RT-N66U: Wireless Network Mode of 2.4 G and 5G can not BOTH set to N only ?

[WilliamY]

Hi, All

I'm using RT-N66U with Tomato Shibby build, Having the problem that my Nexus 5 and new Mac Pro Labtop can NOT connect to my 5G wireless, but both working fine with 2.4G, and just found that somehow BOTH Wireless Network Mode set to N only, Just wondering whether thats the cause or not?

Thanks,

William

As far as I can find both the Nexus 5 and Mac Pro Labtop seems to support 802.11n and both are dual band (2.4 GHz and 5 GHz).
It may be that with your Tomato Shibby configuration the router uses a channel that is officially beyond the legal range for your area.
Try to set a lower channel manual e.g. 36, 40, 44 or 48 which are allowed in almost all areas and see if that helps.
Otherwise I suggest to set the Wireless Mode back to Auto, which should not hurt performance.
To be more precise:

2.4 GHz:

• Wireless Mode: Auto
• b/g Protection: unchecked
• Channel bandwidth: 20 MHz (better against neighbor disturbance)
• Authentication Method: WPA2-Personal

5 GHz:

• Wireless Mode: Auto
• Channel bandwidth: 20/40 MHz
• Authentication Method: WPA2-Personal

The 5G channel was set to lower, 149, and 40mhz. my Samsung Note 2, iPad and iPod 5th Gen connected to 5G without any issue. But the Nexus 5 and the MacBook Pro just can't connect to it at all. Puzzled me. Changed the channel to 36, 20mhz, still won't work.

Check the SSID on 5 GHz, give it a try with a SSID that ONLY contains alphanumeric characters (Aa to Zz and 0 to 9), NO spaces, NO odd characters like @#$%!&.
Do the Nexus 5 and the MacBook Pro "see" your 5 GHz signal, or not at all?

my SSID doesn't include any weird characters, only letters and numbers, Nexus 5 and MacBook Pro both see my 5G SSID, but just can't connect.

Whats odd thing for MacBook Pro was: It said its connected, but no internet connection, because the IP address and subnet mask it got were totally wrong, like 168.24.xxx.xxx, 255.255.0.0, the correct one should be 192.168.1.xx, and 255.255.255.0, I don't know whats wrong.
