[Solved] iwconfig no wireless extensions found
« on: July 27, 2013, 09:48:18 AM »
iwconfig gives the following output

dummy0    no wireless extensions.
eth0      no wireless extensions
and lspci -vv gives this for my wireless

I believe it is not the best of wireless "cards" on an ACER laptop TravelMate 292LCi
Can anyone help with the wifi setup ethernet connection is fine

Did you install firmware-ipw2200.tcz ?

However I think I installed everything else. Which of these would you recommend, use or need
  • wireless_tools
  • wpa_gui
  • wpa_supplicant
  • iw
I have the firmware extension before" wireless-3.0.21-tinycore.tcz" in the onbootlist and that makes wpa_gui see other devices now

Thank you for that vital piece of info. The forum is great for solving problems.

If you install the "wifi" extension, it will install what is required (apart from the firmware) in order for wireless to work in most circumstances.

Check your function keys and make sure you have wireless turned on.

Thanks for ur reply. This acer aspire v5 571p has no wifi switch, only fn+f3... Tc stable with wifi ext. works when win8 isnt on the harddrive. If I format and install tc it works as is, Ive heard w/ win8 it can block the wifi somehow... however, i downloaded the tc 5.0rc1 and its wifi works w/ win8 installed,so yeah everyone try tc 5.0 rc
