Having recently gotten reconnected to my own service, I opted to use the same Cable Modem and Router I was using previously with the same Provider. The Modem is a Motorola Surfboard SB5102, and the router is a D-Link DIR-655.

One PROBLEM I have had is that, infrequently (maybe every few hours) the router, by all indications, is resetting itself. At first I suspected the cable modem, but then I noticed that I also lost the ability to access the router (ping or http setup pages) when I lost the connection, additionally, I connected the cable modem directly to my PC and did not have any problems either.

I feel I've isolated the router as the cause of the problem. Note that this router, when I last used it a good year or more ago, worked perfectly fine in conjunction with the same Modem, and to my knowledge has not had any extensive bumps or bangs in the meantime. However, it was outside when I tried to sell it at a garage sale (which it thankfully never got sold at).

I figured that the router might be resetting because it is overheating. The router- like most- usually got fairly hot, but it was all I had to go on, so I took off the case and let it sit free of it's insulating cover. However it doesn't seem that has solved the problem.

My only other idea is to continue running with the idea that it is overheating and see if I can find my tube of Arctic Silver and try re-applying the two Passive heatsinks inside the device, but it might still be in the box of stuff I have in storage.

I do have a WBR-1310 to use as a backup, but I'd much rather use the DIR-655 if I can. Additionally I wasn't able to get any wired connections to work through the WBR-1310, so that will probably just be switching out one set of problems for another.

Anybody else have any other ideas?Additional: I took the problem router apart completely. It appears to have some mild corrosion on the other side, which I attempted to swab off with some Nail Polish Remover. Not really sure if that was the best material to use, but I have nothing to lose, as it works now the router is a gigantic pain. In the meantime I'm using the WBR-1310, and I managed to get the wired connection working, Though I imagine the little fella has seen better days.

I'll give the DIR-655 another go after a day or so of air-drying, and hopefully in the meantime this one doesn't give me any problems, since it looks like it's my new go-to router, which should work fine, but would be a shame to have to junk the more expensive one.Odd that corrosion would happen like that. There are some corrosive fluxes out there, but I haven't seen them used in years. A toothbrush you don't plan on using ever again and rubbing alcohol usually does the trick to remove corrosion as well as flux on PCBs. You can bathe the board in rubbing alcohol and it wont hurt it in a non powered state. Just air it out dry and it should do it if the corrosion was the cause.

Also to mention that I had a client once with an issue similar and it was that they had dips in their power, and the dips caused resets on some hardware while leaving other hardware ( not as sensitive ) alone. Solution was to power all their hardware thru a UPS which kicks in fast enough to cancel out the dip by use of its battery. Now everything is running fine and they just hear some clicks from the UPS throughout the day when its keeping their power as a constant doing its job.

I think the big issue was that I tried to sell it at friend who was having a garage sale, so I gave it to them along with some other stuff. When I went there a few day's later I found it covered in pine needles and sitting out in the open, so I decided I would NOT leave it there or sell it since they obviously have no idea how to care for electronics. (That and the fact that they tried to give it away for free while I was there, along with some of my other stuff).
