Regression AR2413 from 9.1 to 10

All, I am in the process of upgrading my NanoBSD-ALIX kit from 802.11g to 802.11n. First step is to move from 9.1-PRERELEASE (100% stable) to 10-CURRENT with current hardware (AR2413). And alas, I am experiencing stalling wifi on all my clients: after about 30-60 seconds of being online, the clien

Re: Regression AR2413 from 9.1 to 10

Hi Adrian, I am unable to build any svn sources from around March and April due to some yacc/parse.y failure that I cannot fix within the time I have. Can I simply restore an older version of sys/modules/ath and sys/dev/ath into an up-to-date /usr/src? Thanks Sven On Sun, Sep 23, 2012 at 10:14

Re: Regression AR2413 from 9.1 to 10

So far, so good! FreeBSD 10.0-CURRENT #0 r240893 running since this morning without glitches on my trusty AR2413. Great work! On Tue, Sep 25, 2012 at 5:37 AM, Adrian Chadd wrote: > Please try the latest -HEAD and report back. ___ freebsd-wireless@freebs

AR9160 3x3 but only getting 2x2?

Hi there, I'm running FreeBSD 10-CURRENT r240893 on ALIX, just replaced my old 802.11g by a DNMA-83 3x3 802.11 card, works great, but ath only finds 2x2 instead of 3x3? dmesg with 1 antenna (which is what I'm testing now, I already really like MCS 7 over 11g): ath0: mem 0xe008-0xe008 ir

Ath 40MHz on 2.4GHz?

Does ath on CURRENT support 40Mhz channels on 2.4GHz for 802.11n? If yes, how do I enable it? I now have in rc.conf: wlans_ath0="wlan0" create_args_wlan0="wlanmode hostap" ifconfig_wlan0="inet 192.168.2.1 netmask 255.255.255.0 country NL mode 11ng channel 6:ht/40-" ifconfig -v wlan0 shows (among

Spectrum analysis?

Is there a way to do a spectrum analysis for the wifi band with ath on CURRENT? I would like to understand which channels give me the best signal/noise ratio (my baby monitor completely blows our wifi away) above and beyond other 802.11 activities. Does not need to be fast. Mikrotik has something l

ath performance degradation between Oct-12 and now?

I have just upgraded my ALIX router (with an Atheros 9160) from FreeBSD-HEAD r241243 (Oct 6, 2012) to r247155 (today) and I am noticing slightly lower throughput rates. With iperf, sitting 1 meter from the router, I consistently get 79-81 Mbits/sec TCP with r241243. This "drops" to 74-76 in r24715

From AR9160 to AR9340/AR9582

Does anyone know enough about the various Atheros devices to tell me the differences between various radios, output power, sensitivity and expected range? For various reasons, I am thinking of replacing my present FreeBSD ALIX router by a COTS OpenWRT router such as the TP-Link WDR3600. Current h

AR9160 on HEAD - unstable?

Ever since I upgraded my NanoBSD from May to October HEAD, I seem to be getting disconnects on my WLAN. It is most visible when I'm on a Skype video call on my MacBook Air, signal strength fine (MCS 15), but the MBA just loses the connection and I need to switch its wireless off and on again. Someh

Re: AR9160 on HEAD - unstable?

Well, my original hypothesis was wrong: HEAD r250200 (around 3 May 2013) fully lost its wifi on me this morning. My iPhone was on during the night, which generated a long list of "stuck beacon" messages. The iPhone could not get a connection and neither could any other stations. A warm reboot did n

Re: AR9160 on HEAD - unstable?

OK will ignore the stuck beacon stuff :-). Warm reboot is indeed typing "reboot". That did not resolve this morning's matter. Actually, after I unplugged the ALIX for a couple of seconds, it came back up... same problem! Second time, I unplugged it for 30 seconds... problem solved...! Hardware issu

Re: Should I choose 10 or 11 of best WiFi AP expirience? :)

Hi Adrian, Thanks for all your hard work. To add to Lev's: what is the state of wifi in 10-RELEASE? Have significant improvements been made to CURRENT since then, or would 10-RELEASE be a good upgrade from an "oldish" CURRENT? It would be great to help people make their own decision based on some
