I have a D-Link (DIR-655) wireless router connected to Time Warner Cable internet. Frequently, the internet connection stops working on all devices, though I can still connect to the router itself. The lights on the modem show that the internet is working, and the wires are all connected correctly. Often, the internet can be restored by resetting the wireless router and waiting a minute. I recently updated the firmware on the router, but that doesn't appear to have helped.
What is going on and how can it be fixed? Thanks!

I have a D-Link and have had similar issues. Once in a while (used to be once a week on average) the router would suffer a crash in its wireless stack. This can be easily verified: you cannot browse to the router's admin site - it's down. But if you connect a laptop to an ethernet plug on the router, you can surf.
If you look at the D-Link forums for the 655 and 825 models, you'll find dozens of complaints. D-Link ignored this for several months and the started to try addressing it by a series of firmwares. In the case of the 825 they even came out with a B-model that fixes most problems (not that it helped anyone who had the A already).
The latest release seems to do the trick for me: I now average about a month between crashes. What seems to exacerbate the crashes is downloading large quantities of data, particularly if you use BitTorrent. The higher the download speed, the higher the chance of a failure.
So, upgrade to the latest firmware, avoid going over 500Mb/s downloads and you should be fine. Alternatively, do what other people on the forums suggest and ditch the D-Link.
