Forgive me; I'm new to Macs and pretty ignorant about computers in general, but I've been having problems with Internet on my new computer. Pages load slowly or not at all, and sometimes they stop loading midway. I can't watch videos or stream any kind of music without it not loading completely. I tried searching for help and read that I could fix it by changing numbers in Network Settings under DNS Servers, but there's a number there already that I can't delete. ANYway, it's a MacBook 5.2 with OS X 10.5.6 Any help would be greatly appreciated!
