SBC Yahoo/AT&T DSL performance problems?
November 14th, 2007I’ve been fighting off and on performance problems with my service provider for the last few years. It’s one of those nagging issues where performance on my DSL would slow considerably, to the point where it was useless, and just when I got to the point where I was going to give up troubleshooting, a reboot of the router or something would magically make it go away.
Anyway, this happened again, and kept the same state for the last few days. I tried all the variables, and calling support is like going to confessional - “it must be your fault” “its something on your end, everything here looks fine” say the phone operator from Bangalore.
Anyway, after trying everything I was still convinced it had something to do with my provider so when I started researching and posing possible problems I found that a awful lot of people out there are having problems with SBC/Yahoo/AT&T DNS servers. A couple recommendations said that changing DNS settings from “auto configure from ISP” to OpenDNS would clear that up. So I tried it, and low and behold my problems magically disappeared. This would also explain why operators trying to test my line would not find anything wrong. Anyway, if you have this service, and have been dissatisfied with performance, try switching to OpenDNS. It’s free and if you aren’t very technical, they have pretty nice documentation walking you through step by step.
