SOLVED - Newbie - Help connecting wifi USB

Post by dobie17 » Mon Feb 27, 2017 4:47 pm

First time poster. I just installed Linux Cinnamon yesterday. Extremely new to Linux but excited about what I see. Computer doesn't have access to LAN so I bought a wifi USB...

Rosewill RNX-N180UBEv2 (N300 wireless USB adapter)

My research indicated it will work on Linux, but the included CD only has windows drivers. So I am stuck.

My system is a full Linux install (from CD) with these details:

Linux Mint 18.1 Cinnamon 64-bit
Version 3.2.6
Kernel 4.4.0-53-generic
AMD Phenom II X3 705e Processor x 3
Graphics card NVIDIA G92 [GeForce 800 GT]

I do have a wifi laptop next to the computer if I need to download a driver and transfer (via stick USB).

I tried reading other threads but they got deep into other system details and way over my head.

Help?

OK. I moved the computer to access a LAN cable. Then I found a driver for the USB WiFi and downloaded to the Linux machine.

It is in a zipped file in my downloads folder.

I don't know enough about Linux to install the driver now.

Can someone walk me thru how to install the driver?

a. Please generate an overview of your system like this:
- Launch a terminal window (this is how to launch a terminal window);
- make the terminal window full screen, to avoid chopped lines;
- copy/paste this command into the terminal:

Code: Select all

inxi -Fxz
(if you type: the letter F is a capital letter)

Press Enter.

Copy/paste the output in your next message.

b. Do the same with the following three commands:

Code: Select all

rfkill list all
and:

Code: Select all

inxi -Nn
and:

Code: Select all

iwconfig

Was all this with the USB Wifi adapter plugged in? If not, repeat the above with the adapter plugged in.

If it was (and still is) plugged in, what does this command give as output:

If it works (which I think it will), do not install any newer kernels and make sure you select the most cautious update policy (like it says at the end of the how-to).

It downloaded and I restarted, but I don't think it worked. DO I have to set up a new wireless connection?

Did you double-click the downloaded driver package to install it, before you rebooted?

If so, repeat the commands that I requested in my first message (obviously with the adapter plugged in), and post the outputs.

I apologize for my ignorance. I did install before I re-booted. SO I unplugged the dongle and re-plugged it in. Then the computer recognized it and offered me the option to connect via Wi-fi.

So yes it did work! I cannot thank you enough! I'm excited about Linux and I'm trying to learn but not having internet was making that difficult.

Thank you again!

Not so fast. I had to move the ocmputer to get to the LAN cable. Now that the Wifi is working, I moved the computer back to its "home" position, planning on using the wifi. So I turned the computer on and it did not recognize something because no wifi connection was available. I had to unplug the dongle and then plug it back in.

Is there some setting I need to tweak so that it will always scan and find the dongle at startup?

A bit weird, that....

You might try if it helps when you install the latest kernel from the 4.4 series (-64):
Update Manager - panel: View - Linux kernels

After the installation of -64, reboot your computer.

Installing a newer kernel might very well disable your wifi again, so keep the downloaded driver package at hand. You might need it to re-install the driver.

Yes, weird is what I thought as well. I'll try the kernel update and see what happens.

Thanks again.

Hi Pjotr,
which driver must install for 0bda:818b Realtek Semiconductor Corp. I try with RTL8812AU but doesn't work.
Thank you
