Hi,
what is the RS network performance ? (netperf, iperf - TCP) I seem to have trouble going over 25mbit on both ethernet and wireless with the stock opewrt. Is DD-WRT doin any better ?

Try it, the version is 24 h free as a trial-version. _________________ 300 Routerboards, 250 Nanostations, 150 Buffalo/Linksys with DD-WRT.

I it is not that easy there is no shell access in the trial version, there is no netperf or iperf installed. So no, I can not do a comparable test myself. I would if I could ...

testing with iperf is a bad idea. iperf takes too much cpu load. so connect a laptop behind and use the laptop as test client. running measurement tools on the device itself will always give lower results since the available cpu power is a big point in high speed links _________________ "So you tried to use the computer and it started smoking?

Obviously you either don't know the truth or don't want to disclose it. Either way you are wrong, since there was a SW issue which is now fixed on OpenWRT. The figures are much better even when running netperf/iperf directly on the tested board...
interesting...r u having "any" issues w/the DCMA-82 radio?...i'm just wondering if there is any correlation between the 3rd ehternet port not working & the DCMA-82 radio since i'm having some issues that i think is related to the DCMA-82 radio...i have the DCMA-82 radio in slot1 on the routerstation and configured as "client bridge" and the radio cycles between connect/reconnect to AP continuously....i've got a replacement radio on the way...i'll test ethernet port3 w/the DCMA-82 today....cheers...;-} _________________ WRT54G-TM (12/17/08) mega-11218

i dont think so. i'm working together with the openwrt guys. i just told the best way to get realistic results and you are punishing me for this. nice guy _________________ "So you tried to use the computer and it started smoking?

the RS has some strange hw problems like some bad soldered ethernet switches, silicon bugs and other things.
i think we will have some more problems with this bad hw in the future until it will be fixed in higher rev. so dont expect to much out of it.
i will wait a few months before i'll purchase my 1st test sample _________________ Forum Guidelines...How to get help

the dma cpu hw bug will very unlikelly be fixed. i contributed a workaround for the hal to openwrt as well, but atheros told me that this will not be fixed since it only affects ar5006 chipsets, but not the newer 802.11n ar5008 and ar9xxx chipsets. i havent tested the ar7200 yet, but it has only a minipci express slot, so its definitly not comparable _________________ "So you tried to use the computer and it started smoking?

but as additionap performance information. i have a older litestation x running with a single mini pci card in 802.11a turbo mode which brings here around 60 mbit throughput. this measurements can also be taken for the routerstation. its just a question of the right wifi configuration. for point to point links its always good to enable fast framing for example _________________ "So you tried to use the computer and it started smoking?
