Sony Z2 Tablet WiFi Only (SGP511) forces disconnects from Hotspot without Internet - Xperia Z2 Tablet Q&A, Help & Troubleshooting

So i have a customer that has bought a product from us. This product takes data from your boat (position, speed, wind, depth etc.) and transfers this over WiFi to wireless devices. There are apps that can make use of this information to turn your device into a navigation tool. My customer has installed this on his boat and is trying to connect his tablet to it. As there is no internet from this source, the Tablet will connect to the hotspot and then immediately disconnect. This is due to the software on the tablet deeming the source not good enough and will say "Avoided due to poor internet connection".
He let me know his fault and I looked through my settings on my Z2 tablet, which is the WiFi/LTE version (SGP521), i found an option to stop my tablet disconnecting. I called my customer and guided him to this option, only it wasn't there for him. I have asked him to update his tablet to the latest version, but still no option is found.
Sony have been very unhelpful, they said to find a third party app, i found one, but it requires rooting, which i cant ask my customer to do.
I told Sony this and asked if they can recommend something. They said no and that was the end of our conversation. Very helpful.
I know that our product is not the only one that generates a hotspot without an internet connection. I think the GoPro works the same way.
So my question really is, does anyone know a non-root way of connecting to this? Whether its an app or a hidden setting somewhere.
Thank you very much for your help.

[Q] Tethering with rooted ICS phone

I have searched extensively on Google, and XDA but can't find the right answer.
I want to tether my phone. I can do this directly in Android but my current carrier brings up a message in the browser saying it's not supported on my current plan.
I'm addressing this, but in the mean time I'm curious if there is a way round it, hypothetically.
I have seen some Apps, such as ClockWork Mod Tether, but since my phone is rooted I wondered if there is a more elegant solution that doesn't involve any software to be added to my PC.
I read about using TB to freeze a specific App/Process but couldn't find any details.
Any advice would be great,
thanks

HOW have you not heard of android wifi tether? One of the first reasons I had for rooting the first Android phone I got.
There's also Barnacle Tether, available on the play store.
Guess Barnacle is gone... but there are other tethering apps on the play store though.
And I'm wrong again. Barnacle is still there, but doesn't show up when I search from my phone. How curious.
Since your phone is rooted you can download wireless tether.
Google it and you will easily find the download link or even directly via the play store.

I appreciate the reply, but if you read my post again the issue I'm having is not an app to enable wifi tether directly on the handset, it's that the packet data is being detected as not from the phone so I get a message, on the computer, in the internet browser saying my priceplan doesn't include tethering. I cant get around this 3 website redirect. So, I need a way to tether, without the network knowing... The apps you mention work when the block is at the phone level I believe.... This is something different Three is doing..
Please correct me if I'm wrong though...
Oh, and as for the apps not showing up, the mobile phone providers asked google to block these apps for certain customers.. if you connect to a wifi network when in flight mode, and go the google market, you should still be able to see them...

I WAS on wifi.
And did you ACTUALLY download the tether app and try, or were you using the tether built into the settings of Android? Because it sure doesn't sound like you downloaded the app...
And I don't have tethering on my carrier plan, but the tether app works just fine for me.

Initially when I first posted I was trying the built in app but I downloaded the app you suggested anyway, but it didn't work. would connect to the computer but no data connection. Unsure if its an app problem or still a three problem, but I don't see how this app would fix the three problem. Does it somehow mask the PC data connection??? I couldn't see anything in the settings or set up that suggest that it would, it just looks like a more feature rich wifi hotspot app?? In addition I found mention that that others with my issue have also tried these apps like barnacle and it didn;t resolve the problem....

They can suspend your service if they discover you are doing tethering on your device if you are not alowed in your current plan.
I Hope you wont have any issues.
Otherwise it is possible that the sim card lock the feature even on rooted phone when detect thetering or it is impossible ?

yes I suppose they could do, but like I say I'm resolving this with my contract. It's more that I'm curious how they are doing it, and on principle don't like being told what I can and can't do
It can't be a sim lock.
I just tried tethering a Macbook, and amazingly that worked!.. SO, It must be something to do with the Packet Headers I'm guessing.. Or they are doing some other more detailed packet sniffing... It means there is definitely a software route around it... Need a clever developer to read this thread
I guess clockworkMod Tether might work, but I want a solution without a PC install..

That doesn't make any sense. If it works with a mac book, it should work with your windows machine too. Unless your windows machine has some kind of proxy?

