Re: How to show ALL nearby Wi-Fi AP's BSSID every time

I added a better output summary. I tried to get a RSSI histogram, 
but it was just too cumbersome; so I backed off & just added counts.

It's a bummer that Windows isn't reliable in outputting all the 
access points nearby in a single command, but this works reasonably.

 REM This is C:\data\sys\batch\netscan.bat version 2p1
 REM Logs the fullest list possible of all nearby Wi-Fi APs
 REM v1p0 20251213 outputs wifi adapter AP cache to a log file
 REM v1p1 20251213 disconnects/reconnects Wi-Fi, then outputs AP cache
 REM v1p2 20251213 captures multiple snapshots for the fullest AP list
 REM v1p3 20251213 captures multiple AP scans with timestamps for each
 REM v1p4 20251213 build a consolidated summary of the full list of AP's 
 REM v1p5 20251213 count the unique BSSIDs and SSIDs found in the AP scan
 REM v1p6 20251213 add a summary of BSSIDs and SSIDs found per scan
 REM v1p7 20251213 add a signal-strength histogram via PowerShell
 REM v1p8 20251213 separate scan results into files for better counts
 REM v1p9 20251213 tried to create histogram using PowerShell but failed
 REM v2p0 20251213 reverted to 1p6 and created tmp files to fix counts
 REM v2p1 20251213 added per-scan BSSID counts along with the SSID counts
 REM Note: Without admin, we can only toggle known Wi-Fi profiles
 REM Note: Use netconnect.bat for a more powerful adapter reset with admin
