Q: Why does my PC fall off line sometimes even with all
LEDs are in normal status?
The following scenarios may cause this problem..
1) Be disconnected by the ISP.
2) Some ISPs will have idle timeout setting to avoid wasting
IP. When the end user connects to the Internet too long
without any packet, the ISP will drop the connection.
Please contact with your ISP about this problem.
3) Some ISPs don't provide a good quality ADSL signal line.
Therefore, when the ADSL line is unstable, your
connection will be dropped. Try with a telephone and find
the status of your ADSL signal line.
4) If you have contacted the ISP and they promised the
quality of ADSL line, it may be the hardware issue and
please contact your vendor.
