Hi,
There might be three possibilities -
1. You should use an anternative driver.
2. You have a power saver feature enabled.
3. There is a conflicting driver being loaded.
Ensure that the hardwired cable, if any, is disconnected and a fresh terminal is opened. You need to run

If it's integrated in the computer, run:
Also run:
ip a
and:
ip l
and
lshw -C network
and:
lsmod
Hope this will help you.
