RT-N66U - 5Ghz N will not work with new devices (iPad, MacBook, Android)

[striders]

I have the RT-N66U for about a year now, setup with 2.4Ghz (G only) and 5Ghz (N only) channel. Work just fine.

Now I got newer devices, none of them work with the 5Ghz N-only channel, only 2.4 Ghz. These are:

1). MacBook Air 13" with OSX 10.9.2 - got "Connection Timed Out".
Tested with 3 of the same laptops and same problem

2). Galaxy S4 Active and Galaxy Note 3 with JellyBean 4.1.2 - got "Authentication Error occured" - changed the Note 3 already.

All my old devices work though:

1). 2011 MacBook Air with OSX 10.9.2

2). 2008 MacBook Pro with OSX 10.9.2

3). 2007 Dell XPS 13 with Linksys PCMCIA card

I tried upgrading to the latest firmware, downgrading to firmware 3.0.0.4.374.720 and to no avail. I am at loss on why it won't work. Anybody have any insight to this?

My 5Ghz settings are:

• Wireless Mode: N Only
• Channel bandwidth: 40 Mhz
• Control Channel: 153
• Authentication Method: WPA2-Personal
• WPA Encryption: AES
• Mac Filtering: enabled
• Multicast Rate: Auto
• Preamble: Auto
• RTS THreshold: 2347
• DTIM Interval: 3
• Beacon Interval: 100
• Enable TX Bursting: Yes
• Enable WMM APSD: Yes
• TX Power adjustment: 80mW (default value)

Try going to asus website for n66u and download the latest firmware. Flash the firmware.

Then reset router to factory defaults. Then remove your old wireless profiles (forget this network).

.979 isn't the latest firmware. You have to get it from asus website.

My ipad works fine. I use mostly default settings except I use "20 MHz" width for 2.4 ghz.

I did upgrade to the latest one, straight from ASUS website. (PS: my signature is wrong - I don't use 979).

Also, I have no problem with 2.4Ghz, ONLY 5Ghz N . All these new devices connect just fine on 2.4 Ghz, but errors as shown below on 5Ghz N Only.

I used to use "n only". Now I use auto. Seems to work better.

I guess you may have to remove your old wireless profiles and reconnect.

Tried "Auto", didn't work. Questions:
- What firmware are you using?
- Do you have MacBook and Android phone (1 year old or less)?

Just trying to find out if this is more of the devices chip problems (newer devices) or the router problem, but this is bizarre because I can connect to 5Ghz N network just fine in the office...

I'm using the latest firmware from asus website.

I use windows 8.1 with atheros wireless, iPad mini (Broadcom), and laptop with another/different Broadcom adapter.

When was the last time you reset the router to factory defaults ? When was the last time you removed your old wireless profiles? Have you tried updating your wireless card drivers?

The problem is with the newest MacBook Air, though I am sure it's not a defective laptops since all 3 of them exhibit the same problem. Driver wise, nothing to update, at least for OSX. Same goes for Android - I can't upgrade the driver.

All "wireless profiles" were removed from the MacBook and Android devices. As a matter of fact, I have reset both to factory state (fresh install on MacBook and hard reset on Android devices).

I haven't done any reset to the router since it's been working just fine for a year.... ONLY with NEW DEVICES (MacBook and Android devices) I have problem. Can't be the MacBook and Android devices, since these are multiple devices and from different companies. Also, as I mentioned above, these works fine at my work office network with 5Ghz network.

I am going to do a reset on the router.

To completely clean the router of any settings or back to go back factory default settings....(note this will erase all your settings and start anew)

1. http://192.168.1.1/Main_AdmStatus_Content.asp

or telenet into your router

2. Type in

mtd-erase -d nvram

reboot

Done!

Thanks for he help guys! I did the reset and now the 5Ghz N connection is stable to all the new devices.

I did notice that if I enabled MAC filtering, the connection CAN be slow, though at least I am connected. I.e. not "Connection Timed out" or "Authentication Error".

I have a iPad Air and never had a problem on the 5GHz band. And I have used Merlin's and Asus stock firmware.

Do you use:
- Encryption and what kind?
- MAC address filtering?
- 20/40 Mhz?
