1.  Make sure the antennas are attached correctly.

2.  Check for radio interferrence.

3.  Check and ensure the client wireless NIC card has the latest drivers.

Re: aeronet performance issue

Which band (2.4G vs 5G) do you use? How many antenna do you install on the band? By default, AP1242 uses two antennas to avoid multipath problem; so that antenna diversity is used. If you only have one antenna, you need to configure antenna receive left and antenna transmit left under dot11radio<0/1>

If possible, collect the output of show dot11 as all and look at the signal strenght. Ideally range is between -60dBm to -70dBm. Anything between -70dBm to -80dBm is fairly. If you have anything below -80dBm, the signal is not good enough for stable connection.
