modprobe commands don't return any output unless there's a problem .. so just run BOTH commands and tell me if wireless now works

ie. after running BOTH commands in the order given .. now if you click the networkmanager icon by the clock, is your network listed ?

If all of this not working, should I go and buy wifi dongle instead?

If your wireless network is listed and not greyed out, you'll be able to connect into it.  When you left click on your wireless network from the list.  You should be presented with a box asking for your password.  Similar to the image below:


 This is not your user password.  You must enter your WiFi password.  This is usually found on the back of the router your ISP gave you.  Enter this and click on connect.  That should connect you to the internet  ;).
Backup! Backup! Backup! If you're missing any of these -  you ain't Backed Up!
For my system info please L/click HERE.

Okay, what's the output from:
Code: [Select]
iwconfig
and
Code: [Select]
iwlist scan
and
Code: [Select]
rfkill list
and does the box Andy showed you accept your wireless password, or tell you it's incorrect ?

What Andy meant by "this is not your password" is the dialogbox in his pic does NOT expect your Peppermint password, it expects your *wireless* password .. if you do not know your wireless password there is no way to connect.

At this point there's little point in getting a USB wireless card .. the Broadcom one *IS* supported .. firstly we need to figure out if the problem is
a) you don't know the wireless password, or have been entering it wrong
or
b) if the Broadcom adapter is physically broken, or there's a software issue somewhere
or
c) the Broadcom adapter is being blocked for some reason

Well I can see nothing wrong there

So can you answer my other question - "does the box Andy showed you accept your wireless password, or tell you it's incorrect ?"

You need to describe exactly what's happening when you try to connect.

I know that problem all too well, but here it's not Linux related. It's my modem/router (Siemens) in desperate need of a reset. I disconnect the power, wait 5 seconds, connect it again and I'm fine for a week or so.  This started to happen when more and more (wireless) devices started to populate the house. At a certain point in time the router started to develop this problem.
If you like Linux, raise your hand. If you don't, raise your standards.
