[Q] 3G/4G + Wifi At The Same Time - Samsung Galaxy Nexus

I know how to do this in Windows and Linux, but not really sure how to go about it on Android...4.0.4 to be exact.
What I'm trying to accomplish is to have both active, with the 3G/4G handling internet-based activities and the Wifi handling local network access.
Why? Basically my home internet is horrible however I have some services/shares on my LAN that I want to access on my phone. And I can't switch between them, not an option. Because many times I'm wanting to take a picture from my file server (Accessed over Wifi) and then upload it to Flickr (Accessed over 3G/4G).
In Windows it's setting the gateway metric, and I would set the connection with the internet with the lower metric while the LAN-only connection gets a higher one.

I'm not aware of any way to do this on any Android - I would imagine it requires a heavily modded ROM.
You could of course tether a Windows or Linux computer on your network to the Android and implement gateway metrics from that end, in order to copy photos from the LAN server to the Internet via cellular.

Ask Cyanogen, if he could do such a thing, afterall, he has been hacking/modding Android since it's inital release. If anyone can help you, it's him... Sorry dude.

While I've never tried it, you might want to try setting up a DHCP reservation on your LAN that DOES NOT provide a gateway. This should allow Internet access using your egress connection while still allowing local LAN access-at least this is how it works for most computers that are multihomed.

[REQ] How To - Remote Desktop Mobile

Is there some tutorial/help on using hte Remote Desktop Mobile to connect to a PC? I haven't been able to connect TP 2 to my PC running Vista. I put in the Computer name, User name, password, and domain and when I clicked "Connect", it returned an error:
Cannot connect. Likely reasons are:
1. specified computer name or ip does not exist.
2. A network error occured while establishing connection.
I tried both domain name and ip. Made no difference.
I also tried both on 3G as well as WiFi but it made no difference.
You'll need to set up two things:
set the vista machine to accept the remote connections
http://howtogeek.com/howto/windows-vista/turn-on-remote-desktop-in-windows-vista/
forward port 3389 on your router if you have one
http://portforward.com/
Then you should be up and running!

Thanks, mad-tunes. Got it working now, at least when connected by WiFi. And when the phone and the PC are on the same Wifi network, I can connect simply by putting in the computer ip address. No domain is required and no port configuring required too.

Good stuff, glad it helped a bit....
If you can't connect from the outside world (ie, using GPRS), then it's most probably a port forward thing...
If you want to get this bit working: How's the machine you're trying to RDP to connected to the 'net exactly?
(ADSL modem, router etc?)

Yes, the PC is behind the router. So probably woould need to do port forward as you have suggested. Having tested it yet. Would try this out later this week.
I was wondering, is theres a way to do this if youre on a home edition of windows?
the home edition I dont believe has remote desktop.
Remote desktop mobile using 3G connection
Has anyone gotten remote desktop mobile to work using only a 3G connection? I've got it working perfectly using wifi but can't for the life of me figure out how to do it over 3G. I searched and the closest thing I could find to being helpful was the following:
I had the same problem till I created two VPN connections. One for internal use (WiFi) and one for extenal use (3G).
The internal one uses the internal IP address of the VPN server and the external one uses the external IP address.
You have to sleect which connection you want to use before starting the connection depending on whether u r using WiFi or 3G.
Hope that makes sense. It works 4 me.

