Anyone else have a TP-Link Archer C5 (AC1200) router that
permanently loses it's connection the moment you unplug
either it or the cable modem (for example, to move it)
or whenever the Internet goes down and comes back up.

Basically, if you interrupt power to the router, it can't
re-establish a connection with the Comcast cable modem.

When I call customer support for Comcast, they tell me
the Internet is working fine (and plugging the computer
into the modem confirms this). Comcast doesn't care what
mac address is downstream of it, so, there should be
absolutely no need for any mac cloning whatsoever.

When I call customer support for the router, they had me
connect the computer to the router and then press the
mac clone button.

On then, after cloning something, does the router work again.

I'm confused what is going on.

TP-Link support barely speaks English so I'm just asking if
you have the same problem and if you can explain what is
really going on.

TIA
