I'm trying to diagnose some internet speed issues on my MacBook. It's happening everywhere I use the internet -- at home (Comcast), at work, at my favorite cigar store. (All are wireless.)
At first, when it was home, I thought it was my service, as my XBox 360 was also exhibiting some internet speed issues. I bounced the router, and the 360 was fine -- but the Mac was not. (Plus, once I got the machine to work and the cigar shop today, it's still exhibiting the behavior.)
The behavior itself is odd -- once a host seems to be found, speed is no longer an issue. (In other words, download speeds themselves are fine -- but getting the request to the server is the issue.)
My gut reaction is that I'm having a DNS issue.
Any troubleshooting advice?
On the advice of Josh, I tried a Speakeasy test. Once the site resolved, the speed here at the cigar store was reliably 20+mbps up and 3+mbps down. I expect my home environment to be similar when I get back tonight. As stated above, the issue isn't the download speed itself -- it's the resolution. I may try Am1rr3zA's advice of setting my own DNS if this continues to be an issue. Still soliciting other ideas, however!
