5268AC DSL modem Broadband 2 now flashing red when using surge protector...has something changed?
I understand the surge protector isn't an absolute necessity, but I figured for a few bucks (and since the Tel In/Out comes bundled anyway on many devices), it might be worth it to add a little extra protection.
Since maybe August 2017 I've been using a Belkin CSP100TW single-pole plus Tel device to protect my DSL line. About two months ago, all of a sudden, the Broadband 2 light started flashing red. The internet connection still worked fine. General seat-of-the-pants feel was that everything was normal. I just used the Ookla speedtest and got 40ms ping, 48Mpbs down and 11.7 Mpbs down (I have the 50Mbps plan).
I've rebooted the modem multiple times and the behavior is the same. I can plug-in directly to the wall jack and it works fine with all Broadband/Service lights solid. But I tried the Belkin and also an APC P8VT3 device, and I can't get either to work without the red flashing Broadband 2 light.
Did something change somewhere to cause this issue? Any ideas as to what is happening?
