I have tried two different USB wifi adapters, but cannot get connected to my Time Warner Cable wifi. I am a completely new user and have a used 2011 Dell Optiplex 790. I did an install on my hard disk, and removed Windows. Mint does run on the hard disk. I plan to hard wire to my router in the next day or so, since the machine was originally connected via a LAN. I am guessing there is no wifi capability in addition to that; hence my attempt to use USB wifi. I am not afraid to go into the terminal; but I really don't know what to do once I get there. Any help would be appreciated.

LesBarrett,

Welcome to LQ.

Surely the simplest solution is to connect your router and PC using an ethernet cable?

If you wish to use a wifi adapter instead, try this:

Yes, I will use the ethernet cable; but I do want to move the computer out of my basement. I ordered the item that was mentioned in your link. I hope it works as advertised.

LesBarrett,

It does.

Do bear in mind that if there is a long distance between the router and the PC, plus thick walls, then your wifi signal is going to be reduced, or in an extreme case, non-existent.

Install inxi - run it from a terminal as follows and post the output.This will show us what hardware and associated drivers you have.

The N-150 CD did not run; the dongle had no effect; the instructions only mentioned Windows. This solution is not as mentioned above.

The original advice I got on this thread was good. I did not understand and had some difficulty. Everything worked out. Hopefully I did not mislead or offend anyone.

LesBarrett,

The CD is for Windows use only. It has no effect on a Linux system.

I can assure you that the D-Link N150 USB wifi adapter works perfectly in Ubuntu 16.04 MATE, Linux Mint 18 MATE and MX-16 to name just a few.

In Linux Mint there is a network icon in the bottom right (between software updates icon and the speaker icon).

Click on that and then select the name of your wifi (SSID).

Enter your wifi password and press Enter to authenticate it.

I have just tried the D-Link N150 USB wifi adapter again in my desktop PC (after removing my ethernet cable) and my SSID is displayed.

After authentication the wifi connects without any problem.

beachboy2,

Thanks again for your help. I followed your procedure; and it indeed worked. I think disconnecting my ethernet hard wire did the trick. For others with this problem, I can verify that the N 150 works on a 2011 Dell Optiplex 790 with a core i7 processor and 4 G of RAM running Mint 18 Cinnamon works. By the way, I also installed an Uhuru wireless keyboard and mouse combo with a USB dongle. It did not work initially; but after I got the wireless working and downloaded the recommended packages with Synaptic Package Manager, the computer recognized the keyboard and mouse.

LesBarrett,

I am glad that you have your wifi working at last.

Alternatively, add a second comment which negates the first one.

Done. Let me know if you have any other problems with my post.

Thanks.
