[Q] LAN between two phones - Galaxy S I9000 Q&A, Help & Troubleshooting

Hi, I've searched for an answer but I didn't find anything relevant, so my questions is, can I create an wifi lan connection between two phones but without sharing the mobile data connection?

you mean then exchanging files through wireless, where the wireless LAN is established and maintained by the two phones and not by a 3rd device (router) ?

Exactly. But not only file exchange, I want rather to host a web-server on one phone and other phones can access it without having an internet connection.

I might be less informed than you, but then what is tethering about?
With tethering, the phone with WAN access (the tetherer) can share the internet to the phone without internet access (the tetheree)

It also shares the mobile data connection which I don't want. Maybe there is a way to start Wi-fi thetering without sharing the data connection?

Wi-Fi direct is what you are looking for, the bad news is that the sgs doesn't support it (to my knowledge).
Swype'ed on my CM10 Galaxy Nexus

Why not simply disable 'data' for mobile connection on server side?
Maybe you can control the corresponding traffic (port 80) with Droidwall.

I think this may be exactly what you want. It creates a local web server using the WiFi hotspot library so people can download files from your phone with a very to use QR system.

there are roms with wi-fi direct support. I was able using it with CM10

Thanks guys, I've solved it with the wi-fi hotspot option from cm10 & disabling the data connection.
And by the way, as a web-server I used Paw Server. It also supports PHP.

Using Kaiser as Modem

Hello there,
Im not sure this is possible so here goes..
I am using the works connection, however they have pretty much everysite blocked, so i want to use my phones connection (kaiser with WnW+).
Now if i unplug my works network cable i can browse the internet through the kaisers internet connection (Local Area Connection 10 on here) but obviously can't access my network drives.
Now what i want to do is have both my works connection and my kaiser in, but i want the browser to use my phones connection NOT the works connection, however i still need my network drive etc.
Sorry if i have confused you or you don't understand.
In order to keep your work's connection active at the same time as your phone's, you would need software for Windows that forces port 80 to go out through Local Area Network 10.
Thank you for your help. Sorry to be a pain but do you know any software which i could get?
nope.
Get a junky computer, install ubuntu or any other flavor of linux, then install squid (a proxy server).. Lastly google the words..
ssh tunneling putty windows
you can get around most firewalls this way.
Thanks for that....
But i don't want to do that.
Then have fun not getting what you want.

haha that was a funny reply.
Try getting software that redirects your traffic on port 80 through a different LAN connection as stated earlier. This is possible. I currently have 2 browsers, one browser going through a VPN connection and the other using a LAN connection.
And notice how the sofware wasn't named.

Found the name for you. It's Juniper networks, Secure Application Manager. When connected depending on which applications you have configured they will go through the tunnel or not. So when the app is in use, IE can only browse sites through that tunnel, so I install Firefox to browse all other sites.

tethering and utorrent

Hey guys,
Anyone know how to configure port forwarding for torrents when using tethering? I'm on froyo if that matters. I get a nice 200-300kB/sec down and 100/kB up for regular data transmission, but my utorrent is crap.
And no, I will not be abusing my tethering. I just want to have a good working setup.
Thanks
Check your router settings
umm...really? I'm tethering...that means no router. I'd be on 3G.
You can tether to a router/local network... you never specified. You can't forward ports from the phone, it's not connecting to a physical modem you have access to.

I very much doubt your network operator allows the port range required for torrents on the apn you're connecting to... you could try a port check to find out (but they probably drop that traffic too).
Can you set up an SSL torrent on port 80 to test?

