Wif disconnecting and reconnecting while downloading or surfing web - Asus Transformer TF700

Has anyone noticed their wifi disconnecting since the latest update?

My WiFi doesn't connect after coming out of sleep sometimes. When I go to settings to check on the WiFi status, it is turned off. I've also noticed that although I have changed the option 'Keep WiFi on during sleep' to only when plugged in, it reverts back to always...even though it reverts back to always, it still does not turn on WiFi when coming out of asleep. My Acer a700 does not do this.
This has happened since latest update (26). I don't remember it happening prior to update.

I have been testing this more and more and it is happening when ever I am downloading a lot of data. I have tried multiple network settings and different networks and the same thing keeps happening. My WiFi will disconnect and then reconnect. Latest test was trying to download music from my google account to the Infinity. It starts downloading and then in a few minutes I get no internet connection. then it is like wifi turns back on and reconnects. Is anyone else having this issue. Can some others test this. I have reset the tablet to factory defaults 2X and I still have the issue.
Thanks

I have noticed this issues multiple times now on multiple different networks. There is definitely some sort of issue with the wifi...

I have had a TF101, a TF201 and now a TF700. Docked or undocked I've never had disconnects in WiFi. This is in spite of the fact that there are maybe 20 other WiFi networks visible. I guess I have a good WiFi router and do use a WiFi extender downstairs.
Bye.

Had this problem with my TF201
Set my router up to only use one channel and it helped. Used WiFi analyzer from the market to determine which channel was best.

Keep in mind that it could disconnect and reconnect without you even realizing it. I just happened to notice the wifi symbol going away and coming back on it's own a few times (one time, while waiting for a web page to reload). So, it *could* be occurring and you not even realize it...
Not a huge problem, but a problem nonetheless...

I've noticed this problem too, only after the .26 update :crying:
(coïncidence ? I'm not that much of a downloader to be considered as reliable statistics )

The only time i saw it constantly connect/disconnect is when I did a hotspot off my phone and didn't enter the password in correctly. It didnt tell me it was wrong, just kept trying to connect over and over untill I stopped it and did a "forget" then reconnected entering the correct PW this time.

I did not notice it before the update either. I did not notice any issues when downloading all my apps the day after I received the inifinity, but since the update I have had the issue trying to watch TV on the Infinity and now when trying to download my Music from google. I also notice it running speedtest app.

This issue is not "constant" - like I said, most people wouldn't even notice it, unelss they were actively transferring something when it happened... It's *very* intermittent.

How about this . . . . I have never had an issue, slow-down, ANR, crash or other user experience malfunction that I would relate to WiFi connection or disconnection.
My WiFi is rock solid! :good:
Bye.

Another one bites the dust. Check this: thread: http://forum.xda-developers.com/showthread.php?p=29648346
Basically since ICS google has screwed many customers. Like i have a Zyxel P-2812HNU-F3 and when i use the default 802.11g/b/n in router settings, then my galaxy nexus and infinity wifi will behave like yours. When downloading something or sometimes in browser, wifi disconnects and reconnects. Whats your router name? And also if you havent already, try going into router settings, change "Mode Select" to 802.11g Only. See if that helps. Still google screwed up when wifi works perfectly on my SGS2 on 2.3(using a custom rom on 4.0.4 which works great with wifi :S ) but not on nexus and infinity on 4.0+

[Q] Issues over latest update

i apologize if this has been addressed before, but i was unable to find any threads about this.
I've had my tf since day one and have not had any issues until now. ever since updating my tf, it will now power itself off while in standby mode. This has happened three times so far.
2nd, the wifi connection is now dropping while in standby and it will not reconnect unless i power down and back on.
has anyone else ran into any issues with this new update?
No issues with most recent update here, it fixed all minor issues I was having though.
No Issues So Far
No issue so far for me either. Things seem to be much stable and fast. Will continue to monitor it through.
Sleep of Death still a problem.

