Ten Ways to Troubleshoot
Wireless LAN Performance
� Looking for obvious problems
� Moving your access points
� Moving your antennas
� Flipping channels
� Checking for interference problems
� Rechecking your environment
� Adding a better antenna
� Boosting your signals
� Going with a second AP
� Repeating your signal
� Checking your cordless phones
Although troubleshooting any piece of network equipment can be frustrating,
troubleshooting wireless equipment is a little more so because
there’s so much that you just can’t check. After all, radio waves are invisible.
That’s the rub with improving the throughput (performance) of your wireless
home network, but we’re here to help. And don’t get hung up on the term
throughput (the effective speed of your network); when you take into account
retransmissions attributable to errors, you find that the amount of data
moving across your network is lower than the nominal speed of your network.
For example, your PC may tell you that you’re connected at 54 Mbps,
but because of retransmissions and other factors, you may be sending and
receiving data at about half that speed.
