AC68U - DHCP Issues w/ WiFi - Takes 10 mins

[Jason]

Hi,

I just picked up the Asus 68U after reading great reviews here and other places. However, I have been trying to resolve some issues with WiFi for last week or so and no luck..
I have both 2.4 and 5Ghz setup on same SSID. When any of the devices connected to 5Ghz go out of range (one part of the house), the WiFi drops; which immediately it should connect to my 2.4Ghz.

Well.. it tries. It tries to connect to 2.4GHz but it sits there and it takes anywhere from 6-10 minutes before the Router hands out an IP. Now if I am within 15-20ft of the Router, its almost instant. Router is in the basement and on main floor - anything really takes 6-10 mins depending on what part of the house you're at. I have full bars on 2.4 throughout the house.

What I have tried:
-Separate SSIDs - to manually switch to see how long it takes
-Turned on/off - beam forming
-Reserved MAC Address to IP in the Router
-Different Channels for both 2.4 and GHz
- Static IP on the devices

I have tried it on both Asus 3.0.0.4.376.1663 (latest) and the Merlin's latest build. Maybe I am missing something.. Old Linksys plugged back in still provides IP speeds fast so not sure what's going on.

Any help would be appreciated.

Thanks
Jason

That's odd - esp. if you have Static IP's outside of the DHCP scope used...

(in other words, if DHCP is handing out addresses 192.168.1.100 to 192.168.1.150, you should use something above or below that range, such as 192.168.1.10 for example).

In the case of DHCP assigned addresses, this is outside of the radios on the AP, and the IP address is bound to the MAC address of the client, not to the MAC address of the AP radio.

And since the AP has already granted access via WPA2, this shouldn't be an issue here as well, as the handshake has already occurred...

At the radio chipset level, this should be a Layer 2 transition, and it should be fairly transparent if the PSK keys and SSID is the same for both radios.

Bug perhaps?
