Hi I just need some help with wifi/WiFi extenders, I recently moved into a new room in the house that doesn’t get very good signal, if you’re near the WiFi I normally get about 100/110 but I get between 3 and 10 in the new room so I bought an extender and I’ve placed it relatively central in the house but it’s still only giving me between 10 and 20, should the signal be similar to the 100 I get closer to the box and another question will having a WiFi extender slow down the connection for people who are connecting the actual WiFi box?
