Re: Comcast blast not getting full speed

Need help my wifi keeps disconnecting g since I upgraded to blast and got the xfinity modem which includes phone. My speed tests are as follows:
Http://stage.resutls.speedtest.comcast.net/result/648644764.png. This was for the wired through Boston server. The New Jersey wired test is under 648648084.png. The wireless out of Boston is 648696584.png. And the New Jersey wireless is 648699044.png. Tired of having to deal with this every night when my son is gaming with friends. Can I book my old wireless router into the xfinity one so that it will work like it used to or is there other solutions.

Re: Comcast blast not getting full speed

How is the signal level and noise in your modem?

Can you access to http://192.168.100.1 and post a print screen of the modem signal?

Re: Comcast blast not getting full speed

The upstream power is borderline / too high and may be intermittently fluctuating even higher out of spec.The downstream power is a bit on the weak side as well.

 

In an effort to try to obtain better connectivity / more wiggle room, check to see if there are there any excess/unneeded coax cable splitters in the line leading to the modem that can be eliminated/re-configured. Any splitters that remain should be high quality and cable rated for 5-1000 MHz, bi-directional, and no gold colored garbage from Radio Shack, Home Depot, Target, etc.

If there aren't any unneeded splitters that can be eliminated and if your coax wiring setup can't be reconfigured so that there is a single two way splitter connected directly off of the drop from the street/pole with one port feeding the modem and the other port feeding the rest of the house/equipment with additional splits as needed and you've checked all the wiring and fittings for integrity and tightness and refresh them by taking them apart then check for and clean off any corrosion / oxidation on the center wire and put them back together again, then perhaps it's best to book a tech visit to investigate and correct.