[Q] O2 Tethering and Nexus

Hi all, sorry if this has been answered already but i did search and couldn't find anything to this specification.
I have been using my nexus on the o2 network with unlimited data for a while and have tethered for as long as i have had it.
Recently i have had to rely solely on my phones tethering for internet as my home connection is down for upgrades. For some reason i can no longer tether it connects and windows even shows internet access is available but will not connect to any site.
Using cmd and pinging google it just says net connection refused.
Has o2 blocked my tethering? If so has anyone had this before?
Thanks in advance.
Does direct connection from the phone work? Try to browse a few sites on your phone.
If direct connection works and tethering doesn't - try USB tether, if it also doesn't - then you might be right, even though it sounds very unlikely to happen (technically).

can wp8.1 use bluetooth for data?

hi, i just gota lumia 635 to play with and i wondered is there anyway i can have it use bluetooth for its data connection. i have a nexus 5 as my main phone and i can share its mobile data connection via bluetooth easily to my nexus 7. is there anyway i can do the same to share its data connection to the lumia? the lumia seems to be able to share its data connection but i can seem to get it to use bluetooth to use the N5 connection.
please help, im brand new to wp8.1 and have no idea what im doing with it yet.

while i thank you for the input i wanted network data connection, not the transfer of files. ie i want to tether the lumia to a nexus sharing its data connection over bluetooth rather than wifi.
sorry i not realize post wrong link

To use the shared data connection over Bluetooth, the device you're using must support the Bluetooth Personal Area Network User (PANU) role. To find out if your Bluetooth device supports this, check the documentation that came with it or check the manufacturer's website. To learn more about Bluetooth personal area networks (PAN) in general, check out the Microsoft Windows website.
Pair your phone with the Bluetooth device and connect to it over Bluetooth.
In the App list, tap Settings Settings icon > Internet sharing.
Tap Share over, and then tap Bluetooth.
Set Sharing to On Toggle On icon.
again i thank you but im trying to share the connection the other way around. i dont think its possible but hoping ive just missed something.

Setting up chromecast without WiFi

So I'm in the army right now, which means there's a TV but no WiFi available.
I did think of just setting up a Hotspot with another phone but it gets pretty annoying having to have 2 people at all time.
So I went digging in the Internet and found someone at a random forum (can't find it now for credit..), that said that If you set up the Hotspot in your own phone and configure it with another one you don't need the other one around anymore - being the Hotspot works as being connected to it.
Now I'm pretty sure there shouldn't be any reason I couldn't set it up on my own phone (the hotspot), except the Google home app just demands I connect to the WiFi network, which I can't do because you can't connect to yourself sadly.
I think if someone made some changes to the Google home app, or made an alternative set up app it could work. I have no idea how to code an app, so I came here ?
tl:dr I Want an app that does the same as the home app for setting chromecast up, but without checking if I'm connected to a WiFi network. (I think)
I'm guessing that you have no WiFi but you do have a hard line internet connection?
The only issue with what I'm going to suggest is that base rules may prohibit creating a WiFi access point on any of their hardline connections.
But the best solution for you is to buy a Portable Router (see posts here about using CCast in a Hotel).
It's a small box about the size of a DC transformer that plugs into the outlet and also any Network to create a small footprint WiFi access point.
I suggest looking for a model that also has Repeater mode that allows it to connect to another WiFi access point to create your own private network as opposed to a hard line.
It is probably the best way to use a CCast in places where WiFi is not available without having to play with Phone Hotspot which doesn't always work due to the fact the hotspot can't control the CCast in that mode.
The other Option that is most likely to be allowed is to add a WiFi puck to your Mobile account. Then there would be no potential compromising of the Military network (which is why they might not allow the Portable Router to be used) and you would no longer need two phones to run the CCast.
CCast definitely needs Internet so that Puck might be the safest and best way forward for you.
As for what you read...The issue is that if the Phone goes out of range it stops working.

Actually, no Internet at all, just mobile data, but since I got 15 gigs it's OK for me to use it.

To be honest, it is a good idea but my I was mainly wondering if I could solve it via software which is both easier obviously and also I just wanted to know if it's actually possible since I thought of it and I wanna know if I got it right

Not really...All the hacks and such that people try simply don't work well due to the fact that the Phone can't really connect to the same subnet as the Hotspot. When you go into Hotspot mode you can't also connect to that hotspot internally because WiFi is no longer available to the phone.

