Re: [Line Problem] Bizzare DSL problem - some sites load, others
said by mrcutter:Correct, but that shouldn't cause site loading problems UNLESS you were having heavy CRC errors. Sites that have a lot of advertisements pulling in from advertising servers around the country could have troubles loading.
Just did a little searching - am I correct that the 6dB downstream noise margin is "really bad" and that the 17.4dB of output power means that the DSLAM is effectively "screaming" to try and hit my modem?
Alternatively your traffic to the problem sites might be having problem with the servers and backbone in between.
Ping problems would tend to favor the latter suggestion. Tiny pings usually aren't affected by CRC errors. They slip through.
Try tracerts to the sites and compare the routs of the good with the bad.

DL - when I look at my details log for the broadband connection I see zeros across the board and no indication of a real communication problem. I am increasingly convinced there is a problem with AT&T's network in Cleveland, and it's an insidious one at that.
I use the term "insidious" because I think a lot of people are used to the network status as a one or a zero - it works or it doesn't. When some sites work and others don't, it gets put into an odd area in between. Some users may, by luck, never see this problem, and others may see if all the time.
I am hoping to gather more information, then make my case to AT&T over in the direct forums. I appreciate the complexity of networking, and want to provide time to gather information that may be able to assist AT&T's technicians and engineers.
