My Earthlink DSL is very slow and I'm trying to figure out what the problem is. I thought I would start by asking if my 10 year old modem could be the problem. It's a ZyXEL P-600. ATT Airport Extreme (A1301) MacBook Pro/iPad/MacPro '06/iPhone 5 (which is MUCH faster than the wi-fi)
reply to moon man Yes, I have a lot of problems these day. Maybe I need to move to a different company. I have used them over 16 years and did not have any problem until one month ago. Their system must be had changed. I don't think it is the modem.
