Question about signal boosters/amplifiers

I live more than 100' from the street.  Signal quality has been a problem for years.  I'm supposed to have 1.2gigs for internet speed.  I can't get over 900.   Picture pixilation is also a problem..   I have had several signal amplifiers put on my on cable.   I want to try my own amplifier.    Anyone know of an amplifier more powerful then the ones Comcast uses that I can try?

Using a 'more powerful' amplifier, even if you find a compatible one, is unlikely to give you any better performance.  Have you had anyone come out an inspect your cabling from the street to your hardware?  It may be that there is a problem with the physical wires that a trained tech can spot.  It would have to include a visual inspection in addition to the measuring of impedance, line levels, noise, etc.  You should schedule a visit and show the tech the problems you are having.  Good luck!

Hello @nolan62! Thanks for taking the time to reach out to us here on the Xfinity Forums for support.

 

Much like @NoNoBadPuppy mentioned, using a different amp is unlikely to help much as it only extends the signal you already have. If your source signal isn't optimal, we will want to start there. :)

 

When you are testing your speeds, are you doing so over a wifi connection or hardlined directly to your gateway via ethernet?

 

I no longer work for Comcast.

I test with a hardline, directly connected.

How long ago did the last technician run a new line and install a new amplifier? Was it fairly recent? Did your speeds improve temporarily and then return to where they are now, or did it have no effect?
