I'm Netplus wifi from a long time and from last 2 months. I'm continuously facing slowness issue. I had raised this query to my local operators but they are not trying to solve the problem.My wifi plan is of 100mbps but it is providing me maximum 20 mbps or less.

I have called netplus customer care and they told me that it will be solved but after all it still not providing me my full speed.

And i don't know if it is a technical problem or my modem's problem. So, I want to please send a techinican who can check both the techinical problem and my modems problem.
