As with other wireless G networks, you should be concerned with the typical interference issues, such as neighboring APs being set with an interfering channel and interference from other radio or electronic devices.

However, wireless N throws another problem at you. Remember that if you change the default channel-width from 20 to 40MHz (to try for greater speeds), it doubles the frequency range of the transmissions.

If you do use channel bonding, you're limited to using two of the typical three nonoverlapping channels.

So you should make sure you're using only channels 1 or 11 on all your APs.

Plus check the air waves to see there are other networks in the area and select the channel accordingly.
