Aironet 2600i Throuput issue in 2.4 GHz

[helpling]

Hi everyone.

recently we increased Internet speed up to 200 Mbps. through 5GHz Radio and LAN, I can get the 180 up/down the speed. but on 2.4GHz, still, it's 98 Up/Down.

does anyone have suggestions?

Hi @helpling 

Your configuration looks fine, not sure if you are using channel bonding on 2.4 GHz, still, if you use bonding you will have an issue with your plan channels. I think this is a physical limitation on the 2.4 GHz band.

What device are you using to connect on to the 2.4 GHz?

Hi @JAYESH RAMAIYA 

I always follow "Cisco Wireless LAN Controller (WLC) Configuration Best Practices"

In general, Disable low data rate, use 20 MHz width, if you're using PSK then use WPA2 with AES-CCMP.