This makes sense but it's confusing about what to change in the VPN connection settings. Can anyone explain in more detail?
Thank you very much

No. You can only use third party solutions like VNC. RDP host is not included in Home Edition.
You have to go into your router and set up a port forward so that 3389 goes to internal IP address of the system you want to remote into. If you have port forwarding/triggering, you can have a different port (eg, 3390) trigger to 3389 internally. If you don't have port forwarding, you can change the listening port from the default 3389 to, eg, 3390 and then you can create a port forward to remote in that way. To access, add :3390 to the end of the remote address (eg, 64.246.222.91:3390). The registry path to the listening port is:
HLKM\SYSTEM\CurrentControlSet\Control\Terminal Server\WinStations\RDP-Tcp\PortNumber
You must reboot after changing the setting.
If you have a domain, it is incredibly useful to set up DNS for this, then you can simply enter the DNS name in the client. This works internally as well.
Update: So i just went to a Starbucks and tried using the wifi there to connect to my remote desktop and it couldn't connect!? But it can connect when I'm using the same wifi router as my remote computer does this mean I don't have the router properly port forwarded? Or is it some other issue? Any advice would be great.
Thanks
When you use your wifi at home, it ends up in the same IP subnet as the remote computer, so all you need to do is to enter the computer name.
When you're at a hotspot, you need to enter the public IP address for your router and step up port forwarding. Wifi outside of your home is no different from using EVDO as far as IP addressing is concerned. You must enter via public IP.
If you don't know what your public IP address is, open a browser from any computer at home and go to this URL:
http://whatismyip.com
It will tell you what the public IP is.
Cheap Loop-Hole
I got Remote Desktop to work on 3G.
First open Opera (or what ever your default browser is) set a home page to something that takes at least 5-10 second to load (if longer, even better), like an email account or m.myspace.com. Simple sites like m.google.com won't work because they load to quickly.
Close OPERA: I mean make sure its closed not just minimized.
This next part needs to be done rather quickly, so I advise making Remote Desktop a top icon in your Start Menu.
So Launch opera, and quickly launch Remote Desktop and hit connect.
Remote Desktop will piggy back off the Opera browser connection to get out to your computer.
Note: (make sure remote desktop works at home first, either by wifi, blue tooth, or direct usb, and by checking it from a computer outside of your network) once you know it works you should be able to connect to it.
Also note: as some one stated above, make sure that proper ports have been open on the computer and router than you should be good to go.
I'm sure their is a registry fix to get the remote desktop working without doing this, but this is the only way I've been able to do it for now..
Hope this helps...

I'm currently using AT&T Tilt 2 Stock Rom and Radio.
Check this out guys, it might be of some help: http://forum.xda-developers.com/showthread.php?t=533664
Thanks a lot guys! It's working just fine now (on both wifi and 3G!) turns out I didn't have the router properly port forwarded.
just started trying to figure this out today. spent about 15 minutes but couldnt get it going.
just installed windows7 on my old pc and im trying to get my htc tp2 (rhodium) to work with the preinstalled Remote Desktop Mobile application. i forwarded port 3389 on both tcp and udp since i didnt know which was necessary.
is a static ip necessary to get this setup by going into the ipv4 settings? also, what is the application looking for with the input for "domain"? - subnet mask? default gateway for my home network?
so far i have tried the following inputs in my tp2 for Remote Desktop Moble:
Computer: public ip
User Name: windows7 login name
password: windows 7 login password
domain: ???
any help is appreciated. going to try this more when i get home from work.

network-wise what you need to do depends on how your PC's connected to the 'net...
if it's connected directly via something like a USB ADSL model or Virgin media cable box, then you'll only need to let 3389 through your PCs firewall.
If it's connected via anything like a router, then you'll also have to allow 3389 through your routers firewall, as well as forwarding port 3389 to your machine inside your network.
it's the port forwarding which needs the internal IP of your PC, so a static one's a good idea (otherwise, if your PCs internal IP address changes it'll stop working). you could set your router to always hand the same IP to your PC MAC address, which can be the best of both worlds (and how I do it).
http://www.portforward.coms a good place to start to find how to forward ports for your router if you're using one..
You also have to go to control panel>system>advanced system settings>remote and set things as you need in the 'remote desktop' section.
if you don't have the 'remote desktop' section, then you're running one of the home versions of the OS which doesn't support Remote desktop conenctions (out of the box )
re domains...if its a normal home PC and nothing to do with a business, then you wont have to enter one at all.
Once you're at home, get your TP2 on your internal network (wifi), and then try to rdp to your machine using its INTERNAL ip (192.168.*.*) and see if that works.
if it does, the PC end's fine and it's your router config you need to get right. if it doesnt, then its something at the PC..
post back here if you still have trouble..
ok, so connecting with the tp2 via 192.xxx.x.x works fine from within the network at home on wifi.
however, once i try and connect with the public ip, it doesnt work. did the port forwarding thing.
i setup the static ip, i tried putting the host pc in the dmz, and still nothing. i tried disabling the host pc's firewall, and nothing.
in remote desktop mobile, im putting in the public ip of the host pc, and have tried filling in the username and password fields, and also tried leaving them blank.
any ideas?

