I have bt total broadband + bt home hub and have a wireless connection.
IF i install a second pc , also wireless ,but do i need to install the bt broadband disk as well on the second pc....if i dont need to install it again do i have to get a seperate anti virus protection on the second pc or can you still download the one you get from bt which is on this one now to the second pc as well...........i do know i will need another wireless adapter, but get confused as to how it works if you don't need to install the disk again

your network will look like

Code:

btModem---wirelessRouter---- wireless connections to systems

the make and model numbers of the modem would be nice to have.
you mentioned a HUB; need that make and model too. IF it is a true HUB,
then we may have a problem; you need DHCP support and a hub does not provide it.
Normally we use a ROUTER not a hub or switch.

If your btModem is the wireless device, then it likely has the router support too.

So post back the device info and we'll proceed from there.

yes i am using a wireless router , and a wireless conection but was thinking of installing a second pc to the wireless router, but was not sure if i had to install the bt network software on the second pc

your BT modem/router is likely to have BOTH an Ethernet and USB connection.

As long as you only use the wired Ethernet slots and/or wireless connections,
the the BT CD is actually useless. The CD contains the USB driver which is not
being used

The wired NICs use the Ethernet drivers and your WiFi adapters use their own drivers.

UPDATE all devices to the latest+greatest support if you need WPA encryption
as it tends to be vendor specific
