Should I be able to connect a 802.11b laptop that only has WEP security with a wireless router that is set to WPA2 security?

I've gotten on hotspots with this laptop, and I can't imagine that every laptop connected has the same encryption setting.

I even disabled the WEP and my firewall on the laptop and still nothing. I know this wasn't too smart, but I just wanted to see if I could connect.

I checked that I had the correct ssid and channel set on the wireless profile on the laptop. And since I've connected via other laptops(i.e. one's with wpa2 encryption cards) I know the router is set up and able to connect.


Any light shed on this would be greatly appreciated.

WPA2 is only available on 802.11G.
If the laptop you are using has 802.11B, then no, it will not be able to connect via WPA2.
Although B does support the original WPA

Can anyone explain to me how is it that hotspots are able to have users that are both WEP and WPA2 connected?

Also, if many routers tout that they can handle both 802.11b and 802.11g why do they leave off that the both cannot get on the network if they are not set to the same encryption?

to my knowledge, a router can only have 1 type of encyrption enabled, at any given time.
I don't know how 1 person could connect via WEP and another connect via WPA to the same router, unless the router actually has that capability.

because G is backwards compatible with B. A wireless-B can connect to a wireless G router, and vice-versa. If the router is set to WPA2, then no, it cannot. The wireless technology itself is backwards compatible, the WPA2 encryption isn't.
