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

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] Anyone else having wifi issues since OTA upgrade?

My unrooted Xoom does not want to keep connected to my wifi signal since the upgrade. I did not have this problem before, but now if I set the Xoom down for a minute or so, the screen on or not, and pick it back up it is no longer connected. Sometimes I find I am without a signal when clicking on a link just after entering a web site while actively surfing. I have the wifi disconnect policy set "Never." Is anyone else experiencing more problems since the upgrade?
No issues for me so far.

The only wifi problem I have is the kernel wifi driver memory leak mentioned elsewhere. My xoom will eventually reboot itself if left on wifi overnight.

This really sounds like the WiFi driver leak problem as mentioned before. Your symptoms are exactly what I was experiencing, pre upgrade.
The workaround is to not set the disconnect policy to "Never". Since I have turned that off, I have not seen the problem.
Nope... no problem here... tried to restart?

Sorry, no problems here with wifi.

No problems here either.
Thanks everyone for all the input.
I must have missed the discussion on the wifi driver leak problem but will do a search on it. If you don't use the "never" setting, which one do you use? It looks like a compromise with the other two settings as I like to have the email and the internet ready and waiting when I turn the Xoom on.
To another suggestion, I have tried rebooting several times.
After further use, it now appears to be an intermittent problem as on occasion today it has not been dropping out.
Im also having this problem since the OTA with my Wireless tether connection.
The tiamat kernel fixes the wifi issues. Check it out in the dev section
i am running stock xoom non rooted. I too am seing issues occasionally with wifi. I have noticed the signal has become lower since the upgrade. My connection used to he good and now ranks as fair. I have restarted bit he the access point and the xoom no change

WiFi randomly fails to connect after last update

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?

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.

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.

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.

WiFi disconnects often?

I'm really happy with the phone so far, but my wifi disconnects fairly regularly and I keep getting a force close on the SMCC Process (whatever that is). Anyone else having problems?
I just read the thread below this and that issue seems similar.
EDIT: I tried turning off the smart wifi, but it still loses connection. The phone still shows that it's connected to whatever wifi signal, but stops downloading. This happens both at home and at work, so I don't believe it's related to the router itself.
I'm seeing the same issue on mine as well. Noticed it last night playing Pandora via wifi. Would play like 3 songs then nothing. I would have to toggle wifi on/off to get Pandora playing again.

Sounds like basically the same thing. If I wait long enough, it comes back on its own, but it's faster to just cycle wifi or airplane mode once. It's fairly frustrating, and I even found myself just using 3G to do things last night instead of Wifi.
seems to be a known issue in other S4 forums:

Mixed Mode WIFI
I had this exact same problem with my EVO 4G LTE, the problem was the mixed mode WIFI. (B,G,N). On the EVO it turned out to be an easy fix because there was a setting in the WIFI menu to force either B or G. As soon as I selected one mode I had a solid internet connection. The problem here is there does not seem to be an option in the S4 settings to allow this. I have been trying to force single mode on my router to see if that will fix it but my router will not allow me to turn it off either. Pretty serious bug I would say.
WIFI worthless on brand new S4

it doesn't do it as often as it did with the SGS3 though
I really wish I could find a resolution to this. I'm thinking of wiping my phone and starting over to make sure it isn't an app issue, but man that's a lot of work.
Im having the same issue as well.. Im almost positive its common issue and i would expect it to be addressed in the next OTA
The common link seems to be DLink router. We have a Cisco Linksys router and it stays hooked up solid on that.
I have an Asus router. Don't know if there are usually problems with those or not, but I haven't had any prior issues.
I have a Cisco e4200 stock and a Asus running ddwrt operating as a wireless bridge to extend my network. I had to turn off mixed mode on both devices to resolve the issue. Hope that helps.

