Fake Base Station? - LG V20 Questions & Answers

Hey guys so I'm trying to find my global IP address and no matter what app I use and going to About Phone I'm always down a local IP 10.xxx.xxx.xxx. Also when using Net Guard firewall, and not connected to wifi, I have to allow access to the wifi connection and not the cellular data connection in order for an app to gain access to the internet. Is this what hastens with a fake base station and is my phone hacked??

[Q] Is it possible to renew IP address over GPRS/3G?

I'm using a Nexus One (Android) on Vodafone in Australia and would like to know if it's possible to release/renew an IP address over GPRS/3G.
I've tried using netcfg, ifconfig but none of them seem to actually get another IP. If I shutdown data and start it again, I get another IP.
Any ideas?

Did you try turning airplane mode on and off? That may cause you to get a new IP.
In GPRS your IP is decided by something called a "PDP Context" (a sort of "contract" you have with the Network that decides which data service you can access, what would be the speed of your connection (QoS) and your IP address).
This PDP Context is not easily killed and that's the beauty of the thing : when you're in bad coverage or moving from cell to cell, this PDP permits you to keep your data connection (it'll be probably slower but your web page will go on loading when you'll get coverage again etc...)
So in a word, to renew your IP you must recreate your PDP Context and in order to do that your must reconnect to the network : airplane mode, turn your device off/on or cut data then turning it on like you've just said. No other way...
I'm not an linux expert but I think the "renew" command send an order to the network card. In your phone there's not really a network card but these network protocols, so that's why it doesn't work for me...
I'll search but I think will be the same with 3G Networks...

[Q] Ip received via Tethering

Hi, one of my coleagues has a wildfire. Unfortunately, when he connects his phone to his pc in thethering mode, the network connection that is created gets an ip address which is 192.168.100.x. This poses no problem when surfing, but, when he connects to work LAN via VPN, the ip blocks clash, as the LAN at work is also 192.168.100.x block. Am i missing the setting where this can be changed on the phone, or is it impossible?

Can't get WiFi internet working

Phone is connecting and receiving an IP and strong signal no problem, but can't get any type of internet to connect (imo/opera/market/facebook app etc...) there's no proxy or password... Notebook and other computers are using the network fine.
Any suggestions?
nm.. got it.. had to set DNS in wifi -> advanced.
you can ask for help to the sellers.
Check on the router, whether your phone is correctly connected. Try to download from the market some wifi software, that gives more information about connection - i. e. Wifi Manager.
Do you use official firmware or a custom one?
The DNS information should have been provided as part of the DHCP request.
Any firewalls?
Does the phone work on other wifi networks?

[Q] Wifi issue. New findings?

Hello, been a long time reader from my G1 to my G2 and now my nexus 4.
I am unfortunately not able to use my device on certain wifi networks which is a real bummer.
Being that i have a background in diagnosing computer problems in my real world life, i thought i would post my findings as i found some interesting things!
First i will say that the network i will use as the demonstration is secured with WPA2 PSK AES security and encryption.
I can connect to it and often find i have problems on the first connect to the network. By this i mean if i have made my wifi settings 'forget the network' and then try to connect again.
On the first time it seems to indefinitely hang, showing the message 'authenticating' on screen next to the network and if i long press on the network name and press modify, the dialog shows that i have a link speed of 1mbps.
I can usually get past this by turning wifi off and on and then reconnecting, at which point it will connect straight away and have a normal link speed. (in this example 72mbps).
After i am connected, i find that the following does not load:
-browsing webpages through chrome does not load
-the wifi icon turns grey
-play store cannot load anything
I find that i get assigned an ip address by dhcp correctly too with the right gateway and dns.
I decided to download a network tool to have a better look. I use fing personally.
I found it very interesting what i found, which no other threads about wifi issues mention.
Network discovery found every device on the local wifi network.
I was able to scan the services of my computer which is also on the network and it found everything, including a http server which i run which i could browse to.
In fact i could do everything through wifi with this device and most others.
Again it got interesting when I then took a look at my gateway, the router.
I had discovered its mac address which i can verify through my computer is correct which to my understanding, being that i can communicate through the wifi, means that i have the information available to send information to that physical device?
When trying to scan services, i find nothing, which is not true, at the very least it exposes a http server on port 80 which my computer can access.
When trying to ping i have 100% packet loss.
So at this point it is only the gateway i cannot access.
So i figure i could setup another computer which is connected to the network with a wire to share its connection through wifi onto that network and then i have a standin gateway?
I connected this computer through wifi to the network and pinged it succesfully with my phone. I then turn ICS on my wired adaptor to share to my wifi adaptor. I ensure that the wifi maintains an ip address in the right range and subnet.
I then try to ping that ip with the phone and it then gets 100% packet loss.
Could this be that when a device is configured to act as a gateway something changes about how it handles any packets sent to it that the nexus 4 is currently in compatible with?

