You have a networking issue somewhere, and have admitted you don't understand the software you installed on your router or how to use it... There are so many potential issues with your network setup that could cause this, not to mention possible issues with your integration, or drivers/apps you've installed, that without a LOT more detailed information the best anyone is going to be able to tell you is the following.
Ensure all your devices are on the same LAN subnet, Ensure no traffic is blocked between your devices, ensure your router is allowing DNS, ensure that your network protocol and security are the proper type for your devices, many don't like the 2.4N spectrum, others don't like specific types of security implementation. TKIP/AES/ETC... Your neighbors wifi could be on the same channel as yours and interfering, one of your devices could even be malfunctioning and sending malformed packets into your network, there are a slew of other potential network related issues that could be at work as well.
You could also have a badly coded app or driver installed causing problems on the hub itself.
The people here are pretty helpful and friendly, but your going to need to read up on pfsense and have a good grasp of it and a properly set up network first, before anyone can begin to help you diagnose a potential issue with your hub.
