I've been looking for a utility to scan my network and map the nodes. And then be able to run some speed tests between nodes, to try and find where bottlenecks might be. See which nodes are most active etc... Any such program? Otherwise, I just ran DSLReports speed test with these results: dslreports.com speed test result on 2006-09-26 16:03:22 EST: 2572 / 7 Your download speed : 2572 kbps or 321.5 KB/sec. That is 46.8% better than an average user on qwest.net Your upload speed : 7 kbps or 0.8 KB/sec. That is 98.8% worse than an average user on qwest.net Um, ya, that's a problem. Apparently my upload speed is utterly shot, and that's probably why all my Internet-connected apps have so much trouble. Pages will attempt to load, and then die, or I'll barely be able to use it at ALL, if at all. Assuming my download speed actually stays constant, or at least about that good. How can I find the upload bottleneck? This station is on wireless as well. I suspect other PCs on the network might be the cause, but I can't say. I need to test it all somehow. There are 3 wireless PCs and two wired, plus a network-attached printer. All XP, using Linksys hardware. Any ideas?