This has happened to me occasionally with the new update. I have 2 separate things that happen.
1. Wifi will be connected but I can't get out to the internet (its not the wifi router)
2. Wifi drops and when I go into settings wifi is turning off, but never actually turns off and is just grayed out. When this happens I have to reboot.
Since installing the OTA update this morning (I'm in the UK) my tablets been going into 'deep sleeps' a hell of a lot more often. I've had about 5 already today when it previously only happened once every few days.
Very frustrating.
Have a 16gb and no problems for me.
Updated to the latest firmware and still turning off when put on standby

Wifi errors

OK so on my open network at home o can connect but then I lose internet connectivity after about 5 minutes. Recently today though when I go to shut off wifi and bring it back on, it just reads error and won't let me check it back on or off. I then power cycle the phone and I'm back to square one with the 5 minute disconnect. Wtf

I replaced my router today and my wifi issues went away. I'm sad to find out the Atrix 2 doesn't support 5ghz wireless N
This is a motorola bug. It exists on the Atrix 2, Droid 1, Droid X, and Droid X 2.
It has something to do with the method the wireless radio in the phones notifies the AP that it is going into low power standby. So far I've been unable to determine the EXACT reason that it does this, but have a feeling its related to using WPA/WPA2 and sending the LPN to the AP with that enabled.
I'm trying to figure it out, and if any one else experiencing problems with wifi where it drops connectivity after 2-5 minutes, please let me know the following info:
Length of SSID
Brand of Router / model.
Encryption type: EG, WPA2/CCMP (CCMP=AES on some devices)
length of encryption key.
I'm going to try and find a way to fix this at the router, provided the settings are available.
Ssid is the same as router name WRT330N. No encryption. Got my new skyrocket no more wifi issues

I am experiencing exactly what you described, every time I connect to WPA2 network at my college I experience weird problems. For example when I stream music with GoogleMusic I can barely go through one song. On the other hand I have no problems at my home where I also use WPA2. The most confusing thing is that my phone acts weird on unsecured networks too.
Do you think this is a software issue ?
For those who are seeing the poor WiFi connections that lock up after a few minutes...
Go into your router settings and disable WMM.
I am told (by a reliable source) that the problem resides in some T.I. drivers commonly used in Moto phones and it's exacerbated by overly strict code in many routers.
In any event, I was suffering terribly unstable WiFi connections that would lock up every few minutes. As soon as I disabled WMM on the router, everything started working cleanly and has remained that way.

I will most def try this out (though i'm limited to devices I have management access to), hoping for the best (my wifi works well, but does seem to drop off sometimes and other times no problems whatsoever...)

Wifi Dropouts

I rooted my TF300 the other day and everything seemed to be working fine for about 24 hours and then all of a sudden I've started experiencing wifi dropouts. The really annoying thing is that it shows that I'm still connected to my wifi router, but I'm not getting any data. I have to disable wifi on my TF300 and then enable it again and it works, so I know it's not my router since all of y other device still work with out having this problem.
How do I fix this? Is there a setting in the build.prop that I could tweak to make this work again?
Sent from my ASUS Transformer Pad TF300T using Tapatalk 2
Hmm, now my TF300 can't connect to the internet at all. It still shows as being connected to wifi and I'm even getting a blue wifi indicator showing that it's connected to gogle servers, but for some reason I can't actually send or receive any data. Does anyone know what I can do to fix this?
Have you tried a cold boot? If that doesn't work, you could try a factory reset.
So I uninstalled adfree and lookout and now ,y wifi works fine again. I guess one of those apps was causing the problem. Weird.

WiFi Randomly Loses Ability to Connect?

