[Signals] Could a dodgy surge protector affect SNR ?

Click for full size
Undoubtedly this is a weird/stupid question but ... could a dodgy/malfunctioning-ish surge protector cause signal problems especially SNR ?

For about the past 5 weeks, my Arris 760a modem's downstream SNR has been in the 34.xx range (formerly 37.xx) which I attributed to arctic temps but it's considerably warmer now. Just discovered some moisture got in to one of the plugs on my surge protector which appears to be from a while ago :-(. My Vonage VDV-21 adapter feels quite hot on the bottom.

I live in a nice but 1960s home with only 2 electrical outlets per room so without a surge protector, I can't plug everything into one outlet, lol.

Also - my leased modem is DOCSIS 3. Is the upstream channel type listed as Docsis 2 correct ??

Thanks muchly.

Well, there have also been cases where using the coax/RF surge protector in some combination AC/telephone/RF surge protection devices has caused signal noise/level problems (e.g., »Re: [Firmware] SB6141 Download Speed Issue ), but I had not heard about that happening from just plugging into it.

Yes, both DOCSIS 2 and 3 modems can use 64QAM ATDMA upstream carriers, so that's why they show as "DOCSIS 2" type.

Mine is a Belkin with (supposedly) a telephone plug gizmo. I looked at the link you provided; any chance you could recommend an appropriate surge protector, please ?

I use mostly APC UPSes, but you can go with an inexpensive APC or Tripp Lite surge-protecting power strip like these:

APC Essential SurgeArrest, 7 outlet

To answer your question, remove the surge protector and just get a power strip and plug everything into it. Now do you see a change????
