TL-MR6400: LTE connected but no internet
Hello team,
my TL-MR6400 is providing a Wifi signal and is connected with a SIM card over LTE, but there is no internet connection.
I followed this troubleshooting guide (https://www.tp-link.com/de/support/faq/2842/) but it didn't solve my problem. Could you please assist?
My troubleshooting
The IP address is not 0.0.0.0, which means I'm connected with my carrier:
Unstable 3G/4G network? I inserted my SIM card in my phone in the same place and it is working fine, so no.
DNS problem?
I changed the DNS server to 1.1.1. and 8.8.8.8 and this didn't help. But when I check on the option page status it still states a different IP for DNS server (see first screenshot). Maybe this is the issue?
Further testing
I tried to ping and trace different IPs and hosts but none is working. So definitely not just a slow connection but no connection.
Any help is highly appreciated! Thanking you in advance!
