MV1000 - Dropping internet connection randomly

Technical Support for Routers
1

Hey Everyone, my Brume seems to be dropping internet connection. The logs show my interfaces as going down. I have vlans enabled, working fine for months.
I tried swapping my smart switch, but same issue. I dont know what else to look at.
I thought maybe my VPN provider, so I disabled the VPN service on my Brume, but no luck.
I’m on version: 3.203

I do have luci-app-wrtbwmon installed along with brvphoenix/wrtbwmon installed. I also have IPTMON installed.

Can someone assist? I can’t seem to figure this out. My network hasn’t changed for months. Same cable, switch, setup, etc.

My last resort is to reset the Brume, but I have it setup perfectly. I’d hate to reset it and lose my configs.

4

Can you tell me how the Vlan configuration works? So that it corresponds to the analysis.
I don’t have VLAN on, encrypted DNS + ad filtering, and the network is open.

5

Have you tried using a new Ethernet cable and/or switching from LAN0 to LAN1?

I do not work for and I am not directly associated with GL.iNet

6

I did swap out the switch for another smart switch. I will try the cable tomorrow. The cable is fairly new, under 1 year old.

7

Just a base vlan setup, I followed it from hansome. :slight_smile:

8

Did you also try both of the Ethernet LAN ports on the router?

I do not work for and I am not directly associated with GL.iNet

9

I did not as I have vlans tied to lan1. But the problem seems to have gone away with no action. Werid. I will monitor the device a little more.
