Wireless not working

Dumb question: Is the firmware you reference free ?
If not than Trisquel will refuse to work with your adapter since it does not load any non-free firmware files.

It is really unclear to me what is and is not supported by free software here. There appears to be some chipsets supported without non-free firmware. However there may be some modes of operation that are not supported without the non-free firmware.

The only chipsets I'm sure are free software compatible right now with Trisquel 5.5 are: ar9170 and rtl8187/rtl8187b/rtl8187l.

It looks to me like there may be an upcoming driver which does not depend on any non-free firmware as well for some realtek cards. I actually just sent an email to see if we canget some clarifcation. I'll investigate further if the news seems positive...

We actually need a new G USB chipset... which this may or may not solve depending on if these chipsets are discontinued or not.

If you need to get a replacement card we have some stock left of USB wifi cards with those supported chipsets. We have about a months worth of stock verified for the USB G RTL8187B chipset and I also have found some new old stock. Although I'm still looking into aquiring it and I don't know how much exists.

The ar9170 I'm still working on verifying. Supposedly we can get a small quantity to hold us over for another year until support for a newer chipset becomes available.
