Hi @giridhar26 ,
We're sad to know that you're having speed issues with the service, I'd like to confirm what devices are affected with slow connection. In the event its the devices connected via Wi-Fi, It is probably caused by Wireless Interference, here are some articles that you may find helpful.
Please see links below.
To get the actual speed we recommend to perform a speed test using a desktop/laptop connected via LAN/Ethernet cable.
Let us know how it will go.
