That's one thing I definitely miss from DSL, the upload speeds of 768K to 1M, and the stability. I may have 5Mb/s now on cable, but it's rare to see more than 3.5Mb/s or so max down—more often than not I'm lucky to see 1Mb/s (darn shared connection)—if it is even working to begin with. The max upload I've had is usually 20K, 30K if I'm lucky. Absolutely annoying and way too slow if you ask me.
Scott, are you on standard cable or fiber-based cable?
