Today we're running a Mikrotik 1100AHx2 at our office where we've four floors on different subnets. Now I'm looking in to setting up a Wireless network spanning across these floors using Access Points, but all connected to the same router port so it's completely isolated from the rest of the networks, but still using the power from the switches from each floor.

So my question is, what kind of hardware would you use for this, and have someone made such a setup before?

This is quite hard to explain, so I drew you a picture to make it easier to understand, if you have any questions please just post them beneath, and if serverfault was the wrong place to post this, I'm sorry and please move it to wherever you want.

Best Regards Lars Wifi setup

Yes this is possible. You need to set up repeater/universal repeater mode on those APs.

Check TP Link WA 730 RE models...

Note: Do not expect miracles because it all depends from the signal between whose APs. Also, do not overload APs with to many users...

Would this create 1 single SSID+pw that devices would automatically be switched between, or 4 separate? – Lars Jun 13 '12 at 11:09
Yes. As you can see here there is no SSID option when Range Extender mode is selected. – mangia Jun 14 '12 at 7:12
Ah, so if I have 1 of those in AP mode and the rest in Range Extender I get 1 single big wifi network then? and all devices connected will get IP addresses from the DHCP server in the Router, right? – Lars Jun 14 '12 at 8:18
Right. Just be sure that DHCP servers on every extender is disabled. The only DHCP server you'll need is router dhcp. Also, be sure that router IP address and IP addresses from the APs are not the same... Some extender will require "DHCP Relay" turned On (in case this option exists.) – mangia Jun 14 '12 at 10:20
