Just a heads up, I installed the cyanogen 7/25 nightly build but I still have the same wifi problem. My particular problem is that wifi loses connection when my nexus goes to sleep.

I'm currently using the wifi fixer app on the second nexus fix. While this doesn't prevent the problem, it helps by resetting your wifi whenever it disconnects.
[Nexus One General] G3f:
Wifi fixer

I tried this but it burns battery like crazy, it also has a tendency to go into overdrive and start resetting the wifi every 2 seconds when it can't connect (if the signal is weak etc) which causes some major lag.

I'd rather just connect manually than suffer with that.
[Nexus One General] hbkmog:
Did you try the 7/22 build? That's the one people reported to have fixed the issue.

Although not very possible, but maybe the pulled the fix from the build?
[Nexus One General] y2whisper:
I am too having this problem even with the latest nightly and the weird thing is my device and my router have mac addresses starting with 00
[Nexus One General] pwig:
I just bit the bullet and unlocked and flashed my first ROM. Cyanogen RC2 seems to have fixed it. So far "crossing fingers."

Edit: never mind. All that for nothing. Ugh. This wifi problem is a goddamn ****ing joke.
[Nexus One General] hbkmog:
What's your MAC address for the phone?
[Nexus One General] mindfrost82:
There's basically two issues going on and it seems to affect different phones.

The issue on GitHub that is fixed by the new kernel/driver is different than the one the OP is talking about.

That issue seems to mostly affect MAC addresses that don't start with 00. The issue with that is that WiFi won't reconnect to an access point after waking the device up.

The issue the OP is talking about is more of a power saving issue. Regardless of the sleep policy, Wifi slows down or stops. It can slow down enough to make streaming music impossible.

The best way to test this is to turn off your cell connection (airplane mode, take out your SIM, etc), then use only WiFi. This way, you're 100% on WiFi without the possibility of it falling back to your cell data connection.

I have a 00 MAC on an At&t N1 and I have this issue.

As someone else said, mine seems to throttle the connection way down and it'll start messing up my streaming radio. I was mostly testing it with the SiriusXM app since I don't think it does as much buffering as Last.FM.

With no SIM in the phone and connected to a Linksys G router, my music would start getting choppy or completely cut out after about 10 minutes or so.

If I ping my phone's IP, it'll make the connection alive again and bring it back to normal speeds. If my XM stream stopped, I can usually ping the IP and it'll start back up again immediately.

If you setup a never-ending ping from your computer, then it should keep the WiFi on the phone from going into its deep power saving mode. I will test this theory today. The downside is that you may not always have a computer to be able to do this.

While the connection may slow down enough to effect streaming radio, it usually never affected my notifications and push mail since that requires small data packets.

So for those of you that say you don't have this issue, please try it in airplane mode or take out your SIM. Then listen to streaming radio (preferrably something that doesn't buffer much) for 10-20 minutes.

Last.FM buffers whole songs, so it might take longer to notice it in that app.
[Nexus One General] pwig:
00:23

So I guess there is truly no hope for me after all?
[Nexus One General] hbkmog:
Actually to be precise. The two problems are like this:

For phones with MAC address starting with non-zero. The issue is wifi policy doesn't work at all no matter how you set it. The wifi will idle/stop when the phone goes to sleep and may not be able to reconnect to wifi when you wake the phone up.

This above problem is most likely fixed by the new driver fix by Broadcom.

On the other hand, the other problem is like you said, power saving mode. And this problem affects almost every phone out there even with the MAC address starts with 00. But what's different here from the first issue is, here the wifi connection is weakened and degraded when the phone goes to sleep because the wifi chip is supposed to save power. That's why you get the choppy sound gradually and stream finally stops. But in the first case, the streaming would usually stop shortly afterwards and there's no response when you ping the phone. I've read that some people have this problem, they can receive email notifications and such during sleep but won't have VOIP ring.

