LinkSys E2500 Internet Problems

Question

Hello, I've recently bought an E2500 Wireless Router for my home, but every 1-2 days I've been having an issue. 
The internet connection will suddenly drop. Upon checking the "Internet Connection" information, under "Status" I see that the internet IPv4 address field is all 0.0.0.0, when it usually is not. I've tried everything to fix this but the only thing that seems to work is for me to hold down the reset button until the router returns to factory settings then use the Installation CD to set back up my Wifi.
After that it will work for a while then some time later stop yet again. It happens over and over again and I'm not sure what to do. I can confirm it's NOT the Internet Modem that's the problem, if I connect my laptop directly to the modem I get internet. And I've called my ISP but they say it's a problem with the Router itself. I Googled the issue and saw that some cable internet providers (My internet provider is cable based) require you to set the MAC Address Clone to "on" which I did and cloned my laptop's MAC but this too has not worked. Releasing and Renewing the IP address also does not work. 
I THINK this happens everytime the DHCP Lease time runs out, but I am unsure. Any help that can be given on this would be appreciated, else I may have to return this router and get another.

Internet Service Provider and Modem Configurations
What ISP Service do you have? Cable or DSL?
What ISP Modem Mfr. and model # do you have?
Is ISP Modem/Service using Dynamic or Static WAN IP addressing?
What ISP Modem service link speeds UP and Down do you have?
Check cable between Modem and Router, swap out to be sure. Link>http://en.wikipedia.org/wiki/CAT6 is recommended.
Check ISP MTU requirements, Cable is usually 1500, DSL is around 1492 down to 1472. Call the ISP and ask.

For DSL/PPPoE connections on the router, ensure that "Always ON" option is enabled.
If the ISP modem has a built in router, it's best to bridge the modem. Having 2 routers on the same line can cause connection problems: Link>http://www.practicallynetworked.com/networking/fixing_double_nat.htm and http://cognitiveanomalies.com/cisco-nat-how-nat-works/ If the modem can't be bridged then see if the modem has a DMZ option and input the IP address the router gets from the modem and put that into the modems DMZ. 
I recommend that you have your ISP check the cabling going to the ISP modem, check signal levels going to the ISP modem. For cable Internet, RG-6 coaxial cable is needed, not RG-59. Check for t.v. line splitters and remove them as they can introduce noise on the line and lower the signal going to the ISP modem. Connecting to the ISP modem could result in a false positive as the signal to the modem could be just enough to that point then adding on a router, could see problems. Ensure modem is working well too. Bad modems are out there as well. The router operation is dependent upon getting good data flow from the ISP modem and the modem is dependent upon getting good signal from the ISP Service.
Router Placement
Forum User - "Well I feel really dumb. After moving the router away from other electronic devices my speeds are back to normal. Just a heads up for anyone experiencing slow speeds, you might want to move it away from other electronics and see if that helps."
3-6' feet minimum safe distance between devices.
Placement on main level floor and central in the building and WELL ventilated is preferred. Not in basements or closets as building materials, or near by electronics devices could interfere or hinder good signal propagation.
