Anyone else having wifi connection issues with 4.2.1?

I only got my n7 a couple of weeks ago and almost immediately updated to 4.2. I didn't notice any issues. Immediately after the 4.2.1 update I keep getting random connection issues. I have to turn wifi off and on to resolve it.

I had the issue.. 32gb version in the US with the sep build. I actually had it prior to to 4.2.1. I ended up going into advanced properties and changing wifi to always on. Drains battery, but fewer need to turn wifi off and back on.

Yes. I have WiFi disconnects and random reboots since the new update .

WiFi Fixer
I use WiFi Fixer downloaded from Google Play. When the connection is dropped it automatically reconnects after a second or two.

Same on my 7 WiFi stops working at random times turn WiFi off and on fixes it, only started after 4.2.1 update

How do we make Google aware of these bugs?

My WiFi is always on and tethered to my evo3d at least 8 hours a day. Not a single problem under 4.2.1.

Just to clarify, i'm having this problem 100% stock. Not rooted what so ever. Roms/kernels could have this eliminated. But I wouldn't know.

No wifi internet / e-mail / notifications after 4.2.1
I am having a similar issue. Stock Nexus 7, never rooted, installed the 4.2.1 update when it was pushed. Since then I can connect to wifi connections but there is no internet access. While the icon in the upper right has small flashing arrow like data is being sent back and forth, the icon remains gray and no internet-requiring services on the tablet work. I've tried everything that I (and Google Play and Asus support) could think of with no luck.
The only thing they could come up with at the end was to restore the tablet to factory settings. Unfortunately I have application data that I need to back up that I can't access by accessing the internal storage using my laptop (I'm stock, remember?).
So I'm between a rock and a hard place here. Anyone have any suggestions? It was very frustrating when the Asus representative suggested I use the built-in backup and restore feature:
Me: "That requires internet access to work right?
Asus representative: "Oh....right..."

My Wi-Fi on both my Nexus 7's is very slow. They stay connected fine but I'm getting about 150kbps download speeds. I factory reset one of them to no prevail. Anyone have any insight on this or heard of others with this issue? All my other devices work fine on the same Wi-Fi connection and I tried turning everything else off so just the Nexi where connected to see if the speeds are faster, but they aren't. I'm stock on both devices and both are the 16gb version, one older than the other.

Known issue. I logged a bug with Google and there's actually several open bugs reporting wifi issues. So far, none of the bugs are being picked up by google officially.

I've tried this same thing, and as soon as I installed 4.2, WiFi went to sh**. Completely stock.
So turning wifi off then on seems to be the generally excepted quick fix?

Or use Static IPs. That solved it for me. I had to ask my company to provide a reservation for my MAC Address. It's like back in the 90s when Wifi started coming out using the BellLabs/Lucent chipset.

Why no bluetooth tethering on Telus?

Im not sure why it isnt on the s4 its my biggest let down with this fantastic phone. I did a few search's i havnt seen any fixs. Why has this been removed?

Why would you want to? Hotspot is all you need.

I found it uses way less energy then the wifi hot spot.

Im suprised more people havnt complained about it. With a non mobile network nexus 7 it was very good. Im guessing they took it out cause of slow speed but it still worked great for navigation

Every time you turn on your WiFi you're being logged and tracked.
Spy agency tracked passengers for days through free Wi-Fi

That's why your carrier allows for WiFi tether but disable Bluetooth tethering to encourage users to use wifi and be tracked by the government.

[Q] wifi problems

hi everyone....used to be a regular on here when i had my captivate, but then the s3 and my current s4 i never modded in any way......anyway...my att s4 will not keep my home wifi info and loses connection at times....is there any way to fix this?

