I have a computer on my main floor and I have a second in the basement
that my daughter uses. Each has it's own modem connected via Ethernet.
I've noticed that each has the same IP address.
One computer's I.E. explorer access speed is very slow when both are
on at the same time and sometimes when only one is on .
I'm not very savy so respond in 'for dummys' language.
Is my access speed caused by the multiple modems or do I have a

Comcast only allows one modem to be used unless you're paying for multiple separate internet services. If you are using multiple computers, you can use a (wireless) router to prevent the issue you are having, but if you want to use two separate modem simultaneously, then you need to have 2 separate internet accounts.

Wired will be faster and less prone to wireless interference, but N-routers are not terrible if nessessary. Also, speed will depend on if your wireless computer supports N or only G. Personally, I use wired for all downloads and gaming, but for casual browsing or school work, wireless N is okay.

I'm curious as to how the two modem setup you have is even working. Only one of the modems is probably provisioned by Comcast--or they would already be billing your for both connections...or do they?
If you were being billed for two connections you should be seeing separate IPs...so I doubt that's the case.
BTW, it is possible to have two modems operating at one service address. If you already had High Speed Internet service and add phone, sometimes the installer will just split the cable run and leave the existing HSI modem in place.
But you can't also use the eMTA for an internet connection, in that situation (as I understand it, anyway).

but you'll still only get provisioned one IP address, which will cause some issues.
I'm curious as to exactly what kind of "issues" ?
