[Q] Wifi continues scanning and browser speed. - Galaxy Note GT-N7000 Q&A, Help & Troubleshooting

Hey guys, I've noticed that under the wifi settings I can see it continuously scan for networks even though I've already connected to my router. Anybody else finding their note doing this?
Another question is with the browser. After you have multiple tabs opened up and you minimize the page so you can see all the other pages to swipe through. When I swipe between pages it's really choppy. In portrait mode it's a little better though.
Running non rooted, standard LB2 rom.

Mine has the same problem with wifi scanning but apparently no one has ever answered my questions about it, posted some months ago. My browser is floppy too.

I have read that the scanning only happens while you have it open. I do not know if this is true, and it is kind of a 'Schrödinger's cat', unfortunately.

It should stop scanning if you uncheck the second option from the top in Settings/Wireless and Networks/WiFi - Scan for New Networks.
Sorry if this is not precise, I'm on ICS rom ATM, so cannot check the exact path. But there is Scan for New Networks option, I remember that distinctly.

chasmodo - Don't think we have that option in gb.
After some more reading, as jeromepearce said it seems to only scan continuously while you are in that setting screen. Schrödinger's cat indeed =]
I need an app that shows current draw, missed that from froyo...

There is no option in GB to stop it scanning. There is an option to stop it popping up an annoying alert whenever a new network becomes available (immediately turned off in most cases, I would assume).
Using Set CPU just to open and see the CPU speed, it keeps jumping up from 100 MHz at about the same interval that the scan occurs while in the settings screen - ie every two or three seconds. If it really is doing this all the time, it would explain why WiFi uses so much battery. If there really is a setting in ICS (confirmation, please?) this maybe why ICS is so much better at conserving battery.

Using Push Internet

I just got my TD2 yesterday. Been trying to figure out the settings for the push internet, but i can't seem to find the option to use WiFi connection instead of data connection.
Also i realised that the scheduling doesnt allow to set the minute only the hour.
Does anyone have this problem?
No one has any problem using this feature?
If you have WiFi on it should just use it I guess? Otherwise what you can do is setup your preferred connection not to be the mobile web one so it doesn't try and connect to the net over GPRS/3G.
I tried using Wifi, but it doesnt work. I still need to manually pull the sites.
When your phone goes into standby the WIFI connection turns off to save the battery, so unless you have your phone set to never turn off and keep WIFI active all the time its unlikely that it will use WIFI to push internet pages to you. Very little point doing it that way since you'd never have the phone last long enough to get out of the house in the morning.
Oh I reckon I know what might be wrong. You also need to change the schedules of when the phone polls for sites. You do it by day and stuff and do a start time. Once you visit each site once then that'll start the ticker so to speak. Mine autodownloaded at the set intervals after that.
Thanks Shuflie, u have a good point.. there is no point updating it via wifi. It needs to use a data connection. Thanks
DaBountyHunter: Thanks for the advice.. but i really think the problem is that i dont have a data plan with my telco.. i cant rely on WIFI since it disables whenever the phone goes into standby.
hi,
i'm a little bit confused about this feature!
i addet 4 sites to my list and if i got it right, there is a grey arrow if its updating and a green if its finished! is that correct?
but, when i surf on a site with a green arrow i can only see the main page, because if i tip any link on this it says error!
thats a total mess, the deep of min one link is essential...
do i something wrong or is this feature only a dream!??
I believe it only updates the pages on the main page. It doesnt save the entire site (i wished it did) cos it seems rather redundant when it only saves the main page.
hopefully someone can make a fix that it also loads the linked pages but i think it takes up too much memory/battery life and for example on news sites you only need the headlines, and if you want to read the article you'll have to wait a bit.
(for the Dutch, use tweakers.net/nieuws on your phone, it loads the articles instead of headlines)
well then in my opinion this feature is senseless!
quite true.. senseless.. might as well just use RSS feeds.
I still haven't received my TD2 (seems like it takes time for other languages as I'm looking for a french one which should be shipped on the 8th of May) but I still have a question regarding push internet feature.
What happens when roaming? Is there a way to disable it while on another network? Like a "disable while roaming" feature? Knowing the fees for data roaming, I don't want to spend money every time I'm going in another country...
yes, there is a 'disable when roaming' feature.

i tried that, also tried many other things but i am almost defintely sure the 'add push page' is simply a bookmark button. the main conclusion for this is that i dont get any notification of the 'auto pull' and it still attempts to connect to HSDPA when opening one of these push pages
I stopped using it because it only updates the top page.
Where are the oush internet settings on rom official rom version 2.53?

