Not getting apt coverage with isp provided router? If you have made up your mind to upgrade the wifi network. The Biggest question that arise is should I get a range extender or get a proper mesh router system? We’ll help you answer that today.

If you have multi story house or house with area greater than 2000sqft of area. If you are unable to place the router in center of the house. If your isp provided router heats up or gets slow on heavy usage. If any of the above answer is yes then better opt for a Mesh router.

If you are getting almost good coverage but only one room or small area need to be covered. If you live in a small single floor house or apartment with area of less than 1500sqft. If your isp speed plan is less than 75mbps and don’t plan to upgrade in future then wifi range extenders can be your friend.
