So…
Omnia from Indiegogo. No internet for any of devices on the network, but connection test in reForis is fully OK, including test in DNS section.
Update went on 26 november according to snapshots page (no notifications about that in reForis) and today 29. november, no internet. I have tried to change DNS provider and turn on/off DNSSEC, but nothing helped. Only rollback to 7.03 helped.
Very strange. Please fix it.
