MR6400 4G router internet connection stops but still connected
This might be a DNS problem or even my ISP, I don't know, but I'm getting connection time-outs when loading web pages.
I run the MR6400 as a simple modem, no DHCP nor WiFi. I run DHCP on a seperate router and have my own DNS server (Pi-Hole) There's no 'bridge' nor is there a DMZ - the MR6400 simply sits in the network at 192.168.1.1 and the DHCP router behind it on 192.168.1.2. Periodically, I get these time-outs. Everything on the network loses internet connectivity BUT the MR6400 is still connected, showing a good signal strength, albeit with no apparant data transfer going on. The only thing that resolves this is rebooting the MR6400 (neither rebooting the DHCP nor the DNS fixes it) I have to do this several times a day.
I've used the MR6400 in a different set-up with a different ISP and had no problems. Any pointers as to what might be going wrong would be appreciated.
