If the network is hidden,
you may have typed the wrong SSID (or if there??™s more than one
hidden network in range, you may have selected the wrong one).
If you ask Windows to diagnose the problem, it??™ll probably suggest a
weak signal, but that??™s unlikely if the network is showing up in your list
with at least two signal-strength bars. More likely, it??™s not a real network
(perhaps someone else??™s laptop errantly set to accept incoming
connections), or it??™s using MAC address filtering, as described in ???Lock
Out Unauthorized PCs,??? next.
Non-broadcasting network won??™t show up. If you see an entry named
Unnamed Network, select it, click Connect, and fill out the details of
the hidden network. But if you??™ve already set up this network and it still
isn??™t showing up, then you??™ve encountered a nasty little problem in
Windows Vista. See ???Sniff Out WiFi Hotspots,??? earlier in this chapter,
for help dealing with networks that have the SSID broadcast feature
turned off.

Broadcasting (non-hidden) network won??™t show up. If you??™re mixing old
and new equipment, make sure none of it is set to work only with its
own kind. For instance, many 802.11g routers have a setting that either
permits them to talk to older 802.11b devices, or restricts them so only
g-class devices can connect.
