(2) Keep the HG520s away from appliances with strong electric fields or magnetic fields, such as a microwave oven or 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 10/100 M PCI network adapter and install the latest driver.
