R2 change IP randomly from 192.168.77.xx to 192.168.0.xx and some devices lost internet

[Bernard]

Hello,

I have a Board Model R2, Firmware Version 3.2.453. (I don't see any upgrade)
It set quite simply with the default Router IP Address 192.168.77.xx

When I connect wifi or wired a device it grab its IP from DHCP (or has Reserved IP set) using 192.168.77.xx

More and more frequently "something happen" and the IP Addresses changes for a 192.168.0.xx
It happens on Wifi and on Wired computers, even those with a Reserved IP.
Then it's a circus.
I have to turn off all the connected device (all I can), sometime to unplug physically the RJ45 (on my MBook Pro) and unplug the modem for 30 seconds.

I suspected 2 repeater I had and removed them but it keeps happening.

Is there something I can do before another reset factory (that's a real pain the setup is not saved !) ?

I guess you have to double check your DHCP settings on the R2, if they are right then make sure your Modem isn't the one causing this IP conflicts. it's your modem in bridge mode? and DHCP is off?

 

In any case just set your repeater static IP on your R2 like 192.168.77.XX and make sure those repearter have DHCP off or they are 192.168.X.1 for their lan to avoid conficlits.

Does the modem/router above the R2 have the LAN IP 192.168.0.x by any chance?

If so, can you let us know the make and model of it so we can look in to it?

Hello and thank you.

From the wall 🤓 I have a Opti Fiber converter Nokia G010G-Q that connect to the R2.
On the R2 I set my PPPOE connection and I get my fixed IP from my provider.
On the NetDuma here my DHCP settings:

I have TP-Link AC 1200 repeater.
It is connected to a switch with a cable and allow wifi in a room far away from the R2.

Is there a way to set any parameter on this device ?

When the IPs change, do they stop getting internet and are you unable to access the R2 interface? You would have to check the repeater manual but unlikely or options would be limited.

Hello Fraser,

I have internet on some devices but not on some.
Hard to be 100% because I have some computer with fixed IP running but it seem that all wifi's devices are not working .
 

[Netduma Fraser]

Are you able to access the interface and see whether the new IP appears on the Device Manager?

[Bernard]

Nope usually I can't get 192.168.77.1 until I unplug and replug

[Netduma Fraser]

Set reserved IPs for devices in LAN Settings and see if they stop changing please

Hello,

I found how to set the RE350 TPlink repeater and set the IP too 192.168.77

I also set any fixed IP address 24h no problems.

OK cool, let us know if you have any further problems!

So, I had a power failure today and everything went back with the usual 192.168.77 ip adresses however my internet was not working as expected.

I could reach station in local.
I could reach google or can.

I couldn't perform a git pull : 

git pull

ssh: Could not resolve hostname gitlab.com: Temporary failure in name resolution

fatal: Could not read from remote repository.

----

 

My PS5 couldn't connect, several website were unreachable.

Several reboots (and pure unplugging from the power lines) didn't help.
I had to unplug the RE350 TPlink repeater and reboot one more time to have things back to normal.

That shouldn't happen and this is a pain.
