I work for a business that is on a university campus. For two years I've been working on the network (dedicated T1 line from our building) with macs for over 2 years. Starting last month I noticed a slowdown in my outbound bandwidth. I had trouble downloading things off of my work G5 from home using my powerbook, and at work I have issues uploading files to various offsite servers. In fact it seems that I can't upload at a rate any faster than 10kb/s I can confirm the following. The issue is not my cable connection from home. The issue does not appear to be the network card on the G5, I took the computer home and it works fine. Also I brought in my laptop and connected it to a different jack on the network and got the same results, where my upstream was slow. The PC's on the network are not experiencing this issue. It is only an upstream bandwidth problem, can receive/download fine. I contacted the system admin at the university who insists he's made no network changes despite the fact that everything worked fine until march, when I believe a firewall change took place. I'm hoping someone can recommend a utility or some way that i can help the system admin solve the issue. Thanks.
