need aggressive roaming capable usb wireless adapter suggestions and be able to set minimum wireless speed manually

I need aggressive roaming capable usb wireless adapter suggestions and be able to set minimum wireless speed manually. I have three ap's with same SSID. I want the cards to jump if the speed goes below 20 megs.

Could anyone suggest some products?

Well, I haven't found any adapters that let you set a minimum... you might be able to specifiy that in the router, though.

Did you mean connect speed or true throughput, btw?

True throughput of a 54g connection is typically only 40-45Mbps, of course... and 2 clients would cut that in half; if more than 2 it wouldn't matter how high the connect speed you enforce - they wouldn't be able to muster 20Mbps speeds if they were all transmitting or receiving simultaneously. And WEP or WPA-PSK lower those throughput figures by 10-15%, too; WPA2-AES security does not lower throughput after initial authentication, nor does 802.1x RADIUS (usually called WPA/WPA2 Enterprise).

Understood... I only mentioned the T1 speed for comparative bandwidth.
e.g. 10Mbps is sufficient bandwidth for transferring a 100 mebibyte file in under a minute and a half, or a 700MB CD full of data in under 10 minutes.
What if it can't get above 20Mbps on any other AP either?
Do you want it to keep hopping from one to another in that case?

Then I would want no connection at all. We have an applicatin that needs a minimum mount of bandwidth to work. Is there a way to have some sort of smart adapter that I can specify the minimum bandwidth needed? It's better to not have a connection than a terribly slow one. AT that point I would just add more AP's to fill the voids, but we can't have the slow connecton.

Thank for any info on this.

20Mbps is a lot of bandwidth, even deducting overhead.
A full T1 line is only 1.5Mbps.

I'm not aware of any adapters you can specify a minimum on, but I'll see what I can find.

are there AP's that provide 40-45Mbps per client?

Or to have the client get that full 40-45Mbps do I need a seperate AP per client? That would sound silly. There are AP's at other places serving 20-30 people.
