I signed up for my ADSL 4 mbps service in june and i have been getting full speed till the beginning of August, now at the first hop of a tracert the ping jumps to 100 ms and I only get about 1mbps of throughput, I did try with another ISP and ADSL modem resets but the same results are produced. I did check the ADSL modem for the sync speed and it is syncing at 4096 / 507 kbps with an attainable rate of 9864/1052 kbps. I tried another modem and its still the same. Do you guys think is an exchange problem ?
