Symptom: Wifi constantly connects (obtains a valid IP address) and disconnects to Netgear WNDR3700 router with WPA2-PSK [AES] security enabled.
Reproducible: Yes.
Steps to troubleshoot: Reset the router, adjusted the speed and security settings on the router, adjusted the channel on the router multiple times, stood right next to the router, erased/reconfigured network in settings on phone, factory reset phone multiple times, exchanged phone once.
No other devices that connect to this router display the above-mentioned symptom. No drops whatsoever when using the following devices that also connect to the same router:
Sony Playstation 3
PC Computer running Windows 7 and Ubuntu 10.10.
MacMini running OS X 10.6.5
lenovo ThinkPad T61 running Ubuntu 10.04
iPhone 3GS, iPhone 4, iPhone
Kindle 3
Again, none of the above drop their connections. At all.
After digging through some forums, I’ve found that this is a fairly widespread issue.
Motorola even knows of this issue, offering the following “solution”:
“Thanks for reaching out to Motorola. I have reviewed your e-mail and I am ready to help. I apologize for any issues that you are experiencing at this time. I would recommend you to reduce the security setting on the router to WEP or WPA or even completely disable it. “

Things that are not an option for me:
- Getting a new router.
- Reducing the security settings on my existing router.
- Never using the phone’s built-in wifi.
- Waiting for Motorola or Verizon to send a fix.
Things that are an option for me:
- Returning my phone for a full refund.
- (If the above is not provided) Paying the early termination fee, vowing to never use a Motorola product or Verizon service ever again, and tell as many people who will listen about my horrid “Droid Doesn’t” experience.
Solved! Go to Correct Answer

DroidX WiFi connection problem solved for Netgear WPN824v3.

WMM is an enhancement on this Netgear router to prioritize media streams over other requiests. Switching this option off did not affect 3 laptops in my house (neither video streams nor on-line games). With WMM turned on, the only way for DroidX to connect was to set router to "open" mode.

Mine was fine for the first couple months. It's possible that this may be an issue between the wireless chipset in this specific router (which no other devices seem to have a problem with) and the Droid 2 wifi chip. Forums I've seen seem to confirm this, as only people w/ certain routers are affected. Moreover, the symptoms only present themselves when WPA2-PSK encryption is enforced on the router.
The wifi chip in the phone also seems to need to "warm up" before it starts freaking out. For instance, when I wake up in the morning, all is well. It's only after about an hour of wifi use that it goes into the connect/disconnect cycle and I'm eff'd for the rest of the day.
Here's some other interesting info:
After installing the OSMonitor app, I decided to take a look at what the system logs are saying...
Every few seconds, the following messages appear in the "Message" tab in OSMonitor:
12/09/2010 07:11:34 [INFORMATION]
TIWLAN: 2802.711978:
TrafficMonitor_ChangeDownTimerStatus: Going to
active, set wake_lock!!
Which I suspect is supposed to keep the wifi awake but, for some reason, is not. Connect/disconnect events can also be seen in the logs, between the constant posting of the above "TIWLAN" event.

OK, so.. running adb logcat (source: http://developer.android.com/guide/developing/tools/adb.html ) for a couple minutes, through multiple wifi flaps, I've found a couple interesting things:
"tiwlan is useless"
Why yes, adb logcat, it certainly is...
Here's a full circle -- from connected to disconnect:
