 

Edit - I just re-read and see you have multiple guest SSIDs. 2 things - do you have guest portal setup on any of those, and if you don't (after confirming gigabit link and 80MHz channel) have you tried disabling all but one of the SSIDs and see if there is a change?

 

 

 

Also as has been mentioned by the others too, what exactly are the clients, do they definitely have 2x2 AC cards. 

 

 

 

Another thing too - I assume you can reach far over 100mbps with a speedtest from a wired client?

Updates:

 

 

 

Changed WAP channel width from default 40 to 80Mhz.

 

Now getting 190Mbps on Mate10 pro.

 

Thanks everyone.

I get 350-400 on an 80Mhz channel with my mi mix 2, so I think something is still a little low there.

 

 

But yeah, 80MHz is needed to get decent speeds on 5GHz, but at the expense of using so many channels that you can only really run 2 non overlapping AP's since the DFS channels are so badly supported and problematic.

Yeah, you should be seeing better speeds with a good signal - pretty sure that phone has a 2x2 radio - it should negotiate 866/866mbps with the AP and you'd ideally see around 45% of that in real world throughput. However doing a speedtest is not necessarily the best way to test this. 

 

 

 

For example on 'gigabit' fibre with a OnePlus 5t (2x2 AC) I've seen speedtests around 380mbps with the speedtest app.

87m away from a unifi AC-M outside on the garage, at the road and getting ~200 on 5GHz speedtests when I was bringing the bin back in. 80Mhz set to ch 112.

My HD one is on 160MHz now they have added support for it. Had an 840 speedtest on the laptop I put the fancy intel card into on one occasion.

Using 80MHz channels on outdoor APs is not really a great idea, but indoors the signal doesn't propagate very well so it's a bit of a non-issue in all but the most built up areas.
