Inew V8 Wifi problem

[rigzrk]

I assume you've reset the router, yes? And have you tried a different WiFi router?

If "Yes" and "Yes", then you may need to restore NVRAM. The hack may have modified some protected part of the phone. But it's just a far out guess.

I cant reset router because I don't own him. I am living in the apartment with one family, (I studying away from home) and we share internet. So I cant do that. I restore new NVRAM, but same problem. I need change MAC address on phone, because router block my MAC address of phone, and I cant enter in router setting (gateway) because of username and password.

So yea, I am in big shit now. Just searching how to change MAC address on phone.

Do you have data over cellular working? Does it work after you disconnect and reconnect the cell?

Have you deleted all access points and reconnected?

Was the backup from a time that everything worked perfectly on the device (before any modifications), including wifi, on the exact same router? Does the wifi router connect other devices without a problem?

Yea, that internet works fine. No, doesn't work after disconnect and reconnect the cell.
Yea, backup was on same wifi router. I cant change router, look up post before what I write about router. Other device work normally like PC, laptop, phone. Just my phone cant connect to wifi.
