There are a few different methods you can use to troubleshoot this.
1) Router Setup
The simplest way to solve this issue is to open up your router config. Based on your model and brand, you can check their help sections on how to do this.
On most home networks, this will be 192.168.1.1 which is also known as your gateway. If you have a doubt, you can check in your windows network settings.
You can open up your browser of choice and type in this gateway IP address and it will give you a login page. Again, check your specific brand of router and use the default login details.
Most modern routers have a DHCP list where you can check all the devices connected to your system. If your Pi is successfully connected to the network, it will more likely than not show up here. If you share your router brand and model, we can give you more specific help on where exactly to look.
2) Direct Connect
If you have a display, keyboard and a mouse available, you can try booting the pi up with these connected. Once you are in, open up a terminal and type the following command:
You should get a response like this:
Link encap:Ethernet HWaddr xx:xx:xx:xx:xx:xx
**inet addr:192.168.1.xx** Bcast:192.168.1.xx Mask:255.255.255.0
inet6 addr: xxxx::xxxx:xx:x:xxx/xx Scope:Link
UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1
RX packets:2895365 errors:0 dropped:6 overruns:0 frame:0
TX packets:6180589 errors:0 dropped:0 overruns:0 carrier:0
RX bytes:136456331 (130.1 MiB) TX bytes:263301601 (251.1 MiB)
Note the second line following the inet addr: field. This would be the IPV4 address that your Pi has assigned based on DHCP.
You can also type the command hostname in your terminal and find your hostname
If your IP address does not show up here, you need to configure your network correctly in the /etc/network/interfaces file which is beyond the scope of this question.
If you can post the details of your test with these two methods, we can help you more.
