RT-AC66U - much problems with iPhone 4 + 4s

[Kaschi68]

Hello,
sorry for my bad english .

I have problems with 2,4Ghz on my iPhones. DL/UL is very slow. Connecting is frequently broken.

My firmware is Merlin 3.0.0.4.220.18b (is the best of my test)

See my Settings on Pictures.

Thanks for helping,
Kaschi

Instead of "Auto" for the channel try to manually set it. Use a wifi analyzer tool like InSSIDer for Windows or Wifi Analyzer for Android (I'm sure similar tools also exist for iOS) to determine which channel is the least used in your neighborhood.

Also I recommend you set the output power back to the default of 80 mw at least until you troubleshoot your stability problem.. If you go too high, it can cause signal distortion, which could also lead to stability issues.

Also note that iOS 6 has various issues related to wifi, so this could be another reason for your problems if you upgraded. Another "revolution" from Apple.

Settings on the 2.4 GHz

As RMerlin answered install inssider on one of your pc:s and see the traffic and signal strength of your own 2.4 GHz band and if you have a lot of other wireless networks in your neighborhood.
You can try and test if Kanalbandbreite : 40 MHz , Kanal : a set channel from the inssider , Auth M. : WPA2-Auto-Personal and WPA Encr. :TKIP+AES.
I have these settings on my own 2.4 GHZ band and have no problem to connect with Ipod and Android smartphone.

Thanks for your fast answer

Switch to 80mW is very good

When i try 40Mhz, the Channel switch automatically from 1 to 2 Channel and 2 to 1 Channel to see in inSSIDer (ch11+ch7 -->ch11-->ch11+ch7........).
Is this normally ?

I have no networks from neighborhood found. But i have very much radio controlled equipment....

Is my beacon interval have i set to 80, is this ok ? I feel this is better

What is better for WLan, QoS on or off ?

Yes , it is normal with 2 channels in InSSIDer.
Perhaps you should leave the beacon interval set to the default 100 and
change Preamble Type to Short.
Regarding QoS you will have to try both off and on to see if you see
any improvement regarding response time.

 

[RMerlin]

Don't turn QoS on unless you absolutely need it, as it comes at a cost in term of raw throughput.

Hello RMerlin and mikeg,

thank you for help

This are my actually Settings and the Connection is very great !!

QoS = off







Have a nice Day,
