It's zero with your patch; I do not have values from before at hand right now, but can provide them later on, should they be of interest. Cheers Marcus signature.asc Description: PGP signature

It seems to come at the price of relatively bad performance, though. After r302035 from avos@, I can't get more than 500 kbit/s downstream from anywhere. I don't think that this is a regression - that was already noted in PR 203105: -Speed seems limited to 16Mbps rate (around 120 kbps on downstream), even though the ifconfig summary show 802.11g/56mbps.

Heh, there isn't any 11n support in rtwn (and won't be until I unify rtwn and urtwn post-11.) I'll go find the rtwn NIC and see if I can figure out what's going on. -a On 27 June 2016 at 10:21, Otacílio wrote: > Em 27/06/2016 14:06, Marcus von Appen escreveu: >> >> Hi, >> >> thanks to previous efforts, the rtwn(0) connection for my RTL8188CE >> wireless card is far more stable.

Hi, thanks to previous efforts, the rtwn(0) connection for my RTL8188CE wireless card is far more stable. It seems to come at the price of relatively bad performance, though. After r302035 from avos@, I can't get more than 500 kbit/s downstream from anywhere. Let me know, what information is necessary to isolate and correct that issue. I'll gladly test it. :-) Cheers Marcus signature.asc Description: PGP signature
