I have several RPIs all connected together via Ethernet cables and a switch. They are talking to each other fine and are configured with static IPs. This works very reliable and so far no problems.
However, the WiFi gives me fits. Using Chrome, some days websites load up fine, other days, not so much. For example, this morning, I wanted to install some software on it, I couldn't get to that website but I was able to get to Yahoo, and a few other popular websites. The net result is that I could only get onto a few websites and most others came up with the msg. "this site can't be reached"
I am pretty sure it is something with how I configured things with the static IP for the Ethernet port but beyond that don't know what to look for to fix this problem.
