Weird WiFi question - Nexus 7 Q&A, Help & Troubleshooting

So I took my n7 to work today for the first time and it automatically signed in to or secured WiFi without me putting in a password. I subsequently took it to two other locations that have password protected networks and it automatically connected. All the of these locations are places that I HAVE taken my gs3, my question is this....are these WiFi network somehow remembered by my Google account or something? If not, how did the n7 connect to them? I am certain that these networks are password protected because I have used them before on other devices. I am also certain that my n7 has never been connected to them before because I have only had it for a week. Any help would be appreciated.

Tether N10 to phone via Bluetooth?

So when out of WiFi area I've previously just tethered my old tablet to my phone and used the phones data connection via the dial up networking profile. I can't for the life of me figure how to do this on the N10. Any ideas?

I can't answer your question, but why not just use the wifi hotspot?
Unless of course you are using a phone that does not have that feature ...

Fair question. Two reasons really, 1) some Telco providers and/or devices don't support it, and 2) it usually doesn't work internationally whereas tethering using DUN does.

Wifi issues.

So when I lock my Nexus 7, my wifi will drop after a minute or so, and in order for it to stay on I have to keep the screen unlocked and on. Does anyone know what I could do to fix this? Thanks.

Should have clarified, I have it set to stay on.
This is a well documented issue and has just happened on 4.2.1. I have the same issue and looking for a fix
Sent from my Nexus 7 using xda app-developers app
I'm stock rom, rooted, cwm recovery, 4.2.1. My wi-fi is rock solid perfect. Some issues that have caused problems are the encryption method (wpa seems best), too long or special characters in the network password, outdated firmware on the router, reset of router needed, static ip seems to help some.

[Q] Nexus wifi issue [HELP]

i just picked up my nexus 10
got home connected to my home wifi (works on my nexus 4, nexus 7, galaxy s3, htc one x+, htc g2, xbox, laptop)
nexus 10 connected to it but couldnt launch any webpages? or even sign me into gmail?
turned on my phone hotspot and my nexus 10 connected fine and loaded webpages with no issues?
unlocked and rooted my nexus 10 and flashed paranoid android seeing if maybe a 4.2.2 would fix this, but still no luck
my nexus 10 connects to the network but its like it doesnt have a connection?
anybody have any ideas or solutions for this?
i would appreciate the help!
Any ideas?

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.

i read somewhere same issue with arris router http://www.nexus7nexus10.com/forum/nexus-10-discussions/3007-nexus-10-problem-5.html
The quick fix I found for this problem.
Download connectify me on your pc broadcast your network under another ssid.
And my tablet works perfectly fine connected thru that
I'm still going to swap my router though
Sent from my Nexus 4 using xda premium
Any real solution yet? I have the same problem, my device connects to most of the wifis except the one I use at home. I got 2 actually, one router in my room and one in my dad's, the one in my room mostly never works.

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.
Sent from my Nexus 4 using xda premium
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.
That may be interesting: http://ir.arrisi.com/phoenix.zhtml?c=87823&p=RssLanding&cat=news&id=1807670
Summary: Arris has bought Motorola Home and has associated with Google.

Same here. It seems to be only my router that it doesn't connect to. Manta is dead I'm afraid

No WiFi at all

Hey all, I have the WiFi only 8gb model and just as of recently it cannot connect to WiFi AP's. It has the ability to see signal strength of AP's but the WiFi icon in the status bar remains empty an and it can't authenticate to either the home router or my phone as a hotspot.
NFC is off, device is rooted, tried wiping everything, no gaps cracks or bumps in back cover, etc...
Anyone have any other suggestions?
Thanks

Try using WPA/WPA2 PSK encryption is you are not already using encryption.
What's changed? Now ROM? New router? New software installed?
Sent from my Nexus 7 using Tapatalk 4 Beta
Nothing, I haven't used it since July 4th. Now visiting my patents and it won't work with either AP. Unless it got damaged on the flight out but it was with me the whole time.
Also yes both are encrypted with WPA2.

Google Wallet Tap & Pay for Kit Kat: How to get it to work on N7!

Tap & Pay now works for Google Wallet for N7 Kit Kat.....IF you get the Nexus 5 version of Wallet!
Which you can find on Phandroid here
Instructions for n00bs: To install, download the .apk file at the webpage link above. MAKE SURE UNKNOWN SOURCES IS CHECKED IN YOUR SECURITY SETTINGS prior to download.
Then run the app and follow the directions in the app to setup Tap & Pay.
Make sure NFC is enabled and you have an internet connection when attempting payment (have the Wallet app showing when you are ready for payment.)
I just bought McDonald's with it....using their WiFi!
Sent from my Nexus 7 using XDA Premium HD app
thanks and yes, after installing that apk and setting it up, Wallet does now appear in tap & pay. I'll try it out. Thanks
I seem to remember a blog post and thread here how NFC could not work with Wallet on the new N7. I disagreed because the hardware is there and the security can be emulated in software. This workaround proves it. I'm going to McDonald's tonight .
Thanks

Are you sure you need an internet connection when attempting payment? You didn't with the 2012 N7.

How can you make a payment without an Internet connection? :what: If that was the case, you make a payment offline, factory reset your tablet before it connects again. In theory, you won't get charged then, right?

No. Your device communicates your payment data via NFC. The element receiving that data actually executes the charge. Your device doesn't need to connect to the internet anymore than your credit cards need to connect to the internet.

I understand now. The NFC chip replaces your card, it's equivalent to swiping your credit card, got it, thanks buddy.

...thought the app told me to have an internet connection. How else does the app retrieve your credit card info?
Granted, it COULD be stored directly in the app...but then that poses a security risk, I would think

Almost as risky as storing your credit card info on a plastic card in your billfold. Someone nips that and they have all they need to charge your account!
Sent from my Nexus 7 using Tapatalk 4
Guys you CAN pay without an internet connection. The Nexus 7 2013 works the same as the Nexus 5, using HCE instead of a secure element. I tried my N5 in airplane mode (with NFC switched back on) a couple days ago at CVS and it worked fine. As soon as I turned off airplane mode the transaction details downloaded.
Now while the transaction will work without internet Wallet now requires an internet connection to PIN unlock! So if there is no service in the store unlock it before going in. If you're feeling more daring you can use 1 day or no PIN timeout for wallet and not have to worry about internet connectivity.

One of the new features in KitKat is 'virtual smart cards' which allows them to take the credit card information and essentially create a virtual card that has the same content as your real card. It's protected the same way as your credit card does it. Tap and Pay is actually identical to "chip and pin" just done over NFC. So this duplicates the 'chip' part.
Any way to make this work outside the USA without any crazy hacks?
