I have a clients house that they have installed a cable modem on each floor of their house (6floors) and they had a wireless router installed on each floor also. They want to be able to connect to each router when they are within site without having a gap in connection. Becuase the house is in NYC and its all brick it is not possible to run cabling to each router so setting up a roaming profile wont work becuase they are not WAP they are each their own network. I have set each modem to have a unique SSID and different channel. Any suggestions? E6300 OC'D, 4GB Ram, 8800GTX, Liquid Cooled, Dual SATA DVDRW DL in a thermaltake case

That is about the best you can do. For 6 floors, I would recommend the following: Floor 1 --> Channel 1 Floor 2 --> Channel 6 Floor 3 --> Channel 11 Floor 4 --> Channel 1 Floor 5 --> Channel 6 Floor 6 --> Channel 11 Channels 1, 6, and 11 are the only non-overlapping channels in the 802.11g band.

"They want to be able to connect to each router when they are within site without having a gap in connection" Simply not achiveable with that setup. They will have to have a gap as they disconnect from one AP and connect to another. Really should drop a number of those isp connections, put in a dual port wan router and wire the building. Everyone could be on the same subnet and then you wouldn't have a break as folks when from floor to floor. Imagine the power if you knew how to internet search

If you have 6 modems, does that mean you have 6 accounts and 6 addresses?

Yes the owner of the house can not put wholes in the wall and refused to have wires runnning through the house. So there is six modems with six routers and I need to atleast be able to keep all networks from clashing. I assigned seperate channels and SSID's. Should I change all SSIDs to the same thing. I already have the WEP key the same on all networks to make things easier. If I have all SSIDS the same would this provide a more consistant conneciton? The router will dual connections is a nice idea only problem is they want everything wireless. I can stand in one spot and pick up four routers but even with different channels and SSIDs the signal drops. E6300 OC'D, 4GB Ram, 8800GTX, Liquid Cooled, Dual SATA DVDRW DL in a thermaltake case

There is no way you can be successful with that criteria. Imagine the power if you knew how to internet search
