You are welcome.
Your Wifi issues will have no effect of satellite TV reception. They are not usually connected. Some Satellite TV receivers do have an internet and / or internal WiFi network connection, which is mainly used for downloading software updates for the receiver.
There are two distinct considerations with accessing the Internet and Wifi.
1. Your download / upload speed is primarily limited to that supplied by you Internet Service Provider (ISP). If there are lots of people connected (branched off) to the cable service to your area, the available bandwidth will be shared. Imagine a water supply being split between a lot of houses. As each house turns on a tap, the available shared supply reduces. In addition, the TRUE available bandwidth delivered will depend on any limiting device that the service has to pass through (a local hub for example). Using the water analogy again, imagine that the supply had to pass through a very narrow pipe at some point. That would reduce the available flow. :)
2. The WiFi signal in your home is generated by the Router which is connected to the cable providing the Internet service. Some Internet services are connected to homes / client properties via microwave links (Compusurf for example). There will be a receiver on the roof and a cable down into the property.
The sighting of the WiFi Router in the home can have a dramatic effect on the available signal in the house. Particularly if the signal must pass through walls (especially walls with steel reinforcement). Having a Wifi Router placed in a corner can also sometimes cause issues.
There are WiFi boosters, which can be placed around the property to help with the 'black spot; issue. In addition, devices which are fixed in position, like a smart TV for example can be connected directly to the Router by a wired Ethernet connection. There is a kit available to do that with a Firestick if need be.
It is very easy to end up with a fairly complex installation if care is not taken. :)
