Question

Poor range on new Cisco 1252 b/g/n access points: any tips?

Asked by: skipervarg

We recently purchased a couple of the new Cisco 1252AG Aironet APs (802.11b/g/n). They have separate 2.4 and 5Ghz radios.

Out of the box, they seem to have very poor range. I have the radio power on them set to max but the signal is so poor. My laptop (Dell D430) is situated just 3-4ft from it and the signal is -15db...half that of a apple airport sitting further from me (-31db!). The range seems very poor. Am I missing something? I get the same results from both of the APs and when I use different laptops (Mac, PC).

Do you have an external antenna connected to each of its antenna ports?
Is each antenna connected to the correct connector? i.e. the frequency for which the antenna is designed?
e.g. did it come with 2.4GHz and 5GHz rubber ducky antennae for all 6 connectors, or were there none, or 3 (how many of each band?), or what?

Hi Darr27, yes you were on the right track :)

It turns out that model does not have an internal antennae. It did not come with any "rubber duckies". As soon as we added some antennaes, the signal looked great.

Thanks for the help.

^he's right. did you resolve the issue?
I would also try reducking the TX power of the access points. the AP can actually be "talking to loud" for the clients as I understand it.

I would test a few more PC's b4 i introduce the MAC's
