I have a D-Link Xtreme N Gigabit Router (http://www.dlink.com/products/?pid=530), which has worked fine for the past year since I bought it. I recently moved and changed internet providers. Now, once every day or two, the router stops responding - no internet traffic goes through, and I can't even bring up the admin interface for the router. I have to cycle the power on it, then it works fine again. LAN traffic seems unaffected. I updated the BIOS, what else could the problem be?

Try disabling DNS Relay at Setup > Router Settings > Router Settings and uncheck Enable DNS Relay. I've done a fair amount of reading on this fix and there's no noticeable performance hit. I have had the same problem with my DIR-655 and a DGL-4300 before that. The symptoms I experienced are that the internet would slow to a crawl then stop responding, LAN continues working, but the admin screen on the router does not load. Disabling DNS Relay resolved this for me. |

Can you PING the LAN interface? Can you Telnet into the LAN Interface? Is your ISP DSL perhaps? Your ISP may be resetting your IP address & the router is hung trying to acquire a new IP address. Power cycling the router causes it to work. You might try putting another (cheap) router in front of it (between the ISP & the DLink) to see it that router handles the DHCP issue. e.g.: ISP<===>Router1<====>Dlink<====>LAN Make suer that your LAN and Router 1's LAN are different subnets. |

Have you made any changes in your usage patterns? Many routers have issues with services like bittorrent. I've seen this happen with a few models of d-link and linksys and it behaves exactly as you describe. Basically anything that creates a big amount of connections like bittorrent and emule can cause your router to behave like that. |

I have a D-Link DIR-615, and it works great. I bought one for a friend for their birthday, and its the same model but a different HW Revision. It would suddenly quit allowing internet traffic for all but one of the connected computers, but they were still all connected. The one that worked was a MacBook hooked up by ethernet. It eventually quit doing this (after 3 upgrades and downgrades of firmware), and then my own started doing it. What was happening to mine, all of the IP addresses were being reserved for a device that had no mac address and never expired. So it would work for a day, then all of the addresses would be taken up and it would quit working. The macbook on the other router was fine because it was connected by ethernet and never had to renew its address. To fix it, I reserved the IP address for all of my home computers and have had no problems since. |

If you have your router set to .11n and near your router there is an AP set to .11/BG there might be some problems. |

Something you might want to consider: In this area, we tend to get frequent power glitches and brownouts in the summer months. If the power goes out-- even for the tiniest fraction of a second-- the router lights will be on but it becomes non-responsive. But, like you, a simple power cycle solves the problem. I'm not sure why the electricity going out for a second acts any differently than disconnecting the power cord for a second. But the solution was to plug the router into the UPS. P.S. My router is a LinkSys WRK54G wireless router. |
