Accessing alternative wifi when not asked for password
For reasons I won't go into, the place I am currently working has a number of wifi sites and what works in one place, won't in another. But when I get a list of other wifi sites and select the relevant one, I am not asked for the password and am told "cannot connect". The same issue applies on my iPad.
I don't want to hit "forget" as there are times when that one is needed.
How do get the phone to give me the password entry "page" for alternate wifi sites?
I am using an Iphone 3gs and an iPad 2.
Thanks