Froyo + WiFi = disabled connections

So ever since I've gotten my Nexus One I've been noticing it drops out of a WiFi way too often. It does it both at home and at work on Wireless routers using the latest firmware. I've set the sleep policy to never go to sleep but most of the times I wake my phone up, I'll find it on 3G instead of the full strength WiFi it should be on. On 2.1 when I'd go into WiFi settings it would show the connection and say something along the lines of "Connection unsuccessful, tap to try again" and on 2.2 it just says "Disabled, Secured by blah blah blah". If I retry, it ALWAYS connects and WiFi will stay active for a short period of time before falling back to 3G.
Is there some way I can tell Android to retry the WiFi connection if it fails instead of just giving up? I've been looking through the WiFi API's on the Android Developer site and I'm this close to writing an application that will attempt to mitigate this issue for me.
If I'm within range of one of my pre configured networks, I want the phone to try it's hardest to stay on WiFi. If it loses connection, retry. It it can't get it after 5 retries, wait five minutes and try it again, don't just give up and mark the connection as disabled.
I've read tons of threads about people with WiFi issues and people always say "it's the router, it's the channel, etc, etc" but my WiFi works perfectly fine as long as there is a human to reconnect it if it drops.
Anyone else in the same boat as me?
ok so apparently I'm the only one with an N1 and a WiFi issue.......
I have the same exact issues.
I have the same issue as well and if it stays on I have to turn wifi off and back on so it will connect properly

same issue here. i had been looking for an app that would force the connectivity, but the market doesn't seem to have it. just a bunch of crappy wifi on/off switcher management apps. i'm surprised that no one has hacked this function or built an app for it.
It's certainly a very annoying problem. Mine will go to known good wifi networks, at work, at home and at other locations where my other devices work flawlessly. I have a coworker with the exact same firmware (we updated using the same file) on a nexus one that has never seen this problem, which I find odd, but I'm fairly new to Android. It looks like a software or driver issue to me, but as I said, I'm new to Android.
My device shows the known networks as "Disabled", but I can connect manually.
Looks like it's worth me coding up an App to fix this then.
what kernel are you using? i used to have that problem but that has gone away with newer kernels. unfortunately a new problem has arisen where after being in standby for a while, wifi shows as connected but doesn't have an outside ip. wondering if its my rogers modem or not.

Personally I wouldn't do any work towards writing an app to fix this since it looks to me to be an OS or driver issue that should be resolved in a future release (hopefully in very short order).
An app would really just be a band-aid, but I'm the lazy type and I can deal with using my cell ular data when I don't feel like reconnecting my wifi.
Full disclosure: I'm a crummy programmer and it takes me forever to write stuff so I'm usually less inclined to do it.

I'd rather take the time to fix it then wait for an update that may never arrive. Always fun digging into the API anyways
That's cool. I still find it a bit troubling, though, that some devices see it and some don't, using the same firmware, on the same wireless networks.
I guess it could be a board rev. difference or an app conflict or something. ::shrugs::
I have a similar problem. I use APNdroid to keep cellular data off and use wifi, but I continually have to reconnect wifi no matter what if I am not actively using it. Defeats the purpose of push email.
I downloaded APNdroid after checking data usage and finding that with wifi on there was still significant 3G leakage. Especially confusing with wifi set to never sleep and plugged in overnight.
On the plus side, APNdroid has netted me a lot more battery life, I can almost get two days and one night. I almost never use my spare battery anymore.
Just as an additional data point, I am having the exact same issue with 2.2 FRF83 (I had been on FRF50).
It looks to me like it is simply scanning all of the time and never associating with a known network. I'm not sure why it flags them as "Disabled", however.
Have you guys tried to set the "wi-fi sleep policy" to "never"
if not, try this:
Wifi settings->menu->advanced->wifi sleep policy->Never

Yeah, it doesn't help, that was one of the first things I tried. Any time I leave and come back, the networks show as "Disabled". It's a frustrating issue in that it isn't consistant. It's 80% fail, 20% work.
I had my g1 for a year now and just now got my n1. I havent rooted it b/c of this bug. At first i couldnt listen online radio b/c as soon the display went out it would buffer the whole time. I played with the wifi router and the n1 wifi settings an managed to fix it somehow, BUT when i wake up in the morning for some od reason it lost connection and never reconnected again. So i can hear online radio with the display out but after some hours w/o online radio and just in standby it loses wifi connection and never connects again
This issue is not new. There is a thread on the google forum many pages long. Nobody hase even a clue where it could come from. Some1 on the forum said if u call support they will tell its ur routers fault.
The n1 completly ignores the sleep policy settings.
I have rooted two g1s with goldcard and still using one w/o a problem.

