Sorry I know this problem probably has been brought up many times. But here I just want to make a total one and collect all the feedbacks from N1 users regarding to the wifi sleep issue with N1.
Let's just make it simple: Every N1 owner PLEASE DO test out the wifi connection when your phone goes to sleep as there are MANY people suffering from this problem all over the world. Especially the later buyers since February this year, almost every phone is potential to this problem.
######################################################
Diagnosis:
1. Set the wifi sleep setting to "never" in the wifi advanced setting menu.
2. Turn on Last.fm app(or Pandora, but Last.fm is most effective and responsive one to test it out), leave the phone on wifi and turn off the phone screen or let it goes to sleep.
3. The symptom is the app will stop streaming shortly afterwards(with Pandora stops maybe after one song, for which I suggest everyone test it for at least 15 minutes). Also most likely you will stop getting any email notification or anything requires data connection. And you might not be able to ping your phone or the ping responses VERY slow as well.
######################################################
######################################################
Background:
This problem was recorded from earliest almost 6,7 months ago and has affected both AT&T and T-Mobile versions(with reports of the same issue on other versions sold outside US). So far, it's suspected that the problem mostly likely lies in the lower level architecture of the phone(either software or hardware) because the problem still exists even after people has replaced the stock ROM with the custom ROM. Another proof is that people get problem with brand new phone and also the replacement phone. Another note is the problem has been found both before FROYO update and after. At this moment, there's no official fix(some Google employee blatantly brushed the issue away and asked N1 users to get over it, check out the link below for original conversation) for this issue except a work around thanks to wifi fixer app developer.
######################################################
This issue is often times neglected by N1 users because usually people don't use the phone on wifi all the time or they simply switch between 3g and wifi. But for people who use wifi a lot or use VOIP, it could be a real deal breaker.
So here I just hope everybody could test your phone out and see if you have this issue or not. Please report how your result turns out in this thread. Also, for further and more detailed discussion and cases, please check this out:
http://www.google.com/support/forum...52&hl=en&fid=01a47ff5b0a92d5200048be07b6cb5c1
You are more than welcome to add your experience to the discussion above so hopefully it can wake google up.

UPDATE:
So Broadcom just released a wifi driver fix several days ago which may solve this issue. According to the record, phones with non-zero MAC address suffer from problem.
The driver has been incorporated into the latest Cyanogenmod(either RC or nightly build). People are reporting it fixes the problem while in some other cases, the problem still exists even after the fix, even for people who's MAC address starts with 00.
Last.fm works fine with the screen off here, always has done. I even turned off mobile data to be sure it's not switching over to that.
This is with the wifi set to sleep with the screen off (ie. the default setting).
i've been using wifi fixer and since i installed it, i haven't had a single wifi disconnect on my home network(it seems to be a network dependent issue as i never have issues on other networks)

yeah, the point here is that many phones have the wifi sleep policy issue(doesn't work).
Indeed, however mine does, so this thread will need both sides of the argument
No problems on my Nexus One, running latest CM 6 nightly build.
I bought it couple months ago from eBay, so I'm not sure which shipment it is from.
Only issue I'm having after upgrading to Froyo is that my phone won't connect to my home network by itself when in range.
I have to go into Wifi Buddy and manually connect. This never happened on 2.1, but magically started after the FRF50 update, and never fixed itself in the next couple of builds.

I have always had this same issue! Maybe its something to do with my home wifi? I am yet to test it on froyo.
I am mostly connected to wifi with no sleep issue.
I have kind of the same issue at home, I recently replaced my wireless router, I never had problems connecting to the old one it would just stop broadcasting constantly but my N1 would always connect automatically. With the new router my N1 keeps saying the connection is disabled and I have to connect manually. This never happens at work, it always connect automatically so it seems to have something to do with the router settings but I have no idea what.
No problems here. Last.FM works fine for me on WiFi when screen is off. I also get notifications. Running FroYo rooted with locked bootloader

i am having the same problem, when i go out of range from my wireless and then back in range, the n1 just says scanning and never re-connects.
that said, using a channel lower than 11 on my router did seem to help with the sleep issue.

sorta, i never had the issue on any network besides my home one
I've also been having the disconnect problem with my N1. Maybe it would help if people whose sleep policy is actually working could post what wifi router/AP/whatever they are using. Also, if possible the first for identifiers of their MAC address. I read on one of the Google posts someone with a MAC address starting with 38:E7 having problems. The MAC for my phone is the same. For what it's worth I'm using a D-Link DIR-655 router and a Speedtouch 716 v5 WL and am experiencing the disconnect on both.
I've had the issue with 2 N1 tested on 3 different routers. I've read that it is related to the low power mode the N1 uses while sleeping not playing nice with routers. Not all N1 show the problem, apparently only the most recent ones. I've called google support and was told google knows about the issue and is working on it, but I am a bit cynical and I'll believe it when I see a fix.
Wifi-fixer fixed my problem only after I disabled Sipdroid which was interfering with it.
Mac adress: 38:E7: D8
I'll post my router model later when I get home.

