Whole network IP address changes after power outage
I am having issues with my Deco M9 Plus mesh network changing the default LAN IP range after power failure.
I have seen several other locked posts with this issue, but the resolutions do not work for me.
I have VM (UK) Hub 3.0 set to modem mode. There are no DNS or WAN settings available in this mode.
My LAN IP is 192.168.1.1 and DHCP range set to 192.168.1.2-192.168.1.254
If the power fails or trips, the IP range can sometimes change to 192.168.0.1/254.
This breaks everything in my house! And even worse, the main Deco cannot get internet from the modem anymore! So I cannot fix remotely and it takes absolutely ages to get everything back online.
IPv4 settings are;
Dynamic IP
IP Address: 82.**.**.***
Subnet 255.255.255.0
Default gateway 82.**.**.1
Primary DNS 192.168.4.100
Secondary DNS 192.168.8.100
I have tested this over and over and over.
When the power fails on the modem and Deco (or I pull it), when power returns, the IP will change on the 1st, 2nd or 3rd test without fail!
Once the Deco has been reset to correct IP; If I pull the power and reboot the devices one at a time (modem first then Deco) the IP remains correct.
That is NOT a fix though as if the power fails when I am away, the system does not work and everyrthing is down! And if it fails and resumes when both devices connected I have to go through the rigmoral or resetting the Deco without internet access. Not fun.
TP-LINK! Please help! Thank you!!