if its workin from inside your network, your PCs set just fine...so it must be the firewall or port forward on your router...
double-check that 3389s alowed through its firewall
and
the forwards set to point UPD+TCP on port 3389 to the current internal IP of your PC.
tbh, I cant think of much else but let me know how you get on
ah, got it working. had to forward from ANY -> 3389, not 3389->3389. duh. works now.
thanks guys
Strange, you shouldn't have had to. RDP defaults to 3389 so the client should be using that from the word go (I know mine do!)...it could be a wierd router thing.
Depending on the exact option(s) you had to change to get it going though, it's making your machine a little more open to the outside world. but maybe not in a huge way....
(so, is it now AnyIP:AnyPort>YourIP:3389 or AnyIp:AnyPort>YourIP:AnyPort? I think forwarding all ports to 3389 would wreck eMule!)
It's probably worth changing the port used from the default though tbh.
Your change it in the PCs registry and add ortno to the end of what you enter into the client.
(so it'd be something like 192.168.0.1:3390, for example)
Then change the rules on the router to match, of course.

[Q] Portable Wi-Fi hotspot

Hello,
I want to use portable Wi-Fi hotspot on my phone to connect to my laptop in places where public wi-fi is not available, or to connect to two computers to each other. And it seems to be working.
But I have a problem. I do not want to use mobile network to access Internet for those computers. I want only to exchange data between phone and computer, or between computers themselves.
But every time I switch on hotspot, 3G connection switches on automatically, even if it is switched off on purpose. I know this is intended use of hotspot, but I have a question:
Is there a way to prevent phone switching 3G network on in wi-fi hotspot mode, or just preventing data traffic over 3G?
Or I am missing the point completely?
The application is not intended for such usage; all it does is route traffic between connected wlan-clients and the carrier's apn. The phone itself has the ip-address 192.168.1.1 during this setup, but it is not listening on any ports that would be useful for your setup (ie 'cifs/samba').

I do not know if I do understand you but here are the facts:
I connect two dell laptops to portable wi-fi hotspot on my wildfire s:
one is : 192.168.1.135
other : 192.168.1.185
I can ping one from another. If I share a folder in one (.135) and go to others(.185) "Search for computers or people" I see all files in shared folder and can do all the usual operations over them (edit, move...)
Also if I install Remote Web Desktop from Market on my phone I can access phone through web interface.
In a word, I can do all things as on "normal" wi-fi network ( and I promise it is the only network around here ) except all the time I have 3G switched on. And I do not want to do that because I see my network data traffic going up.
So, as I see things, my only problem is unwanted 3G traffic.
Help?
Ah, but you did not mention that you had installed a seperate application to open up a port for the webinterface.
This however does not change the intended usage for the mobile wifi hotspot application!
hey...you can try this:
1. go to your mobile network settings
2. create a new APN, a dummy one
3. set the new APN as default
4. launch your wifihotspot
I did not test it with 2 pcs but, when u launch wifihotspot, 3g no longer comes on and my pc still connected to the wireless network without any problems.
Let us know your results
Cheers,
Hey,
I ran more test on this issue. The previous posted solution works like a charm.
I was able to use the wifihotspot as a wireless access point:
1. 2 or more PCs can communicate with each other (browse folders)
2. If one of the PCs has internet access, it shares to the rest of the PCs
3. If one of the PCs has an ethernet connection to a server, all other PCs also get connection to the server
For 3. to work, you will need to brigde the local area connection with the wireless connection on the PC that has cabled ethernet connection. Also browsing folders will work only if you use \\server ip (\\servername does not work).
I will try getting DNS access via the hotspot later.
Hope this helps

