This may not fix the problem but it can help you to understand. Android is a Linux based OS and soho routers (Netgear, Linksys, etc) have some issues with devices using Linux as the OS. The symptom: the router kicks out your device; then the phone has to renegotiate the connection which means that it needs to get an IP address. The problem is sometimes (in my experience) with the renegotiation handle in some Linux drivers , ( so it is also an issue in your phone) . What happen is that the router and phone cannot negotiate again.
How do you know if that is your problem? Simply disable the wireless network in your phone, then restart (do not reset) your wireless router by disconnecting from the electric outlet for a couple of minutes. The router should forget that it previously had your phone in its internal tables. If you phone can connect again with no problem, now you know that is the issue. But don't get too happy because the phone will have the problem again a few hours later.
If you are curious, you can also check the network status of your wireless router. You may notice that the table has information about iphones, windows or Macintosh machines addresses assignments, but Android no trace that it is connected to the network (from the router perspective)
In some of cases I resolved the issue by assigning a static IP address to the phone. You can do that by going to the network settings and configuring it there. Wireless & Networks --> Wi-Fi Settings then look for advanced settings IP settings. There you can configure your address, gateway, and netmask and DNS. But remember than before doing that you should know what local network configuration you have in your network. You also have to dedicate a range in your router local IP address pool for that assignment, so the router does not give that same address to another device (and then you'll have two problems with other device disconnecting)
I've seen this problem in several HTC models,and my Atrix 2 and my Linux laptops; and it only happens with old wireless routers. My windows machine never had issues with the old routers. Maybe a software update in the router will solve the issue (it did not in my case). I have not problems with a newer (but enterprise) wireless router.
I hope this helps you and others.

It's wrong to suggest "fixing" the ap/router or hardcoding network settings as the solution especially when these symptoms follow you everywhere you go. I might get away with that at home, but at work, no.
I have this same issue and it only affects my newly purchased atrix 2, my atrix 4g never had these issues.
With all the wifi/data settings configured to never turn off data services or put the wifi antenna to sleep, the thing should just stay on and connected until I turn off the antenna myself.
When the antenna is on and connected, there's no issues there, I get a good IP and all the appropriate DHCP settings and data serivces work fine so that suggests that the hardware and the software necessary for network negotiation is good. The problem to me seems to be the software on the device deciding on its own when to disable data services and even turn off my wifi antenna when IT thinks its appropriate.
Wether it's the base software or something that I installed is at fault is not important. I just want to know that something can be done to fix this issue. Times like this I wish there was a way to just have some diagnostics software that I can turn on to capture the events that lead to my wifi antenna getting turned off.

My WiFi would turn off every time the phone went into stand-by mode, despite the never sleep setting. I read somewhere to change the battery mode. The "Maximum battery saver" setting was disconnecting WiFi each time. Since changing to "Performance mode", my WiFi has stayed connected without a problem. (Settings - Battery & data manager - Battery Mode)
Hope this helps someone!

I am still using 2.3.5 and it appears to be working fine on this version with the changed battery mode settings.

I reverted my device back to 2.3.5 and the wifi on/off issues went away. Some of the other problems listed here, http://forum.xda-developers.com/showthread.php?t=1423557, did not.
Over the weekend I exchanged my A2 for the SGS2.

Interesting... since the 2.3.6 update for the Atrix 4G "broke" its wifi. 2.3.4 on the Atrix 4G had a working wi-fi/data connection and since they sent out 2.3.6, numerous people are reporting problems. Sounds like there's something in 2.3.6 that both versions of the Atrix don't like.

My daughter's HTC Inspire was stolen at college. As a replacement we got the Atrix 2. We purchased another for my other daughter, so we have two now. The Inspire was having data usage around 80-90 MB because the WiFi access was working well. Once we shipped the Atrix 2 off to college and got it going the trouble started. The Artrix 2 has data usage in the mb range during the night while it is not being used. In two weeks the phone has used 370 MB. The data usage doesn't both me, but it falls of the wireless network and thus causes the 4G network be hit causing overage charges. We have called Motorola and AT&T and it is still doing it. My daughter took it into an AT&T store and 4 people looked at it and verified everything was set correctly. We have put on the data saver (should not access any data in sleep mode) and still the phone access data updates in the middle of the night. The other phone is doing the same thing, but the usage has been in the KB range so that phone has used 7 MB in the same time. Another problem occurred with the replacement phone as a crack has developed in the screen (no it wasn't dropped). No one will take it back now as it has physical damage. I had to upgrade the data plan on the replacement phone until we can figure out what to do. This phone has been used for about 2 1/2 weeks and was purchased Feb 20. The AT&T store people said there is a bug in the android causing it to fall off WiFi in sleep mode. I am not sure how to fix it. Our router is older and we have little control over the routers at school. Any suggestions would be wonderful!

As absurd as this may sound, when I have lost my Wi-Fi connection at home on my Atrix-2 my Wi-Fi settings on phone show connected but my 'bars' on phone showing Wi-Fi signal are grayed out. I have to go to phone settings and turn Wi-Fi 'off'. Then turn Wi-Fi back 'on' again and bang. Phone and router talk again. For how long? I do not sit there with a watch to find out. I can only hope that phone is not transferring data from tower during Wi-Fi down time, thus eating up my data plan. Is this a plot by AT&T? One can only wonder. Having your phone drop Wi-Fi connection while you are in your own home using an AT&T supplied wireless N router is suspicious at best. This is not the first time I have had problems with an Atrix-2 and AT&T supplied wireless router. My last phone and router would not communicate at all. Any attempt to connect phone to router would re-boot router and kick all other devices (PCs, etc.) off the network. Finally got a new phone, and... after many threats to change providers, a new wireless N router. All was well until the new Android OS update. Now I have to watch my 'bars' (blue or gray) and change Wi-Fi settings accordingly. This is a crock!! I expect to see 'blue' bars showing Wi-Fi connectivity anytime while I am at home on an AT&T provided wireless network. Loosing my Wi-Fi connection 'here' is not an option and not acceptible. Using my 'away from home' data plan due to the ineptness of AT&T or 'planned subterfuge' is not acceptible. This may be my last contract with AT&T.

I too got the WiFi connection loop issue, and mine was a simple fix: Simply downloaded an app called KeepWiFi, and the connection now stays constant!
