6 months ago I bought TP-Link N450 Wi-Fi Router ($24 at Amazon) that has three long antennae poking upward. Now I get wifi connectivity on my laptops, that is the same as using Ethernet cable to my desktop. 100mbps these days for wired and wireless
TP-Link N450 has been around since 2011 or so. I bought new because I was assured of getting the latest version, which is version 6.0.
You will see used ones at eBay going for $11. They might be only version 3.0
Dual band router means your new router will also operate in 5G in your house. So I got ye old single band router / TP-Link N450 / that has no stinking 5G
