This is the exact one I have that has been giving me Sh1t since the day I got it. There are days it will go on all day with no problem and then there are days the pos keeps booting me off the internet and I have to reset it and my dsl modem. It boots my kids off all day on the wireless, on and off all the time, their computers are 15 ft away from me and they are lucky to get 1 yellow bar if they get a signal at all and then its always on off on off. Then at times when my wife turns her computer on, wired, it shuts the entire network down and I have to reboot both the Network and the DSL modem to get it all back on. And then there are just times your surfing the internet and then whamo your off having to reboot again. It has pissed me off for the last time and I have a Linksys unit coming and cannot wait to pitch this piece of crap.
And yes it is updated to the latest firmware and have always updated it to what ever new one comes out when it comes out and always check every week. I have called tech support (you get it for I think 60 days, after that you have to pay) and they were no help, I had it, my kids had it playing online games at nick.com and be in the middle of one and be off, then 3 seconds later be on then 2 seconds later be off again. 15 feet away and getting hardly any signal at all, no walls, NO obstructions, one big ass open room, and Im done with it finally.
