I have just been on a longer walk using the grid option and the AP's
that were located correctly have in the majority moved to the edge of
the grid along with 48 other AP's, which has left just my router and 2
other AP's in the correct position. Because there are so many AP's
listed some are actually overlapping each other, which is very annoying.
However when you check the signal map for each AP you still get a
varying colour scheme, dependent on the signal strength, unlike the
single colour that was shown when using a map. |
