Lenovo a820t ink weather can't be updated under wireless network.

Hello, thank you for choosing Lenovo products.

I'm sorry for the inconvenience.

If the weather of the equipment cannot be updated, it is recommended that you try to confirm and operate the following:

1. I suggest you check whether the network you are using is abnormal (wifi connection is abnormal, please refer to/Lenovo/WSI/Station/ServiceStation/default.aspx? MIDH queries the nearest site. The business hours of maintenance stations are generally from 9: 00- 18: 00 from Monday to Sunday, except holidays, and local stations will adjust slightly according to their own operations. I suggest you call for detailed consultation before you go. Please refer to it.

I hope the above reply will help you, thank you for your support to Lenovo, and wish you a happy life.
