I have approx 20 Cisco Aironet 1300 AP's that I use as Bridges to connect Various wide-spread, non-adjoining offices together. I do not have any problems as such, but obviously, some of the connections are stronger/faster than others due to various factors. But 1 thing I have noticed is that some of the AP's radios are rated (Transmitter Power CCK/OFDM) at 50mw and some at 20mw, and generally the 50mw AP's link seems to be faster. Therefore I have tried my best to upgrade the 20mw to 50mw - matching the radio settings, upgrading the IOS - but it doesn't change. All the AP's were purchased at roughly the same time and from the same vendor.
I have tried a few IOS's, but most of the AP's have 12.4.3g.
Can anyone explain this and/or help me upgrade to 50mw if it is possible.
