The Issue
Recently, my computer has taken to connecting to weak APs on the network. Starting earlier this week, I noticed a significant drop in network quality (From 40 Mbps to 4 Mbps tested using speed test sites).
My investigation revealed that the computer is connecting to what appears to be weak BSSIDs within the SSID group. I suspect that these BSSIDs belong to routers on the floors above and below me. Running wlan show interface
in netsh
reveals that Windows detects these weak BSSIDs have a quality of 99%. Because of this high quality, Windows priorities these BSSIDs. However, the quality of the signal immediately drops to ~60% as soon as there is traffic on the connection.
Due to these circumstances, I have several questions:
- Why does Windows give the weak BSSIDs a high quality?
- What could have changed to cause this issue (as it was working fine before)?
- What are possible solutions to ensure I connect to the actual "best" BSSID (ideally fixing the fact that Windows rates the weak APs highly)?
Other Details
- The computer uses Intel's Dual Band Wireless-AC 7265 adapter (Which has up to date drivers)
- No updates/new software packages were installed when this issue began.
- I assume my other devices (Phone and Tablet) pick the right BSSID every time, since they show ~40Mbps.
- I have tried using Intel's connection tools to pin the BSSID to one which I know performs well, however it does not seem to work.
- I have tried increasing the roaming aggressiveness of the wireless driver, but this yielded similar results.
