Currently I have a Belkin G Plus MIMO Router, a Linksys CM100 Modem and a Linksys Network Card (Not sure of the exact model), and my ISP is Atlantic Broadband.
Two weeks ago, we had a huge storm in our area, and my router/modem were the target of a lightning storm (I had it plugged into a surge protector, but for some reason... that didn't help) - and I replaced both my router and my modem. I had a Motorola Surfboard SB5120 and a random Belkin Router (Don't remember the exact model sorry). And before that storm, my internet worked fine, I could idle for a good 10 days without disconnecting.
However, ever since... my internet has been disconnecting randomly for a split second (or so it seems) or just long enough to disconnect me from whatever I'm doing. Which makes downloading files, playing online games, and even chatting on a messenger program a real annoyance. The thing is, I don't even think my computer registers it, because I don't get a "x is now disconnected" or whatever. And it really wouldn't be that big of a deal... but, it's reoccurring, and it happens anywhere from every five minutes to an hour. I haven't been steadily online for over an hour since.
I have called my ISP numerous times, however - every time they tell me that there's nothing they can do, that there's nothing wrong on their end.
Also, I have tried connecting my modem directly to my computer, but all it gives me is a little bubble message that says "Limited or no Connectivity."
It's getting to the point where I'm about to give up, I've spent ~$150 on parts, I really don't have that kind of money to be throwing around. It's just so frustrating.
Anyway, if anyone can help... or has any ideas, it'd be greatly appreciated.

Sorry, I forgot to mention. I am NOT on Wireless. I am connected to my router through the WLAN port thinggies. And I have tried switching them (My router has four on the back), but no luck.

When you connect your PC direct to the modem did you verify that you have the correct patch cable? Many routers have auto adjusting ports so it doesn't matter whether you use patch or crossover cables.
The other thing to try would be when you switch over to direct PC connection, perform a power reset on the Modem and PC in that order.

Here's something you can try that might help.
Uninstall the TCP/IP stack and then reinstall it. I've had it happen to me in the past where something in the stack gets corrupted and a similar problem arises.
If you're not sure what to do, right click on your "My Network Places" icon (on the desktop) and select "Properties" from the menu that comes up. In the window that opens, right click on the network connection (likely it's called "Local Area Connection") and select "Properties" again from the menu that comes up.
In the window that opens click on Internet Protocol (TCP/IP) to highlight it and then click on the Uninstall button.
Once it's removed, reboot. Redo the above and when you get to the property sheet for "Local Area Connection" you'll want to click on the "Install" button. Select "Protocol" and click the "Add" button. Choose "Microsoft TCP/IP version 6" and click on "OK".
NOTE: Before doing this, open the TCP/IP properties on the network interface and check to see if your TCP/IP info is automatic (DHCP) or statically assigned. If static, write all the info down as you'll have to reenter it manually after reinstalling the TCP/IP stack. If it's automatic (DHCP) then simply open the properties after reinstalling the stack and make sure it's set to "automatic"

@Curt R, whenever I go to my TCP/IP properties, and highlight that - the Uninstall button isn't high lighted. (Image URL)

Which part didn't you understand? The power reset part? That just means switch off/ disconnect the power and re-connect.
The other part about patch/crossover cables simply means that there are two kinds of RJ45 cable. Crossover cables are used to connect LIKE devices. eg two computers.
Patch ( sometimes called Straight) are used to connect UNLIKE devices. eg Modem to PC.Some routers and switching hubs can automatically sense the kind of cable plugged into them and adjust the port configuration in order to make a connection.
In other words if the router detects that a crossover cable has been used instead of a Patch cable it will make an internal adjustment of the port to mimic the correct type of cable. If you subsequently unplug that cable and connect a different device with possible the opposite kind of cable the router cannot self-adjust a second time unless you do the power reset of the router.
Issues involving "Limited or No Connectivity" usually result from incorrect or faulty cable, or failure to do a power reset when making changes.

That's pretty strange! You may have to login as the Administrator then to un/reinstall the TCP/IP stack.