That's why i suggested tempering with the app so it treats being a Hotspot as if u were with WiFi on connected to one.
Basically take off the check for being connected to WiFi.

The issue isn't the app...It's the fact that the WiFi in your phone can only do one thing at a time....BE an Access Point or CONNECT to an access point.
It can't connect to itself as the radio can't do both things at once.
So when you go into hotspot there is no way to get on the same subnet as the hotspot with the phone.
Because there is no network adapter available to connect to it. It is too busy being an access point.
Basically going into hotspot turns the Phone into a router. A router the phone has no way to connect to. So you either need another device to connect to that phone router or find some other router with internet.
Which is what the Cellular Puck will give you.

Like I said, once the setup is done, being the Hotspot is just like being connected to is. The app still doesn't recognize you're connected but if you're on the web the chromecast icon does pop up when needed, all the third party apps do recognize you as being connected.
All you managed to do with Google Home (which can't be edited by anyone but Google)on the second phone is connect your CCast to the Phone Hotspot for it's Internet. There is no way to avoid that setup....HOWEVER...
As long as you don't set it up to connect to some other Hotspot there is no need to run Home again, Just turn on Hotspot and it should reconnect.
It will even remember the password,

Yea I know, but sometimes friends take it or something and it's a pain in the ass to explain everything, and even when I do it means I gotta reconnect at my end again which is annoying just thought someone could maybe find a solution that sounded really simple for me, guess not, too bad..
Thanks anyway!
Well trying to recode Home is a dead end....Android wouldn't even let you install it!
You guys should just chip in and buy the puck.
It will even let you use Tablets and Laptops as well as simplify the CCast use.
I know this is an older post; not sure if you are still interested. I read all the replies and not sure what to make of it as far as if anyone had a working solution or not. No disrespect to anyone, but I couldn't tell for sure so I'm posting a link to my solution which does work. The two important steps are included. One is using " other wifi" in the drop down list when searching for your hotspot. The second is enabling GUEST MODE.
https://forum.xda-developers.com/android/help/how-to-cast-screen-android-phone-to-t4032653
I’m trying something similar with a Chromecast 3rd gen and iPhone 5S (iOS 12). Main issue seems to be guest mode doesn’t work at all on any apps, and pretty much every solution i’ve seen to this results in guest mode being used for the eventual casting. If you have android or iOS 13 then ymmv.
The only solution i’ve found are workarounds, the obvious being
1) don’t buy a chromecast (it’s not much of a solution but hey it’s $30).
2) use a secondary device to cast.
3) use a tethered travel router, and this can be done with only a phone and mobile data for internet, but there’s a catch:
First i’d Recommend any router by GLi.net (cheapest “mango” router is about $20) as they support iOS and android and both WiFi and usb tethering.
Also, i’ve Tried using a WiFi hotspot on the phone, and it’s the same issue - no connection to the chromecast regardless of how. However... iPhones will allow you to create a hotspot using *only* cables usb tethering, so if you set the router up to *only* accept internet via cables tether (turn off WiFi/repeater tethering), then you can have both the chromecast and iPhone connect to the routers WiFi, whilst providing net access to the router (and WiFi network) from the same iphone’s mobile data via usb. Simple howoto:
Important: Turn OFF WiFi on the phone, and turn off hotspot.
Connect phone to router via usb, accept trust settings.
Turn on personal hotspot, you’ll get a message asking whether to use WiFi or just usb (andbluetooth if it’s also turned on). Select just usb/Bluetooth.
Wait until blue connection bar shows on phone (if not, make sure routers setup properly to gain net via usb tethering).
Now, turn on WiFi on the phone, and connect to routers WiFi.
Setup chromecast as normal, selecting to connect to routers WiFi too.
Note turning hotspot off and on again whilst WiFi is running will start a hotspot on WiFi and disconnect you from router WiFi, so you’ll always have to go through process of turning WiFi off, turn hotspot on, turn WiFi on.
So you can do this with the right router and a usb connection to phone. Or maybe android and working guest mode. Otheriwse, ...fire tv anyone?
