You go to the Wireless tab, then under Access Points in the left-hand menu hit 802.11a or 802.11b/g to see the channel allocation and power level for each AP.

To manually adjust the power level and channel click on the arrow at the right-side of each AP's statistics and hit 'Configure'.

Under channel they all say 36* and power level 1*.
Is that right? should this be adjusted?

It is right if the WLC says that.

Can the APs 'see' each other?  If not this is fine.

How would I know if they can? If they do do I need to adjust something?

Commented:
If they can see each other the WLC (RRM) would usually adjust the channels and power levels dynamically.  The fact that they're all on the same channel and power-level 1 says to me that they're too far apart to be interfering with each other.

As long as you've not played with any of the RRM or general radio parameters you don't need to do anything.

So the WLC will adjust this automatically? If it doesn't what sort of problems will we see?

Commented:
By default the WLC will collate the RF information it learns from each AP and use that to set channels on each AP that it manages.  It will also set an appropriate power level.

If the WLC didn't do this you would potentially see lots of problems.  The importance of what the WLC does in terms of RRM (radio resource management) though is that it manages its own RF parameters so you don't have to.  For a straight-forward deployment where you have APs dotted all over the place a fair distance from each-other you can just let it do its thing.