Since the OTA update before last my WiFi has been weird, whenever I turn it on and connect to a network, after a random period anywhere between 1 sec and over an hour it will disconnect and completely refuse to reconnect, saying failed to connect. The only way to reconnect is to cycle the WiFi power completely. I was hoping that the last update would correct the problem, but no luck. My system is currently fully stock, no unlocking or subversion so far.
Any ideas or fixes?
Attached is the relevant system information.
UPDATE : I'd like to refine the problem a little; when the problem manifests, the tablet completely fails to recognize that there are any networks in range at all. Once again, it's solved by only a quick cycle though.

I've had this same problem a few times too. Cold-booting three times in a row then running an FMR memory clean usually works to fix it for me. But I'm on 4.1.1
Also make sure your wifi isn't getting turned off thru Asus power saver settings or another battery saver app. Flaky wifi routers or congested local wifi traffic with overlapping bands (channels) are notorious for randomly disconnecting wifi, but if its only after the last update then that probably has nothing to do with it unless your neighbor just installed a wireless router on or near your channel. Wifi Analyzer is a great app for weeding that sort of thing out.

I have the same problem with both my home router (Typically less than 10 feet away) and with my mobile hot spot. It started having this problem on each different network in the same time period, so I've ruled out the router. I've also now noticed that it does get worse with time until I can't even connect until I reboot.

I've done a quick scan of my nearby networks just in case, and since I am typically within the ten feet of my fairly powerful router, it's got a good 40+ dB on anything nearby. I also have the problem on my cellular hotspot in different places, so I'm ruling out the router.
I'm running only the stock power saver setting, I'll try shutting that off next time it starts again, to see if there's any effect, but the WiFi doesn't shut off, it just stops functioning correctly.
I've also come to find that the problem gets worse with uptime, 20 minutes ago I was getting 20 sec connections, until a reboot, now I expect to have hour+ functional periods.
I know what a cold boot is, but not completely familiar on this kind of device.
Do I need to shut down and leave it off for a few minutes to perform a cold boot?
Also, what is an FMR memory clean, and can I do that without root?

Cold boot: shut it off. Hold Volume Down and Power until the tab vibrates twice. If you're on 4.2 you should see 3 icons with RCK flashing. Use Volume Down to highlight "Android", press Volume Up to confirm.
Tiny script upper left will read: Cold booting Linux
As far as I know you can only clear cache for individual apps, not system caches on stock without root...
This is starting to sound like a hardware problem to me.
If you're still under warranty I would contact Asus and see what they have to say.
A factory reset would be my last resort before sending it in.
Good luck

What is it called when you boot into bootloader, then just let the RCK blink for 10s, hit no buttons, then it automatically boots saying "cold booting linux"? How is this different than the Android, or is it the same? I'm on 4.1.1

I don't think that works on 4.2 anymore since it defaults to fastboot mode (for which you had to select "USB" on 4.1) when booting into the bootloader.

I think on 4.1 you had two options to cold boot: Boot into the bootloader and do nothing as you mentioned earlier, or select the Android and confirm with Vol Up. Both accomplished the same thing: cold booting Linux.
On 4.2 you have to select the Android.

Thanks for the info. That's what I thought, but just confirming. Thinking isn't good enough, you gotta know. Wouldn't want to go around telling people how to cold boot or that cold boot fixes something when that's not what I'm actually doing, but it seemed pretty obvious I was cold booting - the micro script tells you so and also that if you wait 10s it will just happen automatically, and I like automatic. What's that font size anyway, 1/4 point? You just about need a magnifying glass to read it.
Actually, I've never done it any other way. From day 1 it seemed self-evident, and the easiest way to me, yet all I've read about cold booting on this forum says to do it with the Android. I guess that is the "official" way. But since I'm officially lazy, I do it the easiest way! This is a rare example of being able to do the same thing two different ways on Android. Often there is only one way to do it, to the letter. Talk about lazy, I use rebooter app too. 1-click cold boot. Savin' the buttons for when I really need 'em.
[Edit] Hey, OP we didn't forget about you. FMR Memory Cleaner can be run without root. Its not your average task killer. Digs out some memory somehow. It must clean cache and delete logs. I use it once a week religiously.

