I am subscribed to an ISP supplying a 3meg ADSL line.
Lately (for the last 4 weeks) speeds have dropped from the usual average downstream speed of ~250kbps to just 0.14Mbps (according to speedtest.net) and employees are complaining about lack of access to the server.
I have been calling customer support and logging calls for the last 3 weeks, but they have been unable to determine the source of the problem other than carrying out a few bitstream tests and checking the DHCP renewal times.
I am going to call back and suggest carrying out a BER test. What type of equipment is needed to carry out this test? I have access to a wide range of Cisco networking equipment.
Other: We don't need a leased line as there are less than ten employees.
