Slow Speeds: Paying for 175mbps, getting around 30mbps

[linkgirl09]

my xfinity internet is very slow compared to what i'm paying for.    the Tech came out to our apartment and checked the outside wiring up to our apartment,    ran a temp line to our modem and still got the slow speeds,   said it was most likely my modem.    was using a personal one ( ARRIS SB6190 ).  Went and bought a new Netgear CM600.  still having the same issue.         Noticed the apartment building behind mine, has a RG11 ran above ground from Building 7 to Building 8 to the connection boxes for the units.    could the underground cabling ran to my building not be working correctly........ have already chatted multiple times.   and had a tech come out.  Need to resolve this issue.   i'm not happy paying for 175 and getting 30

Same exact situation here - paying for 175 and getting 30, except in a house not an apt.

same here paying for 600 getting 90 - two techs said equipment fine its a line problem but no one can tell me when they will fix it

Same. I had 200Mbps service installed a couple of weeks ago. I average about 10-20Mbps. Very disappointing.

Drop your payments for the internet-tier/service portion of your bill to the minimum which is probably $49.99 or $59.99 per month - check your rate card.    Give comcast rep time to arrange credits for you - they will probably be happy to credit your ENTIRE monthly bill for every month the problem exists and appears to be within their ownership.     If they cannot get it done, you can do it yourself via your credit-card/bank.    Dispute every monthly charge for any internet "speed" above the "speed"  which you are actually measuring, then pay $0.00 monthly until they bill you exactly correctly or otherwise identify the problem as being on your end.   Pro-rate your service-level savings from the day you first reported the problem.   Also It can be helpful to rent the xfinity modem pro-rated just for a few days, it will cost about $1 to do that - and you can use it demonstrate the issue as close as possible wired to the demarc cable, to prove the problem root-cause is 100% in comcast ownership area.
