Firmware

• Asuswrt firmware- the original official firmware from Asus, which comes with the router. Current and previous versions can be found here:https://www.asus.com/r…87U/HelpDesk_Download/
  
  
• Custom firmware Asuswrt-Merlin- firmware from R. Merlin, based on the original, while containing bug fixes, current versions of components, performance optimization, additional functions. Current and previous versions can be found here:http://asuswrt.lostrealm.ca/download
  
  
• Custom firmware Asuswrt-HGG- firmware from Hugo Gomes, based on Asuswrt-Merlin. It differs from the previous one in that access to NVRAM is unlocked, some components are added, the maximum power of the wireless transmitter is increased, all wireless channels are unlocked, and the functionality is increased. The latest version of the firmware can be obtained by writing to him by e-mail (in English / Spanish):[email protected]. The guy is kind and helpful. Bug reports are welcome.
  P.S.Due to the fact that Hugo was kidnapped by aliens, it is impossible to rely on him to get the firmware. Latest versions available for download.here. The old version of Quantenna firmware is used in OLDQTN firmware - it is for those who have problems with fresh firmware.
  
  
• DD-WRT firmware- is a 100% alternative firmware (NOTbased on the original). It has its pros and cons compared to the original. Recommended for installation only with the full knowledge of why you really need it. Current and previous versions can be found here:ftp://ftp.dd-wrt.com/betas/
  
  !!!Custom firmware is strongly recommended to flash usingAsus Firmware Restoration Utility. If you were stitching through the web interface, it is strongly recommended to do a reset. You will have to re-enter the settings manually - the configuration files cannot be used, since This may lead to bugs and instability of the firmware.
  

How to use Asus Firmware Restoration Utility

1. First we need to download and install it. Find it here:https://www.asus.com/r…87U/HelpDesk_Download/
   
2. After installation, go to the properties of the network card and manually enter the addresses:IP address 192.168.1.10, Subnet mask 255.255.255.0, main gate 192.168.1.1
   
3. Turn off the router button
   
4. Insert the network cable into the LAN port 2, 3 or 4
   
5. Hold the reset button (next to the power button) for 10 seconds
   
6. Holding the button down, turn on the router
   
7. When the power indicator flashes slowly - the reset button can be released
   
8. Open our utility, select the firmware file and flash
   

All about overclocking

You can overclock the router in two ways:CFE bootloader editingorthrough parameter changes in NVRAM.

First wayUniversal and suitable for any firmware - the main disadvantage of this method is that if you use redundant or incorrect settings to restore the router to a working state, you will have to use a programmer or UART. This principle during overclocking uses the programac87utility- with its help, overclocking is much easier and safer for new users in this business.

Second waywill workNOTon all firmware. Apply only on the following firmware: drain and merlin - version up to 378.53, gomez - all versions. The main advantage lies in the fact that all applied changes can be easily reset with the Reset button. Yes, and fuss less. How it's done:

• Go to the terminal
  
• To get the current values, drive in the following:
  
  nvram get clkfreq
  
  
• To change the current values ​​by, say, "1400,800" we drive the following command:
  
  nvram set clkfreq = 1400,800
  
  
• After we have made all the desired changes in NVRAM, they need to be saved and for their entry into force you need to restart the router:
  
  nvram commit
  reboot
  
  

!!!When accelerating the router, carefully monitor the temperatures. And although the maximum allowable temperature of the processor is 125 degrees, it is strongly recommended not to raise it above 100 degrees.

And can someone share the firmware from Hugo? English is lame for letters, not to mention Spanish. : blush:

Hello!
I suddenly ceased to be visible grid wifi 5G. The settings remained the same and the devices that had previously seen it, now can not see. And, interestingly, when the router is restarted, this grid becomes visible for a split second, and then disappears from the list of networks.
Can anyone come across this problem?

Most likely you have an automatic channel selection on the 5GHz network. Each device has its own WiFi region, which allows them to use a specific set of channels. Try to set the 44th channel to check - if the devices start to see it and connect without problems, then later change it to 157 channel (more performance).