I have the same problem but I have Netgear routers. The one at my house works fine, but at my other location. The wifi drops.
Same problem on dlink
Adding my 2 cents because I have 2 S4's that I've been testing with and I'm getting mixed results... my first post here so I hope I'm doing this right!
I have 2 wireless routers at home:
- DLink DIR-655
- One provided by my ISP (Bell Canada; not sure of the model at the moment)
The DIR-655 is troublesome for BOTH S4 devices; they stay connected for a few minutes (or longer in some cases) but will always end up not transferring data even though they show as having a very strong signal. Turning wifi on/off always fixes the issue for a short period of time.
Knowing that there seem to be compatibility issues with the S4 and DLink router, I switched them both over to the Bell router. Now only one of the devices has the wifi issue described above.
I found it odd that changing the router being used fixed the issue for one of the devices but not the other. I'm now questioning whether one device has a hardware issue or not (doubtful on this, but worth questioning).
Both S4's have the most up-to-date firmware as do all of the routers in the house. No other devices (iPhones, laptops, apple tv, etc...) have any issues with the wifi.
I've tried resetting the routers, forgetting the wifi connection and setting it back up, rebooting the phone, smashing my head against the wall; nothing seems to have worked permanently.
Is it possible that this is a hardware issue and not a software issue? Has anyone else had similar results with multiple devices?
fix....?
this wifi drops are due to the router WIFI signal setting. it will drop it you are using a B/G Mixed signal/ B/G/N Mixed signal. i recommend setting it on 802.11 g. or, if all your Devices in the house have N use N since it has more bandwidth. i use G because of the PS3
Hope this helps resolve the issue for you guys, it sure did for me.

Thanks for the suggestion, I can attest that this wasn't a permanent solution for me. After switching to N mode only, the amount of times the issue occurred was reduced, but still happens at least once per day.
It's also a pain when I'm connected to networks where I have no control over the wireless settings (work, public networks, friends networks).
I have a linksys modem and router. Haven't had a single connection issue with this phone as I had with my EVO. As my wifi disconnects and reconnects right away. Lol. First time that has happened. Knocked on wood.

Intermittent Wifi Disconnect - Logs included

My Nexus 6P has the bootloader unlocked but is running completely stock, un-rooted, vanilla android (MDB08M). Project Fi is my carrier. When I am at home and on *most* wireless networks, I see no issue. While I am at work, my wifi constantly disconnects and reconnects. I will pick up my phone, and it will either A) not have wifi (though I have previously been connected) and quickly reconnects or B) Will have wifi, but after some amount of use, will disconnect from wifi, then reconnect a few seconds later.
I've tried all the simple items:
Making sure "Keep wifi on during sleep" or whatever the setting is is turned on
Turn off optimization on Google Connectivity Services
Forget network and reconnect
etc...
I turned on verbose wifi logs and was able to catch a logcat of when the issue occured. The disconnect occured at almost exactly 9:29:00, as I saw my wifi go out and then almost immediately after the clock tick 9:29.
I can't find anything in particular that stands out as the cause or leads to a solution.
I assume it is some misunderstanding between my job's wireless network and my phone. My previous phone (Nexus 4) had none of these issues. I am unclear on whether this is a Marshmallow issue, Project Fi issue, or what software might be causing it. Since it only happens on this certain network, I am making the assumption it is most likely software and not a faulty wireless chip. I have no control over the wireless configuration of the network, so anything on that end is a non-starter.
Any help or direction on where to look next is greatly appreciated!

I have exactly the same issue. It seems to happen mostly at work - my phone is locked laying on my desk for some time, and when I pick it up and unlock it, there is no WiFi connection but it reconnects after few seconds. It happens randomly as sometimes WiFi connection is there after unlock. It also happend at my home wifi network, though it's more rare at home.
I have two friends at work having Nexus 6P and they don't have this issue, so it looks like something wrong with my unit. I have 'Keep wifi on during sleep' turned on. Any ideas?

If those are your bug reports, the error in the reports:
FAILURE: LOST_PROVISIONING, NeighborEvent{elapsedMs=94908702, 192.168.1.1, [(null)], RTM_NEWNEIGH, NUD_FAILED}
is the same error I'm getting. My phone disconnects while the screen is off, I've just also caught it disconnecting with the screen on too, so I'm under the impression our situations are related, if not the same.
Thank you for the bug reports!

Not getting this error in my reports, but experiencing the same issue on stock 6.0.1 rooted. Can't find any solution.

