Double-click on UOTRACE.EXE to run the program.
Click on OPTIONS, then ADVANCED.
Choose the server you wish to trace to from the drop-down list. (This is where you can also just enter the name of any site you want to use as a test endpoint.)
Click the TRACE ROUTE button. A succession of host names will begin to appear in the main window. These are the computers your data passes through on its way to the desired server. Once the function is complete, a message that says “Traceroute successful” will appear in the lower left corner of the window. If you get a message saying “Maximum number of hops exceeded” click on OPTIONS then SETTINGS and change the max hops to a higher number and re-trace.
Click the POLL button.
This tells the program to send multiple packets of data through the route to the final host. As the data is being sent, look at the PKTS R/S column. Let it send about 100 packets then select STOP POLL.
If you want to copy the results to post on a forum, click Copy in the Edit menu, then paste it where you want it to go.
When you are experiencing latency issues, you’ll probably see that your first few hops are fine, with very low round trip times, but then at some point you’ll hit a router that is responding much slower than the previous ones. You’ll probably notice that all the hops after this point have high latency. That hop, or the one just before it, is the problem. You can get this data to someone at your ISP, and if they can filter it up to their network department, they should be able to take a look into the problem.
If you see packet loss to every hop past a particular hop, the first hop with loss is probably the problem. (All packets to hops past the first one with loss have to pass through the one that is dropping packets.)
If you see packet loss pretty much from start to finish, it’s probably an issue with your cable/DSL modem, or possibly your connection itself.
