#1 Visit http://www.giganews.com/line_info.html and post up the Traceroute the page shows, if you wish. Be aware that the final hop (bottom-most line of the trace) might contain a hop with your IP address in it. Remove that line. What I'm looking for is a line that mentions "ERX" in it's name towards the end. If for some reason the trace does not complete (two lines full of Stars), keep the trace route intact.
#2 Can you provide the Transceiver Statistics from you modem?
If you don't know how to get the Transceiver Statistics from your modem:
a) What is the brand and model of your modem?
b) If you have a RJ-45 WSN port router connected to the modem: What is the brand and model of your RJ-45 WAN port router?
#3 Even if you know how to get the Transceiver Statistics from you modem, if you have a RJ-45 WAN port router connected to your modem
What is the brand and model of your RJ-45 WAN port router?
