I needed to buy a wireless router, so I bought one off eBay. I know, I know. When it arrived, it turned out they'd sent me a French one. The box gave specs and iirc the French specs were a higher frequency than the UK version. No biggy, I had an EU>UK adaptor plug and when it was all plugged in, it still worked, so far so good. But the WiFi connection does seem to be a heck of a lot slower than when I plug the ethernet thingy in. Does the French/English thing make that much of a difference? Or do I just need to get some kind of boosters, because the walls in my flat are quite solid, it's an older building, not a flimsy modern one, so I wondered whether that was an issue?
