Having trouble keeping a stable connection to your Wi-Fi network at home? The TP-Link N300 Wi-Fi extender can help change that, and today it's on sale for just $13.99 when you clip the $3 off on-page coupon at Amazon. We shared a deal on this range extender about two months ago when it dropped to around $15, but today's the lowest we've seen. It sells for just under $20 on average and is an inexpensive way to enhance your internet connection without buying an entirely new router.

The N300 uses your 2.4GHz Wi-Fi band to extend a weak wireless signal in a spot of your home that might not get any at all. It has a limitation of 300Mbps but something is better than nothing, and this is designed to work with pretty much any standard router or gateway. It has an Ethernet port you can use to directly connect to the device for something slightly more stable. It comes with a two-year warranty. More than 18,000 users have tried it out and give it 3.8 stars overall.
