Description
Hi everyone,
i am using a wndr3700 running r26553. I want to use a sip wireless phone (app on an iphone). When moving around, i get some
drop-outs which i believe come from wlan reception getting worse,
at some point rate control switches to a lower speed, but too
late for a continous stream.
As i do not really need high speed for a phone call, i am trying
to nail down the rate to the lowest applicable rate, which then
should give me more constant voice quality. I think i should go for the lowest rate supported under the N-Standard for not to loose any
N-Goodies (MIMO etc).
While there is no setting in LuCI i tried to manually edit
/etc/config/wireless and add a rate option, a minrate option,
a maxrate option, both under the hardware and the locical
BSSID interface. But it doesn't seem to have any effect.
Running a wireshark and looking at the beacon frames, i was
expecting that only my specified rate is included in the beacons.
Also, the iphone indicated always a connection at varying speeds.
Also, no change was possible with setting iwconfig wlanx rate 24M
for example.
I know about the side-effects of throttling down one station
on a shared medium, and i am willing to accept this. I'd even use a dedicated access-point for that specific wlan.
thanks,
Stephan

I'm pretty sure that rate control is not the issue here (at least not on the AP side). The rate control used in mac80211 reacts very fast even to sudden changes in reliability (e.g. disconnecting antennas), without introducing noticeable packet loss.
