peer to peer network with some switches and a bridge ( Setting up bridge with DLink DWL3200AP )

I am trying to help out with a small school network that is basically a business class cable modem with a series of switches and a couple of access points. We are trying to bridge the network from one building to another using a pair of DLink DWL3200AP access points.

Problem:
We think we setup the bridging features correctly with WDS. We have both access points on the same channel. Both have registered the MAC addresses of the other. But the laptops we are using to test the connection to the bridged access point cannot make the connection. I seem to be able to connect to it using my iphone and random computers throughout the network. I suspect it might be a more fundamental issue. I am not familiar with such a big peer to peer network being chopped up like this.
- Do I need to setup each access point as a DHCP server and dole out a range of addresses unique to that access point?

I have attached a diagram of the network. Any suggestions would be welcomed.

On such a networkj you wouldn't normally put 2 DHCP servers, I suspect that would make things even worse.

Am I right in thinking that you just want to use the dlink access points to bridge the network, but the client computers connect via cables ? .. ( as there are various choices available with the dlinks re bridging more, AP mode., or both).

Over in the middle school we would like the WAP-MS to connect to a switch and have the teachers computers connect there. But It would be nice to leave the WAP feature turned on over there too.

Do you need WAP-N  *and*  Wap-MS to act as Access Points for wireless client?

Also, can you confirm that you're *not* using WPA as the encryption on these 2 APs, as I believe you can't use WPA when you have the WDS bridging in place.

I do want WAP-N and WAP-MS to operate as Access points. But I think it would also work well  if WAP-MS was only connected to a switch over in the middle school.

As for WPA security, that is what we are using. I saw some discussion in another area that had mixed comments on the WAP security being used. Some said it was ok as long as they had the same key. A definitive answer would be helpful. We are actually using the WAP Personal setting.

Can you try it with WEP just to rule that out.  If you do a google on  dlink, wds and wpa problem quite a few postings come up.  eg http://www.expansys.com/ft.aspx?k=40509

Now that you have me wondering about WDS and WPA security compatibility I did a search on just that generically. It does seem that there are some issues here. There are some comments in the following article that indicate that they can be used together if they use static keys. It also mentions that some apple products might be an exception to this. Anyway, it seems that to eliminate the problem, for now we will try WEP. http://en.wikipedia.org/wiki/Wireless_Distribution_System

I will also turn of wireless access to the bridge to increase throughput.

I will need to experiment with this. But I believe it points me in the right direction.