Well, I know fore a fact it's not my access point. I am a network engineer and worked on wireless systems for years and debugging these types of problems is something I'm a bit obsessive about. This stinks of a software or driver problem to me. It could potentially be a hardware revision issue since we have a N1 that works perfectly in all scanerios.
I've tested this with the following access points:
Apple Airport Extreme
Apple Airport Express
Meru
Cisco 1231
Cisco 350
Belkin pre-n
Linksys WRT54G stock
Linksys WRT54G dd-wrt (I forget the build number)
Soekris Engineering running pfSense
All exhibit the same behavior, while my control devices (Apple iPhone 3g, Apple Macbook Pro and a MyTouch 3g running Cyanogen 2.1).
I wasn't aware that this was related to rooting, I'd be more than happy to move back to a stock ROM if that solved my problem. Maybe I'll try that today if I get some time.
Could you possibly post a link to the google forum you're referencing?
I'm currently digging through the alogcat output to see if there is anything interesting in there.
This issue is worse since I upgraded to 83. I'm actually holding off to try CM6 when it comes out to see if there is any better performance there. I'm not sure if he uses updated drivers or kernel that may give better wifi performance.

[Q] new to the forum new to droid, new captivate

Hi everybody, new to the forums and new to droid - I recently upgraded from the Propel to the Captivate and so far I am loving it. With all the reviews and forums I read before deciding to buy most of my answers have been answered, but not all.
My phone was loaded with 2.2 and when I registered it with Samsung it showed a build date of feb/11 so I'm hoping that my phone has alot of the big fixes already loaded. I have noticed that the gps code listed on this thread
http://forum.xda-developers.com/showthread.php?t=732030
Does not work on my phone, I enter *#*#1472365#*# and the last * just clears the code out of my dialer... no sub-menu, no options, nothing. Any ideas how to do gps testing?
Other question, I spend alot of time off the cell network and I need a gps that works - which app would be good to use? Searching the app store there is quite a few ranging in price, most seem to have mixed reviews. Google does nothing for me since it needs the network to pull up the maps. Basically when I load up the gps it shows me in a sea of nothingness and trying to scroll the map gives me an error 'need network connection' type of message.
Also, I've noticed what looks like 2 small led's one the face of my phone, just to the left of the speaker and the ugly logo. Are these notification leds or something else?
I don't plan on rooting or flashing my phone for a while... yes yes I know, stock sucks, but like I said I was using the Samsung Propel a couple days ago and now the Captivate - I've got alot to learn and alot to get used to before I switch things around. Yes, one day I do want to switch off of stock software just not right now, thanks for the suggestion though. lol

As for needing a GPS on without using Data there are a few but to be honest if you need it for reliable GPS, then you got the wrong device. The captivate is known for having terrible GPS and it is unrelible at best. Good enough to help you learn a new town but not good enough to get you where you need to go on time everytime. The led are the light sensors. No led Notifications with the captivte at all unless you rom a custom rom and get BLN from the app store that will light up your 4 bottom keys when you have a message.
I do have a stand alone gps, I was just hoping I'd be able to free up some pocket space with the phone - so far, it just shows a blank screen with a blue indicator and says it's accurate 'within 10 meters'. I was hoping I could find a app that provided maps and maybe help tune it a bit. Next time I'm on the network I'll play around with it and see what kind of readings it gives - even if the gps is low end, I'm still liking this phone so far... a whole lot better than the propel.
Thanks for the update, zelendel

One is a proximity sensor and one is a light sensor.
Thanks for the info, I got a couple gps test apps I'm going to mess around with in a while but, I found a new problem that is driving me crazy...
I bought a usb wifi adapter - Asus n13 (b/g/n), in the hopes of using my internet for data and my phone will not connect to wifi. Even driving around town to places that offer free open wifi, my phone will not connect. It finds the wifi hotspots, pulls up the ssid, says connecting, then gets to 'assigning ip' and freezes. On my pc wifi setup, it shows a new connection and 2 seconds later disconnect.
In the phone wifi settings, it keeps showing wifi -connecting....disconnected, back to scanning, connecting in an endless loop - but it never connects. It has the ssid remembered but I cannot delete it or reset it. WPS failed to connect from either end.
Sleep Policy is off
Use Static IP is off
This is a big issue for me since I'm on the cheap att data plan.. I've tried various settings on the pc side of things, all with the same results, I've browsed the internet and done a bit of troubleshooting (ie, different usb ports, different drivers, turning on/off services, etc etc) - I think the problem is on the phone since it does not access any wifi... maybe I missed a setting somewhere?
For now I'm going to dig through the user manual again...
OK, playing around with some of windows wireless settings I've hit a new roadblock... my phone says connecting... Obtaining IP address... Disconnecting... Scanning...
That is one small step closer I think, because it wasnt trying to get an ip address earlier, it was just connecting/disconnecting.
finally! I figured it out!!!
Just for future note.... You have to go into your windows network settings, highlight your broadband AND wifi together - select bridge... restart your pc wifi software and then connect your phone, it should start right up!

