EA-N66 Question (DHCP)

[D'Artagnan]

Hi Guys,

I've looked and cannot find and answer to this question so here goes! A customer bought one of these and asked us to configure it for them. They have a DSL2+ connection to a Draytek 2830 router. This is connected throughout the premises via cat6 and also has wireless enabled (which works perfectly for upstairs) and provides DHCP etc..

The N66 is set up downstairs, connected via UTP back to the draytek. It's set up in AP mode.

Everything works fine for a day or for, then, for whatever reason, the N66 starts issuing IP addresses to devices connected (both wired and wireless), effectively disabling them due to incorrect gateway addressing.

But I cannot find any where to set either DHCP off or DHCP forwarding. Anyone got any clues?


TIA

D'Art

I had the N66 set up as a wireless repeater with the same issues. It seems that if / when the N66 looses it's IP address it won't attempt to renew it right away. Here's my setup:
Router: RT-AC66U
DHCP & DNS turned off (Have a server running as both)
When the router for whatever reason would loose connectivity or the server would, the N66 would loose it's IP and NOT renew it, instead creating it's own DHCP server. I had some issues with my DHCP server and could not get it to restart the server role because it said there was another DHCP server on the network (the N66 repeater). Unplugged the repeater and my DHCP server came back up just fine.

There is NO option that I have seen to disable this feature in the N66, so I have had to stop using it as a repeater for now. I have been using it fine as a wireless adapter though.

Hopefully ASUS will change the functionality of this in a future firmware update. There are a lot of us that would not need the N66 being a DHCP server since that is what the ROUTER'S job is...

The EA-N66 acts as DHCP temporarily when the main Access Point is off. This is temporary so you can access the EA-N66's interface. After it starts receiving connection from main AP again, it will force connected clients to reconnect with the proper information.


Do you mind if I ask what firmware is being used?

wvaj, Can you clarify your scenario?
1) Is your setup: DHCP server -> RT-AC66U -> EA-N66 -> client ?
2) Is your RT-AC66U set in AP mode or Router mode?
3) Does your DHCP server change the IP Pool (ex. 192.168.1.x change to 192.168.10.x) and the EA-N66 cannot renew the IP address?

Initial testing of the described "DHCP" issue has not produced the results that are posted here. Any more information provided would be helpful.

modem -> AC66U (router mode) -> DHCP server (port 1) 8 port switch (port 2) with a couple other devices
I did have my N66 setup as a repeater before I was running into too many problems with it's own DHCP server kicking on, then my server would shut down DHCP services stating that an existing DHCP server existed. I haven't ran into the same problem with the N66 in adapter mode.
My Server does give off 1.x addresses just because I'm so use to working with that block.

With what you were describing with the temp DHCP server, I suppose it could have been when my router would have issues with the wireless - I've posted that in another topic.

I have the same issue.

I'm using a Netgear wireless A/C router. It's almost as if my Asus-EA N66 has completely hijacked my DHCP.

I use my laptop for work, and before I purchased the N66, I could leave the Laptop's wireless and LAN adapter IP4 settings to automatically obtain with no problem. Now after the purchase, I have to manually configure the IP4 settings while at home in order to receive a connection, and then set it back to automatic while at work. It doesn't matter whether I connect via wireless or through the laptop's onboard ethernet adapter... it also doesn't matter whether I connect to the Asus wireless signal or my netgear's wireless signal. The result is still the same, I'm presented with an ASUS error page until I manually configure the IP settings.

I haven't been able to find an option on the asus either.
