Network Adaptor not recognised

[paulfiske]

I have a Toshiba Satellite C855-2LH laptop with a Realtek network adaptor (recognised when I type lspci -v) RTL8723AE. However, I have started using Knoppix 7.2 and it doesn't list any wifi connections at all in network manager. Is there an easy fix? I am a novice linux user, but like experimenting!

Greetings, paulfiske.

At least for LiveCD-size Knoppix 7.2, Synaptic says it doesn't include 8723:

Ubuntu users have the same problem, apparently.
The following link indicates it's possible to compile your own driver.
Good luck on that.

An easier solution might be to find a NetGear WG111v2 us adaptor for about $15.

Hope this helps.
