Hi, I recently installed in my raspberry pi Raspbian with hostapd 1.0, I
want to make my own Hotspot, but follow all tutorials, I can only get up to
6 stations connected at the same time.
The next error apper with the #7 client try to connect:
*NL80211_CMD_NEW_STATION result: -105 (No buffer space available)*
How I can resize this and make more clients can connect to my device?
Im using TL-WN722N dongle.
Thanks in advice!

That devices contains an AR9271, which uses the ath9k_htc driver. The
number of stations you can maintain is limited by the device RAM.
Luckily the AR9271 firmware is now GPL [1] so you can hack on this
yourself I'm not quite sure what the upper limit is, but we've raised
it to 16 without seeing any obvious breakage.
Try modifying ATH9K_HTC_MAX_STA in the ath9k_htc driver and
ATH_NODE_MAX [2] in the firmware.

You are probably hitting the firmware limit.
Thanks,
