Wireless access point placement diagram

I have a small topology, with no routers at all.

We use the 172.16.2.x range not the normal 192.168.x.x

We have DSL speakeasy to a sonic firewall the firewall goes to a main cisco switch. the switch then goes to seperate departments. Netgear switches.

on one of the netgear switches we have tried to make our network wireless. We have our own DHCP and static ip's DHCP range 205-224

static ips all over the place work great. if you plug a laptop in the wall the dhcp server nt 4 service on a pc we use, gives the laptop an ip address just fine.

So it sounds like plug the wireless WAP right in right?

WRONG, i plug in, chan ge my ip address to configure to be on the ip address of 172.16.2.x

We config the Linksys WAP54G's to the tech support level 2 standards. we log out.

All our wireless laptops see the WAP and connect with excellent signal strength.

But no network computers pingable, no releas renew with ipconfig.

No internet.

And ontop of that cant even ping these WAP's. Its a good wap, we have 3.

Earlier we tried belkin wireless outers, they worked for a few hours, then the fimware cant be pinged.

Anyone know whats up???

This diagram obviously exists in a world with no microwave ovens, wire racks, concrete walls, electromagnetic motors and power boxes. Looking at that diagram is like taking a lesson in remedial wireless.

Now if the diagram had some upper and lower levels, microwave ovens, and some power cables running through the room, I'd be more apt to be impressed. I wish the wireless network I work with was so easy.

I think that diagram would be better for a home user to look at.....
