That one for 1242AG not 1242G;;;; (((, my AP is 1242G , I increased the gain , I used as dummy suggestion 5GHs antenna, I have changed also the power transmition , relocation , I turnd off all AP arround this AP to remove any kind of interference , I forced the AP to use channel 1,3, and 11 , also to use channel 10 also the same, the area only around 10 meters.
I used deferent wireless clients BB, Windows, CUIC, IPhone, etc
what antenna are you using?
for this AP two ports only for 2.4 ,
Dual RP-TNC antenna connectors for 2.4-GHz radios
but I dout in one thing , the2.4GHz antenna for this AP similer to the 5GHz antennas for 1262 AP,, some thing strange
what is the part number of the antenna.

I need to know the part number of the antenna, we know the AP.
it should have been on the packing the antenna came in.
than either your antenna went bad, which can happen. Or it's a 5GHz antenna.
Do you have another 1242 you can take the 2.4GHz antenna off of and test?
