I absolutely desperately need to solve this issue, so I’m going to try this again now that I’ve narrowed down my problem a bit.
RBM11G + Quectel RM502Q-AE + Tmobile
This modem was working since December, but stopped working a few weeks ago. After it stopped working, I could still ping IP’s from PC, but not addresses. I could ping both in winbox. I’ve since tweaked my configuration and can now ping both from my PC, but I still have no internet. This isn’t isolated to my PC, but my asus router and all devices. Winbox even times out when searching for updates, so I assume the modem itself lacks the internet as well.
My configuration tweak was removing the DNS servers I had originally set, 8.8.8.8/8.8.4.4. Another tweak that was recommended was setting the DNS to 192.168.88.1 and turning “allow remote requests” on.
Configuration:
EDIT: Sorry, I wasn’t aware export didn’t do the full configuration. Here’s the full export verbose configuration.