If it only happens on your home Wi-Fi it's an issue with it. Try upgrading the firmware on it.

no
it has to be phone side becausee there are numerous things on wifi that are not effected

Few questions first to help,
Is your router a single or dual band router?
Does it drop and than reconnect, or is it dropping and not finding?
Sent from my SGH-I337 using XDA Premium 4 mobile app

it drops and then i have to retype the password
i think it is dual band

WiFi has been crap on my s4 since day one. Constantly drops or slows significantly on N or AC or G networks. I tried 3 routers and I have dozens of other devices with no problems. Countless times a day I have to toggle WiFi on and off to restore speed for another 5,10 or 15 minutes. YouTube is the worst. It just hangs when the phone drops to 1-3 Mbps down from 30. This happened on stock and all stock like ROMs. WiFi is this phones tragic flaw. The problem gets no attention online because people think it only pertains to dlink routers which is completely untrue.

well
well i figured out my problem i think...it may be your problem as well
is yours on att as well?
if so there is a app called att smart wifi...this is what was causing my issues....however the phone(even stock) will let you remove this app

I am on att, I don't have it. I have something frozen called ATT hotspots. But nothing called Att smart WiFi.

D801 Slow wifi

Hi
So lets get straight to it. Im rooted using IO , freegeed w/twrp, running stock rooted 10g rom. I have tried several roms and none of them on a speed test show me able to get over 3.8 mbps yet I get 8 mbps upload. I checked my pc, 30+ mbps download on there. Checked my gf's (completely untouched by me lol) g2 and she has the same problem its like it capped at 3.8 mbps on the wifi. 4g im getting 30 mbps. I am using comcasts phone/modem/router pos and when i checked i saw its 2.4ghz so i selected 2.4ghz on the phone along with turned wifi battery saver off. I have pretty much tried all I can think of. So now i need your help! I switched over from my lg og to the g2 and the og worked fine on this router.

Maybe try changing the channel on your router to 11?

thanks for the reply, but did not work.

Is it an old router?Try your phone with another router.

I'm guessing since its Comcast crap and only 2.4 ghz no 5 option that it is old. Lol. Just not sure why my og worked fine with this router, my brothers og pro is fine. But not our g2's

I don't need to go anywhere today and its cold out I don't want to just go to see atm. I'm wondering if I use my gfs g2 as a hotspot if I could see if wifi works that way. To bad she's at work lol
Sent from my LG-D801 using XDA Premium 4 mobile app

Cool, gf came home, turned on mobile hot spot, 30 mbps. So it is this pos Comcast router. I wonder if I call them if they will give me a newer router. But is there a special feature needed by a router for these phones? I'm confused lol. Why only g2's on this router?
Sent from my LG-D801 using XDA Premium 4 mobile app

@ripbabey Turn to WPA TKIP only. The G2 hates the Technicolor AES+TKIP combo. Fixed mine. Weird thing is, works fine in AES on my SB6141 and the Arris. No further idea about it. Something just isn't getting along between the two. I'm not technical enough to dig deeper.

I'll check that out thanks
Sent from my LG-D801 using XDA Premium 4 mobile app

You're welcome. It will work. I about returned the Technicolor because of this.

That actually improved some speed Mr not technical enough lol. I'm getting 12-15 mbps now which is matching my computer. So now when my speed picks back up from Comcast I'll see if I get any higher. Thank you so much!

I was getting over 20, which matches, winter weather is hindering my connection. How I miss underground wiring.

Lol. So far so good, was about to just go get a router. Now it looks like I don't need to.

Wifi issues do I need to switch while I still can

I just got the s4 and its total stock but it keeps dropping on and off wifi. In fact in settings it sometimes says I have poor wifi conection. But I know my router is good and my wifes g2 has no problems. I read online there is alot of issues sinve the 4.3 update and even after the patch. I also read samsung is not going to do anything there blaming sprint or your wifi. Should I switch to the g2 while I still can or hold out for a fix or does anyone know a fix?

Also it took 4 hours to set up phone. Most was the crazy slow download of apps from play store and updates from play store. Small apps would take 10 minutes to download then about 5 to install while on my wifes g2 same app same time downloaded and installed in under a minute

WiFi switching on and off is probably under wifi settings. Just turn it off and it will stop switching on and off.

I tried that even did the ##code to get into WiFi and turn off WiFi saver. Nothing worked and then it started saying no mobile data connection but I was on lte and it worked. Plus I was getting that Knox problem so I just went to the g2. Thanks though
