Ola,

I've recently noticed an issue with the D600. A few days ago, I could not get any IP address from the router (wireless connection) on one of my laptops. I checked the router and it did something never done before: It restarted automatically (orange lights). Everything seemed to work fine but now when one of my device connects to the network (ps3, iPhone, laptops...) no IP address is given by the router so everything is on limited connectivity which is really annoying. I have to turn it off/on to make it work. It happens most of the time.

Note that I already returned the router a couple a year ago or so (I cant recall what was the issue), so I have to say that the quality of this device is far behind my expectations.

Any input?

Thx

Link>Welcome!
What Hardware version is your router? Look at sticker under router.
Link>What Firmware version is currently loaded? Found on routers web page under status.
What region are you located?

Some things to try:
Turn off ALL QoS or Disable Traffic Shaping (DIR only) GameFuel (DGL only and if ON.) options. Advanced/QoS or Gamefuel.
Turn off Advanced DNS Services if you have this option under Setup/Internet/Manual.
Turn on DNS Relay under Setup/Networking.
Setup DHCP reserved IP addresses for all devices ON the router. Setup/Networking
Ensure devices are set to auto obtain an IP address.
Set Firewall settings to Endpoint Independent for TCP and UDP under Advanced/Firewall.
Enable uPnP and Multi-cast Streaming under Advanced/Networking.

Link>Wireless Installation Considerations
What wireless modes are you using? Under Setup/Wireless/Manual.
Try single mode G or N or mixed G and N?
Channel Width set for Auto 20/40Mhz or try 20Mhz only.
Try setting a manual channel to a open or unused channel.
What security mode are you using? Preferred security is WPA-Personal. WPA2/AES Only. Some WiFi adapters don't support AES, so you might want to try TPIK only or Auto.
Any cordless house phones?
Any other WiFi routers in the area? Use InSSIDer to find out.
Turn off WISH, and WPS under Advanced.
Try turning off Short GI, WLAN Partition,and Extra Wireless Protection if you have it. Under Advanced/Advanced Wireless.

Turn off all anti virus and firewall programs on PC while testing. 3rd party firewalls are not generally needed when using routers as they are effective on blocking malicious inbound traffic.
Turn off all devices accept for one wired PC while testing.

Thanks for the answer. I removed a DHCP reservation for one of my device and it works properly now. It's not a normal behavior though...

Usually by using Reservations for ALL devices, the router should work well. I don't recommend mixing Reservations on the router and having some devices using automatic with out being in the Reservation on the router. Sounds like you got it working. Enjoy.
