L41G-2axD wifi speed problem

Hello,

does anybody have a problem with wifi speed on L41G-2axD ( hap ax lite )? I just bought one and a can get max 10M (usually around 5M) on download and 30M on upload and ping and jitter is very poor (7ms ping and 94ms jitter). From factory it has 7.6 firmware, tried also 7.12 and 7.13beta1, setup was really simple (also tried quickset), but problem is always the same. I was testing it only with my android phone, but on the same table if I test this with hap ac2 i have 30M on download and 50M on upload and ping and jitter are ok (1ms ping and 0.5ms jitter).
I also tried another hap ax lite, the situation is the same.

Does anybody has encountered with this?

Odd … I can get around 400Mb on mine (tested from laptop on AX Lite, wireless to AX3, then towards internal iperf3 server).

Are you sure you selected a channel which is as free as possible from other radios ? (in 2.4GHz range it will be hard to find a clean channel on most places, so as free as possible is the next best thing)

Can you post your config ?

I am just testing in on my table now, before I put it somewhere to my customers:

/interface bridge
add name=bridge1
/interface wifiwave2
set [ find default-name=wifi1 ] channel.band=2ghz-ax configuration.country=Slovakia .mode=ap .ssid=test disabled=no
/interface list
add name=WAN
add name=LAN
/ip pool

/ip dhcp-server
add address-pool=dhcp interface=bridge1 name=dhcp1
/interface bridge port

Yes channel is free in my office, as i wrote on hap ac2 (also in my office but in active test with hap ax lite with wifi turned off), speeds were ok with the same test device (my phone).

Does your computer (device you are using to connect to hAP AX wifi) support 802.11ax ?

No of course … this is the problem?

I don’t see a channel/frequency being defined so it’s auto. Never use auto for maximum results… select the channel yourself.

What device do you use to test ? Can it take advantage of AX wifi ?
And where do you test to ? External speedtest server ? Best to use an internal server (then you know where your bottle-neck is).
What’s your ISP connection ? (up/down)

Edit: ah, someone made the same comment about testing device capabilities …

Of course the 802.11ax speeds can only be achieved if both devices support those speeds. If your computer has some older and slower wifi card, it will work at the speed of the old and slow wifi card, no matter how good your router model is.

Now it is auto, but already tried selected channels of course.
Test is against my own speedtest server (not using internet connection, everything is on my own network).

What device do you use to test then ?

Because even on AC2 you get really LOW speeds, considering you test on internal network.
Should be around 400Mb at least, when using 5GHz.

What if you attach computer using cable to AX Lite, cable from AX Lite to your network.
Then speed test.
Ideally I would like to see something like 900-950.
Then you know there is no other bottle neck at play.

I understand that. But what I dont understand is, that with the same equipment and conditions but only with different router ( hap ax lite vs hap ac2) I have different results and very poor ping with big jitter.


Hap ax lite is 2,4GHz only so I am testing the same thing on AC2 (only 2,4GHz).


Can you please answer ??
What device do you use for testing ?

Even only on 2.4GHz, you should see close to or over 100Mb on AC2.
Heck, I get close to 90Mb using a stupid mAP (and there the ethernet port is the bottleneck) !

If your PC has some 802.11b compatible card, 11Mbit is okey for it. So yes, tell us what card is used for testing

Setup is like this:

android phone → hap ac2 20MHz channel 2432 on N (1S) → my own speedtest server (librespeedtest)
result: 30M on download and 50M on upload and ping and jitter are ok (1ms ping and 0.5ms jitter)

android phone → hap ax lite 20MHz channel 2432 on AX (1S) → my own speedtest server (librespeedtest)
result: max 10M (usually around 5M) on download and 30M on upload and ping and jitter is very poor (7ms ping and 94ms jitter)

android phone → hap ax lite 20MHz channel 2432 on N (1S) → my own speedtest server (librespeedtest)
result: the same as above

tried firmwares 7.6 (from factory), 7.12 and 7.13beta1 always the same … download is poor, upload is better, but ping is high and also jitter. CPU is doing nothing max 18%.

It is ok that routers are capable of more speed I know that, but in this situation, i dont know why, but hap ax lite is really slower.

Thanks for these details.
Just one more note from my side - hAP ac2 is an overall higher class device, bigger antennas etc.

What android phone ?

Can you use laptop for testing ? Anything else with wireless capabilities ?

So I made another test with laptop (not phone), and speeds are ok, so it has something with the wifi card on phone … but I didnt have till now problem with my phone on speeds with any routers … If I want to put AX lite to my customers, I can run to same problems :frowning:

But what I have observed, that TX rate on registration table with the phone is really low (it starts at 1M) but during speedtest gets a little bit better to max 20M, but for the laptop it is from begging 270M-300M and doesn’t drop. Signal is almost the same for both around 43db.

You will always run into situations where a client device is responsible for slow speeds.
Nothing you can do about it (unless you can also sell them a new phone :laughing: )

It’s like the goverment builds a new road with very good surface and allowed speeds 140km/h and the driver with his very old car says “my car still does not go faster”. will he complain to government, or is this common sense that you need a new car to safely drive at maximum speed?
