Yo! As the title says I have in my possession an Asus RT-N56U Dual Band Wireless Router. A friend gave it to me, since the 2.4 GHz Band stopped working. He says that the Antenna could have melted because he tried resetting the device, upgrading its firmware, and verifying that the Router's page had the spectrum enabled.
I also tried those steps to verify it to no avail.
Any suggestions?
Thanks!
1st, check that the 2.4 antennae is on and that the 2.4 SSID is broadcast in the wireless setup page of the router.
If that all good, you could try to update the firmware
Networking - RT-N56U
Manuals are under Manuals & Document
Firmware is under Drivers and Tools (skip the beta version and grab the nexy one - Version 3.0.0.4.374.979
Might as well have a look at the FAWs too - there might be a solution there.
I've seen many similar complaints about this particular router and 2.4Ghz signal problems.

From what I have read about this router it's required to set the 2.4Ghz channel manually and use only channels 1-11. The Auto channel settings can cause problems as it tends to choose channels past 11 which devices in the US can't connect to. It's best to choose a single channel that has the cleanest signal in your area.
Also check the channel range, make sure it's set to channels 1-11 and not 1-13 "for US".
You also must use a different SSID for both frequency's.
Also make sure the 2.4Ghz radio is turned on via the directions below.
1. Please launch browser and go to the setting page of router.
The default IP address of ASUS router is 192.168.1.1.
The default username and password are “admin”.
2. Disable the signal of 2.4GHz in setting page.
(1) Click “Network Map”
(2) Click the icon—“ASUS RT-N56U”
(3) Click “2.4GHz”
(4) Click “On” in item—“Wireless radio”
(5) Click button—“Apply” and wait system update completely
I have the sibling RT-N53 router (no USB port) and the throughput was lousy until the most recent firmware, FW_RT_N53_3004_374-311 (note, this is for the RT-N53 router), was applied.
My speed was 5.5 Mbps and now it's 39-72 Mbps (long distance wireless + lots of noise around me). A lot of the speed issue has to due with the BCM BT/802.11 minicard in my laptop. I recently bought a tablet which gets a consistent 150 Mbps.
You might have to enter Rescue mode before applying a firmware update since the condition of the device is uncertain. see page 45 in http://dlcdnet.asus.com/pub/ASUS/wir...al_English.pdf
You might need the following utilities
>> I've never used the firmware utility, I always hardwire a connection to the router and use the Web GUI on the router
ASUS RT-N56U Firmware Restoration version 1.9.0.2
Utility supports MFP (Multi-function Peripheral, MFP or All-in-One Printer) version 1.0.3.3
ASUS RT-N56U Device Discovery version 1.4.6.4

.
Then follow the firmware update instructions
Thanks for the replies! Sorry for not answering, I've been busy in the previous months XD. Will see how it does!
I had same problem with 2.4GHz stopping working. In my case it looks like something had enabled WPS security again. Disabling WPS security in the "Wireless" section allowed my old devices on 2.4GHz to work again.