It's weird because most of the time I don't have this problem. My WiFi stays connected all night long to WiFi. But once in a while it does disconnect and switch to 3g. I think its certain routers, because I didn't have this problem for first 3 months on my old router, now it happens with my new router.
My phone never has trouble reconnecting back to WiFi. Everyday when I come home from work, as I walk up my driveway the phone has already automatically connected to WiFi. I've made sure about this one since I read this problem all over.
I bought my Nexus One directly from Google when it came out for AT&T. It certainly has the wifi issue and it is very annoying. My expectation is that the phone jump on my wifi network when in range as all of my other phones have done. Instead I have to manually engage the phone to get on wifi. SUCKS!
this is the biggest problem for me with my n1.
although the wifi does stay awake, it slows right down..
if i ping my phone, the response time increases when the phone is asleep, but doesnt time out.
if i ftp a file from my laptop to my phone, the speed drops from 1mb/sec to 100kbps/sec when the phone is asleep.
i have found the app "fix my wifi" solves the problem of waking the phone after a few hours of sleep and finding the wifi has failed. if only there was a way of getting the speed to stay the same.
Im having some problems with the wi-fi connection. When it first conects, everything goes ok, but when I start to download anything, the connection just stops responding, even tough it looks like conected. What should I do?
I'm having the same problem and couldn't find the solution, did any solve the problem?
Wifi problem on MS2
After months of researching and suffering the pain I still have not got a full solution for my MS2. My wifi problem is that it connects well, great wifi speed on my home network. But after a couple of minutes there's no more internet access even though it shows that its connected. I chanced upon this link laptopmag.com/review/cell-phones/motorola-droid-2.aspx?page=4 where it had the same problem brought up. It had a solution/fix which I do not want to use though. Further information can be found on the droidforums link on that page. What I have been doing all along is the same as what the guys at laptopmag has been doing, just reconnect whenever internet is down. Irritating yeah, but don't really have any other option..
Hope someone does have a proper solution :X
In addition to the sporadic troubles loading some sites with Flash elements, we had a much more persistent problem maintaining Wi-Fi connectivity. On three different routers, the Droid 2 would connect and then, after a few minutes, would continue reporting that it was connected but stop downloading data. The solution to the problem, once you notice it, is to disconnect from the router then reconnect, but that is a huge hassle.
Our original Droid experienced the same Wi-Fi problem so many times that we eventually gave up and resolved to use 3G only. However, after searching through several Droid forums and finding dozens of posts from other users who experienced the same problem on first-gen Droids and Droid Xs, we found a possible solution that seems to have worked with the Droid 2. After we changed the settings on our 802.11n router from mixed mode to 802.11g only, we did not experience the problem again, though we had to operate all of our computers on the slower 802.11g speed, which is unacceptable.

I installed the BlurLess GB rom and the problem is now gone.
Btw, my router @ home is G only, so the solution posted did not apply for me.
I've had my Transformer for about 2 months now and my WiFi connection has always been reliable and robust, but ever since the last OTA update (8.4.4.11) it's gone flakey. I know the problem is not my wireless router since WiFi was working great before the update and I have lots of other devices that connect without any issues.
At least once or twice a day after resuming from standby, the WiFi icon stays dark and no amount of trying to reconnect will get it back. After a few tries, I can actually watch the checkbox for WiFi settings toggle on and off repeatedly by itself.
I've tried changing the WiFi disconnect policies, closing down apps, and stopping non-critical processes but the only thing that fixes the issue is to power down and restart. WiFi will then work for awhile but eventually goes out again.
Anyone else seeing this?

FWIW - it's also discussed in these 2 threads and is worked around by giving your TF a static IP. Not ideal, I know, but at least it will get y'all working.

That's kewl and all but what if you connect to different AP's during the day. I access through my EVO 4G while at work and then access my home network when I get home. This may or may not work. I'll have to see when I get my TF on Thursday. Thanks for the quick links though.
You can also increase the dhcp lease time in your wireless router, it also works for me.

Download WiFi Analyser, which will show you, which IP data you need for static configuration.

Not exactly the same issue and I already set up static IPs for all the devices (32 of 'em!) on my wireless network long ago.
I did find that one particular app was probably the cause (PCFile Sync) and since replaced it with another having similar functionality, but I still very occasionally lose WiFi and have to reboot.

I've been following this issue since I started having it on the 3.1 update when I unboxed the thing, so I'd really like to understand what issue you found with PCFile Sync, or at least what led you down that road.
Up to this point because of my specific goings on I've been thinking it was more a DHCP/routing issue and not in fact a WiFi/connection issue - i have strong connection before and after whatever the event that shuts things down is, just no traffic.
A little more info here as well - http://forum.xda-developers.com/showthread.php?t=1191792

The behavior I described in my initial post (watching WiFi toggle on and off in settings) seemed to suggest something was blocking or interfering with the normal connection after resuming from standby (I have my WiFi disconnect policy set to turn off WiFi when the display is off).
So I just started closing down apps that had WiFi access and when I killed PCFile Sync (which I use to sync files between the TF and an NAS), the problem went away. I'm now using FolderSync Lite which doesn't seem to cause any issues, although on rare occasions WiFi will still loop for awhile before connecting.
This never happened in HC 3.1 so I think it's a vulnerability in 3.2 under certain conditions ... and those not using a static IP on their LAN are probably seeing something similar happen.
You know, after using my TF after the update, I think what this wifi bug is really just a fix gone wrong. Maybe it's some condition set to turn on wifi only when in use (to save battery life, or allow certain tablets that won't go into deep sleep to go into deep sleep or something like that) but it's set with some super sensitive conditions that make it turn off unless there is an actual request for internet?
My bar goes from blue to grey/white after a minute or something, but I can seem to always access some webpage when I click it from an app. Hmm.