When you use thetering, you embark to the provider internet network.
for example my provider is Bell Canada and their proxy is web.wireless.bell.ca
this one is for the device internet
for the thetering one they use another configuration settings when i connect my device to the computer.
What happen is when you plug your device to the computer, a signal is sent to the provider stating you entered in thetering mode. You don't have access to thetering so your internet connection is limited to the walled garden of the provider stating you are not subscrided to the service. Thats why i think they blocked the port 80 on your device and redirect you to that page.
Now for the Macintosh story.. It is not impossible that you can connect without problem with a mac and safari. I know a lot of people emulating a handled device with the Mac and the safari browser and those peeps didnt had a thetering plan.
The differences came with the drivers installed. Mac OS one are quite different in term of functionality than windows, thats why maybe the provider is able to sniff more easily people using windows but i am not a senior programmer. I am currently taking courses to become one but for now it is only suppositions. If i am wrong feel free to correct me but I am quite sure about what i am saying and that's why you dont have issues with a mac

This sounds correct to me. I'm pretty annoyed though. Only had the contract a month, I was told I could move onto a more expensive plan within contract if I needed more allowance etc.. Phone up 3, not only do they not let you PAY MORE for a different plan, but they also don't let anyone shift onto the one plan ever, unless its a new contract.. So basically **** them... so even if I want to pay extra for tethering I can't... absolute nonsense...
I had the same issue with three. I downloaded masqued crusader from play store. Activated it and then started wireless/usb tether. It worked. That was a while back tho. On a payg sim card on a galaxy s on gb. Its worth a try though.

Hotspot not supported - how does carrier know?

With the sim in my phone, I get the net on my phone.
If I put my sim into my tablet, I could get the net (if the touchpad had 3g).
But if I try to use the phone as a wifi hotspot, the carrier knows the data is being shared, and blocks it. How does it know?
Am now wondering whether any of the apps to share the connection - eg over Bluetooth - would be the same or not. Must try it out.
Find it very puzzling (until the carrier told me that I could share the data connection over a wifi hotspot on my phone... if I agreed to pay them more money)...
apologies, thought would be of interest to users, appreciate developers are above stuff like that..its why i posted in the general forum. i did search but didnt find the relevant thread. this isnt a very friendly forum for users, i have noticed a few threads that interest people being attacked.
What method are you using for mobile hotspot? Phone, ROM, app, etc.

I have ran into problems using wifi tethering methods with Verizon in the US. When I tried to tether, I would get a page in the browser, on the device Im trying to get connection on, of verizon saying if you want to tether, you have to pay for it. Something along those lines. If the wildfire puts out an adhoc connection, most tethering apps wont show up on the TouchPad since it does not support that type of connection. The one app I have tried successfully is PDAnet in the play store. I have installed CM7 and CM9 on my phone and both built in option works with the TouchPad without the carrier noticing. Have you ever tried installing a different ROM on your phone. I dont know whats available for your phone.
EDIT: Sorry, If you're phone only goes up to froyo, I guess CM7 and CM9 are out of the question. But there may be others.

Just know, you need two apps. "PdaNet Tablet" on the TouchPad and I forget the name of the app for the phone. I think it tells you on the tablet app when you start it.
EDIT: Just read you need the phone version of PdaNet or another app called Foxfi on your phone.

why do you click it and then decide to post what you have....its the general section. if you're solely interested in development then here's the link HP Touchpad Development
I'm not too sure how the carrier finds out, maybe larger number of data packets compared to data being received by the phone (regardless of desktop sites being requested).
I see that you're with Orange, and if they follow the same rules as T-mobile following their merger, then they don't fine you for going over your allowance, they just limit your usage to off peak hours....then a warning...then disconnection of your data service. Only phonecalls and texts.
I know this because I totally rinsed the allowance in 2 hours after my wifi went down and I had work related files to download.

there are many ways that mobile device is different from a pc
minutes differences in the way packets are sent/created/received/acknowledged differ from os to os, not to mention hardware
obvious one are mac addressing (easy to spoof but you can usually tell if the mac is a pc or mobile based)
User Agents as was mentioned, although this not a all defining as browser apps can spoof this
and im sure there many more, all of these create a system fingerprint that makes you different from all the other devices on the operators network

to be fair it could've belonged anywhere from wildfire to touchpad to just general android Q&A.....lets just be happy he didn't post it in development. I'd be thinking just as much as to where to post it, besides a touchpad solution might differ from other tablets seeing that it is a bit "unique"
I currently use "WiFi Tether" from the google play store on my "rooted" HTC to connect my Touchpad and dont have any issues with surfing.
But as darkassin mentioned, with some plans, after a certain amount of data used, you may or may not have your service slowed down. i have encounter this with downloaded nightly ROMS...I stopped doing that till i get home and use reg WiFi.
Enjoy.
Am on classicnerds here and a number of GB and ICS ROM's on a HTC phone. Hotspot works OK with laptop and TouchPad. Had to use the APN fix to get around the carrier blocking the tethering.
Focus should be over in your phone forum.

