Hi, I allready tried with no kernel parameters set. I found those options
used in other Toshiba notebooks.

Following your request I tried again. I removed the post-down option and
those kernel parameters: the Realtek controller disappeared again.

The WIFI controller is PCI Express as the RTL8105e and it works flawlessly
:-)
