WRT54gv6 wired interface hangs

Question

Hello, This problem has been bothering me for upwards of 6 months with no solution in sight. Basically every 6-12 hours the wired interface on my router hangs and none of my wired computers can communicate with the router or internet.
If a pc requests a dhcp address one is assigned in the router but the pc never receives the dhcp message. The behavior between devices is outlined below.
Wireless computers --> internet = good
wireless computers --> router = good
wireless computers --> wireless computers = good
wireless computers --> wired computers = bad
wired computers --> wired computers = bad
wired computers --> router = bad
wired computers --> router = bad
wired computers --> internet = bad
Relevant info:
ISP: brighthouse networks cable internet
PCs: 2 wired(linux), 2 wireless(OSX 10.5, Linux)
Other appliances: xbox360,wii,psp, laserjet printer
network use: gaming and internet browsing, no p2p
Firmware: v1.02.5 build 002, Jan. 9, 2008
So far the only resolution is to power down the router for 30 seconds and power it back on. I don't want to replace this router, but am approaching the point that the annoyance will win.
(although not related; my previous linksys wired router would also hang every 6-12 hours(different location, isp and hardware), so my opinion of linksys hardware is rapidly diminishing)

I'm sorry I should have been more clear, the WAN side is unaffected. The problem exists on the internal wired interface.
The interface between the router and modem is fine as evidenced by the fact my wireless machines can access the internet.The router obtains its DHCP lease without issue from my ISP.
Though I will say the config you listed is what I used prior to switching over to Cable from DSL, and the problem was still there.
I ran a test with Wireshark last night and confirmed the router is not transmitting any traffic on the internal wired interface when it hangs. DHCP discovery messages are sent, the router receives them and creates an entry in the client table, but there is no traffic whatsoever coming from the router.
I did some research yesterday and have learned that the consumer level products from linksys, dlink, and netgear all become more sensitive to heat over time(even their own internal heat)given that this router is over a year old, (and thus out of warranty) I think I'll open the case and put some heatsinks on the chips to see if that remedies the problem.
