            Bug ID: 197121
           Summary: "run" card (RT3071) very slow connection (USB)
           Product: Base System
           Version: 11.0-CURRENT
          Hardware: amd64
                OS: Any
            Status: New
          Severity: Affects Many People
          Priority: ---
         Component: wireless
          Assignee: freebsd-wireless@FreeBSD.org
          Reporter: miguelmcl...@gmail.com

I've mailed before about this but
(https://lists.freebsd.org/pipermail/freebsd-wireless/2014-November/005251.html)
but got no more feedback


Both 11 and 10.1 give very close results and not much better than this:
 speedtest
Retrieving speedtest.net configuration...
Retrieving speedtest.net server list...
Testing from Vodafone Portugal (95.136.125.232)...
Selecting best server based on ping...

Is that "DS/1Mps" maybe the cause of the problem?

I tried seting "ucastrate 54 mcastrate 54 mgmtrate 54" It changes too:  
media: IEEE 802.11 Wireless Ethernet OFDM/54Mbps mode 11g

But performance is not affected at all, so I guess not, but still I tough I
should mention it!

NOTE, I'm aware USB run drivers only support 11g and not N but still extremely
bad performance, at a very close proximity to the router.


If any more info is needed for debbuging please do ask.

Thans
