I've got a Belkin F5D7630-4A (uk) wifi adsl router. I use p2p software on my desktop (eMule and Azureus), connected via a wifi connection to the router. If I put the router under a 'heavy' load (maxing out my 0.5mbps adsl connection) then the router will routinely freeze after 1 day. The three largest chips on the board in the router become much more than finger hot, I'm assuming that the unit is overheating. I use a wifi connection from both desktop and laptop, I don't have a wired connection to the router.
If I run the router at 'half load' (fixing the max download speed at about 0.25mbps) then the unit takes up to a week before it'll lock.
When I say that the router locks, the behaviour I get is:
1. I can still open the router's config page via pointing my browser at 192.168.2.1. It'll report than it is connected to the web in the router config page.
2. If I try to access an external web address then the browser spins and times out. I've only tried using named domains, I've never had an ip address handy when it has locked
I'm assuming that the wifi/ethernet bridge is working (even though very hot), else the wifi access to 192.168.2.1 wouldn't work. Possibly the ADSL chip (I'm presuming there is one) overheats? As I've not had an external IP address handy, I don't know if it is just the DNS lookup that fails, or the entire external connection. Since the config page works I'm assuming that the core RISC chip isn't overheating.
Using the config page I can restart the router, and generally after one reset it'll just pickup again and reconnect to the internet and downloads recommence. Sometimes it remains locked, if I leave it for an hour and then reset again then it (I think always) works. This suggests to me that it is a heat problem. This is reliable behaviour for the last 6 months or so.
I now run the unit with the cover open, that seems to help though it still locks. Now I just fix my max download speed and I rarely get the problem (though 1/2 speed p2p'ing is a pain).
Has anyone had a similar problem, or can point me at evidence that this is a heat issue? I doubt I'll do anything about it - the unit is out of warranty by now and building an active cooler is a little too much effort, but out of engineering curiousity I'd like to know what's causing this problem. I upgraded to the latest firmware back after Christmas, that didn't do anything.
