Everything You Need to Know About Wi-Fi Extenders

If you've noticed that when you walk to specific areas of your home you lose your Wi-Fi signal, then a Wi-Fi extender could be useful. A wireless range extender works with the wireless router you already have set up, and it improves the coverage and performance of the existing signal. eBay is proud to offer many affordable Wi-Fi extenders and boosters from a range of trusted brands.

How Does a Wi-Fi Extender Work?

A wireless range extender will take the signal broadcasting from your router and repeat it so that it can reach to surrounding areas. Dead spots are unavoidable in many homes, but a Wi-Fi extender can help with spaces in your home where the Wi-Fi struggles or where the signal doesn't reach. The extender creates a new SSID (service set identifier), or network ID, that you can connect to in the trouble spots of your home.

Can You Have Two Wi-Fi Extenders in One House?

You can have two wireless range extenders, but you do not want to have them connected to each other. Therefore, you should connect each extender to the main router of the house so that they perform independently and at optimal speed.

What are Some Reasons to Get a Wi-Fi Extender?

There are several reasons you may need a wireless range extender from eBay. These are a few of the most common causes:

  • Dead spot: Your Wi-Fi may not be able to penetrate a wall or between stories of your home.
  • Hard-to-reach areas: There are places in your home or on your property where you want to extend Wi-Fi or wired internet coverage.
  • Multiple devices: You have more than one device or gaming console, and you want better coverage for playing and streaming.
  • Faster data transfer: You want to improve the speed of your 802.11ac connection to places in your home where it is hard to reach.

What is the Difference in Speed Between Single- and Dual-Band?

With all Wi-Fi extenders, the rebroadcasting of the wireless signal from the router changes the connection speed. If you have a single-band extender, you can expect slower speed than if you have a dual-band extender because the repeater has to get the signal and rebroadcast every packet of data using only one radio channel. Dual-band repeaters are faster because there is one radio channel for speaking to the router, which gets done on lower channels, and one receiver for retransmitting on the higher ones.

Wi-Fi Extenders and Gaming

If you're into gaming on a PC or console, you may find you're getting high ping or lag when playing games online depending on where your set-up is in your home. If your PC or console is in a room without good Wi-Fi reach, a Wi-Fi extender will likely do the trick to ensure you're getting good coverage.

Certified Refurbished Computer Modems

While eBay offers buyers the choice between both new and used items, there's also a third option that may interest you: Certified Refurbished. Certified Refurbished items are sold by eBay-approved sellers and are often available at lower prices than buying new. Each of these Wi-Fi extenders comes with a like-new guarantee (including accessories, instruction manuals, and packaging), a free return/replacement policy (within 30 days of receiving the item), and a 2-year hassle-free warranty. We also regularly monitor our sellers to ensure they're meeting our stringent quality control metrics, so buyers know they're only getting the best.
