[APP][Q] Connecting two phones via wifi

Is it possible to connect two phones via WiFi? Does anyone have any idea on how make this happen that can point me in the right direction? I wanna work on this for my senior design project. I basically want to share the sdcard with another phone
Maybe having one phone as a hotspot, and the other connecting to it, or thru an already existent wireless network
Thanks

Anyone? ....

You can probably by creating one phone as access point and connecting the other through ad-hoc connection.
I never did, though had used this type of connectivity on PCs.

Probably you want to make something like that:
frostwire.com/android/
p2p client connects phones via WiFi and shares photo, music, video, documents
they have opened sources but not for Android version.

Sadly you'll need to hack android to allow ad hoc wifi. On another note, Bluetooth 3.0 is kind of what you are talking about but not like a NAS setup which you are wanting. BT 3.0 sets connects/handshakes two devices by bt then turns on wifi for faster speeds. The only devices that I know have BT 3.0 as of now are the Samsung Galaxy S's

Droid Eris: Use as wireless internet bridge

Is there a way to use my Droid Eris as a wireless gateway/router?
The idea is to tether the Eris to a computer with a wired connection via USB and connect devices to the phone so they use the wired (faster) connection speed versus the cellular network.
As an example, someone might be stuck in a hotel that, miraculously, only provides wired internet access, and wants to watch HD movies over the network.
Any help would be greatly appreciated.

You could do that with the computer and bypass the phone altogether, assuming your laptop has wireless and almost all modern ones do.

Thanks for the response, I should have clarified:
The wired computer in question is running Windows XP with no Bluetooth capability and ICS locked down.
I have reserved admin rights (i.e. install, add new network connections) with a few core functions disabled (creating/joining home or office networks).
This may very well be a no-win situation, but I am wondering if the "heavy" lifting (i.e. connection bridging) could be done by the Eris.

tethering using USB

Can the Surface RT USB tether to smartphones? I have an older LG P990. When I tethered to my normal PC it had to first quickly install AndroidNET or whatever. That makes me think that it won't work on the RT.
I need to be able to tether, I could just go the route of a mobile hotspot, but I don't like the idea of every single Chinese person on the train trying to steal my wifi. They are pros at stealing wifi in this country.
I heard you can tether using bluetooth. Is that possible on the Surface RT?
Thanks,
lgnationrc

I tether to Surface from my Galaxy Nexus over bluetooth. It disconnects all the time without any reason but haven't been able to figure out why. With BT I can enable it on phone and it shouldn't eat battery like having wifi hotspot all the time active. I just open the BT PAN from Surface with 2 button presses and it opens in 1 sec. Only if the disconnect issue could be solved...

A few points, for the record:
1: Windows RT *probably* supports USB modems, which is how most wired tethering is done (the phone presents itself to the PC as a USB modem). I haven't tried, though.
2: Unless you use a crappy password - and really, why would you; it's not like you'll need to remember it at any time that you can't access it - WPA2-PSK is effectively unbreakable.
3: Don't be sure that Bluetooth is that much more secure. It is shorter range and lower power, though... but it's also lower bandwidth. A decent cellphone connection (3G, not even terribly good 3G) will saturate it.

Thanks, I will try it and see how it goes. Otherwise I will use Wifi, have no choice. Wifi gets stolen here all the time, even with that kind of setup.
Thank you

[Q] Can we use P920(H) as a modem for a 3G router?

Hello all. I've just purchased a 3G/WAN WI-FI router (TP-Link model TL-MR3420 - link to manufacturer's page). It has an USB port to connect a 3G/4G modem. I tried to connect my P920H (V28b stock ICS - XBSA large partitions) but the router doesn't recognise it. I tried to use an older 3G phone (Sony Ericsson W980) and it works like a charm. In both cases I configured the phones to USB tether with their own configuration options.
Anyone managed to make this work? I believe the router lacks a driver, but I've found no driver for any phone on the manufacturer's page, although I works with the Walkman phone.
Edit: I forgot to mention that all tethering features on my phone works fine. I can turn on my hotspot and I can plug it to a PC's USB port and act like a modem. I just can't do it with my router.
Why I want to do this: Most of you who have nice broadband access may be wondering why I want to use my phone to provide Internet access to my router. Here's why: In the region I live, broadband access is a joke. A miserable 1Mbps insufficcient to watch even the lamest youtube video. But it has no limitations, so it is good for TV upgrades and other connected devices to do their maintenance.
On the other hand, my phone provider has a wonderful coverage around my house, sustaining an average of 3Mbps, reaching 10Mbps late at night. So, when I want a quicker net, like to watch Internet movies or download large files, I used to turn off my router and turn on the phone's hotspot. But even setting its SSID and password identical to the ones on the router, it takes some tweaking on the devices for them to reconnect. It was a nuisance.
With this 3G router, all I would have to do is connect the phone to it and it would switch from WAN to 3G. All I need is a driver that would make it recognize the phone and use it as a modem.

