MT7915E AC or AX both slow speed

[bosukes]

I use Netis N6 Wifi 6 router, which is not officially openwrt device, but it was on LEDE. So someone compiled it for 23.05.0 here:OpenWrt support for Netis N6 router - #28 by 123serge123
It works great otherwise. I believe it will be supported at next release.
Although it had some wifi issues at first, he again helped with it.
So it uses MT7915E wifi chip. I tested all these just 1 meters from the router. On wifi 6, it can't do more than 350Mbps. Whereas I get over 500Mbps on my wifi 5 router, Tenda AC18 which is freshtomato firmware. It must atleast have 600mbps speed. I got 1gigabit speed. Is this normal for
Also it's very weak signal too. I pass a wall, and it disconnects.

First, calm down, your router works.
Post 2 links to tests via wired and wifi from

Bufferbloat and Internet Speed Test - Waveform

noting the negotiated connection speed.

Then install htop and in F2 unselect "hide kernel threads" and select "detailed cpu time"
then run test via fast.com selecting 30 30 60 60 in settings.
make one screenshot over wifi another over wired.

I dont get why. What am I gonna look for it? Btw here is my speed report. It says 650 mbit something but actually wont give me that. Is this wrong? Also, it is significantly worse signal quality than Tenda.

Produce textual information without your IP or mac addresses in it. Please.

cat /etc/config/wireless:

I mean
Output of

ubus call system board

to see what your hardware is.

Then 2-3 waveform speed tests

• computer to internet
• computer to arcadyan wired
• computer to arcadyan wireless

Then 1-2 screenshots from command line htop while running minute long test against fast.com

edit:24GHz HT20 would make 72 or 144 Mbps with N or double with AX

[bosukes]

Sorry wrong signal, 2.4ghz connects fine. But sometimes doesn't. Here is ubus call system board, as I said it's specially compiled.

	"hostname": "OpenWrt",
	"system": "MediaTek MT7621 ver:1 eco:3",

And the links to the tests demonstrating regression? You know its not like everybody now has a clone of your router in a drawer.

[bosukes]

Here is the wired bufferbloat test, and terminal at the side:

Now all these are wireless:

[brada4]

OK, internet connection is very good. How comes you failed to mention that you knowingly enabled hardware offload?
Wireless speed is representative of HE20 AX, nothing to improve there.

[bosukes]

So is it caused by that? I use gigabit connection so can't do without it. But I think there is some other problems, if I just move slightly behind a wall, it's signal gets soo low. Is this normal?

[brada4]

If wall is made of lead bricks or reinforced by steel mesh then for sure.
Check TX power in wifi settings.

[bosukes]

Sorry I thought USB didn't work, plugged in and out a few times, now it works. Must be some dust.

[brada4]

Here we resolve wifi signal issues, seems your router is lightning fast otherwise.
If router is stuck to wall then consider projection distance if waves cross the wall diagonally, like opposite far corner. Solution is to move router away from the wall.

[bosukes]

CPU usage is unneccesarily high when wireless, compared to wired. I think this must not be happening. Anyway, I'll maybe go back to LEDE, even though it's old. Sorry for taking your time. I can buy you some coffee if you send me your crypto wallet address or something. Paypal doesn't work here.

[brada4]

Sounds you are trolling, LEDE never met AX

[bosukes]

No I am not, it had some customized LEDE on it when I bought it. Not stock. Company definitely modded it to their needs.

[brada4]

Will not change basic physics of your wall. Good luck

[bosukes]

I assume there is nothing wrong with my setup then. Thanks. But the thing is, Tenda AC18 with hardware offloading enable, it would go till 600mbps. Which is tomato firmware, can't compare but still..
