Hi all! Basically my problem is this. I have a fibre optic broadband connection with Virgin and the wifi connection on my pc is fine, probably because my pc is in the room above it. My sister's connection is bad even though her pc is in the room next door to mine. We hooked up her pc wirelessly to a wifi repeater and she gets a good strong connection. My brother on the other hand gets a very unstable connection. Sometimes the signal is weak and the connection often resets. He got a NETGEAR A6210-100PES AC1200 802.11AC Dual Band (300 Mbps / 867 Mbps) High Gain Wi-Fi USB 3.0 Adapter and that has helped with signal strength but the connection remains unstable. The way the house is built, his room is an exterior one so I think that may play a role. But I'm not sure. Can anyone help with this? Do I need to get him a specific bit of hardware so that he has a stable connection? Or do I need to start drilling through the floor so he can connect with a LAN cable?
