During the day, my premier connection flies (29.5mbps/3.5mbps) -- but a few weeks ago, evenings have been (relatively) abysmal, with downstream speeds topping out around 5mbps. Nothing has changed on my end, using a Docsis 3.0 Motorola SBG6580 in bridge mode with a D-link DIR-865L. Bonding at 8x2. I've tried on multiple devices, rebooting router and modem, bypassing router, etc.
I do live near a university (I'm in Irvine, 92612), so I wonder if students returning has had any effect (though this wasn't a problem all through last year).
I was told by the installing tech that my ancient house's internal wiring is not quite up to snuff (not sure what I can do about that), and that's led to some intermittent cable-TV issues (blocking, no signal for some channels), but it's largely been okay.
Not sure where to turn to for help, as I don't want to go through the phone-support run-around (might have to though).
Any ideas would be appreciated... :)
