Description miguelmclara 2015-01-27 05:54:38 UTC

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)...

Also:

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.

I also have this problem, although I am using rt3072.  I emailed the list and am stuck to debug this further.  In my case, I can't even bring up the interface without a crash and instant reboot.

There were others in the pfsense forum having this problem with rt3072 too.

Please make sure that you have 
options USB_DEBUG
in your kernel config file; otherwise run(4) causing kernel panic on device attachment

Any update/feedback on this?

Not having 11n support is sad, but I could live with it if 11g would at least get reasonable speeds!

I wonder if other using "run" but different cards see the same issue?

Upload speed 1.9MB/s [2] with 11g [1] on RT5572 [3] and openWRT reported MCS0 [4] seems reasonable to me.
