The Droid 2 can connect to 2.4 GHz wireless networks, such as 802.11b/g/n, but not 5.0 GHz networks such as 802.11a/n. Why is this? Is there any workaround to allow it to connect to both types of wireless-N WiFi networks?
Note, this is similar to a question that was recently deleted by its owner and I didn't get a chance to answer. Hopefully this will be useful to others in the future.
