Alright y’all…I’m about to blow your minds with this one!! It’s 5G interference!! You know that thing you heard about in the news and the new 5G cell towers near airports interfering with aircraft radio altimeters…it’s the same thing. MANY of you have stated that the Wi-Fi interference usually happens in the SAME places around town…next time look around…I bet you there will be a cell tower near by, then look at your phone…bet you’ll have full bars of 5G!! I have a 2021 Silverado and the exact same thing happens to me. If I wasn’t in aviation I wouldn’t have figured it out. Nothing will fix it until GM updates the Wi-Fi equipment in the vehicles.
