Trying to figure out a Master and Slave cellphone network. - General Questions and Answers

I am trying to figure out a way to slave three cellphones to my current Note 8. I am attempting to do this by having only these four phones in the network and not connected to the internet or a router. The purpose of this is to use my phone to access the cameras on the slave phones. I need about 100m between the master and slaves. The only way I can think of is by using the on-board WiFi radios to establish the network.
Any ideas on how or if this kind of thing can be accomplished?

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

encryption is not compatible RANT

I have all kinds of computers tablets and gadgets. I have had no problems connecting to my wireless network until the Microsoft Surface came along. My router is the Motorola NVG 510. It doesn't have many settings that can be changed. I am using WPA2 Personal AES and a password. The only way I can Connect My Surface to this network is to turn off encryption. l had the same problem with the Surface RT. .
Tried for 24 hours now to connect... AT & T Says the problem is Microsoft related and Microsoft blames AT & T . l GIVE UP!!. Returning the Surface and going to keep my Samsung Slate 7 . . . has Windows8- WiFi and 3G. . .
how the hell do AT&T come into your wireless settings?

Never had an issue with any form of encryption with the Surface RT - it's got the standard windows 8 wifi stack and connects to anything I throw at it, including WPA2/AES.
Not sure why you're having an issue, but you haven't given us much to go on for troubleshooting.
And getting a real router isn't possible?

Apparently this (MOTOROLA NVG510) router is the only one I can use in my area with U-Verse.
Thats bull. Is it a combo router/modem? If so you should still be able to hook up a wireless router off of that if it has at least one ethernet port.
see thats what BT claimed when they installed BT infinity at my grandparents but we dont have the stock router running off of it
Thanks for the suggestions. I returned the Surface. I don't know enough about routers and modems to install anything else or even how to buy something else. On the other hand. Annoys me that every gadget I own (and there are many) connects with no problem EXCEPT the surface.

Your router is old. Something is probably interfering with the Surface Pro's connectivity. Your SP's wifi card isn't busted if it can connect without encryption. It shouldn't have a problem. I'd suggest ditching the modem's wifi and buying a router and using that instead for wifi and leave the modem alone.
99% sure it's a setting in your router that's causing you to not be able to connect a new device through wifi.
First port of call when having wifi issues is to remove all encryption/security settings and have it as a fully open network, if that works then slowly add security/encryption until you find out where it falls over, worse case scenario is a network that appears to be open but uses MAC address filtering to keep people out.

the problem was for sure the modem. There are no settings to tweak... It's gotta be the worst modem on the planet-but then U.verse doesn't feel any faster than my old ATT DSL connection. I asked to have my DSL back and ATT said that was not an option. ATT told me this modern is the only one for my area. Maybe it is time I looked into Brighthouse. I am sure there is a way around that modem but in my frustration I returned the Surface. Very sure I will buy another Surface . . I still have my Samsung Slate 7 with Windows 8... Another plus is it has a 3G connection. the more I use Windows 8 the more I like it, wish the Slate was a bit smaller.
Wireless encryption is done router side rather than modem side. You can use the ISP's modem and the connect it to an aftermarket router without issue. Its impossible for the ISP to prevent that. If its a combo modem and router then it is still possible to do.
All routers must have settings, unless you mean it has limited settings.
I've lucked out personally. My ISP's free router isn't the best on the planet but as a freeby is great. Full range of settings. Its a combo modem/router in one but I haven't had issues with that and it is perfectly happy for me to plug other routers into it (which I did once as an ethernet extension cable of sorts, otherwise my other routers are inferior) or according to a friend who used to be on the same ISP it quite happily connects to other modens and acts as a router perfectly fine still.

