Why does the ADSL connection get broken so often?
Many possible factors may cause this problem, such as faults in
your ISP's access server, line disconnection, and line disturbance. You
can check as follows:
(1)
Make sure that the ADSL line is connected properly.
(2)
Keep MT880 away from appliances with strong electric fields
or magnetic fields, such as a microwave oven and a
refrigerator.
(3)
Make sure that no telephone or fax machine is connected
directly to the ADSL line.
(4)
Replace the old ISA network adapter with a new 10/100M PCI
network adapter and install the latest driver.
