Please give us more information:
Please connect your computer directly to the modem via Ethernet ( no router, no wireless, no USB )
Run ShaperProbe and post your results. (It works with Win 7)
3) Post your upstream and downstream signal levels (click the link.) We are interested in your power levels (dBmV) and your Signal to Noise Ratio (SNR).
Let us know to what speed tier you subscribe.
5) Post the make a model of your modem.
6) Post your modem's error logs.
Connection and trouble shooting tips (How to check signal levels.) . Info you should post to get help.

where do I find error logs?

Are there any excess/unneeded coax cable splitters in the line leading to the modem that can be eliminated/re-configured ? If there aren't any uneeded 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 putting them back together again, then perhaps it's best to book a tech visit to investigate and correct.
As far as buying your own eMTA, the current consensus is that the only customer-owned telephony modem approved by Comcast is the Arris TM722G, which you must purchase from your local Best Buy (if available) that has a Comcast Communications Center/kiosk. About $150 for the modem plus professional installation. Some stores/areas will allow a "self install". Those may supply a kit that looks like this;
Also be advised that some market areas do not allow customer owned eMTA's at all. It's best to call in a see what your market area's policies are.

I had a small tv hooked to the same splitter as the modem. I have taken that tv off and now the internet is working fine. I guess I will have to move it to a different area.

So you removed the T.V. from the mix, what about that splitter ? Perhaps the T.V. was injecting extraneous noise in to the line. For curiosity, what do the signal stats look like now ?
