how to get another notebook to use the same wireless connection?

You can have more than one laptop use the same wireless internet connection.
If you are talking about ad-hoc that is a different setup from the
"infrastructure".

Most residential wireless routers use a subnet mask of 255.255.255.0, which
leaves 8 bits for host numbers. One of the host numbers (0) is for the
subnet address, one (255) is for the subnet (directed) broadcast address,
and one is for the router. That leaves 253 IP addresses for other hosts
(laptops/PCs).

However, the number of IP addresses is only one limitation imposed by the
router. Another is the router's and AP's memory for tables. The AP (in the
wireless router) needs a station table, and the router needs an ARP table.
It's unlikely that a residential (as opposed to enterprise-class, like
Cisco) wireless router supports 253 hosts.

Another limitation is imposed by the bandwidth and the fact that wireless
uses shared bandwidth, not switched. Also, some bandwidth is wasted by the
Collision Avoidance scheme compared to a wired network's Collision Detection
scheme. And when a wireless network does fall back on Collision Detection,
it's not as clean as in a wired network. This all results in a practical
limit well below 253 hosts. I've seen a rule of thumb to install an AP for
every 20 users using 802.11b; I would expect that number to be increased for
802.11g.

exelent info,
thanks.

You need to read the documentation on a few of them....

This is definitely a much more problematic limitation. Not likely to be
much of an issue for domestic installs tho.
