Thank you Ali for your reply email. One can wonder why you continue to develop

opportunity to publish this information in the Linux kernel mailing list or
linuxdrivers.org? or have any contacts who can I turn? itself does not implement

Alexander,

I am not quite sure what you are asking, but let me explain the situation as I understand it.

There is a Linux driver for the RTL8191SU devices. It is in the staging sub-tree and is called r8712u. This driver has been available since kernel 2.6.37. It is stable, and handles the HT rates quite well. The one thing it does not do is work as an AP. It cannot be used with hostapd. The reason is that modern versions of hostapd use the features of mac80211 through the nl80211 interface, but r8712u has its own IEEE802.11 stack and does not implement mac80211.

The ultimate fix will be to rewrite the driver to utilize mac80211, which will be a major undertaking. It is on my TODO list, but it has low priority. Realtek does not plan to do that rewrite, thus it will be up to the community.

I hope this message helps you understand what is happening.

Larry
