When you attempted to updated FW, was this process followed?
FW Update ProcessLink>
Wireless Installation ConsiderationsWhat wireless modes are you using? Under Setup/Wireless/Manual.
Try single mode G or N or mixed G and N?
Channel Width set for Auto 20/40Mhz or try 20Mhz only.
Try setting a manual channel to a open or unused channel. 1, 6 or 11. 11 for single mode N if the channel is clear.
What security mode are you using? Preferred security is WPA-Personal. WPA2/AES Only. Some WiFi adapters don't support AES, so you might want to try TPIK only or Auto. My iPhone 4S's work well on AES only.What wireless devices do you have connected?
Any cordless house phones?
Any other WiFi routers in the area? Link> Use InSSIDer to find out. How many?Turn off WISH, and WPS under Advanced.
Try turning off Short GI, WLAN Partition,and Extra Wireless Protection if you have it. Under Advanced/Advanced Wireless.

WMM Enable Under Advanced/Advanced Wireless.
I just wanted to let you know that after I switched to 2.10NA I had problem with the internet. I would try to go to a web page and receive 'Cannot access web page'. After you hit the diagnostic tab it would do its check and come back as everything is fine. Then you could access the web page. I was having problems on all the PC's and laptops in the house. The computers are running Win 7 x64, Vista x64, Win 8 Pro x64, Ubuntu x86, and Mint Cinnamon x64.
After switching to 2.10NA, the iPad would finally stay connected to the router. But my daughters started having problems with their iPhone 4S staying connected. I tried switching to 2.10NA because the iPad would never stay connected. Sometimes it would stay connected for a couple minutes and at other times a couple sec. I was running 2.00 firmware before.
I just switched back to 2.07NA to give it a try because I found this forum. If I should experience any more problems I will leave some feedback.
