Why you don't just reset to default and see if not something wrong with your configuration...?! Setting manual tx power can affect wireless clients btw. Well,I've reference the offical manual,looks like HW.Reties & Disconnect Timeout will affect the "data from unknown device" error.

lfs0a

This log entry is showing that is it disconnecting all the wireless clients, as maybe you enabled some monitoring tool, for example, scan?
16:10:56 wireless,info 44:2A:60:DB:9F:D6@wlan2: disconnected, disabling

Well,sounds reasonable,thanks.

lfs0a

looks like you did some changes to the wireless interface and that triggers the wireless client to disconnect. Wireless client didn't get the message about the disconnection and still tries to communicate with the AP till it realizes it needs to reconnect. 16:10:56 wireless,info 44:2A:60:DB:9F:D6@w...

lfs0a

The Power will affect this?looks like impossible.

I have a RB951G-2HnD,and i setup an ap,the top speed is about 3MB/s when i downloading movies through WIFI from another device,is that normal?The TX/RX rate is about 270Mbps/270Mbps.

ADSL is 2M/512K,ping is unstable and about 5-30ms higher than which when network is idle with these configs. any ideas? mangel: 0 chain=forward action=change-mss new-mss=1440 passthrough=yes tcp-flags=syn protocol=tcp in-interface=all-ppp tcp-mss=1441-65535 1 chain=forward action=change-mss new-mss=...

无加密一样，我现在搞点CCNP关于无线的书看下，一点基础知道都没有呢

lfs0a

所有的频道都换过了，这边好像没有其它的AP

hi,araujoprog
i'm just wondering how about the ping delay between the two aps as the distance is 350km.
below 10ms? stable?

lfs0a

upgrage to ROS V6.1 and firmware 3.08,the newest,the same

and the tx/rx rate in the registration table is lower,now most of time is about 150/160,compare to 300/300 before.

11.jpg 22.jpg 昨晚死活弄不上来，而且昨晚上2点了吧差不多，有时候估计超过2分钟都没有问题这可以想象得到是讯号干扰，那是因为你的讯号值太强了。。。尽量调到-45~-55dbm。。。刚才拿到外面去测试了一下，－50－－60，还是会有 UPDATE:Had changed 5100 to Atheros AR9280,turned the win7 firewall off, it's better,sometimes the "time=" could below 10 for a few minutes. ROS V5.25 firmware 3.04.

信号太强也会干扰的啊?

I am having a RB951g-2HnD now, only get 144Mbps to both of my macbooks (didn't test other devices yet).

Stupid question, but just want to know has anyone got that?

我的WIN7 一开始只有130M，在网卡上设置802.11n channel width for band 2.4的值为auto，可以运行在150M，不过的有网卡好像是5G频段才有300M？

lfs0a

hi,zhangxiao,你的RB951G－2HnD无线在Advanced Mode-Tx Power-Tx Power Mode=card rates 的情况下可以更改发射功率么？我的在V5.25版本只有all rates fixed模式下才可以更改。
all rates fixed的模式会比较好运用。。。
也可以会比较好的控制区域无线干扰。。。

nomis的FAQ里面说最好用card rates模式？为什么card rates模式会改不了发射功率了呢？
我的无线1分钟左右就会有几个包ping的time延迟40－80ms,你有遇到过吗？

hi to all. have a RB951G-2HnD now.the ping delay happend again,about 1 minute,the delay show up once,about one to four packets will delay 40-80ms. and the secend problem:i can't change tx power in the "card rates" mode,only the "all rate fixed" mode works. here are the config: /i...

:D Thanks a lot for you long post. dozens of people saw my post and didn't make a reply,maybe they don't have a rb751 or rb951 device? so the teddy-bear1 connect to ap1-mt through radio,right? the ping test looks good,the delay is small and stable. so my device which had returned purchase is definit...

lfs0a

killersoft,learned a lot from your post,thanks.

lfs0a

Thanks a lot!!!

lfs0a

sorry,HaPe,the device had been returned purchase.
now i just wonder can the rb751 rb951 series get a stable ping (above 100 packets) through radio.
Thanks a lot for your reply,could you make a long ping at your RB751U?
if they can,i'm gonna buy another one

lfs0a

HaPe,i had try 20Mhz,the delay still happens.

lfs0a

Thanks a lot for your reply,HaPe.
I had try 5.24 and 5.25.It's about every 80-100 packets,there will be 2-4 packets have a long delay(about 40-80ms),most of them are <1ms,when i upgrage to 5.25,most of them are =3ms.
Did you make a long test(more than 100 packets)?

Good night!

i bought a RB751U-2HnD,and setup an ap,but when i ping from my laptop to RB751U-2HnD,some packets was delayed about 40-80ms,most of them are <1ms. i returned purchase.After the device been tested,they said it's normal. 1.Is it normal? 2.Does the RB751 RB951 series can get a stable ping(through radio...

djfrancis

can you make a ping test from your laptop to the RB751U-2HnD through radio about 150 packets when the RB751U-2HnD is idle,then post the result here? thanks a lot!!!

lfs0a

thanks a lot,c0d3rSh3ll.
why the time is so unstable?R u downloading?

lfs0a

config RB751U-2HnD as a ap,and then connect with your laptop without cable,make a ping test to the wlan interface,150 packets above,then post the resoult,

thanks a lot!!!

lfs0a

when i upgrade from 5.24 to 5.25,i can not see time<1ms anymore,almost time=3ms
