Mt76x02u_mcu_wait_resp failed with -110

Installing and Using OpenWrt

My AP is visible but my phone won't connect to it anymore.

The system log from Luci (where is that log from the command line) says:

Mon Mar 16 04:44:46 2020 kern.err kernel: [27111.830848] mt76x2u 2-1:1.0: error: mt76x02u_mcu_wait_resp failed with -110

I've already got

option disassoc_low_ack '0'

set.

I rebooted:

[    8.631755] mt76x2u 2-1:1.0: firmware upload failed: -110
[   10.195524] mt76x2u: probe of 2-1:1.0 failed with error -5

Do I have a hardware error?

What hardware is this?

What version (actual build) of OpenWRT?

There has been a lot of work on MT76 lately, so you might try a snapshot and see if the problem is gone. I've been running the snapshot from 2020-03-12 with great success.

Raspberry Pi 4.
OpenWrt SNAPSHOT r12553-3666c67a54 / LuCI Master git-20.072.24013-4b90e67
The AP has stayed up a day. :slight_smile:

The AP went down again overnight.

It doesn't work after I rebooted.

This seems old.

I tried to update my packages:

MediaTek MT76x2/MT7603 wireless driver (metapackage)

    The installed version of package kernel is not compatible, require 5.4.24-1-06ea4400… while 4.19.108-1-24e1d7b0… is installed.

I installed my own snapshot that includes more packages and is kernel-5.4.24.

My AP went down again last night and it won't accept connections. :frowning:
