You have also been told about posting to a relevant thread! This thread is about dialup
access. You are asking about wireless. See the difference?
You need to find out what kind of wireless card you have - no, it's not "802.11 PCI".
Enter "lspci" into a terminal - look for the line that mentions "wireless" or "wifi" stuff. It will have the chipset manufacturer name and a number in it. Copy it to a new post in a thread which also talks about the same chipset - but read the thread first
: chances are it solves the issue for you.
If you want to refer to "somebody" - link to their comment. That way, respondants can go look for themselves.
If someone suggests something you know nothing about - put the name into a google search bar and press enter. You'll soon know more than you need.