You say you do not want to root the phone. But try Launcher Pro anyways to access the LbsTestMode.
1. Sign up/in to the market.
2. Download and install Launcher Pro (it says Pro but there is a FREE version, so dont worry).
3. After install, go to home screen. Long press and choose "Shortcuts"
4. In menu, choose "Activities" (yellow icon).
5. Scroll down and expand the menu "LbsTestMode". Under this is a submenu. Choose the first "LbsTestMode" under this. Yes the main menu and submenu have same name.
6. Choose Ok or whatever, and the icon will be on your Home screen.
7. If you get this far, then you are good.
Open LbstestMode:
1. At the moment you probably should just leave Application Settings to default.
2. Under "Supl/CP settings". And change as follows:
Server: supl.google.com (no "www.")
Server Port: 7276
Secure Socket: OFF
AGPS Mode : SUPL
3. Return to previous menu.
4. DELETE GPS DATA just to clear all previous data.
5. Run "Get Position Test" on top of menu.....
Good Luck !!

Yeah, Google Maps requires a network connection.....BUT when you go into Navigation mode - via the Directions menu and turning on navigation, you get navigation. YOU NEED TO DOWNLOAD VOICE SYNTHESIS from the market to get voice guidance. This a good first try, IF YOUR GPS WORKS !!
Or try NAVIGON for Android ....you can buy it but also check here www.mobilism.org (ahem..ahem). I use daily, and I think it is the best routing....
EDIT: Well...about google maps, I think you need a data connection jsut to open the damn software, so you will need Navigon, Igo primo or similar...I AM ASSUMING YOU WANT ROUTING DIRECTIONS and not hiking type positioning. Then take a look at this http://www.backcountrynavigator.com/content/android-gps-software AND here http://www.backcountrynavigator.com/
Thanks again for the updates, but it seems like either Samsung or ATT has locked out the Lbs Test mode feature, both of the codes have the same result - after entering the last character it clears it out. I did get LauncherPro and am really digging it so far, but even the lbs tests dont do anything, it goes to a blank screen and just sits there... I have the status bar at the top and a totally blank screen. I even set my phone down on a box out in the yard for 30+ minutes and nothing ever came up - using the google and stock settings for the test. I'm guessing if/when I root my phone the tests will work
I started using GPS Test from Chartcross Limited and GPS Status from EclipSim - both show that my gps is accurate between 16.4 and 32.8 feet - depending on which the way the wind is blowing. I've been browsing some of the other gps/map apps but for now I'll just carry around my standard gps when I need it.
Even with the gps issues, I'm really liking this phone alot. I havent really ran into any other problems yet

wifi goes to sleep?

I am on GDX version 19 (i know it's a bit outdated but hey most things work so no incentive to upgrade). I notice that from time to time if I let my gadget suspend my wifi might get disconnected. I have doublechecked the wifi setting and sleep policy is selected as "never". So I assume that means wifi will never go to sleep. Well, then why does it get disconnected from time to time?
Is this a featured bug?
Sometimes it happens to me i guess it might be that if there isnt an app using wifi it disconnects
Coz it never disconnect when am downloading and the phone is asleep
Sent from my E15i using xda premium
Run GDX v25 instead it will probably fix the problem

go to Settings -> Wireless & Networks -> WiFi Settings -> Menu Button -> WiFI Sleep Policy -> NEVER
DONE! hope it helps...
#4 plz read my original posting in completion first
#2 I am wondering myself as well - if there's no apps using wifi and my sleep policy set to never whether it is supposedly to stay on without cutoff. Never sure about this. I have searched in the forum a bit but I have never got a definitive hint on this. I do experience occasional cutoff while using the internet but it's a rare occurrence that it does not warrant my attention yet.

WiFi gone..

Hey there. Had a strange problem, happened 2 times till now. WiFi was completely gone, went to the settings/wifi and wifi was still on, but the list of AP's/Networks was completely empty. Anyone had that happen ?
greets,
nEUTRon
No one, really ?
I've had the saved Wi-Fi connections be forgotten after a reboot/shutdown. Happened this morning actually.
I have tons of wifi problems, but not this one. My wifi takes a long time to come on after being turned off, often more than a minute, and the wifi setting pages hangs.

This can happen if you have multiple devices. The wifi password file acquires multiple entries and the phone fails to pick one. Longstanding bug Google is ignoring. If you have a rooted device you can read the wifi supplicant file and see the multiple entries to confirm this is what's happening to you.
This is happening to me more and more on my Nexus 6. I'm rooted and stock. Haven't found a solution yet.
My WiFi situation is a disaster with nexus 6 too. No problems at al
l with nexus 5 and nexus 7 (2012)
