I found it to be speedy enough for web browsing and email. However, downloading large files will likely be slower. I think each room is limited to a 1.5mbps speed limit. Which is comparable to your typical "cheap" DSL line.
If you're used to the premium DSL or Cable internet speeds, then it will be slower. It can't even begin to think about touching some of the fiber connections (FIOS or UVERSE).
Basically, it's fast and responsive enough for basic web browsing, email and other "light" internet usages. Downloading music, movies, Netflix streaming, Hulu, bit torrent and other such heavy internet usages will probably suffer from the speed.
