Drops internet connections FVS318N with the newest firmware

Well after updating to the newest firmware.  This has turned in to a nightmare.   I can't remember how long I've had it but I've always had to reboot it maybe once or twice a week for losing the WIFI now after the update firmware now it losing the internet connection.   I have no problem rebooting it but it went from once or twice a week to 3 or 4 times a day.  So I down graded to much earlier version firmware still does the something so basically this thing is junk now.   I don't mind rebooting every now and then but NOT every couple of hours to hell with that so I broke out my old D-Link 8 port WIFI been running with out a glitch for 2 days its a 10/100 so it's a little slower but right now I'm willing to sacrifice speed for reliability im tired of getting up and go in to other room and reboot just so I can finish sending email or receiving it give me a break.   This can't be this difficult to make it just work.   I have a simple configuration I use it for all the computers and for mobile devices I never have more than 2 mobile devices on it at once and maybe 2 computers on at once so why is this keep dropping the internet its behind a AT&T uverse residential gateway and the WIFI or internet never goes down   I just want the netgear to work like the AT&T gateway works flawless...    any ideas I'll be more than happy to try.
