Router flipping between 2.5 & 5Ghz, giving out the same IP address

[legocitytruck]

I have a netgear n600 wireless dual band n router at home.

http://www.amazon.com/Netgear-WNDR3...8&qid=1347219807&sr=8-1&keywords=netgear+n600

Lately it is creating a lot of trouble. It is intermittently turning on and off the 2.5 and 5 Ghz radios which is causing devices connected to one radio or the other to temporarily loss internet connectivity.
Additionally, it is giving out the same IP address to multiple devices (computers, printers, phones, etc.) in the house causing the error message (two devices have the same IP address) to pop up on some of the computers. What is causing these errors?

I'm not suprised, given my experiences (crap ISP cable modem/router) and general opinion about Netgear.

You might want to check for firmware updates. If that doesn't solve your problem, there're a few things you can try before buying a new one:

• Make sure the radios have different SSIDs and aren't in the same channel as other nearby networks (you can use software like inSSIDer to check for other networks)
• Disable the DHCP server function on the router. If you have another device (like a secondary router working as an AP) use that device's DHCP server instead. If you don't, assign static IPs to everything.

you could try installing dd-wrt on it
the n600 is model WNDR3700

All the Brand names have Crappy Models.

However Asus, Cisco, and Buffalo, here and there have few Models that are really Good.

Unfortunately, Netgear, and D-link, TrendNet and others, aside from the usual "Crappy" have (here and there) only decent Models (I.e., would not qualify for Good).

That said many End Users do not need any thing special with the Wireless (like 2 devices within 10-20 feet), in such cases Decent will work for them too.

Haven't read the post in detail because I have to run.

- Make sure it's dual-band simultaneous
- If the network is unsecure, make sure the SSID is unique to avoid crossing traffic and IP conflicts
- Make sure any devices with manual IPs are using a different range from the router's DHCP
(for example, configure the router to give out IPs starting with x.x.x.100, manually configured devices should use x.x.x.99, x.x.x.98, x.x.x.97, etc...)
