Ping time slow with 2.4GHz

Support, 

   I am having issues connecting the Blink Sync Module ( for security camera ) to xFi. I ran a trace as suggested by Blink Support and when they reviewed the results, they found out that the ping time from the router to the External Network Connection took 40ms. I have the screen image to show proof.They said the ping time should not exceed 20 - 30 ms. 

    I have been trying to get help through online chat. Until now, I am still having issues.

    Can I please have someone from the real Technical Support help me ? Is there an issue with the xFi Gateway  that I got ? Is there an issue with the antenna ? 

    Please help.

Thanks,

Ofelee
