this is a very common thing that some engineers do while setting up a wifi connection
They are just too (whatever) to do such thing
This thing totally spoils the meaning of a wifi hotspot !
it allows only 1 device to connect at a time
i just know its some sort of dial up typo thing ...
You need to connect to your wifi access point then dial some number with password !
as far as i know it involves some entry of username and password for your modem to dial it up for you automatically
If you can just share the modem name !
