I have 13.04 running, dual booting with Win7 (which works without issue.) Working with a direct network cable connection is fine. I'm fairly inexperienced with Linux.
I seem to be getting really inconsistant performance. Various other devices in the house (same location, or even further from the wireless router) perform far better (iPads, Droid phone, Wii, other laptops, etc).
I specified the BBSID from the pulldown, and disabled IPV6 as per other suggestions found... but they don't appear to have resolved the problem. Even loading simple search results from google are agonizingly slow. I've been using speedtest.net too for testing.
