[UPDATE]Official Nexus one Wifi issue thread(every N1 owner should read)

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.

[Q] serious wifi issue!!!

After spending time searching the net for a solution i couldnt find anything as it seems my problem is unique. The issue is when i connect to my router through wifi every thing goes fine however when i go out of range or disconnect for a while and try to reconnect i get a message "Connecting..." then "Disconnected" and it never connects until I restart the router. The issue was worse where it connects for 1 time but the next time it does not detect the router, this was resolved by setting the wifi channel from auto to channel 6. But now i am stuck with this issue that has no solution. I have tried everything from static IPs to mac filtering, i also wanted to update the router (gigaset 504 agu) firmware but could find it. I am currently using x10 with firmware 026 -global. If anyone has a solution plz share it as this problem is really annoying

I have the same problem with my netgear router, it is very annoying...I think this a known issue with some android phones and certain routers.

Its seems no one has a solution, I guess we need to wait for 2.1 and see if the update resolves this issue

Well you could provide internet connection to your phone via your computer. What OS do you have and what kind of internet connection (wired/wireless) does your computer use?

Not that I've ever tried or used it seen as I don't have issues but perhaps this might miracally work..

It's an android problem. I have this with my x10 and froyo nexus one. The only solution is to quick toggle wifi on/off in the power management widget. I've seen this happen on a Linksys wrt54g and wrt120n. Same with a D-Link dir655m and dgl-4300. If you are really unlucky like me. Having wifi and bluetooth on at the same time with this problem will cause your phone to either freeze or reboot on its own.

I get this with some routers, what works for me is. Data /3G, wifi off, 3g on, wifi on. I use switch pro to quickly configure the toggles.

just to be clear...do you mean you switch off data/mms then wifi off...then switch on data/mms and wifi.

thanx guys for the reply, but none of the mentioned solutions worked

Wifi Possibly broken

HI
last night i rooted my phone using the exploid x10 root apk, at first it worked fine and so i left is plugged in over night to transfer all my music onto my new sd card
but this morning it seems the wifi has broken
it connects to the network but will not send or receive data, so the browser says no connection, so does the market etc
i have reflashed its software 3 times even downgraded back to the R1, still no luck, its not even rooted and its broken
any1 had the same issue? i have searched the forum but the ppl with the sam issue have not been helped. please i dont want to spend $$ to get it fixed i have no job

Hi.
No problem with the wifi so far.This is strange.
Do you have warranty?
Sound stupid but did you try to reset your router?
If nothing is working you should go to the service.

yea i messed around with wifi router, nothing, i can browse the net on 3g wich is odd, but 3g is expensive so that cnt be the solution. bluetooth and 3g work obv but the wifi cannot connect itl connect to the wirelss just NO datac exchange?

There is someone with the same kind of problem but on an EVO 4g, but i really do not understand what they reply's mean. Maybe you do?
http://forum.xda-developers.com/showthread.php?t=800910
tried to search on google and came across a LOT of people having this same issue, on laptops, iphones, ipads, which lead to the conclusion that it may not be a wifi failure?

well it cant be a complete wifi failure kuz i used the dev menu and it says wlam enabled and scanning just no connection

thanks

i managed to fix it, it wasnt my device as such it was my router, too so i fiddled around with both mainly giving my x10 a static ip and bam it worked, cheers!!

I too have a wifi problem, but it is quiet a different one and i have no idea how to solve it.
when I connect to wifi at home my router reboots, but there is no such problem when i connect to my office.
I tried reseting the router at home and still no use, once it got connected and when i started a download from the market the router again rebooted.
How can i solve this????

And your router obviously operates all 3 standards at once

Wifi won't stay connected (not D-Link problem)

My phone has problems staying connected to wifi. It's often disconnected and has to reconnect when I wake my phone up (even though it's set to not turn off during sleep) and it'll disconnect and reconnect sometimes even when the phone is awake. I've read about people having problems with D-Link routers, but none of my routers are D-Link. The problem seems to have improved a lot after I flashed my modem to the MDL modem, but it still comes up. Does anyone have any solutions or would anyone know what could be causing this? I'm currently running the Wicked rom but I had this problem even when my phone was completely stock. Has anyone had this problem go away after switching to an AOSP-based rom?

I still have this problem, it disconnects and reconnects minutes later. I am on stock, stock kernel and rooted. could it be a root problem?

It can't be a root problem because I had this problem even when the phone was completely stock. I'm wondering if it's a TW problem, which is why I asked if anyone still had this problem after switching to AOSP (the Wicked rom I'm running now is TW).

If it were me, I would try a different modem, but thats just me.

Is there a thread with the available modems?