Nexus7 android 4.0 web login problems with open network

Hi. I have both a nexus 7 as well as an HTC evo. Neither device works with my work open wifi network. The common thread is that they are both android ICS devices. The network is open but requires the user to accept an agreement before use. Both devices connect to the network, but never bring up the web agreement/authorization page and eventually simply time out.
I really need to have wifi at work and will likely sell the devices if I cannot get them working. I really don't want to do have to do so. Please help!

I had the same issue on my Guingerbread, download an app called wifi fixer that worked for me every time it runs as a service in the background and keeps the wifi active.
Does anyone have a solution? I literally will sell this tablet if I can't solve this issue because I'll be working at this place for at least 3 years and need wifi access.
Is it a certificate issue? An IP issue? Please help
The issue isn't a dropped connection. It connects fine but never brings up the authentication page. Instead the phone does nothing because its dependent on wifi data once it has a full connection. *BTW i tried wifi fixer. it didn't help

[Q] Android Phone as Router (Please read for more details)

Sorry if the title is ambiguous. This is what I am considering.
Scenario:
I have a router at home that is password protected. I frequently have guests coming over and sometimes, they need to have access to the Internet. My current situation/setup will result in me having to provide them my router password. The connection settings are then permanently saved on the guests' devices.
Desired Scenario:
I wish to use my Android phone (preferably Android 2.3.3) as an in-between. I would like the guests' devices to connect to my Android phone while the Android phone connects to the router.
As such, the guests' devices will only see the Android phone acting as a router.
Doing so will allow me to maintain the password of my router as a secret, while giving me more flexibility in deciding what each device (perhaps by MAC address?) can do.
Question:
Is this even possible?
If so, could someone point me in the right direction?
Background knowledge:
I have very limited knowledge in Networking but am always open to learning new things.
I am generally strong in C language and am new to Android programming. However, I can pick things up on my own once I have a clear direction or reference that I can use.
The reason for targeting Android 2.3.3 is because this is the current version on my Sony X10 Mini Pro. The speakers have died and now it's just a piece of device sitting on my table.
I want to make it more useful, so I am exploring other possible functionalities.
As of now, it is configured as a webcam but I'm still trying to get it to work with Skype.
Thank you very much =)

Hi! Sorry for reviving a relatively dead thread.
I ran into a bit of a problem.
Most of the apps assume that I have a mobile data connection.
My phone does not have a mobile data connection and so it is unable to tether.
What I would like is for my phone to connect to my home router while accepting incoming connections from other devices (phones, laptops, etc).
Basically I want it to be acting as an intermediate router, as shown by the simple diagram below.
Router <-------> Phone <--------> Other devices
<-------------> is Wifi connection.
Hope it's not impossible.
Thank you =).

Is it possible to connect multiple phones with bluetooth and use one to make all call

Hi,
i may have a strange request.
Currently i have 3 different mobile phones and find it difficult to manage them properly.
I have an iPhone, OnePlus One and a new testing device from a carrier. I use iPhone as my personal number and OPO as business number. 3rd phone is for testing LTE networks only.
Will it be possible to connect these phones using bluetooth so i can call from a single phone say iPhone or OPO (actually call from other phone but manage it from single phone only?
I tried searching online for something similar but couldn't find anything useable. If someone has some idea on this then that would be really helpful
Thank You
its not possible dude....!
It's not possible directly, but you could try remote control apps. There's several available in app/play store, where you can remote control one device from another. (Many based on VNC)
Not over bluetooth though. They work over wifi.
might be possible in future
Yes, you guys are right. This does not seem possible at this time but in future we might be able to do something similar.
found this link with a kickstarter project which will be doing same thing over bluetooth. Couldn't post link due to my account being a new one. But if you can search for "piece sim card bluetooth adapter" you can get articles on this tech.
