What are the reasons for the sudden loss of internet connection in the Haval H6?

Haval H6's internet connectivity loss can be attributed to network failure, unpaid data card bills, nearby interference, or outdated vehicle system. Below are detailed explanations and solutions: Network Failure: If the Haval H6's infotainment system experiences network issues, it could be due to software or hardware problems. Owners can visit a 4S shop or repair shop for professional inspection to resolve the issue more quickly. Unpaid Data Card Bills: The Haval H6's internet connectivity requires payment for data services. If the owner hasn't paid the bill, the network will not be available. Simply paying the network fee will restore internet access. Nearby Interference: Signal blockers or jammers in the vicinity can prevent the Haval H6 from receiving network signals, leading to connectivity issues. Owners only need to drive a certain distance away from the interference zone to regain network access. Outdated Vehicle System: If the vehicle's infotainment system is too old and hasn't been updated for a long time, it may also cause such issues. Updating the Haval H6's infotainment system will resolve the problem.

My Haval H6 also experienced a network disconnection last week. After struggling for a while, I found it was a basic issue: the data package was used up. Now the car's data plan is separate from the phone plan, so you have to check it yourself. If there's no signal bar icon on the dashboard, it might be because the airplane mode in the car's system was accidentally turned on. The most effective solution is the restart trick—hold down the volume knob on the center console for ten seconds to force a reboot. If that doesn’t work, you’ll have to pull the fuse; the F46 behind the glove box in the passenger seat controls the networking module. Steel-framed roofs in open-air parking lots can also block signals—try driving out about 200 meters. Oh, and if the shark fin antenna on the roof is covered with snow, the signal will definitely be dead.

For long-haul drivers, a malfunctioning car network is a real headache. First, check if the indicator light on the connectivity module (the small black box) at the top center of the windshield is blinking. A steady red light means the module has crashed. You can check real-time data usage in the Haval Zhijia APP, and top-ups are also done here. Some batches of vehicles have software bugs—pressing the steering wheel phone button three times can bring up a hidden diagnostic menu. At the 4S shop, they often remove and reinsert the SIM card tray; oxidation on the metal tray can cause poor contact. If you've modified your dashcam to connect to the fuse box, be especially careful not to tamper with the F28 fuse.

Last month, the neighbor's sister also experienced a network disconnection in her H6, which was finally traced back to the in-car WiFi being accidentally turned off by her child. Press the MENU button below the air conditioning panel to enter the system settings, and toggle the in-car WiFi switch back on in the network connection settings. Remember to back up your navigation favorites before resetting the infotainment system to factory settings. You can enter the engineering mode by simultaneously tapping the top-left and bottom-right corners of the screen with two fingers. For cars parked in underground garages for extended periods, be especially cautious as the module may enter a dormant state and appear unresponsive. Drive the car out for 20 minutes to let the sun warm up the roof. Currently, the OTA update packages pushed by Haval exceed 1GB, and the engine must be running to complete the download.
