I bought a used WND3400 on ebay (seller said it was is great working condition, minor cosmetic damage) and I tried setting it up and have gotten nothing but grief.
I hard reset it to factory defaults when I got it, ran the setup wizard at routerlogin.com, and configured it using Windows 7. It worked for 3 minutes then it disconnected all the connections. Since then, I have hard reset numerous times, reconfigured it numerous times, and power cycled it numerous times. Now:
--the LAN connection works consistently
--the 2.4 gHz wireless intermittently disconnects and won't let me reconnect for a few minutes
--the 5 gHz wireless seems non-existent.
How the frog to I fix this so it doesn't disconnect me and I have both dual-bands working consistently? Let me know if there is anymore information I can provide.
I have also been getting a message since I've started using this router that "Windows has detected an IP address conflict." Related?
I watched my router (now that's I can see it lit up at night) and I noticed that it is resetting itself periodically for no apparent reason. Occasionally, I get an error message from Windows 7 that I have an IP address conflict. I looked in my event logs and these looked relevant.