Just because it isn't a DLINK wireless ap doesn't mean you won't issues. All the consumer-grade wireless routers/ap's share a narrow range of chipsets made by broadcom, atheros, etc.. So, the brand has nothing to do with it.
I would suggest getting a logcat if you can or try another wireless ap somewhere else. I've got a TPLINK wireless router with OpenWRT flashed, runs flawless.

I never said that only D-Link routers have problems. There's a well-known issue with D-Link routers so I wanted to state up front that I don't have any D-Link routers in case anyone wanted to suggest that it could be the cause.

He said the option was only available while originally connecting and setting up the connection for the first time. Maybe you can try to delete the wifi connection all together and then let it re-detect and go through the set up process again...if that is an option.

My phone was doing this on my friends router but not on my home router. He searched google & found something stating that the S4 dont like routers with AES encryption for the security. He changed his router security to TKIP+AES encryption & the next time I was there wi-fi stayed connected with no constant reconnect problems. Buuuut, my home router security is just AES & I have no issues connecting to it, yet at least. Dont know if this will help anybody else out but its worth a shot to play with your routers security settings.

I thought I had an issue with my I337 S4 do the same thing.turns out my phone was just bouncing around trying to connect to 6 other open WiFi signals I've used

So just to give an update, I tried installing another router in my house as an access point and the phone has no problems staying connected to it, so there's definitely something that the phone doesn't like about the other routers that I'm running. I'm reluctant to say that there's anything "wrong" with my old routers because no other device had a problem staying connected, but if anyone else experiences the same problem, changing routers/APs could work. Fwiw, my old routers had Broadcom chipsets while the new one has an Atheros chipset. I'm going to try updating the firmware for the old routers to see if it helps (I run DD-WRT and Tomato on all of my routers).

WPA/WPA2 decreases the bandwidth of the router. WPA2 will support a full 300Mbps link state. So yea, they are different, but it may not fix it.
I have a Cisco EA6500, so I'm connected to the AC 5Ghz band, and it works flawlessly. WPA2 Personal

My bad on typing WAP instead of WPA.
Doesn't sound like fully opening up the bandwidth will fix it.
Has something to do with how the phone manages the encryption keys?

[SOLVED] Connected to Wifi but no internet connectivity

I was having Wifi issues on the 6P. Connected to home wifi but no internet. The thing is, the wifi would still work randomly. It's possible that it works most of the time but as soon as I go out somewhere and out of the home wifi range, it sometimes messes up when it tries to reconnect to the network.
And yes, I realize it may not be a phone issue but maybe the router (Asus N66U with Tomato firmware).
/edit - well, I spoke too soon and I guess it's not the static IP causing the wifi issues.
It turns out it was a firewall app called AFWall+

Might want to update the title then. Although I do have that issue where when I get home i have to turn off/on wifi on my phone to get a connection.

I remembered I had set a static IP for the 6P earlier in the week so I thought I'd try to see if that was the culprit. The moment I disabled the static IP, I got internet connectivity on the 6P again. The thing is, the wifi did work earlier in the day and even the week, even with the static IP. It's possible that it works most of the time but as soon as I go out somewhere and out of the home wifi range, it sometimes messes up when it tries to reconnect to the network.

It's hard to say. This problem seems to be random. I haven't experienced it today. The only change I've made is update Cataclysm and ElementalX to the newest versions after installing the latest Android security updates. I can't guarantee I won't experience the problem again since it was happening on and off before.
No amount of disabling wifi and restarting my 6P would get internet connectivity back when the problem is happening. It just seems to start working again randomly. Is that what happens to you too?

I can't really explain it. It says I am connected to WiFi, and speedtest still works along with web browsing most of the time. But the main thing that doesn't work is my google account syncing (so emails wont appear, or delete from ym account when I do so in the app) as well as the play store not downloading or updating apps. I keep seeing issues with 5ghz, so I am gonna try connecting to my 2.4ghz as well as setting the wifi to 2.4 only, as of right now it is working. But its like you said random, and when it does happen restarting is no help. I also just set my phone to use a static ip as I heard that helped some people. I just found it weird that you have the same router and had issues.
Im on Pure Nexus with ElementalX latest update, don't have the latest security patch though.
Its only my Nexus 6p, and it seems I have no issues when I am on my girlfriends wifi. SO I am hoping the 2.4 and static IP solve it, however that sucks cause I want to use my 5ghz, as there are less devices and I get a more solid connection.

I found out it wasn't a problem with the phone or 6.0.1 at all. It was due to a firewall app called AFWall+. I figured it out when I realized internet connectivity would return when I disabled it.
Now, you might think that the app should have been one of the more obvious causes. That's true... but I had it set to Blacklist mode to only block certain apps. Internet wasn't working system wide and it only occurred on Wifi whereas LTE worked fine. So, uninstalling it seems to have fixed the problem and it hasn't happened since. Perhaps it's an issue with systemless root.
