VPN L2TP connection issues reboot - Nexus 7 Q&A, Help & Troubleshooting

Hello all,
I bought my Nexus 7 in Hong Kong. Now I'm back in Mainland China and faced a big problem with the VPN L2TP connection on my N7. After the VPN tunnel is established my N7 reboots after an undefined time. I'm able to download and use it...but then the device freezes and reboots. Staying in China without VPN (PPTP is mostly slowly and blocked ) is a mess. Somebody has an idea or faced the same ?
On my Nexus phone I've no problems...

I have EXACTLY the same problem! I log in to my VPN on the Nexus 7, then - at any moment either immeidately after or sometimes 20-30 minutes after - the thing just reboots itself randomly. Does NOT happen when VPN is not connected.
Talk about annoying!

Ok... I'm back in China...so...VPN must have....I've tested several things...WPA2,WPA and WEP...it doesn't matter...device freezes and reboots...that's absolutely a bug in the N7... somebody knows how to send that to Google devs?

I just wanted to comment that I get the same exact reboot issue, although mine could be attributed to the ROM I'm using which is Bugless Beast.
I use L2TP connections too, but mine will reboot immediately after opening chrome, or other programs which use the Internet. Not sure what to do

Sure... possible if you root your device...I've solved it flashing my rooter... running there an OpenVPN client...still 4.2 got that bug...painfully enough for Google... other OEM's don't have such struggling behaviour... Regards from Changchun...with the smallest bandwith of China....really annoying...

similar but
On my device, I connect to VPN at home and at work. I have never had the restart bug when I connect at work. It always happens when I'm at home. So this is a very specific bug for a certain kind of connection and not just VPN WiFi in general. Good luck everyone I hope we figure this out.

Which vpns do you use here in China?
I am having trouble setting up Witopia on my nexus 7. I have it on my computer and it doesn't work very well and I have it on my ipad but no luck on the nexus. Why are the android settings far less user friendly than apple's?
What vpns are you guys using? Are any of them free? I want to change the region on my nexus to download apps from the US.

Hi...they are User friendly...but there are with some VPN Providers telegram issues since Android 4. Some are able to handle it, some not. I´m using Astrill. It´s cheap, fast enough, great support and a lot of server locations. Sorry, i wasn´t able to get any VPN connection without reboot of my Nexus 7. My solution was to invest some money in a new router, which i flashed DDWRT and put from Astrill the OpenVPN solution on it.

Hi all,
I was Bord the last days...and...i've flashed my Android devices with custom roms....my Nexus 7 has no VPN issues using Paranoid Android Rom...now i'm pretty sure that anything in the stock Rom is a mess....

Download failure issue help

I have ever since I got my Nexus 7 I have also have this problem with my Transformer Prime where i try to download something but 99 percent of the time it fails, so I have to go down in the download app and hit retry repeatedly until it downloads correctly

Have you tried this on different wifi networks? It sounds like your connection is probably not reliable.

Switching to WEP may solve it
I'd really like to help but i don't have much time right now. But i can give you something to start.
1. I'm not sure but N7 may not have all wi-fi modes because of production costs. Wi-fi b/g is there but no a/n. Maybe it has something to do with this. Your router could be broadcasting on a or n or something. Actually i'm not good at this. I'm just trying to give you some leads.
2. Setting your wi-fi password to WPA could cause some problems on some devices, not only N7. I've seen it on laptops, phones, some unimportant wi-fi enabled devices. Maybe if you could set it to WEP, your download problems could be solved. I don't have a N7 but my download problems solved everytime i switched to WEP.

Wi-Fi connectivity issues with 4.2.1

My Wi-Fi connectivity was rock solid on 4.2, but since applying the OTA I'm getting frequent data drops. Still shows me as connected to my router, but get no data. A quick Wi-Fi toggle fixes the problem each time. Anybody else seeing this?

Does anyone else have this issue ?
Connectivity is really key for this device and if this is common then I would likely not update.
upsetting to hear this, one of the big reasons I opted for this over some other 10.1in tablets was the MIMO dual band wireless. My Viewsonic g-tablet has horrible wifi connectivity and it makes watching youtube horrible. I couldnt imagine having to deal with it on my nexus 10 when it comes in the mail.
The first thing to check is always to set a static IP and see if the issue is resolved.
Just got my replacement today. Before the 4.2 and 4.2.1 updates, WiFi was solid no drops and full bars. After updates, pretty finicky drops quite a bit:/ hope the next update addresses this.
And yes sometimes it will show bars but no data. Especially when I start using 5ghz instead of 2.4ghz.
Sent from my Nexus 10 using Tapatalk HD
After a few hours with no drops, I may have discovered a fix for my situation. I changed my access point from WPA (TKIP) to WPA2 (AES), and for the last 4 hours I haven't had a single drop. Prior to this, it'd drop every few minutes. Hopefully this holds up.
I've been having connectivity issues as well. I'll have my Nexus 7 and 10 in the same spot and the N7 will hold a solid connection and the N10 will drop and reconnect ad nauseam
My Wifi is perfect.
I also have this problem , any one found a fix?

