Diagnose Piso WiFi in layers: power → WAN internet → controller LAN/DHCP/DNS → access point → captive portal → payment/session. “Connected to Wi-Fi” does not prove the WAN or portal is working.
10.0.0.1 is a private address commonly used by Piso WiFi captive-portal/vending systems, but it is not a universal admin address for every machine. AdoPiSoft officially documents 10.0.0.1/admin for its WiFi vending-machine activation workflow.
Separate ISP/WAN performance from radio, client and mesh limitations.
Find the broken layer from the server itself to the public internet.
Restore WAN service methodically after configuration was erased.
Explain why guest isolation intentionally blocks infrastructure and how an authorized admin should manage the router.
Restore local-LAN access when a VPN changes routes, DNS or firewall policy.
Understand local HTTPS certificate warnings without teaching users to ignore certificate problems everywhere.
Diagnose a TCP refusal separately from DNS, password and internet-access problems.
Reach a private gateway when the browser treats an IP/hostname as a search query or rewrites the connection.