That being said, the power saving mode issue is yet to be fixed. But I think it can be kind of solved through apps like Wifi Fixer because it will keep "waking up", "refreshing" the phone intermittently when the phone's asleep. I think that's the reason why some people reporting wifi fixer works for them, yet some others say no maybe because their MAC address starts with non-zero, which is actually the first problem, thus can't be solved with a work-around.

Also this second problem doesn't seem to affect people that badly because there are also people reporting being able to stream radio for over 30 minutes.

Can you try streaming with other online radio app? Because maybe other apps may keep refreshing data connection, so won't disconnect. Also another way to try this out is logging in an instant messenger app(nimbuzz, ebuddy, etc.), put the phone to sleep on wifi and then send messages to your phone, see if you can receive the messages or not. Email notification is another way to test it out too, although it could be slower and not as responsive.
[Nexus One General] myboo_1988:
this is my 2nd day ...i try to google the solution ?i guess is hardware problem?

my n1 cannot barely call...each time call the connection will end it after few second...or else it will be fine after 1 -2 hour...can make call and etc...after that the phone start back to normal the signal is full bar but just end it automatically
[Nexus One General] hbkmog:
Sorry pal, your problem doesn't seem to relate to the wifi issue this thread is discussing.
[Nexus One General] myboo_1988:
do u know where can i post?
[Nexus One General] hbkmog:
There's Q&A subforum you can post there.
[Nexus One General] myboo_1988:
the section is dead...no one bother me...sob sob...after root now what warranty also cannot claim arhhhhhhhhh:(
[Nexus One General] pwig:
I would like to clarify;

Yes I am in the boat where I have the 00 MAC address. So, if I ping my phone using "ping -t" it will reply endlessly. Albeit, the pings are between 120ms and 2500ms, and average around 220ms. Any other device on the WiFi network return pings of less than 1ms but whatever. Anyway, the constant activity keeps the phone connected. If I leave the phone alone for about 10 minutes or so WITH THE SCREEN ON OR OFF, the WiFi connection becomes unresponsive and I have to initiate a manual WiFi restart or I start up a program that uses the internet and it sort of kicks the phone into action, and therefore it reconnects on WiFi (usually with a new IP address, yay) or 3g.

In all fairness, the phone usually finds the WiFi as soon as the screen is turned back on, but why can't it just connect and STAY CONNECTED like every other friggin' device EVER?
[Nexus One General] mindfrost82:
Just to add to my post, the power saving issue does seem to have more of an effect on certain apps.

While listening to the SiriusXM app, it would just start to cut out and/or stop after 10-15 minutes.

I tried Last.FM and listened to it for well over an hour and the only delay was 1 or 2 times in between songs. I know Last.FM buffers entires songs at once while SiriusXM is more "live".

I would randomly ping the phone and sometimes I would get "Request Timed Out" and other times it would get a reply with 100ms+ times.

So even though the issue is still there, its less noticeable in some apps compared to others.
[Nexus One General] pwig:
The Sirius XM app has been totally useless for me ever since I updated to Froyo. I used to listen to it while riding my bike, but it just craps out on 3g, Edge, and WiFi. I am thinking it must be the app, not Android.

It's not an official app, after all, and it's not available from the market, and they are still are on version 1.0.0.

Unless I am completely mistaken?
[Nexus One General] jcar87:
[nevermind]
[Nexus One General] hbkmog:
That's the aforementioned power saving mode implemented in the wifi chip on N1.

They will have to disable this mode so that the phone can stay on wifi with full strength.
[Nexus One General] phiednate:
After months of irritation, wifi will finally stay active for me. I never really had the problem of wifi disconnecting when sleeping, just became unresponsive. Router would show it still connected but I couldn't ping it.

