Try opening up Resource Monitor on your computer, clicking on the Network tab and noting what processes are using the most amount of bandwidth, what ports are being used and the TCP connections that are open. Type resmon.exe in the search bar to open it, and let it run for a while to monitor your connections. Post back with the info.

That might be your issue. The modem is an older model and, according to Comcast, is only recommended for lower tiers of service. You might want to check here to make sure that model is compatible with your service level. http://mydeviceinfo.comcast.net/

I'm using BLAST speed service and from the looks of it I do not see my modem on there. So my outdated modem could be causing high data usage?

The modem is an older model, it doesn't seem to be recommended for your service plan, and you've installed third-party firmware on it. So at first blush, yes, that appears to be the issue.
If you want to be sure, run Resource Monitor on all your computers and laptops and log the network usage, just to make sure there's nothing on your home network that is generating all that traffic. If the total bandwidth usage on all your machines is less than what the Motorola is logging over that same period, then it's definitely the modem.

The third-party firmware was installed three days ago because I had three months straight of high data usage. The resource monitor shows chrome.exe everywhere but only about 600(B/sec) is sent and 1100(B/sec) is received. The data usage on the resource monitor seems why lower than what the modem is saying. I'll replace the modem and see if the data usage goes down. If it is the modem then I will feel like a complete idiot :\.

That model is 8 years old, if my information is correct, and after a while modems and routers will start to act up, sending out bad packets, etc., that can result in lots of unnecessary traffic. Plus, if Comcast doesn't support it for your service plan, there will be other issues as Comcast and/or the modem try to negotiate certain types of network traffic unsuccessfully.
Don't feel that way. These things happen. Post back if the new modem doesn't solve the issue.

You don't put dd-wrt on modems but on routers. So what router are you running?
Most routers have bandwidth control which means you can log/monitor which device is doing all the internet talking. Using the same utility you can also limit the amount of bandwidth so you can shut off internet before you go over your quota.
This, of course, depends on what router you are using? Make and Model?

Some of the things that run in/on chrome stay running in the back ground all the time, even when the browser is not opened. You said your laptop was off, was it completely off or just hibernating?
Hope this helps

Yes I meant that I installed dd-wrt on my router sorry for the confusion. I use a Linksys/Cisco E900 router and it doesn't come with a bandwidth monitor that's why I installed dd-wrt. I installed the new modem it's working fine so far. I'll post tomorrow if my data usage is back to normal. Hopefully this fixes the problem. Thanks everyone for the advice. Fingers crossed it works.

OK sorry but the high bandwidth usage is still happening. Even with the new modem so far in 4 hours 9gbs of data has been used. I would like to know how to get to the Comcast forums Queen. Thanks.
