I have had a few problems with wireless signal and my PowerBook. I use a Netgear 54Mbps wireless router on my 2.2Mb broadband and discovered at one end of my 1.5metre desk I had an "ok" signal, but at the other where it is more convenient I had next to no signal! This was highly annoying. I am running Tiger and was looking forward to the 10.4.2 update which promised better wireless networking, as mine had been suffering from the drop outs and other problems described. To my horror 10.4.2 made it worse. Now I can be right next to my router and my PowerBook wil drop the signal without warning and insist there is no signal in range.
Highly annoyed I changed the channel of my wireless network (on router) to a lower one (as I was on a high channel) and the signal seems to have improved 100%. I no longer get any of the strange drop outs and my PowerBooks so far always tells me the wireless network is there, at least, even if it cannot connect to it!
In the vast majority of cases it is the configuration and positioning of the router that affects the reliability of a wireless network.
1) Ensure that your router's firmware is up to date.
2) Position your router correctly (not on top of tall cupboards or next to windows or mirrors).
3) Adjust the routers aerials bearing in mind that the best reception will be within a large ring doughnut shape area around the aerials. The size of the doughnut will be relative to the gain of your routers aerials. In many cases it is possible to obtain aerials that provide a higher gain.
If you continue to have problems try moving your router, adjusting the aerials, changing the channel, etc... Also make sure that you don't have your router or PowerBook next to a mobile phone, cordless phone or other radio/microwave device. If you are unsure about what might be causing interference, try switching off all major electrical equipment in the house and then turning them back on one by one until you find the culprit.
Unless you are very unlucky and live in an area with very high interference levels you should be able to get a good wireless network working in any reasonably sized house.
