Hi new to the forum as my SXT R11e-LTE has performed perfectly for over two years without missing a beat.
I really hope someone will be able to help with my query. apologies if i have posted in the wrong channel.
Today it suddenly will not receive any 4G signal, even when scanning it will not list any 4G networks from any providers.
However, if I disable LTE it will receive and connect to a 3G signal from my provider EE.
Upgraded to latest firmware
put EE sim card in mobile phone - connects to 4G at the location no problem
enabled all potential EE channels (previously was set to channel 3 only)
added O2 sim to SXT, only connects to 3G network on O2
Taken apart to inspect for water / insect damage - nothing of note.
is it possible that there is a problem with the LTE card that allows it to continue working on 3G but no longer on 4G? Has anyone experienced this before?
