What to look for when buying WiFi Extender? (Buying Guide)

Look out for these things before making an purchase.


Higher the range, better the coverage area will be. Lets suppose if your router has range of 1000 sqft and wifi extender you have bought has 2000 sqft range, if placed optimally, you can cover approx 3000 sqft of total open area. So make sure to check before choosing, if you choose a extender lets say has 300 sqft of range it might not cover all the area of your houses but it will work well for small apartments. Ideally, you should go for 1000-3000 sqft range extender. But if you have pretty big area to cover then you might need to consider mesh wifi system in which you connect multiple mesh nodes with each other to cover the whole are or you going to need multiple extenders.


If Wifi extenders often comes with single band and dual band support. Dual band range boosters offer better speed as compared to single band but they are somewhat expensive. So, if you have pretty fast internet connection and your router support 5GHz band then go for extender which has Dual Band functionality.

Other Features

Some Wifi repeaters comes with extra features such as Ethernet Port or WPS push button setup. These features don’t have much impact or they don’t directly affect the functionality of the extender but they can be useful sometimes. So, if you can afford extender which has some extra features, go for it.

How To Connect Wifi Extender To Spectrum?

In general, connecting an wifi extender to any router is pretty easy. You just connect the extender to power supply, then configure it using its web console or app. Additionally, all range extenders comes with user manual inside the box. if you ran into problem just follow to instructions to set up the device.

Can I Use Any Wifi Extender With Spectrum?

Theoretically speaking, almost all wifi extenders are compatible with spectrum routers. But if your extender won’t work (which is highly unlikely) you can always call the support or claim the warranty. They sure will help you with the issue.

Does Wifi Extender Slow Down The Internet?

Normally, Wifi extenders don’t slow down internet speed. If you feel slow speed, first read the instruction manual and check if everything configured properly. Make sure your extender is not too much far from the router and if your extender is dual band then make sure 5GHz channel is enabled.
