Wifi driver installation

[ffoody]

Hello, I'm new to this forum but have used Linux for quite a few years and usually manage to sort out problems by searching here or elsewhere. However, I'm trying to install a Realtek USB wireless adaptor as I'm switching broadband providers and will connect to the new hub wirelessly. I've been able to run the install.sh file ok in Terminal but get error messages so the installation is incomplete. The software is on a CD and so I copied the Linux folder to my Desktop to run it using sh ./install.sh The tar ball is unpacked OK but then there's a sequence of errors. My system is Linux Mint 18.1 Serena. I can't make it run from the disk. Many thanks for any help and apologies if it's just me being thick! This is the section from Terminal that shows the errors:

Please post results for

lsusb

I think source code can be found at github that will compile, just want to make sure your device is covered

Here's the result of running lsusb

[JeremyB]

Was the USB wifi plugged in when you ran the command?

[ffoody]

Hi Jeremy. Thanks for this help. No I'd not plugged in the adaptor as all the instructions I've seen say that the driver should be loaded first then plug in the adaptor.

[JeremyB]

Plug it in and run the lsusb[/] command and post results

[ffoody]

Hi Jeremy

Plugged it in and ran lsusb again - results:

Going to be away for a few days and no access to this pc. Look forward to seeing your comments next Monday or Tuesday. Thanks for what you've done so far.
