DHCP Reservation

[mm2531]

I just replaced my 5 year old Dlink DIR-655 with the N66U. Upgraded the firmware to 155.

I am not too technically adept, so could someone tell me how to enable DHCP reservations?

I see a place to add manual IP addresses (LAN/DHCP), and I am not sure what that does. There is also a place to add "Specified IP" (Admin/System). I tried adding a reservation here, but then lost the ability to login to the router. The network was still operational but just could not login. Ended up resetting.

Appreciate any help.

Thanks

MM

Don't have an Asus router to confirm, but it sounds like Admin/System IP is the router's internal interface IP (what you point your browser at to connect).

Don't have an Asus either, but from what I saw on an emulator, just go to the LAN page in the Advanced Settings (lower left menu). Select the DHCP Server Tab. The lower portion will be what you are looking for (Manually Assigned IP aroud the DHCP list. You then just enter the MAC address of the computer and the reserved IP you want for it.

If firmware 155 is not like that(I think the emulator was 108), you should still look under the DHCP server page (or pages) for a place where you can list MAC addresses and IP, this should be the spot (under titles like reservation or manually assigned IP)

Hope this helps.

Thanks for the replies.

I don't think the Admin/system page changes the internal IP address. Tried logging in with that address, but that did not work. It also let's you add multiple entries, so it's still a mystery to me what that does.

I tried adding the reservation in the DHCP page. It's either broken, or I am not doing it right. It's lets you pull down the MAC addresses of the connected devices, and I typed in the IP I wanted it to have, but after saving it, the main status page still showed that the device had the old address. Tried rebooting the router to see if that made a difference, but no luck.

LAN > DHCP Server

Enable manual assignment-yes

Enter in your reservations

You have to release/renew IP on your device for it to get the reserved IP.

Thanks!

I will try that. I was doing everything except the ip release and renew.

A newbie question though - shouldn't rebooting the router after making the reservations have done the same thing?

Clients won't release their current leases if the DHCP server restarts. Clients are responsible for releasing their leases if they aren't expired yet.
