I have two DX's, mine and my wifes. We switched over from having iPhones and ATT. I've read a number of forums and a lot of people are having issues with wifi. I've read a number of variants on how some people having gotten a stable connection. We, however, have not. Some say it has to do with AES or TKIP, WPA or WPA2, or for people with 802.11n routers disabling N, some say it's simply turning security off. I've try everything expect disable security, and I don't plan on doing that. If it will not function with security it's of little use.
I have a D-Link DIR-825, which I've had very good luck with other devices (one of the more stable routers I've owned). On a daily bases it has iPhones, Macbook Pro, Dell Laptop, iMac and various other wifi connections running through it all with no issues.
When I connect the DX's, they connect quickly and are good for about 2 minutes. Without notice, and while the wifi symbol at the top still showing connected, things just stop. On occasion I'll see the 3G symbol pop up and then go away, but nothing will work until I disable the wifi and it switches back to 3G.
I noticed this in the logs of the DIR-825 shortly after the DX's connect:
2.4GHz Band Wifi: Wireless system with MAC address XXXXXXXXXXXX disconnected for reason: Received Deauthentication
I can re-enable wifi and it works for another minute or two and then nothing.
I've read 'rumors' that this may be fixed in the upcoming 2.2 release, but I would like to know for sure. I'm still within my 30 day trial and I'm getting nervous not hearing anything from Motorola or Verizon on this issue.
Thanks