This happens to me with 3.1 randomly, though my policy is set to keep WiFi alive and I never used this PCSync app.
In my opinion the Android Broadcom WiFi card driver is buggy, because the SGS2 with android 2.3.3 has similar problems and also a Broadcom card.
So I guess it has nothing to do with the Android version, but is a buggy WiFi driver. I remember, that I had similar problems with an Intel card in a Toshiba notebook years ago and it was fixed with a driver update.
The question is, who develops the drivers, Google's Android team or Asus & Co? I guess the later? If it are the manufacturers, I find it strange, that Samsung has similar issues.
+ 1 on this very frustrating bug; since upgrade to 3.2 it happens every now and then ; as I did not install any new Apps I assume that this is just a very annoying 3.2 bug...
Anybody with any solution plz?

A german TF owner reported in a german Android forum, that he phoned Asus support about all well known 3.2 issues and they told him, that a firmware fix will be released by OTA next week.
Knock on wood that this is true.
So far ... static IP.

Hey guys, the newest 3.2 update (not the first one but the second one that came out) messed up my Wifi and now I can't connect to it. I've turned off/one my roouter+modem, wifi on tablet, tablet itself, and re-added the network multiple times and nothing seems to work. What happens is that I add the network and it would try to connect and authenticate but then it just retries connecting again and then all the available wifi networks are gone. It's a mess. And it happened a few times where it would finally connect but then no webpage would open after a few minutes and the wifi bars on the bottom right turn from blue to grey. Wtf. How the hell can Samsumg mess up something like that? And no it's not my wifi since it works perfectly fine with alllll of my other devices.
I just had exactly the same problem. 3.2 was working fine for a couple of days for me but now has difficulty connecting and when it does connect doesn't seem to be able to reach the internet. No issues with other devices. Time for a custom ROM?
Had also issues with wifi and the latest stock 3.2. It went away with Task 6.1 and probably the other custom rom also.
And now it is all working again.
Strange but worrying.......
On the contrary the wifi is better now with me. I used to have wifi issues after the TW update. The first days with stock Android I dont remember a single day dropping my wifi connection, but after TW update I sometimes picked my Tab to see "no internet connection". After 3.2 update it is just always on. I am quite happy with this update. If I ever see a drop in connection it is %100 router related which sometimes confuses and tries to assign the same the IP address to 2 different devices.
Hi again, since my last problem, that my galaxy tab did not wanted to turn on, I got a refund and waited until the machine came to my country..... months later, I could buy it at walmart, and all went fine, I got a 16GB wi-fi/3G tablet and went to a friend's house to use it, wi-fi worked well, then I bought a router, and installed it in one of my houses, and all went fine, I could even use it 20m away, then I installed it in my actual house and first it came ok, I could connect it, and worked for several days, went away and used the 3G internet, and came back and used the wi-fi because it has better speed, and it started to don't work, so I reseted the router like 3 times, each time it didn't work, then I contacted a friend of mine that works installing routers for companies, and he configured mine so it had a better security and values he knows that would work better, and indeed the problem was solved... for a couple of days... now, it says connected and it does not charge the pages, or if I "forget" the network, and charge it again, internet works but it loads pages partially it does not load them completely. On my phone and laptop the internet always works, in the tablet that is the problem... so what could it be, or how could I fix it?
PD: this is really strange, because normally it happens either when I shut down the router (because it is right besides my bed and the computer (big desktop) makes noise) or when I leave the tablet in stanby for a day or so, I write this because now I just restarted the tab and internet worked as if anything had happened...
I was recently having problems with wifi also. Mine was connected to my network but I couldn't get on the internet. This happened after a few weeks of ownership with no issues. I found this article and it pertains to my issue, not sure if it will help you though. You do need a rooted device to be able to do this "fix". It worked for me though.
http://steve-shaffer.com/2011/02/samsung-galaxy-tab-wifi/
Ok thanks so to root it, is the method suggested in the article safe, or what could I loose with that procedure? meaning, do you know a trustfull procedure I could follow?
I had the same problem too recently...works well at my friend's place but not with my router...it seems that the tab works well with static ip and not with dynamic ip address with we people usually have...
Oh , just read that link...i was about to say the same...
There s another way...
Without root,
reset your router
go to your wifi settings
go to wifi channel
set the channel to 11 (6 or 4 works too)
these channels tend to workout the problem i heard...worth a try right...
You can try this before you root