I decided to try a new ROM and see if I could fix my long standing issue. Using the following:

[ROM] TheOfficial Nexus1 - Manup456FroyoThemed - v2.10.2 - 7/23/2010

[Kernel] [.34.1, & .35] Hybrid AVS/SVS + 1113MHz Overclock (08/02/10)

Ping is much higher with the screen on vs off but my main concern was getting my mail notifications and ability to download which both seem to work fine. Right now, average ping with screen on was 154ms and 244 with it off.
[Nexus One General] tltester:
I'm reposting this here from its own thread, in hope to catch a little more attention:

Hi there.

I'd like to ask for some help from somebody who has already gone through all this.

My problem is the following: I'm trying to use SIP with WIFI on my N1 (froyo, enom's theofficial 2.11.3).

At the moment my screen turns off the connection greatly deteriorates (I still hear about 1/3 parts of some spoken words) than drops.

I've actually harvested a lot on this forum about WIFI issues. Found out about driver bug, asked Enom to include a fix from Broadcom in his wonderful rom and he did in 11.2.3. After installing it, my connection drop when listening to online radio and screen goes off were fixed immediately. Now I can listen for hours without problem.

However, the SIP problem is still there. I've tried to put sleep policy to always on, tried to use both C3X (with proximity sensor support) and SIPDROID, tried 2 different wifi fixers apps I've found (with all possible settings combination) - nothing helps. The fixer apps, btw, didn't have ANY influence whatever mode / fixes I enabled / disabled.

What's this? Is it another driver issue? Is there a rom that works as supposed to in same circumstances?

Thanks.
[Nexus One General] Jack_R1:
I would guess that it's wakelock issue - SIP probably requires way more CPU power than max-384MHz-clocked sleeping Snapdragon provides. Check that you're not using SetCPU to limit the CPU frequency with screen off, check with the application developer what are the required resources for the app to function correctly. Check the system log (kmesg) to see, what frequencies is the CPU scaled to when you're turning off the screen.
[Nexus One General] tltester:
Thanks.

Actually I didn't look in that direction - were just sure it's a wifi problem...

Is this 384MHz limit something that's hard coded and unchangeable? If I'll set the sleeping max. to, say, 600MHz with setCPU - may it help somehow?

BTW: Sorry for noob question - how do I access the kmesg log? I have kmsg on my n1 - one at /proc/kmsg and another at /dev/kmsg - both are shown as zero size.
[Nexus One General] mitcha:
N1 with Froyo 2.2 FRF91

Wifi Mac starting in 38:...

Just to say that WIFI FIXER solved my problem.

Ping my N1 to see how it works

As soon as the screen goes off, the are 3 lost of packages but after that everything working fine.

Pinging with no loss.

Wish that I didnt need to use a fix.
[Nexus One General] pwig:
I never got my phone to work correctly.

ATT phone with 00:23 MAC address.

I used a Netgear WNR3500 v1 for my wifi and no settings on it or the phone ever fixed the problem.

Anyway, I went out and bought the Cisco Linksys E3000 wireless router and IT WORKS!

I didn't like that I had to spend so much money on a wifi AP, but my problem is solved as far as I am concerned.

I guess an older router just doesn't have the ability to work with a low power mode from a Linux phone, or something.

I never had problems with any other router at anyone's house or at work, so I would bet that the Netgear router was the exception to the rule. Netgear never offered an updated firmware and it wasn't compatible with aftermarket, third party firmwares.

My plan was to go to Best Buy and continue to purchase and return routers until I got one that worked, but this was the first one I bought. I would suggest to other people that if you are desperate, then try what I did.
[Nexus One General] adamentity:
WiFi Pains...

I have seen a number of problems with the WiFi. First I narrowed problems down to my wireless router then beyond.

Initially, had issues with security of the router wheras open access was more stable when connecting\disconnecting. Still I notice that my high-end access point at work stays connected whereas my home access point gets disco'd and sometimes need a manual disable\reenable for the wifi to reconnect.

The WiFi sleep policy has never truly worked as expected when set to Never sleep, it will sleep regardless once the display has been off for awhile. However, if the screen is on and constanly streaming something it seems to stay up just find.

Lastly, I have noticed that when switching on wifi the phone finds it neccessary to transmit via 3G one last time before turning on.

I'de have to speculate but the problem lies within the limited power\capabilities\functions of the Broadcom radio and firmware\software controlling it. Not to knock Broadcom but that chip can only do one thing at a time successfully or should I same seamlessly. Reception degrades once you start over working the radio with lets say bluetooth and wifi and 3G running all at the same time.
[Nexus One General] Sleepingeye:
My experience seems to back you up here mostly, except I don't have a data plan so 3G has nothing to do with it. As a matter of fact, I have mobile data completely disabled and am on 2G to save power.

I believe I'm suffering from BOTH issues, as my mac address begins with 38. When I put the phone into standby, the WIFI connection drops regardless of what I do.

HOWEVER, if I use WIFI Fixer *AND* bluetooth is not associated to anything, it pauses for about 3-5 seconds (presumably after buffered data finishes), but resumes and plays largely uninterrupted from that point forward.

If, from the computer side, connect the A2DP service, the music stops. When I disconnect the service, the music starts again.

The above I tested with a really old BT1.1 class 1 (100ft) dongle that's falling apart. I then changed BT dongle (reports 2.0)... wifi and bt co-exist again for the most part (it does seem to drop out once in a while, but usually resumes fine after a few moments, not sure if it's a bandwidth issue or not).

It's probably not going to do anything, but I'm going to send it in for repair anyway as there are one or two other issues that haven't been resolve for my device (sometimes drag-dropping icons on homescreen doesn't work and -only after reset - shows up in some random folder.)

Edit:

Still tempermental even with 2.0 dongle, but still works sometimes
[Nexus One General] nachod0g:
I just tested the new FRF83 (2.2.1) and this is finally fixed! (At least somewhat). Pings now go through when the wifi sleep policy is set to never on phones with a mac address begining without 00, as they should.

I'm not really sure about this part, but looking at the new bcm4329.ko binary it appears this patch was included:

http://android.git.kernel.org/?p=ke...ff;h=8097ca0f92819b977472381f46315de15633361c

I can ping my phone and see it connected in my router admin pages .. but yet I cannot access internet or anything on my phone. Port is 80. See signature for specs .. any ideas? Very frustrating!

Also, when I change my wifi channel on router my, wifi on the phone works for one page load and then stops working.

Thanks

I'm using Wifi Fixer to resolve the Nexus One wifi sleep problem. It seems to work to fix this problem. But it's not starting at boot as it's supposed to. I have to launch in manually every time. Anyone got any ideas about what's going on? Thanks.

Same Issue

Hey guys, my friend has a nexus one and so I don't have instant access and she doesn't want me to install anything such as Cyanogenmod. Is there any way to quickly fix it without taking the phone for more than twenty minutes? Also, she doesn't have data.
[Desire Q&A, Help & Troubleshooting] slyb2:
I would like to get with a Sense UI ROM the ability to view in the HTC mail widget all the inboxes.

How it could be done?

Also does the Mail app from Froyo support multiple exchange accounts under a Sense UI rom?

Thanks for your input!
[Desire Q&A, Help & Troubleshooting] AndroHero:
no it cant be done, you have to switch mail accounts from you inbox, you cant view all mail accounts in one inbox, also yes it does support multiple exchange accounts :)
[Desire Q&A, Help & Troubleshooting] lywyn:
Looking for a bit of guidance on how I can switch ROMs without having to setup all my apps and settings again. Is there a way of app that can backup my apss or at least there settings/data so I don't have to start from blank every time I try a new ROM.

thanks Darren

there are loads of backup apps lol titanum in the market, also u can do a nandroid from recovery :)
[HD2 General] kertenkele:
Hi all,

Just noticed this issue and want to see if there are any others noticed the same before or can check their HD2 for same issue.

My HD2 screen is perfect under day light or yellow light at night. with no mark-spot and very smooth.

