BE550 firmware 1.2.2 fail
Warning — the new firmware may break your internet access.
Saw there was a new update in the web UI — 1.2.2 Build 20251209 rel.57736(5553). Tried it twice, both times it broke my internet access. Seemed to break SSL connections in general, so almost nothing would connect. Had to revert to the 1.2.1 firmware available on the support page to fix. Strangely, the 1.2.2 update isn't listed on that page at all.
Running on gig fiber directly connected to the ONT, with an RE635BE extender using ethernet backhaul, with EasyMesh.