I have found a bit of a workaround that i can use!
When i said i turned on the wifi and ICS i did the following:
-Turned on wifi.
-Connected to wifi network.
-Turned on ICS on my wired network to share to my wifi
-Observed that my ip changed from 192.168.10.x to 192.168.137.1 with no gateway or dns.
-I decided to change my ip on the wireless to 192.168.10.x and gateway to my router 192.168.10.10
-I then tested.
I ran through this again but slightly different:
-Turned on wifi.
-Connected to wifi network.
-Turned on ICS on my wired network to share to my wifi
-Observed that my ip changed from 192.168.10.x to 192.168.137.1 with no gateway or dns.
-I decided to change my ip on the phone to 192.168.137.5 with gateway and dns as 192.168.137.1
-I then tested. And it works!
I know this doesnt fix the wifi issue itself, but for me, this makes a big difference as i can now use wifi at work where we also have poor mobile network coverage.
Edit:
Additionally i previously tried to setup this same computer to host a wifi network to share the connection using 'netsh' and creating a 'hostednetwork' but i found i was in the same situation where i still couldnt get the internet.

WIFI & Mobile Data Simultaneously?

Hi, New poster so if I've posted in the wrong area please don't bite
I've been connecting my phone to a smart device (miracast-ing 'direct') but as of late the connection has become unstable and generally unusable. I had the brainstorm of using an old router to stabilize the connection, this seems to have done the trick but now I'm unable to access the mobile data as WIFI has assumed priority. Please bear in mind I don't have home internet so the router is being used solely as a go between for phone and smart device. Is there any possibility of WiFi connection whilst have access to mobile data or is this just a pipedream?
Thanks in advance
You can just start a wifi network from your phone, connect the smart devices to your phones wifi and use mobile data normal as internet connection (this is standard if you start a wifi network from phone). You wouldnt even need the router with this szenario, if the wifi signal of your phone isnt strong enough you can connect your router to the phone and extend the wifi with the router.

Thanks for the reply
But creating a mobile hotspot won't help because it doesn't solve the faulty (actually non-existent) miracast connection, plus I don't need a hotspot because only the phone needs internet access. My earlier explanation was probably a bit vague.
My goal is to mirror my phone's screen but to also have internet access solely on my phone.
Phone➡Smart Device➡Display - Can't connect (used to work faultless).
Phone➡Router➡Smart Device➡Display - Connects but no mobile data available because the phone thinks the router has internet access covered.

Creating a hotspot is not for giving the other devices in your network internet access, this is the only way you can use the wifi on your phone with using mobile data at the same time. I dont know why but android devices never use mobile data when they are connected to a wifi network and there is no internet access available. So if you configure your router as a wifi repeater and setup the phone as base station, your wifi signal from phone to router should be good and you can connect your other devices to the router, the phone should see all devices in the same network if you stop the dhcp server in your router and only use the one from your phones hotspot. Should look like this :
Phone (with DHCP) <----Router---->Smart Device---> Display

Cheers will try it out.
Hopefully that sort of config is available on my router as it is loaded with a custom firmware from my old ISP provider.
Thanks

Router ISP custom firmware seems restrictive (no advanced wireless settings) plus WDS is not officially supported.
Possibly achievable but beyond my technical savvy
Thanks for the advice anyways.

Do not use WiFi 5Gz , use only 2,4Gz, and wifi 5Gz off for router and smartphone