Bu last night I noticed that under white light like fluorescent, there is a mark at the center of the screen with colours. you can see it when the screen is on or off. But on daylight or yellow light lamp, you can not see it in anyway.

Can you please check yours in white light?

Thanks.
[HD2 General] kertenkele:
reminder please
[HD2 General] whatever999:
Could be a light case of newton ring...

I sat on my HD2 and ended up with what looked like a smudge / spot on my screen which had a kind of petrol rainbow around it...(you know when petrol mixes with water on the ground you can see a kind of rainbow effect??).

It was the "newton ring" issue, HTC replaced the screen for me via the service center...(search for "newton ring" on this forum and you can see many posts / pics I think)

What you have could be a light form of that, I guess the "smudge" (which was pretty prominent on my phone) is small on yours and you can only see the rainbow colours that appear around it...

On my phone the smudge and colors were right in the center of the screen...

Hope this helps.

Whatever
[HD2 General] kertenkele:
It is good to hear a reply. very clear.

Thank you.
[Android Software/Hacking General [Developers Only]] heroandroid:
Is there a way to change the kernel or script or whatever to get the phone to boot automatically as soon as a power source is connected?

I'm going to use a phone as a media device (will be in a closed box so nobody can fiddle with it with continues power connected), but it will be stupid for me to go to the site to turn it on if the main power has failed and the battery has run empty. I would like the phone to turn on automatically as soon as the main power is restored!

Any help will be appreciated!
[Android Software/Hacking General [Developers Only]] d1dd1:
bump !

Any solution for that ?

If I remember correctly, there were some Galaxy S ROMS where the device boots up when power is connected.

edit: It worked on some old CM7 ROMs
[XPERIA X10 General] boydivalor:
Hi,

Everytime my battery goes down 15%, my screen brightness goes to almost 0.

I cant see any setting to change this.

I dont have any app to do that.

Currently rba023 rooted.

Thank you
[XPERIA X10 General] Bigw@ve:
If there's a way to change it I would like to know as well. It's very hard to see for that last 15%.

Wish I could help.
[XPERIA X10 General] yetep:
The last 15% would last no time if it was at normal brightness. It's designed for, you know, if you need to use it in an emergency ;-)
[XPERIA X10 General] misterzak:
To get your brightness back go to the sound and display setting and click brightness. It returns it to full brightness. When your battery drops to 10% and 5% it will do the same.

As far as I'm aware there isn't a proper solution to this.
[XPERIA X10 General] Ungruntled:
My issue with the brightness is the "auto brightness" function seems backwards to me.

E.g. if I am in direct sunlight, auto brightness turns the brightness of the screen way down, which means I can hardly see it. If anything the brightness should be turned UP.

If I am in a dark room, auto brightness turns the brightness up, when really, turning it down would be better as it doesn't need to be as bright in a dark room. So it should be turned DOWN automatically.

It's arse-over-tit, as we say.
[XPERIA X10 General] boydivalor:
Yes,

But now with root, i'm sure anyone with the right knowledge can modify this 'stock setting' ! ...

Anyone to try it?

Cheers!
[XPERIA X10 General] im_iceman:
Hi mine seems fine.. Yours however does, as you say, seem arse over tit.
[XPERIA X10 General] suzed:
This doesn't really fix the query but for fast access to adjust the brightness I use an app called QuickSettings which I have on my front screen to give quick access to some basic settings. On the brightness adjuster you have to have the phone settings not on automatically adjust.

Hi,

I own new Desire phone and paired it with BT headset.

Once done when someone calls my mobile the phone vibrate but not rings and the sound is heard only in the BT earpiece.

Since i do not go aroung with my BT device attached to my ear i miss calls if i do not feel the vibration.

Can anyone faced such issue and have a solution?

Any ides?

Thanks

Tap and hold your bluetooth headset pairing - is it also paired as a bluetooth media device? If so, just un-tick that optiona nd you should et what you are wanting.
