Problem, after the install all works perfectly but the wireless, and installing new packages without a net is not so comfortable.
You have to search on the net for the name of the packages you need, download them and ALL their dependency put them on a USB stick and then hope that this work and resolve your problem. Naturally the first try (new kernel module for the wireless card, a rt61 + his firmware) did not solve the problem.

An RSS document (which is called a “feed”, “web feed”, or “channel”) includes full or summarized text, plus metadata such as publishing dates and authorship.
