T3 t4 errors for 3 months!!!

[Polajenko]

I’ve been working with Comcast for three months with no resolution to my frequent drops of Internet. I work from home because of Covid and I need reliable Internet.

I am using a Netgear CM 700 modem with no splitter. I’ve had 2 technicians out here and they say there is noise in my neighborhood but there is no resolution yet.

If you’ve been working with Comcast, have they had maintenance out to track down the noise. That’s how it gets fixed

[Polajenko]

Yes and they admit there’s a problem in my neighborhood yet nothing gets fixed. Point of contact does not answer my texts anymore.
