No internet from router

Installing and Using OpenWrt
1

Hi, so I’m pulling my hair out on this one…

I have a modem (zyxel EX5601-T1) in router mode:

Ip 192.168.1.1, mask 255.255.255.0
I have a static dhcp lease for my router (openwrt) behind it: 192.168.1.2

Router is a Netgear r7500 v1

When connecting my laptop to the modem everything works as expected.

When connecting my laptop to the router, internet works for a minute or two and then shuts down.

I have a freshly installed openwrt 24.10.0, only changed lan ip to 192.168.2.1.

Will post some configuration shortly.

Connect how?

Where?

I connect my router to one of the lan ports of the modem, wan port on the router.
I changed lan ip to 192.168.2.1 in LuCi - Network - Interfaces - lan

6

When I restart the wan interface it only broadcasts DHCP, but never receives anything:

When doing /etc/init.d/network restart it works again. For a few minutes.

Does this occur without the static lease you created in the upstream router?

Can we see the logs after this?

There's nothing that seems apparent as a cause - are you undertaking any other steps after that?

8

Are you by any chance connecting the R7500 to the EXs LAN side 2.5GbE port ?

These are the logs after /etc/init.d/network restart:

I'm not undertaking any steps after that. I just start a www.speedtest.net and watch internet go down again.

No, the router is on modem LAN port 2 right now. I had it in port 1 (2.5GbE) before I upgraded openwrt, no problems. Also, when I now connect the router to port 1 it shows the same behavior.

I meant logs of a failure. Apologies if that wasn't clear.

I can't tell if the link messages are related to your restart or not.

This occurs after high throughput?

Lastly, you can use 1 post to respond to mutiple people.

It seems to be 24.10.1 and 24.10.0 not working properly on my router. I downgraded to 23.05.5 and internet is stable now :slight_smile:

Which one of them?

I have T-56 in the lab, no issues whatsoever, except for the LAN 2.5GbE port going up and down if connected to a 1GbE device.
