My contract EE unlimited data SIM suddenly stopped working in my RUT955 about a week ago. Had been fine for over 1 year. I initially thought it was an EE issue so they sent me a replacement sim. New sim also does not work with the overview screen in WEBUI saying "Disconnected". I have tried loads of different settings; Auto APN, manual APN with no luck. Lastly I upgraded the FW to 00.06.07.1. Prior to this it was on a 2019 version (06.04 I believe). Please help!
