A single 802.11g access point has been configured and installed in the center of a square shape office. A few wireless users are experiencing slow performance and drops while most users are operating at peak efficiency. From the list below, what are there likely causes of this problem? ( choose three)
A. mismatched TKIP encryptionB. null SSID
C. cordless phones
D. mismatched SSIDE. metal file cabinets
F. antenna type or direction
Correct C,E,F
Explaination :
C : if you have cordless phones or other wireless electronics in your home or office, your computer might not be able to "hear" you router over the noise from the other wireless devices. To quite the noise, avoid wireless electronics that use the 2,8GHz frequency. Instead, look for coordless phones that use the 5,8GHz or 900MHz frequencies.
E : The antennas supplied with your router are designed to be omni-directional, meaning they broadcast in all directions around the router. If your router is near an outside wall, half of the wireless signals will be sent outside your office, and much of your router's power will be wasted.Tips and Trik CCNA
