Main issues are:
1. Roaming is all over the map. If a user is on the NE side of the building (4 APs away) they will sometimes roam to an AP in the SE corner of the building. Very odd. Lots of retries both in/out.
2. New network adapters like the Intel dual band wireless-ac 7260 have throughput issues. I can't get much speed out of them, but older legacy cards to 2-4x's as much throughput. The 7260 has been a known card with problems and I have been diligently updating firmware and connection settings as Intel releases new info. Throughput isn't any better but they don't seem to drop as much. They also roam all over the place and often don't connect to the nearest AP.
3. Drops and connectivity problem reports have really been coming in a lot over the last week or so. I've rebooted the APs to refresh connections but that didn't seem to do any good. We do have some Noise related issues and some Neighboring AP interference but I'm unsure how best to filter these issues out.
Thanks.
