I have read many articles about safeguarding of wireless connections.
Yet I have some simple questions that I don't seem to be able to find answers to.
My notebook is used primarily together with an adsl modem/router/accesspoint that supports both WPA as well as WEP. The notebook does also support WPA as well as WEP.
If I set the same WPA (or WEP) key in both devices, it will probably work OK.
However, I sometimes use the same notebook in two other locations, which only support WEP, but so far have no encryption installed.
If I would try to use my notebook, now with encryption installed, in these unprotected other environments (routers/accesspoints), would it be able to communicate with these unprotected devices?
Or should (the same?) key also be installed in these, sofar, unprotected devices?
And if so, does that immediately create the need to install (the same?) encryption keys in all clients that are normaly used in these other environments, with these previously unprotected accesspoints?
And how will a client, with encryption installed, operate together with a public accesspoint (hotspot)?
