Significant issues with GL-B3000

Technical Support for Routers

Hi!

I bought a GL-B3000 router about two weeks ago and I've had some notable issues with it. The router is running firmware version v4.5.19.

  • Samsung Smart TV (Tizen): When configuring the same SSID for 2.4g and 5g networks, the TV fails to acquire a DHCP lease. When using distinct SSIDs, there is no problem. With a previous router (RT-AC66U) this worked without an issue.
  • All Smart TVs in our household: Wi-Fi connectivity drops randomly, and streaming services stop working and requires a reboot of the TV. The router's logs show no interesting data regarding this. This behavior was not happening with the older router (RT-AC66U).
  • If Adguard Home is enabled, the router completely freezes on random occasions. Is this because the router's hardware is too weak to run AGH?

Current setup:

  • Distinct SSIDs for 2.4GHz and 5GHz bands, to migitate the Smart TV connection issue.
  • Disabled Adguard Home to migitate the freezing issue.

Any idea which might be causing these issues? Would it be worthwhile to open the advanced UI and tweak settings right from there?

I find that the 4.7.2 beta is better than the 4.5.19 release

I think like you. In general 4.7.2 works better than 4.5.19.

I have the same issue. When I turn on AdGuard, Marble freezes and I need to reboot and quickly unable AdGuard.

Which firmware version are you on

4.7.2

With firmware 4.7.2, the issue still persists. A new symptom is that the whole device stopped working and had to be rebooted. Adguard Home was not enabled. I'm very close into requesting a refund and switching to another router. This behavior is unacceptable.

Hello,

Truly sorry about this issue.

Please PM me the issue syslog "logread.tar" file, I'd like to check wireless connection, if possible and the device did not return. Thank you.

About the ADG issue, ADG may have taken up too many resources, and cannot run too many rules, the Marble RAM storage is not very large, it will easily lead to the Marble system crashing due to the ADG occupies too much memory resources and insufficient memory.

Please try the following workaround, to limit the ADG resources occupy:

Add the procd_set_param env GOMEMLIMIT=100MiB GOGC=40 , on this configuration /etc/init.d/adguardhome.

Hello Bruce and thank you for the assistance. Next time the issue occurs I will PM the syslog for you. Apparently the logs don't survive reboots.

The thing is that the Wi-Fi keeps up, but the Wi-Fi connection does not transmit data in or out.

The high probability is that ADG has a lot of DNS filter rules, and there are too many system resources called, which leads to oom and kernel operation is unstable.

You can try the above workaround, hoping to improve it.

The router has crashed 5-6 times even after disabling AGH. I'm now sending the crash log to you Bruce.

Edit: Apparently I can't see the option to send a PM.

Post it here,
I find it strange that the x2000 and b3000 don't have a unified firmware between them.
