Hello Ubuntu world!

I am completely and utterly new, so stick with me here.

I have a desktop computer that I had Ubuntu 10.10 loaded on. Started it up after about a year and upgraded gradually to 12.04 LTS.

(I want to post specs, but how do I do it in the fancy scroll box?)

Anyway, I have noticed extremely slow internet speeds since day 1. I just got done reading a popular post about MTU and RMEM, etc., and have tried adjusting but I'm afraid I'm completely lost.

Currently purchasing a 1.5M connection (bottom of the totem pole), and average download speeds of .50M down. Sometimes far, far less.

Noticed that interface in use is "lo" not "wlan0".

Help!
