I have seen this in some of my buildings. Check the signal strength on both a and b radios. The a radios are typical higher power than the b radios because the b's have more interference due to less channels to cover an area.

Any ideas as to why this may have happened? While I already planned to add more APs in those areas a part of a 802.11n rollout, I would like a better understanding of the why the upgrade would have affected the APs in this way.