[Q] evo hotspot tethering and dd-wrt client bridge

This has been posted before, but I have found no solution in the thread.
As a network backup if/when internet fails me, I need to use the evo 4g to serve as the host for my client bridge (netgear with dd-wrt).
I've been using the client bridge successfully to connect to my Linksys router across the apartment.
I have to have a hard wired connection for my voip phone I use for work.
I match all the encryption, channel, ssid, etc. as I do for my normal network, but when I try to change everything over to match the cmod hotspot (not the wireless tether app which I have nothing but trouble with), it never works. All wired connections get a 169 IP from the router.
Google says that it needs to be in infrastructure mode, and it appears cmod7 uses that. I've tried a vast amount of different ssids, encryption methods, rebooting, etc.
Any info would be greatly appreciated. Does a different rom work better for this method, or do I need a different wifi app besides the one embedded in cmod7?

I don't think the router is giving you 169 IP addresses, those are a default random IP address that the Windows TCP/IP is assigning itself by default, that was useful back in the workgroup and hub days before the internet. I am researching this for future use, and will check back.

[Q] Port Forwarder Ultimate for Newbies

Dear All,
Anyone managed to use "Port Forwarder Ultimate" app from Playstore? https://play.google.com/store/apps/details?id=com.icecoldapps.portforwarderultimatepro&hl=en
I'm not a technical person but this method has other potentials to explore. Maybe someone has patient to teach non-IT person.
I know that I should be satisfied with "USB tethering" in android. But users experience improves with new things.
As prerequisite, we should be able to ping our phone's public IP. but how to ping mobile Public IP?
A detailed guide with screenshot or video will help.
Thanks,
AB
This app does not provide such a feature, it would work if it was installed on your carrier router.
You have an class c address witch is not routable.
The app provide means for running a server app on your phone that is using a port below 1024 , ex: ftp, web etc. If you are connected on your wifi network and make proper port forwarding on your router than you will be able to access your phone from the Internet. But it does not make any sense in doing so.
To access your phone's external ip address regularly you need to run the DynDNS client that forwards your ip to dyndns. When you setup an account with DynDNS you select a url to use and DYDNS will forward any requests to that URL to your phone's current ip address. Naturally you will need a service running on your phone like a web server, ftp or vnc depending on what you want to do.

Connect to WPA2-Enterprise wifi

Is there any way for the fire TV to connect to it? My university uses it, and I was wondering if I could connect, but the access point is not showing up
Can´t look now because I´m not at home but wasn´t there a setting for a manual AP setup where you could enter the SSID by yourself?
Some organizations may keep a second network available for legacy devices like printers, XBoxes, and older machines. You can check with your university's tech support to see how you can add your device to the list of allowed access for that network.
This isn't a guarantee that this network exists for you, but most enterprise and even some residential-grade equipment have this capability.
Otherwise, you might be able to find a router or range extender that can understand and connect to WPA2-Enterprise to work around this. In a pinch, an old laptop with two wifi cards or a wifi Ethernet port should suffice.
Or you may want to scrap wifi and run an Ethernet cable to your dorm's jack or personal switch.

Thanks the responses, but neither of them works well for me. there is a secondary unsecured wifi network, but it is just too slow to use, especially for streaming videos. I sideloaded a wifi APK onto it, and the networks DO show up, but there is no way to enter the login information (you need both a username and password.) Anyone know of an app that can do that?
