    Thanks for the timely response.   Sigh that i had purchased the correct product to get Giga speed.

     

    However, when I test Wifi (5 Ghz) connection; barely i am getting around 270 - 290 Mbps... 

     

    Is there any settings that i need to modify to get maximum speed.

     

    Thanks

I haven't looked at the C6900 specifically, but you should get more than 270~290 downstream bandwidth on the 5Ghz broadcast. 

 

Are you getting "full speed" on wired connections?

 

Please disable, QoS, SMART Connnect and / or Traffic Meter if enabled.  Restart the modem and retest. 

 

Also suggest you not use "Auto" for broadcast channel and select something "open" or the least used in proximity to others.  See my other post here.

 

Others have also recommended a modem reset after a speed increase, as the modem does do some relearning.  Not sure if this applies in your case.   

 

FW is pushed to the device duing registration and provisioning by the ISP.  You may want to check that you have the latest FW available for your device.  Here

 

However, I would expect this to affect your wired performance and not the wireless. Your issue is likely related to a setting or something else.
