X50 Deco's no internet after firmware 1.5.5 update
My three x50 Deco's were working fine until last night when the firmware auto-updated to v1.5.5.
Now, there is no internet connectivity through the Decos, either via Wi-Fi or wired.
All three Decos are glowing green, and the app tells me, 'Everything looks good.' They show they are connected to the Internet (with an assigned dynamic IP from my ISP), but none of the devices connected to them can access the Internet. For example, my iPhone connected by Wi-Fi says, 'Connected, but no Internet'.
My ISP modem is online and working fine. If I connect a laptop to it directly, the internet works perfectly.
I have unplugged the Decos and restarted them several times. After restart, there is a brief moment of internet connection for devices, but then it stops.
My configuration is that the ISP modem and main Deco are in the garage. The two other Decos are elsewhere in the house and connected to the main Deco by ethernet cable.
My next step would be to do a factory reset on the Decos, as I read another similar post where that was the solution. However, I would like to avoid that, as I don't want to have to re-program/setup the whole system again.
Any other suggestions from anyone?
Thank you.
