Provide a IP to ur bluetooth connection PAN (on main pc which has internet) ... like 192.168.0.1Leave the gateway as blank ...Activate PAN from laptop and set it to access PAN of ur desktop ...Once authentication is done then give the IP like 192.168.0.2 and gateway 192.168.0.1 to ur laptop's PAN ...Activate ICS for ur internet in ur desktopDone 🙂So I guess there shouldn't be this "activating ICS" step involved while paring in ubuntu ... right?
