Hi,
on a RUT955 used with italian cellular provider vodafone I'm experiencing problems.
Specifically, router does not connect to cellular network, even though I have strong signal (-51 dBm).
On system log I have the following (just relevant parts):
Wed Apr 6 09:10:53 2022 local1.info gsmd[2270]: gsmd send: 'AT+QCSQ' (8)

This odd behavior occours only on this router.
On an identical (same model, same fw) router with the same provider (Vodafone IT) in another site everything works.
Any hint?
Since I'll probably have to interact with Vodafone IT, any suggestion on where to look at, so I'll tell them in an attempt to restrict problem area?
Thanks
Ciao
Andrea