We already tried to tell him that and he wouldnt listen.
>We already tried to tell him that and he wouldnt listen.
OP's name is Diane.
Secondly, as posted in the OP, the device is a Motorola NVG 510. A 10-second lookup would show that it's a combined ADSL2+router, and it's not a simple matter of swapping out a router. Combined-function devices are SOP for leased models, since it saves the company money over having two boxes.
http://google.com/search?q=Motorola+NVG+510
It's a Surface problem. The user shouldn't be expected to mess with things like router settings and learn to be a geek. The device in question is obviously in popular use, and it's up to MS to get it right. The OP did the correct thing in returning the Surface.
However, for those with more tech savvy, the above search produces this help page for the modem+router,
http://www.ron-berman.com/2011/11/24/motorola-nvg510-help-page-for-att-u-verse-users/
which has both the manual and more importantly, a FAQ to troubleshoot connection issues, and links to more appropriate forums to ask further questions on this particular topic.
As I said, even on a combo unit you can use a different router. As long as the new router can recieve internet from any other device via ethernet all you do is connect it to the ISPs router. It will then share that connection. Yes your ISP's router will still be broadcasting but so will the new 3rd party one, you just connect to that. This is a configuration I have tested with a BT homehub and some ****ty Netgear.
To access the new routers settings, unplug it from the ISPs router first and then access the settings in the normal way. or if you can find the new local IP for the additional router you can use that.
>As I said, even on a combo unit you can use a different router. As long as the new router can recieve internet from any other device via ethernet all you do is connect it to the ISPs router. It will then share that connection.
Either the new router has to be reconfig'ed into an AP, or the old router needs to be disabled. Can't have both routers active. Likewise, the old wifi needs to be disabled, or the new one reconfigured that they don't conflict. Regardless, it's not plug and play. Either or both units would need configuration.
The household Internet router is the single most critical piece of equipment there is, because if the user messes up, s/he loses Internet access ENTIRELY and access to any further help. Without local help, that may mean several days' downtime and an expensive bill for onsite repair. I would NEVER, EVER tell a non-tech user to reconfigure his/her router, especially when the person said "I don't know enough about routers and modems to install anything else or even how to buy something else."
Everyone here has good intentions and want to help. Then, the first thing to helping is to listen to what is said, and gauge the person's comfort level with tech. No one even bothered to check up on the OP's router model.
The OP has a stable, working setup. Anything that jeopardizes that setup is bad advice, not unless you are willing to foot the onsite service cost for the person. The preferred solution is to remove the known-problem component, which in this case is the Surface.
PS: A long shot is to go into the Surface's Device Manager, select the Properties tab of the wifi card, and muck around with the advanced settings (if there are any).
You can totally daisy-chain routers using their default settings. Not sure why you would think otherwise...
That said, if you wanted port forwarding and such to work smoothly, it *would* be best to turn off DHCP and NAT on the inner router. However, that's not necessary to simply get Internet access via the router.

Which is precisely what I originally said.
I have daisy chained a cheap as **** netgear router to my BT homehub without any setting changes at all. I was actually using it as an ethernet extension cable pretty much, I didnt have a single cable long enough so I plugged one between the homehub/main router and the netgear and one between the netgear and a raspberry pi. Would you look at that, my laptop can connect to the netgear and get internet access from it, the pi also connects via its ethernet port perfectly.
My grandparents use a set of homeplugs, how do they connect? daisy chaining.
One of my mates has 3 ethernet devices in one room but only one LAN port drilled into the wall (he had an electrician out once to actually have LAN sockets fitted in a few rooms). Solution: cheap wireless router connected to the LAN port in the wall. Other devices connected to the router. Router had 6 ports so he still has 2 left over. Devices connect to it fine. Originally it was default settings but he has since gone and disabled the routers wifi as he doesnt use it.
That said. I came across a linksys unit once which refused to be used as an access point of any kind. But that was only once.
>You can totally daisy-chain routers using their default settings. Not sure why you would think otherwise...
Having nested routers (ie segmenting the network) is a prescription for myriad network problems in the hands of a non-tech user. Again, listen to what the OP said, rather than assume everyone is a geek who knows what DHCP and NAT means, let alone how to change them.
Even if the OP can get the new router configured and running properly, the potential for problem remains. When ISP service goes down, the ISP tech will remote troubleshoot the leased equipment (the old router), since that's the ISP's responsibility. With user equipment attached, troubleshooting responsibility passes on to the user, which the OP has stated in no uncertain terms that she's not capable of.
The point isn't to get Internet access. The OP already has Internet access. The point is to get the Surface to connect to the network, but NOT AT THE EXPENSE of adding networking complications that the OP can't handle.
>I have daisy chained...
This suffices for simple Internet access, until you run into programs or devices that break because of the multiple redirections. I doubt UPNP/DLNA works on nested NATs. Ditto discovery. Devices/periphs on one network segment won't be able to connect to those on another segment.
The wifi will work, but given that most 2.4GHz wifi default to channel 1 or 6, it will likely conflict with the old wifi and work POORLY when both are active.

