Internet Speed

Hey I have a question about my internet speed and my modem/router, called in ealier today to find out that I'm supposed to be receiving 60Mbps but am currently only able to get about 17-18 Mbps. Was wondering if there is anything I could do to remedy this issue? I have power cycles my modem as required with no sign o fpseed increase. The modem I have from Comcast currently is the Technicolor TC8305C. Thanks

Re: Internet Speed

Is this with a WiFi connection ? If so, for a test, does a computer hardwired directly to the gateway device with an ethernet cable get the same speed ?

Re: Internet Speed

Re: Internet Speed

The speeds are on a desktop computer connected by ethernet directly to the Modem/Router combo, ca't seem to find the signal levels with this router. Most of the devices used in the household are hardware though, except a few phones.

Re: Internet Speed

Is this the information you needed? It was the closest I could find on my modem with the website you provided, also here are the logs for today.

Re: Internet Speed

Your signals look pretty good except you are only locked to two upstream channels. My feeling is that modem needs to be replaced, it was never really a great device and it's probably getting a little long in the tooth. You can swap it @ your local service center or if you like I can ask an employee to ship you a replacement.

Re: Internet Speed

Purchased a new Arris Surfboard SB6183 today, came home and got it set up to work with my comcast account but am still receiving only 18mbps instead of the 60 mbps. Am I just out of luck with my service or is there anything else I can do? Attached a similar document for this modem showing signal strength and power.

Re: Internet Speed

Call 1-800-comcast and ask the rep to confirm that the modem's provisioning, and your account data in their database is correct and complete and that the correct bootfile for your subscribed to speed tier is being pushed to the modem.

I've asked a Comcast employee to take a look at your account. You should expect a reply in this thread.
