I am planning on building a gaming PC soon and I need some help getting an Ethernet connection. The PC will be in my room which is 1 floor above where the WIFI modem is (pretty much right above it). I've been thinking of buying a WIFI extender which has an Ethernet port and connecting the Ethernet cable from the extender to my computer. Will this solution cause my download/upload/ping speeds be greatly reduced? Will just using a USB WIFI adapter give better results?
