Not getting upload speeds

Good afternoon, 

I recently upgraded my cable modem speeds from 1. 2 GB to the multi-gig 2 GB.  I was only getting around 40 MB uploads before and was expecting to get at least 150 to 200 Mbps based upon the advertised speeds of up to 300mps

I have seen in other forum posts where you have had to reprovision the modem. I was wondering if this could be done to fix mine

Are you using a gateway device rented from Comcast or your own purchased modem ? Make and model number ?

Did you ever get a confirmation E-mail stating that your local area was ready ? Sometimes the cart gets put before the horse.

I have also recently upgraded to the 2gbps package and was told I'd get 350 up. I'm averaging around 240-250, which is great, but it will randomly drop to around 2mbps, making any stream drop frames like crazy. Not sure if this is happening to you as well, but wanted to add this since we have both upgraded recently and I'm also having bad uploads, albeit intermittently

I am working with support, they have to send out a Tech.  Signals seem low to them.

OK. Good luck with the visit, but that still doesn't answer the question ?

I just upgraded my modem/router to an Arris G36 on Xfinity's recommendation to take advantage of my "new and improved" speeds and service. My download speed was supposed to go up to 1.2Gbps and my upload to 300 Mbps (had been around 40). The download speed's highest return was in the 900 range, which was ok. The upload speeds actually exceeded 300....around 350. After five days the speeds suddenly diminished. My download speeds dropped back to around 500 and upload speeds to about 110. This is very upsetting. I work from home and send large files daily to our agency server. Upload speed is critical to my job. Xfinity says the problem is the modem. Arris says the problem is not the modem. I've done every re-start, re-set, and test both Arris and Xfinity said do, and nothing has changed.

Personally, I don't believe Xfinity if they say the sky is blue and grass is green. The speeds were excellent for five days and then the performance plummeted with no change of anything on my end.There are internal modem settings that Xfinity can control that we cannot change, and I'm certain that they have arbitrarily and deliberately diminished the performance of this modem to push me to rent their Gateway for $15 a month.

I can't be the only person having issues like this. The cable companies, and particularly Comcast/Xfinity have gotten away with [Edited: Language] like this for years.
