uses a standard telephone cable, whereas the network adapter uses a network cable, to connect to a local
area network (LAN). Do not connect a telephone cable to the network adapter, and do not connect a network
cable to a telephone line; doing so might damage the network adapter.

If your system has an external antenna, try moving the antenna to a better position. If the antenna is internal,
try moving the computer.
Try to connect again later, or contact your ISP for assistance.
