Diagnose a weak Wi-Fi connection with netsh wlan
On a canned Windows client, run netsh wlan show interfaces to read the current signal (42%) and channel (6, so 2.4 GHz), then netsh wlan show networks mode=bssid to scan the visible networks and BSSIDs. Observe several BSSIDs on channel 6 and a stronger channel-44 (5 GHz) BSSID of your SSID. This is a client-side point-in-time view and a hypothesis to test (possible co-channel contention; test the 5 GHz band), NOT a site survey, and it does not prove the cause or the fix. Do not claim this canned adapter or network is real. This page teaches a job procedure. These are not exam questions, this is not a score predictor, and nothing here is taken from any certification exam.
Steps
- 1
Run netsh wlan show interfaces. Note Signal 42% and Channel 6 (channel 6 is 2.4 GHz).
- 2
Run netsh wlan show networks mode=bssid. Note other BSSIDs on channel 6 and a stronger channel-44 (5 GHz) BSSID of RTJ-Office to test.
What you should see
show interfaces shows 42% on channel 6; show networks mode=bssid shows channel 6 shared by several BSSIDs and a stronger channel-44 (5 GHz) BSSID of the same SSID. That is a hypothesis to test, not a proven cause or fix, and not a site survey.
