GL-XE3000 Puli terrible repeater performance

[brock123]

I started noticing this issue on 4.7.4 firmware, but it's also happening on the 4.8 beta.

On a fresh reboot, the repeater speeds are normal and about 90% of the original network's speed. Then after a few hours to a day, the speed drops to <1mbps. There are also constant dropped connections, and even the admin panel randomly shows timeouts or lack of internet connection.

The logs are full of the following line:

I noticed several older threads have this same issue:

GL-MT3000 / Beryl AX Connection Issues / Intermittent Dropping

Hi, I don't even know how to really describe these weird issues Basically originally(3-4 weeks ago) it just lost the wifi connection and I couldn't connect at all for a while, until it started working again after a few minutes. Now it seems the wifi was still connected to the laptop, but in repeater mode, it was blinking as it lost the (2.4G) to the upstream wifi router. But I was also not even able to connect to the web interface, nor to the ssh. I had to connect a lan cable to get ssh acc…

GL-MT3000 : Extremely slow download after upgrading to firmware 4.6.2

Upgraded my GL-MT3000 (operating in normal router mode) to firmware 4.6.2 and immediately started experiencing severe performance issues. Even navigating the web console (from computer connected via 2.4GHz WiFi) became extremely slow. While trying to navigate the web console/interface to try to configure the router, encountered many instances of the error: Operation timed out. Please check the network environment or reboot the device. Rebooted many times to no avail. Checked the system log …

And more.

My primary use of this router is in repeater mode, so this is a very annoying issue. I would appreciate someone taking a look.

Hi,

Please SSH to the router, and execute the commands:

iwpriv rax0 show MibBucket

logread -f &
while true;do echo ----;iwpriv apclix0 show stainfo;echo ----;iwpriv apclix0 show stacountinfo;echo ----;iwpriv apclix0 show stat;echo ----;iwpriv apclix0 show MibBucket;echo ----;iwpriv apclix0 show mibinfo;echo ----;iwpriv apclix0 show tpinfo=0-2;echo ----;iwpriv apclix0 show vow_info;echo =======;sleep 3;done

When the repeater issue occurs, please copy the issue syslog and share with us.

May I know how do you test the Internet speed of XE3000?

[brock123]

I have saved logs from before, how can I send to you?

Should I run those commands now or after the problem occurs?

I use speedtest, but even loading basic sites like Google is noticeably slow when it happens. And voice calls will keep dropping.

Hello,

you can PM me the syslog through clink the personal icon and message there:

And please help us collect more information:
These commands are running on SSH. When the issue reproduces, please export syslog or copy the content in the SSH window and send it to me.

Is the XE3000 repeater connect to primary WiFi 5G or 2.4G?

If the PC is wired to XE3000, is it normal to access the admin panel and the Internet when this issue reproduced?

[brock123]

I sent you the logs. It depends on the hotel I'm in, but usually 2.4g.

The PC is also connected via wifi. The internet and admin panel remain acessible, but the speed is very slow and the connections often break,

Hi,

R&D have checked the syslogs you sent, there is some wireless 2.4GHz interference in your environment.

1. the channel utilization rate is as high as more than 70%.
2. Check the clients list, all client devices are connected to XE3000 2.4GHz WiFi. If the repeater is connected to primary router 2.4GHz, and the clients are also connected to XE3000 2.4GHz, it will cause the network speed to decline when the wireless interference becomes larger.

There are several tests can help us to verify:

1. Please connect the primary router 5GHz if can and your client devices also try to connect to XE3000 5GHz to see if there is improvement for the network speed.
2. If the hotel does not have 5GHz WiFi, but you can connect your client devices to the XE3000 5GHz WiFi to see if the network speed is stable.
3. When the issue reproduced, if there is a PC/laptop, please connect to XE3000 through wired cable to test whether the network speed of XE3000 is normal.

Hi,

The 2.4ghz network is disabled. All 2 clients are on the 5ghz network.

The most of the hotel only has 2.4ghz though, so the repeater is on 2.4ghz.

[brock123]

Hi, this is still happening at every hotel I go to.

As I said generally the hotel wifi is 2.4ghz and all the clients are 5ghz.

[bruce]

Hello,

When the 2.4GHz repeater issue reproduced, bring the laptop is wired connect to XE3000, how about the speedtest.net result is low?

I assume that environment 2.4GHz channel is too crowded, which causes the repeater bandwidth to obtain unsatisfactory.

You can do a comparison test, like the XE3000 repeater is connected to the phone hotspot (5GHz) or other primary 5GHz WiFi, and do a speedtest, which can indirectly sense the interference of the 2.4GHz WiFi on that environment.

Hello Bruce,

I don't have an ethernet port so I can't test that directly. I did however run iperf 3 directly from the router to test without the client (iperf3 -c iperf.he.net -4 -R -p 5201 -t 20). Also note this happens almost daily across multiple hotels in multiple countries and is immediately fixed by a reboot, so I do not think it is a crowding issue. Here's my test results:

Problem started:

(ran multiple times, tried various things like disconnect and reconnect client)

iperf3 result:

Immediately after REBOOT:

This pretty much happens daily.