Yeah! You wouldn't want to wear out those volume buttons! LOL
I guess, that's why they defaulted the bootloader menu to fastboot on 4.2. Booting into system was redundant...

Believe it or not, my power button already stuck once in the down position. Talk about a boot loop. All that buzzing scared the daylights out of my dogs and they were just about ready to attack my tablet laying on my bed. I thought there was a raccoon or something in the house - they were going ballistic. I had just turned it off and set it down, and went out to the garage to work on a project and the next thing I know all he*& broke loose. I fixed it with a drop of electric razor oil on a Q-tip and my device is less than 6 mos old. I'm not joking about saving those buttons!

The common understanding of "cold booting" is "turning on the power and letting the bootloader load the kernel". So you are already cold booting if you turn it off and on again.
Nobody came up with any evidence yet that the explicit selection of Android in the bootloader menu does anything more than simply not entering the bootloader menu and letting it boot normally.
I noticed some interesting behavior when this happens on my device. Say its tethered to my phone's 3G, and there are up to 5 bars (pie slice shaped concentric rings) in the docked notifications panel on the lower right screen. Often my phone has 3-4 bars, but there are none showing on the device when this happens. This isn't ability to connect to wifi, it is connected, its ability to connect to the internet thru the wifi. I see this more often lately for some reason. I have to toggle my wifi or reset my hotspot so the bars come back on the device, and to re-connect to the internet. Happens often when I am posting here and there has been significant idle time between data exchange. Sometimes I can just highlight the address bar link and then hit enter and it reconnects. Seems like some kind of idle timeout. Maybe it has something to do with Verizon's hotspot connection and dwell time, and they are cutting off my allocated bandwidth connection so an "active" user can use it. Fine, but it doesn't reconnect me when I later transmit my data and that's not fine.

Maybe it has something to do with Verizon's hotspot connection and dwell time, and they are cutting off my allocated bandwidth connection so an "active" user can use it. Fine, but it doesn't reconnect me when I later transmit my data and that's not fine.

That would make sense, if it was only my hotspot where I was having the problem, but it's the same on my WiFi at home. I also believe that the bars on the Transformer WiFi dock notification indicate WiFi signal strength.

Cold boot: shut it off. Hold Volume Down and Power until the tab vibrates twice. If you're on 4.2 you should see 3 icons with RCK flashing. Use Volume Down to highlight "Android", press Volume Up to confirm.
Tiny script upper left will read: Cold booting Linux
As far as I know you can only clear cache for individual apps, not system caches on stock without root...
This is starting to sound like a hardware problem to me.
If you're still under warranty I would contact Asus and see what they have to say.
A factory reset would be my last resort before sending it in.
Good luck

Ah, wasn't sure since the small change after 4.2, thanks.
I've been afraid that this would be a hardware problem, I've kept this baby well, and thought of trading it in for a refurb is not a pleasant one...

Ah, now that I am looking at that again I think you are right. I thought they represented the 3G signal strength of the phones connection. What's interesting is that when it happens, the display is erroneous, because in wifi analyser app it still shows me I have 50dB yet the bar graph shows zero bars. Connected wifi with no signal strength. Yup, that's my problem alright.

WiFi issues?

Is anyone else noticing that their WiFi doesn't exactly drop, but just stops working apparently at random?
I notice this when sending a message via Hangouts, it won't send for a minute or two. Just three bouncing dots. My WiFi still shows connected, but the message doesn't send.
Same with Hangouts video chat. It will freeze up on me, and have a poor connection/experience, but when I switch to T-Mobile's network, no issues.
I haven't had this WiFi issue on any other devices in my home. (Droid Incredible, Galaxy Nexus, HP Touchpad w/Jelly Bean).

Tried turning off wifi optimization? That used to be a problem on my Gnex and I have it disabled on my N5. Not sure if it would help though.

