first some explanation about my config.
Modem ISP ↔ AR750S-ext (3.104 with adguardhome) ↔ LAN
AR750 is static ip 192.168.1.2
is configured in DMZ
is openvpn PIA for some clients.
is Adguardhome with cloudfare DoH
I have tested USB tethering/hotspot on a testbench and it worked great. That is, without a WAN cable attached.
Today i had ISP troubles. Modem would not connect to internet. I connected hotspot to ar750 but no internet on router.
Then USB tethering, and no internet.
Disconnected wan cable and changed port to lan, same, no internet.
That’s why I bought the ar750s initially to switch fast from WAN to USB tethering or mobile hotspot.
Errors like :
Error: control/version.json | Couldn’t get version check json from https://static.adguard.com/adguardhome/release/version.json: *url.Error Get https://static.adguard.com/adguardhome/release/version.json: synthetic.wrap: all upstreams failed to exchange request, cause: read udp 192.168.42.43:38201->184.108.40.206:53: i/o timeout (hidden: read udp 192.168.42.43:43549->220.127.116.11:53: i/o timeout, dial udp [2620:fe::10]:53: connect: permission denied, dial udp [2620:fe::fe:10]:53: connect: permission denied) | 502
Can somebody help me how to switch fast from wan to usb tethering/mobile hotspot?
Thank you very much,