[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.

[Q] Long-range Wifi repeater with auto hotspot authentication?

Hi All,
At this point, I'm just brainstorming, and would like some input. (I hope this thread is in the right place)
I'm trying to find a setup to connect to free wifi hotspots that are far away, and share that connection to a group of devices locally. For example, this solution may be useful in a boat or an RV, when you're not particularly close to a free access point.
There are commercial solutions like the Rogue Wave however, this doesn't do anything to authenticate through the Terms of Service (TOS) pages that are frequently used at free access points.
This is what brings me to using Android. There are Android apps which automate the process of accepting the terms of service. My favorite right now is WebWifiLogin (I'm familiar with the security risks involved in using public wifi; and may also have the Android device to also establish a VPN connection when doing this.) (I can't find an equivalent macro-authentication solution that will run on a PC, which would make this much easier.)
So here's my proposed solution:
1. Start with a powerful omnidirectional wifi antenna (Possibly add an in-line amp if needed. Also perhaps a directional antenna may be better for non-mobile use.)
2. Connect the antenna to any Android device that supports an external Wifi antenna. I found several Android TV devices which should work. Like This, or possibly this.
3. Set up some kind of local access point/bridge. One option may be to use fqrouter2 which supposedly uses the same Wifi radio for the local WLAN, while it also connects to the remote one. Another option may be to USB or Ethernet tether to a DD-WRT Router.
Result:
The Android device has a range to connect to a free hotspot up to a mile or two away, then automatically accepts the TOS using the WebWifiLogin app, and shares that connection locally to a handful of devices.
So am I crazy? Is this too complex to work correctly? Is there a simpler solution that I'm missing?
Can anyone confirm whether I've posted this in the correct sub-forum?
Thanks.
I use a slightly different method which yields the same results.
I have a Linksys WRT54GL router (with high gain antennas) which runs DD-WRT and a script called AutoAP. The script scans for unencrypted WIFI access points, makes sure they're live, and automatically connects to the strongest one in range.
I set up a second WPA2 encrypted WIFI SSID in the router which I connect to with my Android tablet. Once WebWifiLogin on the tablet handles the TOS login, the remote access point allows web access for any device that connects to the WRT54GL router (either by WIFI to the secondary SSID or through one of the ports)! This happens because the remote access point usually checks/remembers TOS acceptance by the MAC address of the connected device. Since it only sees the MAC address of my router, anything behind the router now gets access.

This is great information; thanks!
I would not have thought WebWifiLogin would work when connecting through another router. When WebWifiLogin is running, its status says "Listening for WiFi events" (Or something similar) so I was under the impression that WebWifiLogin would only work if the connection to the AP is made directly by the Android WiFi interface, and not through a intermediary router.
This makes things much easier.

