GL-AR300M becomes slow/unresponsive, needs reboot

alzhao · 2022-06-01T04:21:27.267Z

As I understand, you only set up repeater and then after some time, the router is not responsive.

Can you do this:

Before the router is not responsive (you have to make a guess), ssh to the router and get some log and other data.

dmesg
logread
ps
top

eric: Those are the first real logs after it rebooted, aside from a few of these sporadically

daemon.notice wpa_supplicant[2536]: wlan-sta: CTRL-EVENT-BEACON-LOSS
daemon.warn dnsmasq[2381]: possible DNS-rebind attack detected:

ZBeeblebrox · 2022-06-01T06:07:29.909Z

The most recent outage latest about 1 hour and 20 minutes, starting at about 04:30 and ending at about 05:50. I have attached the output of the commands from just after recovery (too large to include inline).

GL.iNet after recovery 2.zip (8.5 KB)

alzhao: I will try to get data from just before it is unresponsive, but it can go for hours without issue, so it is very hard. Maybe I will try to write a script to query it repeatedly.

alzhao · 2022-06-01T07:26:06.065Z

Can you turn off DNS rebind protection?

This is usually required when you connect to network with captive portal.

ZBeeblebrox · 2022-06-01T18:19:09.816Z

I have switched off DNS rebind protection. It failed again. I am running top and ps every 5 seconds. Here are the last results before it became unresponsive.

eric · 2022-06-02T00:47:10.964Z

I have looked at the zip file and nothing is standing out to me. Maybe @alzhao will see something.

alzhao · 2022-06-02T01:47:47.757Z

Can you turn the “Real time data statistics” off? It is in Client section.

ZBeeblebrox · 2022-06-02T03:13:29.217Z

Real time data statistics was already off.

alzhao · 2022-06-02T08:29:13.777Z

The log does not show anything special.
I am trying to replicate this problem in my side.

Here is a check list. Pls help to verify that you are using the same.

AR300M with 3.212 firmware
no openvpn, no wireguard
no mac clone
Just repeater to an open wifi network
DNS rebind protection is turned off
Client data statistics is turned off
The web panel is not activated in your browser all the time. Turn it off when not use.

If the above all matches, can you please check if any of your clients may make trouble? You can disconnect one of them to see if things improve.

ZBeeblebrox · 2022-06-02T17:02:57.417Z

AR300M with 3.212 firmware

I have been keeping it open. I will not do so any more.

I will try disconnecting some of my devices.

Maybe this is the problem. Pls try and let me know.

ZBeeblebrox · 2022-06-03T05:45:46.181Z

I have closed all of the web panels, however the problem occurred again.

alzhao · 2022-06-06T09:02:13.327Z

Sorry I have no more clue.

Walliot · 2023-03-14T14:25:31.390Z

I am experiencing the same issue. In my case, the router (AR300m16-ext) becomes unresponsive after about 3 days. It doesn’t matter if it has wireguard vpn turned on or not. My router has also stopped responding while in AP mode (not repeater).
One interesting thing is that the middle green LED light blinks sporadically and randomly when it is hung up and the amber wifi light turns solid. I noticed the middle green light begins to randomly blink a few hours before the router becomes unresponsive.
While the router is unresponsive, if I disconnect a client from the wifi signal, it is not able to reconnect until I restart the router by unplugging and plugging back in.

Walliot · 2023-03-14T14:28:10.335Z

I own multiple AR150-ext white mini routers and they have never given me any problems after months at a time working as repeater or AP mode. I might go back to using my older stable AR150-ext routers if this issue persists with the AR300m16-ext.
*note: all routers are updated and running latest firmware available.

alzhao · 2023-03-15T05:12:42.057Z

You mean in AP mode this problem happens? not in router mode, right?

AR300M an AR150 all use ath9k wifi so the behavior should be pretty the same. AR300M takes much more power than AR150 so need to use a better power adapter.

Walliot · 2023-03-28T02:28:07.696Z

Hi Alzhao, my 300M16-ext has done this in both AP mode and in Repeater mode. I bought a dual-boot NAND used AR300M-ext on ebay a few weeks ago. It’s been working flawlessly for over 9 days so far without hanging up. Im using the NAND flash at the moment. Same power supply I was using when the 300M16-ext became unresponsive. I think it must be a hardware issue with my specific 300M16-ext.

alzhao · 2023-03-28T09:18:38.698Z

Walliot:

If you use the same firmware version, AR300M16 should perform the same as your old AR300M. Otherwise there may be issue.

Sirius · 2023-04-29T13:39:38.574Z

I have the same problem with mine. I am thinking maybe it’s a power issue as I plug the mobile wifi modem into the USB port. It isn’t so critical for me as long as I can get it to reboot whenever the ping gets too slow (when I switch it off and on again the internet speed also gets 10 times faster). Is there some way to make it restart automatically when the ping is slow as this is always one of the symptoms, not only the slower internet?

EDIT: This came up straightaway in a search so is something like this possible? ICMP Check (Ping Reboot)

Walliot · 2023-06-07T21:28:28.863Z

Have you found a fix rather than rebooting it? Rebooting it a band aid and not a true fix.
