Problems with Wireless Devices getting IPs
« on: December 21, 2009, 06:41:08 PM »
Good evening...

Product is: DIR-615 REV C1. and FW VER 3.10NA

DHCP is enabled.

None of my wireless devices are able to obtain IP addresses through DHCP.  I have to statically assign them, at which point they connect flawlessly.

Devices connected to the router via a network cable get IP addresses just fine.

Any thoughts on how to fix this?

Hello, I'm sure you've tried the obvious, like power cycling the router. I've seen some problems that have been corrected by a hard reset. On top of that, you can try updating the F/W to 3.11NA, then resetting everything to default. If that doesn't work, maybe posting the logs will help. Logs are stored on the Status page. Enable "Debug Information" from the Log Type list.

Other info, like client OS type & whether the same client can connect via wired port (it wasn't clear if you used the same devices on wired & wireless) would be useful.

Good Luck!

Hi, the main difference between the wired hosts and the wireless hosts would be in the authentication. Barring any problems with the wireless hardware itself, from your description it seems DHCP is working because your wired clients get an IP. Since the wired clients do not have to authenticate and the wireless clients do, have a look at your wireless security settings. Also keep in mind that the one caveat is mac filtering, this applies to both wired and wireless, so turn that off temporarily if its enabled so as to not confuse your troubleshooting efforts. The basic connection sequence is as follows. Client locates the SSID and configures itself for connection (channel, rate, standards). Association is attempted with authentication taking place. DHCP request is sent then the IP, mask, gateway is assigned to the client.

Other than that I am not sure what else to look at because at this point in time I am finding numerous issues with the current firmware 3.11NA on the 615; but with mine the DHCP and Wireless are working.
