Hi

I am trying to link 3 buildings using 4 Cisco Aironet 350 Bridges and omnidirectional ariels. The buildings are in a line and I am using the middle building with two bridges and two ariels to bounce the signal on to the furthest building, the first building in the chain is connected to our LAN.
All has been set up, but the problem that I am having is that DHCP will not work in the furthest building, it works ok in the middle building, but I get a DHCP Server unreachable in the last building.
If I give a permanent IP to a machine in the furthest building then it will work fine, so it is not a connectivity issue.
All Buildings use the same Vlan .
Just wondered if anybody knows what is wrong, have I missed something, many thanks in advance

First of all why are you using omni's?
The design sounds, from your description, a little non-optimal. I'm guessing here, but it may have to do with forwarding/flooding across the wireless medium. Is there anyway for you to send or describe the design a little better?

Hi

Sorry its me being stupid, did I say I was new to Wireless.
You are right I would not use omnidirectional and I haven't, just posted wrong info, they are in fact uni-directional sorry.
The rest of the post is as it stands.

thanks

Ha ha ha ha Sounds goods! We've been there, typing one thing and thinking another! Any chance of getting a better description of the design and the issue?

Not knowing what OS you are running are you SURE that you have the compter in question to obtain an IP address automaticaly, because it sounds like it is using a bad SUBNET mask. the Subnet Mask should be 255.255.255.0 ANYTHING else would make it LOOK for some DHCP that was NOT there.

The reason I say this is that when you enter a STATIC IP you are fine. If the computer thinks its SUBNET mask is diferent than the SUBNET mask of the DHCP, it would be looking somewhere else there than the REAL DHCP for an IP address, and it would never find the REAL DHCP
