Networking :: Linksys E3200 Could Not Take Dump In Less Than A Month N600

I used to use this forum all the time when i was younger and I pretty much learned most of what I knew about computers from this website (the rest I learned from breaking stuff and then having to fix it). I'm really excited to be back on this website and learning about computers again. The latest generation of consoles really pulled me away from playing my video games on computers and thus i no longer felt the need to over clock everything. Now, for my current problem:

I just recently purchased a linksys e3200 router and have been using it in place of my Belkin N600 (which i bricked ). The router is ran to my cable modem (which is located behind my TV) and the router itself is located about 6 feet away on top of my fire place mantle. The router is connected to my ps3 slim 250gb and my motorola sb6120 both with cat6 10 ft cables at 1gbps. I have a amd laptop with built in wireless g, and intel laptop with wireless g, a pc with a wireless g usb and a wii all connected to the router. Thus, the router stays in wireless g broadcast mode.

THE PROBLEM is that the router will work for about 30 seconds to 30 minutes and then it just starts crapping out. All the computers lose their wireless connection to it, and it would seem that sometimes an online game for ps3 gets bad packetloss during this dump. The only way to fix the problem is if i reset the router. A soft reset works for about two minutes, and if i do the 30-30-30 reset, it starts working again for another 30 min to an hour.

Here is what I already know:No known source of interference near the router.nly one other network in the area, and I have tried every available wireless channel.Have not only upgraded to latest version of cisco firmware, but now I am using mini- DD-WRT.Have tried increasing broadcast power on DD-WRT.Have played with the settings in DD-WRT pretty extensively after reading the guides on what settings do what.

The connection issues still happen even if my laptop is 3 feet direct line of sight from the router.It would seem that the problem happens with wired as well, just that it recovers so quickly on wired that most people wouldn't notice.

My cable modem typically averages between 20-30mbps down and 1-3 mpbs up (i moved to a small rural area that charges extortionate prices for better packages). I can't afford a wifi spectrum analyzer tool.

Here is the kicker for me: EVERYTHING worked flawlessly until one day it just quit working. Absolutely nothing was changed. Some of my computers are very far away and on a different floor in the house, so if I have to get another router it's not the end of the world because i can just put this one on repeater mode. I just don't understand how a rather well-received router model could have such bad issues.

Any ideas apart from the typical: location, firmware, interference, channel, channel width, reset ideas? Even now, the router works very well until it goes back on life support.
