Re: RB951G-2HnD,wireless problem.

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.

Re: RB951G-2HnD,wireless problem.

This log entry is showing that is it disconnecting all the wireless clients, as maybe you enabled some monitoring tool, for example, scan?

Well,sounds reasonable,thanks. :D

Re: RB951G-2HnD,wireless problem.

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...

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

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.

Re: Can you get 300Mbps WiFi connection to your router?

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?

Re: RB951G-2HnD cannot get 300mhz

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?

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)?
