Wireless network very strong but rarely connects

[dobspoon]

Seems very odd - sometimes the network is accessible, sometimes not. Always shows as an 'excellent' signal, WPA key is definitely right (else it wouldn't connect, right?) and ipod picks up the network perfectly. Have moved devices closer to each other, changed channels, removed obstacles - nothing seems to fix it. Where do I start?

Thanks in advance for any help.

Just logging on as can't sleep - rather annoyingly in the process of being made redundant! As such, my problem is more acute - I'm going to need my internet connection at home. I'd really appreciate some help.

I'm currently on my work machine which is having no problem at all accessing the network. The desktop alongside displays 'unable to connect to network'. Clearly it's something to do with the hardware on my desktop as I'm sitting at the same desk where the desktop is failing to pick up the signal.

Saying that, it does tend to find the network after sitting around for a while or after multiple attempts at connection (changing nothing). When this happens we're leaving the machine on all day! That's not ideal obviously - it's a bit noisy.

Where should I start? Please help.
