So i bought a 2015 gmc duramax. It was already deleted and tuned and had ez lynk and all that. Ez lynk has been fine. I have been able to get on it with my phone no problems. A few days ago, out of nowhere, my wifi changed for it. Not just the password. I mean the name of it and everything. No idea what the password could be. Any suggestions on what i could do. I have had the truck maybe 2 months.
