❑ Microwave ovens operate in the same frequency band as the
802.11b HR radio; therefore, if you use a microwave within range
of your Allied Telesyn RF network, you may notice network
performance degradation. Both your microwave and your RF
network will continue to function, but you may want to consider
relocating your microwave out of range of your access point.
The access point features an advanced configuration
parameter for the 802.11b HR radio called microwave oven
robustness. You can enable this parameter to minimize
potential interference between your microwave oven and
your RF network.
