3. Check that the security mode of the wireless network is set to
WPA2-PSK, or WPA-PSK/WPA2-PSK, and SSID is set to SSID1.
Note that the WPS function is forcibly disabled if the wireless network
uses the Wired Equivalent Privacy (WEP) encryption.
4. Check the positions of the HG658d and the computer. Ensure that they
are far from the electric appliances such as microwave ovens,
refrigerators, or cordless telephones that generate strong magnetic or
electric fields.
5. Place the HG658d in an open area.
Although radio signals can pass through obstacles, their transmission is
affected if they pass through too many obstacles such as walls.
What can I do if noises exist during telephone calls?
1. Check that a splitter is installed.
A splitter helps to protect the ADSL call quality from being affected due to
the interference of other signals.
2. Check that telephone lines are securely connected. In particular, ensure
that the telephone line connecting to the splitter is securely connected.
3. Replace telephone lines and ensure that the telephone lines are not
faulty.
After a broadband device is installed, does Internet access degrade call
quality or do telephone calls lower the Internet access rate?
No. The HG658d uses the frequency division multiplexing (FDM) and splitter
technologies to separate voice signals from data signals. Although these two
types of signals are transmitted through one telephone line, they are carried
by different frequency bands. Therefore, they do not interfere with each
other. In this case, you can make telephone calls and access the Internet at
the same time, without degrading call quality or lowering the Internet access
rate.
