Slow wifi on Flint AX1800

danbratu · 2022-11-29T00:30:18.620Z

first time updated from 3.214 via uboot with .img to 4.0.1 beta. after that updated with .tar for every new beta versions until the stable 4.1.0 (or beta 4.1.0 release 6).
i’m using channel 36 as all other channels are used by my neighbours apart from 36. if i’ll set it on auto will pick 36 so… 36

and wired:

wired21440×900 108 KB

and VPN (wireguard) wired (raspberry pi 4) speeds (server is 1600 miles away therefore ping is a lil bit high) but not important for my needs with vpn:

i didn’t use uboot to update it, i just grabbed the .img and uploaded to the router via admin panel.
Not sure if that the correct way? but it worked, would that have to do anything with it?

The 277, 463 speed test is on 5G wifi? So what is tyhe 566, 599 speedtest? Also the same right?

I notice that the speedtest server is different. Can you choose the same server?

subzero06 · 2022-11-29T01:39:34.993Z

That wasn’t me - that was the other user’s picture.

alzhao · 2022-11-29T01:42:13.661Z

Sorry for messed up. Can you private message me your mac address?

Also can you change the TX power from MAX to High and test again? Also try change speedtest server.

danbratu · 2022-11-29T08:42:41.511Z

in am located in UK, he’s in US. picking the same server will not be relevant. i’ve picked a server 80 miles away and another one 60 miles away

the answer to your question might/should come from a GL.iNet engineer/developer. i am just an user…

This is for sure a problem, M1 max over here with 1200mbps roof, i was getting around 700-800 mbps symmetrical bandwith, now not getting over 300mbps but getting OK upload of 500-600, is this bug getting fixed?|

elpmeh · 2022-11-29T19:29:41.243Z

okay so I have wifi on nother laptop thats the same, so it rules out the m1 max configuration, its the wifi settings, they where fine no change but the beta updates to the newest release 6 or whatever it is as of now for the ax1800 flint, fix this please

subzero06 · 2022-11-29T19:33:54.967Z

Thank you - im not the only one then.
I tried on asus windows laptop, apple macbook pro, iphone 12 and alienware laptop. Same issue slow wifi after 4.x firmware update.

elpmeh · 2022-11-29T19:36:17.708Z

aye, the team here will fix it i reckon, there are enough bringing it up:) I tried all the TX settings nothing changes it, it will hve to be a FW update by looks of it

hansome · 2022-11-30T02:19:51.512Z

Hi, could you have a try to set “Wi-Fi Security” to “OPEN” and “Wi-Fi Mode” to "11a/n/ac"to test if it’s hw issue.
and please run command:

iwinfo wlan0 asso

to get some info about wifi station.

i just did - same issue - this is more of a firmware issue - not hardware.

hansome · 2022-11-30T07:06:43.669Z

Please try to fix the channel to 36, and not too near from ax1800 flint.

elpmeh · 2022-11-30T12:00:06.447Z

ok my pervious setting thts carried over the last 4 or 5 betas it no longer selectable, CH61 is gone in standard or luci settings

also in luci ifi select AX and any of the channels it saves and disables the antenna, its a Firmware issue please fix asap

elpmeh · 2022-11-30T12:01:11.600Z

ch 36 or any them do not change anything I’m afraid, thank you though, we need those wifi speeds unlimiting please they are bad with high latency now

elpmeh · 2022-11-30T12:14:54.230Z

It may be the TX power thats glitched as In luci once set to max transmiting power I can only choose

Current power: 24 dBm

as the max output, but if i choose the max setting 100mw it fails to connect

this seems to be part of the issue

4.1.0 release 6 broke download speed fine upload

4.1.0 release 5 broke download speed fine upload

4.1.0 release stable release: broke download speed fine upload

download is not climbing over 360meg upload not really climbing over 660 area

before at an unknown configuration and time the D&U it was 720 -800 mbps symmetrical, in the same room same scenario

this is on a connection that over ethernet is 990meg symmetrical, so interferance isnt an issue it feels like the transmission is weaker than it says but I tried to somewhat rule that out by going as close as to the device and this offered no changes.

The transmission rate maximum under some configurations seems to only be 24dsBm 251mw now too, this seems to me to be a common sense reason why the peed is slower but I’m not a software guy

I have ruled out the computer by connecting my old router, I get the expected 750-800 symetrical bandwith over WIFI, and on ethernet I get 990 symmetrical, So somewhere along the lines here in the last two months my speed has dropped to the point I noticed the other day, now this is a problem as the Transmission rate (as its displayed in luci) is 1200, this should be more than enough to give 700 Meg at least, and I wont settle for any less than that, at the moment my other router is faster than this although the TX rate says otherwise while connected, this is clearly a maximum that not being saturated as all other substantiating factors are constants.

I purchased this router for its speed and versatility, but the speed is now lacking, if we could have this fixed it would be much appreciated.

Yep firmware issue with 4.x
For now ill be reverting to 3.x and wait until this is fixed.
Also would be nice to report this somewhere as official issue on 4.X and not a forum post.

subzero06 · 2022-12-01T02:57:54.641Z

I received a replacement router (same flint) from amazon
This time i upgrade to version 4.x using “uboot” from this guide:

docs.gl-inet.com

Debrick via Uboot - GL.iNet Docs

Documentation for GL.iNet Productions

For some reason the router was flashing blue for like 1 hour and wouldn’t stop - so i just unplugged and plugged it back in to see if it actually upgrade…and it did.

This time, my wifi is back to normal speeds! im guessing the best way to upgrade from 3.x to 4.x is with Uboot and not via the control panel.

check my wifi speed now: (this is is latest firmware 4.x)

Thanks for the report.

So your issue is fixed with a new product.
But we still think the problem is the firmware and are investigating more.
