Recently, we had a vendor come into our organization to implement a new wireless cart for nurses and they recommended we change our wireless config in the building that these carts are going in, due to their wireless carts not working properly. Up until now we have not had any issues with any type of client on our WLAN. We've built our WLAN on Cisco's best practices. But, this vendor is telling us things that contradict what Cisco says. The vendor had us change the following...
1. We turned RRM off. (They said AutoRF is a immature feature in Cisco's current feature set)
2. We Hard-coded all AP's with channel/power settings.
3. They told us using 802.11a was not a strategic move and to use b/g. (they were using a card that didn't support a)
4. Then they said turn off RF Grouping.
These are the 4 things that they recommended, we were wondering what everyones thoughts were on this vendor's recommendations?
