Update on that issue:
- I have check ID of devices that cannot connect to internet, all are 192.168.0.xxx while it should be 192.168.1.xxx. I try to change it manually but the manual ID does not work
Hi @Ntl9630 Welcome to the community!
Can you try to change the settings on the devices that can't connect to the network to "obtain IP address automatically" or "enable DHCP" on those devices, also ensure that mobile hotspot or tethering is off on those devices.
What type of devices are you having trouble with? If you can provide more detail it would be helpful, example: iPhone or Android phone or Windows PC on Windows 7/8.1/10 etc.
Hi @Ntl9630 You need to find the device that's distributing the 192.168.0.XXX addresses, it seems you have 2 DHCP servers on the network, is your previous router totally disconnected and powered off?
