Setting 1242 speed and duplex

Question

I have 8 1242 WAP's being controlled y a 4402 wireless lan controller. I was looking at the switch ports on my core switches and noticed that they are setting at 100 meg. I always set my switch ports manually to gig full especially when connecting to other gear like this. My question is how do I force the WAP's into gig full. I can find no where to set this manually. Auto seems to only go 100 half.

Answer 1

The APs are 100meg Ethernet.
Aside form that, when a connection falls back to a slower speed, or fails to function when forced to the higher rate (assuming both ends support the higher rate), then the problem is the cabling.
If the cabling is not terminated properly, (not using the correct pair order for example), or is is bent, kinked, twisted, or otherwise damaged, then the switch will downshift the speed to minimize errors.
In the case of a 100/Full port that only works at 10meg (or half duplex only), then it's usually a pair order issue, usually a split pair on pins 3&6.
10/100 Ethernet uses pair 3 (pins 1&2) and pair 2 (pins 3&6).
The most frequent cause for that is terminating the ends as pair> instead of the EIA/TIA spec (568a = green-whitet, green, orange-white, BLUE, Blu/Wht, orange, brown-white, brown ... 568b swap the orange and green pair).
If you map it out on paper, you'll see that pair> give you pin 3 as one color and pin 6 as another color ... meaning you no longer would be using "twisted pair" ... and the crosstalk spec (critical for high-speed signaling) goes right out the window.
Half duplex works with pair> because only one side is talking at a time, the crosstalk has no other signal to conflit with.
Check your in-wall cabling, use commercially created jumpers.
Good Luck
