I'm new to Linux, using Deepin 15.4.1. Issues is as title above.

Hope there are someone can help.

Here is my system network config info:

Create a /etc/modprobe.d/iwlwifi.conf with the following options:

options iwlwifi 11n_disable=8
options iwlwifi bt_coex_active=0
options iwlwifi swcrypto=1

It will enable antenna aggregation ,disable Bluetooth coexistence and enable software encryption.