I messed with wifi tethering a bit a while back. Couldn't get it to work. My other phone sees it as a wifi point but won't connect. Something to do with LG not liking tethering I heard. I saw this mod that fixes tethering for some devices but never tried it ( I don't really need tethering). I am curious if it fixes it:

Hello drastic00!
Thank you for your suggestion. I understand that the mod you suggested can have nice effects on slow or even broken tethering.
The problem is that I haven't made myself clear on the first post. I can see it now and I'll edit it right away. The tethering feature on my phone works fine, both WI-FI and USB tethering works. What I need is a USB tethering that makes my router "think" that my phone is actually a 3G USB modem. When I use this feature on a PC, I have to install the drivers. The bad news is that I can't install these drivers on the router.

Okay. I figured if wifi tether isn't working then usb isn't either. So what firmware do you have on which it is working?
There was a small discussion on a thread a month or so ago; it wasn't working for the 4 or so people who posted then...I think we were all on ICS or higher, but not positive. That's when I tried to see if I could get wifi tether to work. I didn't try any usb tethering.
So I guess I am not understanding the advantage of plugging direct to the router. Why not plug the phone to pc (signal in) and the router to pc (signal out)? Because it would be easier to switch from the signal you normally use? This is a new one on me... I have no idea if an ethernet switch would be of use...2 signals in for the router to broadcast and choose which wifi signal on the client end (not sure if your router could do that, just grasping at straws, since I haven't tried anything like this).
It's weird other phones work though, so I am still curious if Crossbreeder mod would do anything. It seems the other phones have a piece of software the O3D does not. Unless the router has drivers installed for those devices by default, which I doubt; you didn't install anything for those to work, they worked out-of-the-box, so to speak, right?

Exactly. Both WIFI and USB tether always worked out of the box for me, with several ROMs, either stock and modded ROMs. Eventualy some modded ROMs did break tether, but usually broke many other things as well Probably too undervolt and/or too overclock among other things I don´t understand.
I remember that discussion about not working tether, but didn´t get involved. It never happened to me. I believe it is more a hardware issue. If it happened to me, the first thing I would do is install the original stock Froyo to be sure if tether didn´t work with the most original firmware.
As to why I want to put my O3D as the Internet provider for my network: I have several devices connected: 3 PCs, 2 Androids, 1 TV and 1 Blu-ray player. The last two are not too easy to make connect to a different WIFI net, even if they have the same SSID and passwords. I used to turn off the router and then turning on the phone´s hotspot. The problem is that almost always several of these devices didn´t realise the switch and kept trying to connect to the unavailable router. The same thing happend when switching from the phone to the router.
Also, I don´t want to buy a 3G modem, because the speed advantage (and low fees) are "connected" to my voice plan. The SIM card is my primary phone number So, I need it to be able to make and receive calls. If I purchase a new SIM card, I would have to cope with two bills. Again, no more advantages.
Breaking news: I just noticed that the Sony Ericsson Walkman phone I am using as a modem only gets 1Mbps download, exactly the speed my provider guarantees. My P920H can get more than 10 Mbps on times, but usually between 3 and 5 Mbps. I believe that V28b stock ICS somehow unlocks some sort of ISP speed limit. Now, more than ever I want to use my phone as a modem on my router.

[Q] WiFi tethering bridge to existing access point

Hi there,
At my girlfriend's house there's an existing WiFi access point for their home network and they also have a bunch of computers wired in with ethernet cable. Mobile reception in the house is terrible but I've found one spot by a window where I can sustain a pretty decent dc-hsdpa link. I'm able to tether my laptop to my phone, the phone creates a new WiFi network ap and my laptop connects to that. That works fine.
The thing is, what I'd really like to do, is to have access to the dc-hsdpa connection from some of the wired computers on her home network. To do that I want to have my phone bridge the house network - via their existing WiFi ap - to the mobile internet connection. I'd like the phone to provide a gateway on the house network that could be manually used from the other computers. (I want to avoid using DHCP or anything as it will disrupt the network for other users.)
I know this is technically possible but I'm struggling to find an application that allows for this functionality. I've spent a good amount of time searching around the internet but to no avail. Does anyone know where I can look or of a suitable application? (My phone is a Samsung Galaxy S4 i9505 flashed to run a rooted variant of the play edition KitKat rom.) I'm happy to pay money.
Cheers, Dave.