[GUIDE][NO ROOT] How to use tethering for home network

Hello everyone! Here's a nice little guide on how to tether your phone and use that ability to power a home internet network. I have done tons of trial and error to get this working with bits and pieces from numerous forums and google research. This has been working flawlessly for me and it's a "set it and forget it solution".
The reason why I wanted to do this is because I live in a rural area with no high speed ISP. My only option was to use a data capped satellite ISP that is extremely limited in ability and expensive. Without further ado my guide to achieve an unlimited, data cap free, tethered home network.
What you need:
Android phone you're willing to dedicate for full time use
Computer with windows and LAN port you're willing to dedicate for full time use
Wireless Router
A nice USB cord for your phone
A nice CAT cable
1) First thing to do is look around for an unlimited data (4glte preferred, no tethering plan needed) cellular plan. I know there are a few out there but I decided on MetroPCS due to the coverage I get and the price ($60 a month, no contract). I opted for just a sim card as I had an android phone laying around.
2) Make sure your android is unlocked if it's not on the same network you are trying to use. My phone was tied to AT&T and I had to call them to unlock it. Most carrier will do this if the phone in good standing. Meaning paid off. Or root it.
3) We will need to find out where your equipment will sit to receive the best speeds. I recommend putting your phone in "field test mode" and walk around the house. The lower number the better. I also ran a speed test in certain locations to give me a rough idea of what speeds I would be getting. If you are really serious about this set up there is equipment out there to boost cell signal in your house. I like WeBoost.
4) Download your tethering application. I have tried multiple apps but only one worked perfectly but with different hardware you might have other results. Clockworkmod Tether ($4.99) and PDAnet+ ($7.95) worked alright but I had issues with it talking to my router and clients so disconnects where frequent and frustrating. I ultimately went for EasyTether ($9.99) and it has been working fantastic. Mind you when using Clockwork and PDAnet I would be getting a DL speed of 6Mbs when my phone was 13Mbs. I don't know what would cause that but with EasyTether I am getting speeds very similar to my phone with no speed loss.
5) All three tethering applications require you to install a sister program on your computer to work. So install that on your "slave" machine. They are all about the same process, install an .exe and drivers for your phone.
6) Test that everything is working. The tethering application will have instructions on how to USB tether your phone. We need to check that it will give your slave machine an internet connection. Simply open a web browser and see if it is working.
7) Great! Now your are connected and able to surf the web! But wouldn't it be great if you could use this on all your devices? This is where the router comes in play.
8) Now I don't know what router you are using but mine is an ASUS RT-N56U and the principle should be the same. Plug your router into power and reset it with the button on the back (10 seconds). Unplug from power. Connect the CAT cable to the WAN port of the router (the one that usually connects a modem to the router) and the other end to the LAN port of your slave machine. Plug power to the router and allow it to boot up. Now on your slave machine go to Network and Sharing Center, View status on the tether connection, properties, sharing, check Allow other network users to connect through this computer's Internet connection, select the Home networking connection as the router. With everything done correctly you should be getting an internet connection to the router.
9) Now this is all fine and dandy but there are some settings in the router you can configure to make it more reliable. Our cases could be different but this is what has worked for me. I'm no networking genius by any means so my setting could not mean anything. In my experience things would work for a few mins but streaming to chromecast or connecting a mac to wireless mysteriously cut all connection. So here are my settings.
Disable MAC Filter
Disable Wireless Scheduler
Enable IGMP Snooping
Enable DHCP Server
Disable DHCP Routes
Disable Multicast routing (IGMP Proxy)
WAN Connection Type-Automatic IP
Enable UPnP
Connect to DNS Server automatically-NO
DNS Server1 8.8.8.8
DNS Server2 8.8.4.4
Everything else is default
I don't know about the NAT for all you gamers out there but I am sure there is some router configuration you can do. If anyone has ideas on how to achieve this please chime in.
10) Congratulations! You have now set up a home network with your phone and can use it like any other ISP. If you experience any issue with this process let me know and I will get back to you with an answer. I have had to do a lot of trouble shooting to get to this point.
