As I am browsing the internet with good speeds, sometimes my connection just "stops". The blue bar in Safari just sticks at about 1/2" and doesn't move at all. I then solve the problem one of two ways: By quitting in and out of Safari multiple times until it works, or going into Network Diagnostics and going through clicking continue until it works. I have tried restarting(turning on/off) all three of the "pieces" involved in my home network, which are: -The older Apple Airport Extreme(for my iPad, iPhone, ps3, computer, and brothers xbox)--Not all on at the same time -The D-Link EBR-2310 wired router that spits out 3 connections, one to my dad's office, one to the computer in the loft, and one to the Airport. -Then the ancient source which is the Motorola SB4200 SURFboard Cable Modem. I don't even remember when or if we ever had another router(I'm only 16). Using Time Warner Cable. Anyway I have no idea what I am doing with networking really, and not sure what the problem is. There are the pics down below of the 3 devices and network listing. Any help is very appreciated and I will be quick to respond to any questions.
