Subject: Realtek RTL8191SU really slow with „N” mode enabled
Date: Sat, 27 Jun 2015 11:16:21 +0200	[thread overview]
Message-ID: <37780383.GGTrC2kAY2@linux-suse.hu> (raw)

Dear list members,

I have a "0bda:8172 Realtek RTL8191SU 802.11n WLAN Adapter” working
- previously with kernel v4.0 staging driver r8712u,
- and now with wireless kernel v4.1 driver rtl8192su (from 
https://github.com/chunkeey/rtl8192su).

My problem is when, by default, the 802.11n mode is enabled, the USB dongle's 
connection speed is only around 1 Mb/s (with both drivers). When I turn it off 
with "options rtl8192su ht_enable=0" in its config file, I get my full internet 
speed, about 30 Mb/s.

I'm asking whether it's a problem in the firmware or somewhere in the driver 
code? If it's the latter case and you're interested in, I would like to help 
debugging the problem and help you to fix this issue.

Thank you very much.

All the best,

Ákos
