Another super-cool thing about Netalyzr is that if you share the whole URL it gives you after the test, you get the stored results (that’s what the ID is for). So you can run it and give the results to a help desk, or have your mother run it and send you the link so you can see what it means. I’ve been pointing people to it a lot when I suspect they’re having NAT or such trouble from remote locations. Also, it’s fun to run in conference hotels and see just how atrocious the results are.

Yeah, I know. In any case, he determined this by running the below Berkely Netanalyzr tool while connected to wireless. This seems to be telling him that although his connection speed is pretty good, his uplink/downlink is buffering and could have dropped packet issues (see below). We get basically the same report when we checked this, however we were able to download a debian ISO while streaming some music with no problem. I think the buffering message may be normal, and likely would get worse as the AP gets busy. I'll do further testing myself, but I'm interested if anyone else has used this tool, and is this even a valid tool for measuring wireless performance ? Of note, I haven't seen the buffer issue when testing on 802.11n, but I need to get more test points there as well. The tool gives a lot of useful information, very cool. Unfortunately, it runs as a java applet, so no iPads or Galaxy support. http://netalyzr.icsi.berkeley.edu/
