I am currently using a cheap wifi adapter in my desktop. I have a new router and I am about 35-45ft away from it in a seperate room by 1 wall. My connection has been spotty the past 3 weeks and I think its about time I try and fix it. Would something like a better/more expensive usb wifi adapter work or should I be looking into wifi extenders? The adapter I currently have is "EDUP AC600M USB Wi-fi Dongle 802.11ac Wireless Network Adapter with Dual Band 2.4GHz/5Ghz High Gain Antenna". Any input is greatly appreciated because I do not know much about this topic.
