Wifi help needed!

For the past month I've been using a Netgear DGND3300 ADSL router. Suddenly today I'm having huge wifi problems. My desktop and my dads desktop both using an Edimax EW-7728In cards connect without a problem. However, nothing else will. A dell laptop, hp laptop, iphone 4, iphone 3g and ipod touch all fail to connect. The laptops momentarily appear to show a connection, but then when you open the browser it suddenly flashes up "limited connectivity" and then disconnects. The iOS devices all just say "Failed to join network". This is all despite showing a full signal.

The router is set to "up to 300 mbps @ 2.4ghz". I've tried rebooting the router, restoring factory settings, reflashing the firmware, disabling WPS, changing wifi channel, changing to "up to 145mbps @ 2.4ghz". I then went out this afternoon believing the router to be faulty to get it exchanged only to have the exact same problems with the replacement. wtf is going on???

is it running on wireless b/g/n mixed mode?

As far as I can tell yes. N channel is currently set to 11. G channel is greyed out

This is even more strange. I went out to go the the toilet, came back and the damn things seems to be working fine! Only explanation I can think of is local interference. Strange how the desktop machines didn't seem affected tho.

Wonders of Wireless, I avoid it like the Plague

Never been too keen on it myself. I only use it because my parents don't want more cables throughout the house. It's bad enough already with our tv distribution system. When I get my own place I'm sticking to ethernet

Well it was working fine last night. Today it's just the same. One second I get a full signal, the next the connection drops and I can't reconnect

Well, I've got no idea what's going on. Came in from work and nothing would connect via wifi at all.

I installed inSSIDer to check the signals which appeared strong

My desktop, laptop, and iPhone 4 would all see the network but on attempting to join it it just said "Unable to join network". I then dug out my old Netgear DG834G router and everything connects perfectly and the signal strength in inSSIDer is virtually identical
