SB5100 and 51001 Mexico

Hello guys.

New here...

So, just wanted to ask for some help.
Down here in Mexico we used to get online just by changing MACs and disabling BPI.

Using MACs from different nodes and having BPI disabled was enough the get your SB5xxx up and running.

It's been a week or so, since these modems stopped working. Everything looks normal. Modem's lights are all on, however, the icon at the bottom right corner of the desktop shows that yellow triangle and when you try to go to any website, it shows this error: DNS PROBE FINISHED NO INTERNET

Anyway, I hope someone helps us out.

Thanks.
