There is no such thing as a WIFI provider. Internet service providers give their customers Wifi.
17 mbps is awful. I have, and use 200 mbps, and I think it's good. If you get 200 mbps, or around 200 mbps, then when you use your internet, you should be happy.
There are different Internet Service Providers. I heard of only 1 Internet Service Provider that's very good, but according to the currency you are using, I don't think you will be able to get any of the internet packages that they offer. Because you don't live in the same country as the Internet Service Provider.