Firmware from Hugo. Periodically, the Internet falls off on the 2.4 grid, on the 5-ke it seems to hold steadily and on LAN too. It is the Internet that falls off, the grid itself shows the full antenna.

You have not unplugged the transmitter power by 100%? Just 100% on this firmware is very much - at 75% the transmitter works THREE times more powerful than at 100% on the drain. Put on 75% and you will use the Internet within 300 meters like me))

P.S.My 2.4 weighs a bunch of devices, including the main laptop. Problems with the Internet is not noticed at all.

I found the power control, it was really the default of 100%. Now reduced to 75%, I will test.

If the default was 100%, then you installed the firmware incorrectly. The default should be 50%.

This happens when I set the channel width to 80 MHz, I have no problems with 40. I didn’t understand the exact patterns, but 80 MGz earned on channel 36, on the 100th channel it didn’t work on anything, and the interfaces still flow to the same. Firmware - the latest release from asus.

As I mentioned earlier, each device has its own regional frequency limits. European devices for the most part with channels 50-144 workNOTwill be Use channel 157 and you will be happy. Yes, 36-48 are universal, but in this router the transmitter power for these channels is limited to 16dBm. On channel 157, you will get maximum performance and coverage.

On the stock firmware, the maximum installed channel is 112: rolleyes:

Hello everyone, I really want to test the firmware from Hugo, but he does not respond. You can ask to reset to the mail: [email protected]
Or post a link. Thank you very much in advance!

Yesterday I bought this device for cloud storage (WD My Cloud) and external HD for 1 Tb, and the top three consumption devices. TP-link 841N dealt with this poorly, or rather in any way. Configured under the network provider in just one click. Further, rummaged in connections via LAN - the cloud was immediately determined. But just in case I set firewood. The moral is this - today I took the router back to the store. : rofl:} -)
Yes, sometimes. Now in more detail.
Out of the box was the current firmware. But I never saw 5 Hz. I read kilometers of traffic from the site of ASUS - to no avail. I saw comments about the firmware (Version 3.0.0.4.378.9529). As if there were no 5 Hz problems on it. And in general, this version is more stable. Decided to install. Used with [/ COLOR] of ASUS Firmware Restoration version 2.0.0.0. All according to the instructions.
As a result, the router no longer started. The food is there, the lights are flashing, it is impossible to exit the settings. IP did not even see.
As mentioned earlier, carried to the replacement store. Tomorrow I will dryuyat copy. If that did not work out. : blush:
I read a little forum here, people recommend leaving either a width of 40 or a channel for 150 to choose. I'll try, very interesting.
And so, I liked the router very much: the management is intuitive, productive (very), though it doesn’t allow you to squeeze more than 840 Mbit via LAN to the cloud. And it says that the ports are gigabit.
Please write what you think. Tomorrow is close;) I would not want to go back to the store with the return.

Why did you use it? This utility is not for flashing, this utility is for recovering from unsuccessful flashing.
It was necessary to reflash through the web interface.http://www.asus.com/en/support/FAQ/1010600/

Daymon3 @ 11.12.16, 20:46

All according to the instructions.

It is written therehttp: //dlcdnet.asus.co....1142589983.1481565918

In this way, right in the store, reflash so as not to go far :)

And how to put the 157 channel? In the settings of a maximum of 112.

Perhaps this channel is on alternative firmware.

Because out of the box there was an ACTUAL version for today. And in the opposite direction, as you probably know, it will not be possible to flash through the web interface. Therefore, I used the prog to force a flashing in the debugging mode of the device. The only way! : yes2:

After talking with ASUS tech support, today it became known that different channels need to be installed to support 5 Hz by various devices. I was recommended to put channel 36 on a width of 80 or near it. Everything is working. My LG G3 Dual is now always online for 5 hertz.

Daymon3,
I'm on my own, rt-n18u, without any problems stitching through a webmord and on tomato and hggomes, from the latest firmware. Router 2016 in., I bought 3 months ago. Probably on my so far there is no verification.
So it was not wrong to sew.
