HERE ARE SOME SIMPLE SOLUTIONS TO TRYTo top
Try turning off the Wi-Fi on your device then re-enabling it. Alternatively, unplugging the modem and plugging it back in 30 seconds later. If that doesn’t help, or the problem re-occurs, consider deleting your current network from the list of saved networks on your device, then re-connecting again. Last, should this all fail, try rebooting your device.
If there are still problems please try contacting your ISP. It might be an issue with your service rather than your device.
IF THE PROBLEM STILL PERSISTS TRY REINSTALLING THE NETWORK DRIVER.To top
