Checking for Upates - wi-fi drivers and Networking Software

[anonprivate]

My current version of kubuntu connects to the router via wi-fi without a problem.

Recently, I created a LiveDVD for version 16 (both kubuntu and ubuntu (gnome)), I noticed that the wi-fi connection repeatedly drops.

It occurs to me that my drivers and networking software may not be up to date.

Can I check the wi-fi drivers and networking software? It would be important to ensure a roll-back procedure in case the latest softwares caused a problem with my current, and, working, edition of kubuntu.

Thanks

A LiveDVD cannot be updated. After it is installed the repositories will be accessible for updates. Make a note now of the wifi driver name & and release number so you can install it after you install that LiveDVD on some hardware.

Thank you.

Under kubuntu 14.04 I ran lshw and found:

 *-network
              description: Wireless interface
              product: RT2561/RT61 802.11g PCI
              vendor: Ralink corp.

              resources: irq:18 memory:dcee8000-dceeffff

Is the wi-fi driver name and release number:

Driver name: RT2561/RT61 802.11g PCI

release number: 00

If so, how would this driver be installed after an OS installation?

sudo modprobe rt61pci nohwcrypt=1

If that doesn't allow you to use ModemManager to c onfigure your wireless than consult this more elaborate method.
