AC3100 Wifi disconnects randomly

[JamesH]

I'm a bit a noob when it comes to Networking so bare with me here.

A few weeks back i updated my router with a custom firmware from Merlin 386.2_4

My lan speeds and performance definitely improved and so did my wifi connections.

But since then after a few days my wifi disconnects random devices around the house on the 2.4 networks. Only temporary remedy is to turn off the wifi and back on again or restart the router.

When I flashed the firmware I made sure to factory reset the router because it was advised to do so.

I have around 17 devices on wifi with more than half on the 2.4ghz network. My 5ghz network doesn't seem affected by this issue. Before the cfw i did not have this issue.

Any idea what could be causing this or a suggestion how to fix it?
Any help would well appreciated, thank you.

That is a very similar issue with some RT-AC86U's too:

RT-ac86u kicking devices off after working perfectly for weeks.

Hello gents, I have an RT-ac86u Asus router that I have been loving straight out of the box for the last few weeks. No changes to the default settings except doing the firmware upgrade. As of yesterday 3 devices (ps4, printer, roku tv) just randomly got disconnected from the 2.4 band. Tried...

@Ironic77 did mention in that other thread that he had the same issue with an 88(U) also, which he attributed to high temps.

After being a problem for me for about a week, the problem disappeared. Dunno what caused it or why it stopped being a problem (for now).

These are my current temps i found on the router site. Not sure if its high or not when it comes to routers.

Normal.

A new firmware update was available but the issue is still persisting. Turning off and on the wifi is the only thing that fixes it for a day.

I have two AC3100's in Aimesh setup. I was able to fix my 2.4ghz band by changing to the following settings. I was getting disconnects with the latest firmware 386.2_4 and these settings have been stable for the last few days. Props to L&LD and his guides.

After your firmware upgrade what steps did you perform? Be sure to clear NVRAM and check the initialize box via the gui.

I tried with those settings and also resetting/initializing the box. Not sure where the nvram option is so I just unplugged the router for some time.

The problem still persisting. I think I might just switch everything onto the 5gz untill fix is available.

I'll keep doing more research. Thanks for all tht help
