I have an Android phone and a notebook running Windows 7, both are Wi-Fi enabled. Both devices are on the same network and they can't see each other (I can't ping phone from notebook and vice versa). But, to make it more weird, let me show you my network structure.
Name - OS - IPv4 Address ---------------------------------------- Router - - 192.168.1.1 ComputerXP - WinXP - 192.168.1.103 ComputerW7 - Win7 - 192.168.1.104 NotebookW7 - Win7 - 192.168.1.106 Telephone - Android4 - 192.168.1.109
ComputerW7 can ping all devices in given network.
Telephone can both ping
ComputerW7. The only connection that does not work is
Notebook7 <--> Telephone.
I have previously had this problem, I tried restarting
Router, disabling and re-enabling Wi-Fi connection and firewall, pinging anywhere and nothing was working. Later on when my dad came home, I wanted to show him this situation, but suddenly I was able to connect to
NotebookW7 from my
Telephone like magic. I was happy that the issue got fixed. I stopped using this connection for a while and now I wanted to establish it again and guess what, it's again not working. I have no idea what is going on.
I used ping on Windowss and Ping & DNS on Android to test ping.
EDIT 1: For some reason, I was not able to ping
ComputerW7 using my
Telephone for a while. So in my
Telephone I started external software for managing files. I added new network place with IP Address of
ComputerW7 (192.168.1.104) and pressed test connection. It was doing something for a while and then it printed "Test successful". I went back to Ping & DNS, and re-pinged same IP Address and it started working for some reason. I did same thing with my
NotebookW7, but I got "Test not successful" in my file manager.
EDIT 2: Little bit more weirdness. I added one more Android Phone (lets call it just
Phone) to the network and checked all possible pings from outside to the
Phone. Nothing worked. Then I tried to connect to VLC Player at
Phone and it worked. After that I was able to ping
ComputerXP. Not really sure how this works. Only difference is that
Phone has Android 4.2.2, but
Telephone has 4.1.2.
EDIT 3: New thing I tried was to create Wi-Fi Router from
Telephone and connecting to it using
NotebookW7, it worked. However, I still was not able to ping it.
