Time:11-02

In a piece of external SSD installed ubuntu20.04, start loading system after the update software when wifi is normal, the next day wifi connection options disappear once again into the system, search the wifi in the Settings show can not find the network adapter, find some tutorials, such as in software and update download updates then find a network card driver in additional drivers, tried invalid, additional driver only graphics driver, if there is any technical Daniel can help us have a look at what is this? Wifi was when the spirit is ineffective, really make people collapse,