I wasn't getting that error either, one of the Google engineers on cpswaim's bug asked me to open a new bug report instead and I did so here: https://code.google.com/p/android/issues/detail?id=197272

Thanks for the link!
Since Greenify's Aggressive Doze feature is what caused my status bar clock to freeze last time I had an issue, I disabled Greenify but my wifi issue persists (although not as severe). I got a logcat and saved it right after the wifi dropped and reconnected, anybody with some knowledge who can see what's going on in there?
Edit: The general consensus online is that this is a Marshmallow issue. I don't have unlimited data so at home on wifi, this is a killer.
So I reflashed my stock boot image (6.0.1_r3 MMB29M), flashed FED Patcher, flashed the latest systemless root (2.64), and deleted the legacy directory Chainfire had made for old root apps that hardcoded to su (I deleted /su/xbin_bind) to get Android Pay working again...
My wifi issues have disappeared. I've seen a lot of reports saying the issue mysteriously resolved itself, but could it have been anything I just did?
Edit: Wifi is still randomly shutting off while the screen is off, but will even sometimes turn back on. The intermittent connection dropping is gone though.
This has been a constant issue for me starting with the Developer Previews on my Nexus 5 and has now moved onto my Nexus 6P.
i'm getting sick and tired of these little issues. google needs to fix this **** asap. such bull**** to have to deal with this crap
I had this issue on my home network with my Samsung devices. My tablets and TV would always drop off. My router was a cheap Asus model and was showing its age. I bought the brand new Asus router
"Asus - Extreme Wireless-AC2400 Dual-Band Gigabit Router - Black
Model:*RT-AC87R/U"
And I have not had a single drop since. Even on marshmallow. Now I know this isn't a cheap or reasonable fix but it seems maybe older hardware is to blame. YMMV

Unfortunately this is the same router with which I am having problems as indicated in my bug report. I've also found at least a few other anecdotal accounts of problems with other Quantenna-based routers as well. The evidence seems to be fairly sparse though, so it's hard for me to draw a meaningful conclusion from what I've seen so far.
For whatever it is worth, I currently have another user with a Nexus 6P on 6.0.1 on my network on that device doesn't seem to have the same issues that I am seeing.

Well that's lame. I have had no problems since I got mine. I did get my own cable modem at the same time but don't see any connection there.
I'm guessing we're waiting on an update from Google?
My random disconnects have stopped, but wifi will still randomly shut off/turn back on in my pocket. Even in Safe Mode.
Flashing factory images and factory wiping haven't solved the problem.
Is anyone looking into this?
Edit: Even after the January security patch update, still having these issues.
It seems like my wifi issues have resolved themselves somehow.
FWIW, I was having a similar problem on my Sprint HTC One M8 after upgrading to Marshmallow. The problem happened on every wifi I would connect to... work, home, a friend's place, etc. After trying out several things, I finally fixed it by uninstalling "Sprint Connections Optimizer". I tried disabling it first, but every time I disabled it and went back into the settings, it appeared to still be enabled. So I'm not sure if disabling it was actually working.
To uninstall it, you need to go into "Manage apps" from your apps drawer to find it. I don't think it's listed with an icon in your usual set of stock and installed apps.
Posting this just in case no one has thought of it before, or someone knows something and hasn't spoken up. I have noticed a lot of people mentioning they only have this issue at work, and others who have "changed their router" and stopped the behavior.
I run a Cisco Wireless LAN Controller at home, with multiple APs (Cisco 1252 a/g/n). Typically this gives me better performance and stability than most consumer-grade stuff, but I have to wonder if there isn't a setting on this enterprise-grade stuff that is related to the disconnect issue, or if this is truly simply a Marshmallow bug. This could also be the common link with people who only have this issue at work, their work may be using Cisco enterprise Wireless gear.
I will do some more digging, I did have a spot in my house where my phone would randomly disconnect, turning on "Fast SSID Change" stopped that, so I am hoping there is something that might affect this disconnect while sleeping thing as well. I noticed my WLC reports my phone as being "Power Save Mode ON" in the client info page.
More to come if I discover something.
I have same issue at home, stock Nexus 6p and an AT&T router. Limited Data plan, so it's frustrating to be at home sitting 2' from WiFi router & drop off.
If people might say how they get their log errors & post them to Google, that'd be interesting reading.
I'm 90% sure this is a software bug. My wifi is consistent & always on, iPhones & Note 3, Roku, & PS3 have no problems connecting.
Please Google find this bug & patch it!!! (And while you're at it, re-enable Dark Theme setting!!)

Add me to the list of people having this problem. I am between several different locations on a typical week and so far, the Cisco AP's by far have the most issues. In fact at my locations with Ubiquiti AP's, I have a perfect connection with no drops.
I really hope this gets resolved soon as well. Many applications are unusable when the WiFi does its drop and reconnect dance.

[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.

Are you still having issues or did you find a fix? I am having the exact same problem with the exact same router.

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.
