    Old laptop freezes after connecting to wifi; ethernet works fine

    Hello,

    I'm having trouble getting the wifi to work on my old Toshiba Satellite laptop (ca 2009). Ehernet works fine, but if I disconnect the cable and the computer connects to wifi, the machine always ends up freezing 1-2 min later. Wifi seems to work ok otherwise, as I am able to browse the internet until everything freezes up and I have to reboot the computer.

    I'm running Lubuntu. Here is the link to my specs:

    Re: Old laptop freezes after connecting to wifi; ethernet works fine

    See Wireless-Info in my signature below and follow the info there to run the script and show us the report you get from it.
    Someone who is more expert than I with wifi will no doubt be able to help you sort this out.

    Re: Old laptop freezes after connecting to wifi; ethernet works fine

    Hi,

    Is this what you're looking for?

    http://paste.ubuntu.com/25469741/

    Sorry if I'm not understanding, but I did check out the Wireless Info page you are referring to before posting yesterday. I installed the updates and then ran the script I believe you are referring to (please see link above in this post). Let me know if you need anything else!

    Thanks again!

    Re: Old laptop freezes after connecting to wifi; ethernet works fine

    I resolved the problem by circumventing it: I got a wireless adapter, in this case a TP-Link Archer T2U AC600 Wireless Dual Band USB Adapter.

    I had to install the driver which I did by following the instructions at the bottom of this page: Modified usb wifi driver for TP_link TL-WDN5200

    I'd like to mention that I got pointed into that direction thanks to Chili 555's answer on this page: TP-Link AC600 driver on Ubuntu 14.04 LTS x64. Very much appreciated thank you.

    I originally posted about the issue on this page and received a few answers which did not solve the problem but were helpful nevertheless:
