Slow and droping wifi 2.4ghz

[zauzaupt]

Hello everyone

Need some guidance, i have a main router rt-be88u with 2x xt8, ax86u and ax55u nodes, in aimesh setup.

like the title says, my wifi on 2.4 band is very slow and make all my devices keeps droping conections.
i have one camera at 50cm from an xt8 device and even this one is slow and lags
on the 5ghz band all works very good.
i already reset all devices, reconfigured them, all with last firmwares from asus, and same result.
all is wired, except the ax55.

this is getting me crazy since i have a lot of cameras and iot devices that operates on the 2.4ghz.
i live an isolated house, so i dont have any other neighbours that can cause interference.

any advice that i can make to improve this?

Try setting 2.4Ghz "Channel Bandwith" to 20Mhz.

Try setting 2.4Ghz "Channel Bandwith" to 20Mhz.

yes, already did, and stick the channel also to 1 and 6, same result.

In that case, your problem is likely firmware-version related. Install official Asuswrt on all nodes, Merlin on the main router IF you need it. As for myself, the last stable Merlin-firmware for my AX86s main in my Aimesh network was 388.7. 388.8 gave me instability, and I'm awaiting feedback with respect to the new 388.9.

all my firmwares are stock asus and the last ones.
i think this strated to happen when i swap my ax86u as main router with the be88u

did you recreate the Aimesh from scratch when you changed the host router or did you just swap and reboot ?

AiMesh works best on same hardware and firmware versions. Anything else may work, but is an experiment.

At least start with the firmware on each being the same version number, even if you have to downgrade. AND configure the settings by hand. Don't load a saved config.

Did all from scratch.

I'd start by trying to roll back the fw version on the main router, as that's the most likely culprint if you experience issues on all nodes in the network.

You have to recreate it from scratch when changing the host router, as there is no way to transfer a functioning Aimesh setup. The question if whether he did a hard reset on the routers before pairing them with the new router, but as the pairing went well, I don't think that's what is causing the issue.

i think this strated to happen when i swap my ax86u as main router with the be88u

And there were no firmware updates on the nodes during this swap? That strenghtens my suspicion that the issues are related to the main node, and experimenting with firmware rollback is the path of least resistance.

i updated the be88 to the last firmware and reset all nodes.
it gets to the point that even router show device as conected i cannot even ping them until i reboot the nodes

Do you have a spectrum scan like from WiFi Analyzer or other?

 

[degrub]

Are all of the firmware the same dot release ?
Not necessarily the latest.

Return the WIFI 7 router and go back to all AX. WIFI 6. You will have fewer issues.

If you are on 3006 codebase, try reverting to 3004.

TOTALLY AGREE! My RT-BE96U has been more of a headache than a joy. It was a "let's play around since I have a couple WIFI7 devices that turned into a nightmare. My RT-AX88U network was pretty rock solid (non-PRO 3004 FW).
