wireless network comes and goes

First of all you need to acknowledge that wireless channels "bleed" over each other. This means that when you occupy a channel, for instance channel 6, in the wireless band it will span over roughly 40 Hz. That is enough to span two channels each way so that the signal is causing interference on all channels from 4 to 8.
So in conclusion: If you are using channel 7 and your next door neighbour is using channel 8 then it is signal interference causing your problem and you will need to change to another channel.

Use netstumbler to see which channels are occupied close to you.
Then select the channel most far away from the occupied ones.

Also be aware that WiFi uses the 2.4GHz band that it shares with a lot of other applications. Keep both access point and wifi adapter in laptop far away from other wireless devices such as chordless phone basestations and wireless mouse receivers. Also keep them at least 30cm away from screen and power adapters (including the ones used at the bottom of for instance halogen lamps - they are nasty for a wifi signal).

Many routers / accespoints have problems with accessing it frow wifi, so when you setup youre wifi device use a cable connection.

It was actually a 3rd problem...my modem was using 192.168.1.1 and so was my router. I set the router to look for 192.168.0.1 and then there was no conflict. Thanks for helping though. send svar and Ill send you both points

ah yeah, using different ip networks on each side is a good idea when going through a router =)
thanks for points