I am experiencing the exact same issue. I just turned off WiFi optimization as suggested and we will see what happens.
Just received mine, I'll check it on my home Wi-Fi. My work Wi-Fi is suspect because the building is old and we've had a tough time getting things to work around here. Lol.

Artem Russakovskii posted on g+ that the nexus 5 has issues with networks that use a 5 ghz signal. Apparently using another channel solves the problem. Similar to the issues chromecast/nexus 7 has on 5 ghz networks. Changing it is worth a shot, most routers have an option to change it.
edit: (assuming you are using a 5 ghz channel)

This is good advice, thank you.
It's worth noting for my particular issue my router does not have a 5 Ghz band.

Just happened to me again with YouTube. Video stopped playing half way through. The only way to get the video to finish was to turn off wifi and switch to LTE. I had wifi optimization off, and I do not have a 5GHz router.

Even though my router is not 5 GHz I just went into my phones settings, WiFi, Advanced and changed the WiFi Frequency band from Auto to 2.4 Ghz. Maybe that will help? It seemed to work right away without me having to turn wifi off and on again so there is that. I need to use it awhile though.
Do you have any antivirus programs running? I had to uninstall mine because it was causing wifi issues.

I've been having some pretty terrible Wi-Fi reception. Especially on my school's campus. There will be a router on the ceiling directly above me, and I'll get like one or two bars maybe, and terrible speeds.
Just tried turning off Wi-Fi optimization, maybe it'll work better.
UPDATE: This seems to have fixed it. I just downloaded an app at 6 MB/s from the play store in the same spot I've always had problems.

I am having the same issue with my N5, there's a thread at Android Central discussing this issue: http://forums.androidcentral.com/google-nexus-5/329226-nexus-5-wifi-problem-4.html
Basically, if I watch a YouTube video that's at least 5 minutes long, I won't be able to finish it as the video will pause at least one or two minutes after starting. This is not YouTube buffering the video either, the video will just pause forever.
Another test is open up Chrome and type words into the URL bar. Auto suggests will appear, if I keep doing this, sooner or later there will be no auto suggest appearing, suggesting network connection is either dropped or became very slow.
I am connecting to an Asus RT-N16 router in 2.4Ghz N mode. Tried turning off Wifi optimization, and other router settings (20Mhz spread, G only mode, other frequencies, etc) and same problem persists.
Since this problem is not as common, I am suspecting this maybe a router incompatibility between N5 and Asus Rt-N16. Anyone reading this thread, if you are having this (or not) issue, please post your router model + settings. Thanks.
I have (2) N5's, a white one and a black one. The black one is very "flaky" with regards to wifi and battery drain. I initially noticed the problem with battery drain where it would drop 20% in two hours with <1m of screen time. It would also go from 100% to 4% over the course of a day with <50m of screen time. I initially did not use the phone much as I was trying to figure out the drain problem, but now that I have been using it more, I've experienced wifi drop outs, where the signal indicator shows connected with a strong signal. I have never experienced that amount of battery drain or any wifi problems with the white one. Both connect to the same routers. I have an Asus 802.11AC router at home. The only AC devices I have are the N5's and my laptop, but the laptop and white N5 has never had trouble. At work I have several TP-Link 802.11N routers in the ceiling throughout our building and a Netgear 802.11N router in our IT sandbox lab. I've tried changing channels, 2.4 vs 5Ghz, updating router firmware and performing factory resets on my home router and the Netgear at work, all to no avail. I've done factory wipes on both phones many times trying to find some reason for one to behave in such a way where the other does not. All I can come up with is that the black one is defective. What's worse, some days the black one will work just fine on wifi and I'll see expected battery drain.
Another update: I went to Paradise Bakery (sandwich shop with free wifi) to test out the wifi. The N5 connected to the wifi fine, but unable to get pass the 'Agree to EULA' login page. I brought along my work HTC One and it was able to connect and get pass the agreement page with no problems. I am beginning to think there's something wrong with the wifi on my N5.
