Start of lockdown I ordered my brother an eBay $5 7m ethernet cable so he could run it down the hall from his WiFi router to desktop pc. He is in an urban apartment block and can literally see 50+ WiFi networks.... Greatly improved things. I had thought of powerline adaptors but last time I gave him a pair to self install he said they were too slow and on visiting I found he had managed to connect them to a flat three floors down through two electricity meters? An Ethernet cable was easier for him to self install
