WiFi Problems with GL-X750 V2 EP06-E

limbot · 2022-01-19T05:07:56.320Z

Firmware version currently? Worth updating to latest ?

Thanks for your replies. Here is my input:

When the problem occurs, it’s usually not possible to access the admin page over Wifi. One time I managed it, but it was terribly slow.

I don’t use 5 GHz Wifi, so in my case it only occurs on 2.4 GHz.

Where can I find the System Log and Kernel Log?

My current firmware version is 3.201. I just noticed that there is version 3.203 available. Are there any fixes in the new firmware version, that could be related to my problem?

Thanks and best regards…

I just had the issue again. I was not able to access the admin page via Wifi. Only LAN was working.

I managed to find System Log and Kernel Log. Here are the “newest” entries.

I also sometimes have messages in the Kernel regarding “wlan” entering blocking/disabled/promiscuous mode, so they may or may not be “normal”.

It is likely worth updating the firmware to 3.203, since it was released back in August 2021.

It would be good to test if the problem occurs on 5 GHz band because you indicated that you can fix it by changing the 2.4 GHz channel. The 2.4 GHz band tends to be quite congested and, if 5 GHz does not have the problem, then congestion may a cause. On 2.4 GHz, you should stick to HT20 bandwidth because there is more interference with wider bandwidth.

There are various apps that display all the nearby wifi devices and their channels broadcasting on 2.4 GHz / 5 GHz. I use the Wifi Analyzer app on my Android smartphone to do a site survey and pick the channel on each band to avoid the most congestion.

Did you use Wireguard?

As @limbot said, can you upgrade to 3.211?

sb11 · 2022-01-22T09:33:17.898Z

I already used Wifi Analyzer to pick the best available channel. My channel is not congested and changing the channel is just one possible remedy to fix my problem without rebooting the router. I could change any setting on the Wifi settings page - changing the channel was just one example.

No, I’m not using Wireguard.

Version 3.211?? The last available version is 3.203. I upgraded to this version and will further examine, if the problem appears again.

The firmware update did not fix the problem. Yesterday the problem occurred twice again.

Any other ideas, how to fix this?

3.211 beta6 from here GL.iNet download center

sb11 · 2022-01-26T11:56:42.816Z

No, I will not install a beta version.

alzhao · 2022-01-27T11:35:13.520Z

Beta may not be good. But it is released today as stable version.

sb11 · 2022-02-01T08:36:15.727Z

I upgraded to 3.211 but the problem still occurs. This is getting really annoying.

Are you sure it is wifi problem, not LTE?

If you test 5G wifi and Ethernet cable and it works OK, then it should not be a wifi problem.

For LTE, pls try the config in this post North American Carriers, ATT, Verizon, Cricket, T-Mobile Setup and Update 2021

Especially use ttyUSB3 as device to connect which is more compatible.

No, it’s not an LTE problem. If the problem occurs and I run a speed test from the client, which is connected via ethernet, the speed is normal. If I run the speed test from the wifi client, I get a normal downstream, but the upstream is significantly below average. So how is this not a wifi problem?

So when you do speedtest using cable or 5G wifi, speed is normal, right? I didn’t get such info. Maybe I missed something.

For 2.4G, most of the things to try is to change channel. Can you do that? Change between 1, 6, and 11 to find the best channel to use.

As written before, I already used Wifi Analyzer to pick the best available channel.

Wifi Analyzer

I don’t know how does wifi analyzer work. Maybe it is just digital, not analog.

2.4G wifif has interference with some band of the LTE. So change channel to 1 or 11 to see if there is any luck. But as you said 1Mbps seems this is not the issue.

sb11 · 2022-02-14T12:44:14.392Z

No, I don’t think the issue is related to an interference with LTE. Before I bought the GL-X750, I used the same Wifi channel on my old router and never had such issues.

Hello, I've been having this exact same issue as well for quite some time with my GL-X750V2 regardless of what channel I use. Only the 2.4gh wifi is affected and becomes unusable while the 5ghz and LAN connections keep working just fine. I can replicate this whenever I try to send large files to my Synology NAS (connected to the LAN port) from a 2.4ghz wifi client. How can we resolve this? This shouldn't be happening, especially since I'm running the latest firmware for the GL-X750V2. This bug should've been fixed a long time ago.

Please don't reply a 3 year old post.

Open your own thread and provide the details, e.g. do you have USB accessories, what band is your 4G is using and pls give the log when the problem happens.
