Bandwidth drop
I am not new to wireless networks by any stretch of the imagination. I'm also not new to WDS, having run a dual dd-wrt network with a primary router and a secondary router as a repeater bridge with a 64-bit hex WPA2 key. I recently discovered that the repeater bridge mode in dd-wrt actually used WDS, which I was disappointed with. I know that with two WDS devices half of your wifi signal is used for the repeating while the over half is used for data. I'm also under the impression that for every WDS device beyond the first two, you loose another half of your available data bandwidth. What I have not had a Vance to confirm or deny, is wiener or not there is a repeater option out there that does not have the bandwidth decrease? Is this just a natural flaw with the wireless signal or is there a way to do a true wireless repeater wig no bandwidth drop, perhaps with a device with multiple radios?
There is something else I was wondering in regard to a wireless AP, which I have not truly used. If I set up an AP on floor 2 of a two story house, with a wireless router on floor one, do they have to be set up with separate SSIDs? Or is there a way to have them use the same SSID? The goal would be to let someone go between floors, using each floor's respective SSID, but not have to change networks. Any thoughts on that?
Thanks.
