There are internet bots that search for ASIC miners that have not had their factory password changed and then change the internal settings. A factory reset to the device while on a LAN not connected to the internet and then a password change might do the trick.
ok thanks
i will try but how can i connect the antminer to the lan but not to the internet ??
i also realized i need a pc..... cant do it with the mac
So home internet router. Unplug the incoming internet cable to the router but leave the cable hooked to the ASIC. If you have a wireless router you can still access the Asics web interface with the phone hooked to the wifi.
