Does Faster Internet Speed Increase Range?

Yes, upgrading to a faster internet plan should improve your Wi-Fi speed, but that's not necessarily the only way to improve it. If your Wi-Fi is slow, there are two possible bottlenecks: your internet service provider (ISP) or your router.

Does internet speed affect Wi-Fi range?

Internet speed does not. Your distance from the wiki router does not affect the speed your router can technically get data from the internet, but as it is unable to shovel the data off to you via wifi as its slower, hence you see a slower download.

Does internet speed affect signal strength?

How does Wi-Fi signal strength relate to data transfer speed? The data transfer speed increases up to a point as signal strength increases since higher signal strengths enable the use of higher PHY (PHYsical layer data) rates, also known as MCS (Modulation and Coding Scheme) in modern Wi-Fi.