When I had this problem I found that my google account had saved my connection settings. It was trying to use the same static ip as my phone. Went in and changed it and everything is fine.

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.

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.

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.

I had this issue a few days ago and another guy just made a thread on the same thing.
Mine worked for a week and cutout. Exchanged it and the new one hasn't had any issues yet.
The other guy exchanged his twice before getting one that worked. Both of ours connected to other networks than our own. Not sure why some Nexus 10's connect and others don't. And who knows of the ones we got from the exchange will continue to work.

i found somewhere online nexus 10 has trouble connecting to ARRIS routers
just found out thats what i have
some firmware issue with the nexus 10?
thing is it shows connected to my home networks but just shows gray bars showing no actual internet connection,(no blue bars) only a connection to the router itself
im trying to find a way to assing an a static ip now. thats the solutions they found
all other routers i can connect to perfectly
Arris is what I have as well, Through xfinity. A day after I changed my first one to a static IP address was when I started having issues. Did a complete factory reset of the router and tablet. Couldn't get anything to work. I don't understand how it worked for a week and just stopped. Then reverting to all the original settings on both devices didn't help.
Maybe someone with more networking knowledge can give us a good answer. I'm really having trouble understanding how a different nexus 10 will work having the same settings and firmware.

No real solution. Don't think there is one I spent about an hour searching everywhere I could.
So far it looks like nexus doesn't like ARRIS routers (I have time warner,not sure about you guys)
But I'll be swapping out my ARRIS router for a motorola one this week and I'll report back here to let you know if it worked
That connectify me is working awesome though.

great find, sich its such a hot issue you should make a thread detailing how to fix it using connectify me and also potentially reporting it to google.

Strange behavior with text and lock screen?

Hi,
Ive just bought a brand new Nexus 10 and its doing really wierd things.
After updating to Android 4.4.4 i kept getting kicked off and the device would go to the lock screen. Additionally the screen would do strange things when running Chrome like going totally black with a white ring in the center of the screen.
Also text doesnt seem to display properly at times; i have now downgraded back to version 4.2 which seems to have got some stability back howver text is still broken on occassion.... See attached.
Its really odd as i have a Nexus 7 mkII which ultra stable.
Could this be hw related or simply is the rom simply this buggy?
Thanks for any ideas.

Ok so I updated to 4.3 and the machine seems to be stable minus the occasional logout when opening Chrome.... However text still has problems displaying; also as with Android 4.2 it seems the wifi kept disconnecting every few minutes. Since the AP being used was the spare wifi card in my Linux HTPC it migt have something to do with the Intel Centrino card at the other end. I have a spare 3com AP which I will try and if not I also have a spare Cisco wireless router which I can also hookup.....
Other then that I dont know???

Have you tried a complete wipe (flashing the factory image and doing a data wipe/factory reset afterwards)? Not sure if that's what you did when you downgraded. I would think a 100% fresh start would help.
Yep I did... Sorry if wasnt clear. I even reformatted the partitions.....
I think what bothers me the most is the incomplete text...... When downgrading I got the stock rom from Google directly.
Also something funky is the screen seems to slightly flicker when running the Plex app. This could just be an app thing though as everything else is fine.

Boy. This is a real head scratcher. I've never heard of this before. It would be one thing if the screen was static, which would usually indicate a loose ribbon connection. Since you've already successfully flashed the factory image, I don't think it would be software related. But I can't think of any hardware issue that would cause this either.

Ok good news.... Using my spare Cisco wireless router I got stability on the wifi
I'm just thinking that maybe the issue could be something to do with the graphics chip??
Of course if I dont need to i really dont want to but if it isnt a software bug and the issue is hw related perhaps I should just contact the place where I bought it and get it replaced???

Hi,
It is really bugging me, quite a weird issue. I believe it can be surely a defective unit, after all you flashed a stock ROM wiping completely and problems still persists.
I recommend you contacting the place you bought it. Hope you can get a replacement .
