I have a numbers of 1242 that when we set them up we used the GUI to configure them. Now we have gone back and seen that the channels we assigned to them are no longer there. They are now set back to Least Congested Channel instead of the assigned channel fo 1 6 or 11. Anyone else run into this?
I have read about this happening. Perhaps you can use the CLI instead;
This doc shows the IOS commands;
Hope this helps!
