Best settings for home Cisco 3702i AP

[Andrew White]

Hello,

I am running a Cisco 3702i AP at home with an up to date firmware.  It was using PoE into a Ubiquiti switch, but complained it wasn't getting enough power, but connectivity seemed ok, although upstairs it wasn't as powerful.  I've added a power injector and it's made no difference.   Is there a setting to increase the power?

I have 2 SSID 1 on 2.4Ghz (channel width 20) and the other on 5Ghz (channel width 80).

Also what are the best data rates for each?  Or anything else you might recommend?

1. Disable low-speed data rates on both radios. Disable from 11 Mbps and below. Make 12-, 24- and 48 Mandatory and the rest are Supported.
2. Use 40 Mhz channel bond. Don't believe in the hype: 80- and 160 Mhz will only ruin the wireless network.
3. Keep the amount of SSID as low as possible. Recommended number is less than 4.

for the POE draw needs to provide 802.3at POE to the AP otherwise it will turn off radios

http://www.cisco.com/c/en/us/td/docs/wireless/technology/apdeploy/7-6/Cisco_Aironet_3700AP.html#pgfId-99003

The AP 3700 with integrated 802.11ac wave-1 radio is designed to run from Power over Ethernet (PoE) sources, local power, or via mid-span or power injector. If the AP 3700 is powered by PoE and the source is 802.3af (15.4 Watts) the AP will come up and fully function in a 3x3:3 mode, for enhanced performance additional power sources such as 802.3at, enhanced PoE, Cisco PoE Injector-4, or local power may be used. With additional power (greater than 15.4W) supplied, the 3700 will shift into the 4x4:3 mode.

If the customer has lower PoE requirements and still wishes to use the AP 3700 and say the WSSI module, the AP 3700 will still function with the module but in a 2x2:2 mode with the module enabled.

How can I check I’m using 3x3:3?

[patoberli]

You can't really. But if it states Full-Power, then you should be good.
The thing with the 3702i (and most -i models), they are built for high density and not really long reach (my personal opinion/experience). Make sure to manually set the 2.4 and 5 GHz interface to the highest power setting.

[Andrew White]

Where would those settings be in the GUI or CLI, I just can’t locate these power settings?

Here is a manual:
