Guide: Enable Wave2 on RB4011 WITH both 5GHz and 2,4GHz working simultaneously

Removed, don’t want no hate.

But do you realize that you are writing in the official MikroTik forum
and that you can’t even decide what it does or doesn’t do if the user reads what you wrote on the forum?
You cannot use the forum to enforce your licenses.

Ridiculous.



I didn’t opt in and read it anyway, so what happens now?

Ridiculous.



No need, you wrote it on the official forum and surely someone from the MikroTik staff will read it…

Ridiculous.

No worries, sorry, removed it.

Thanks for sharing this dude. Unsupported or not, it was clear that you intended to share this with others for the sake of it, while ensuring that people understood that it was not supported or endorsed by MK, and that it obviously could have dangerous results.
But people like to nag and point out all of the useless and mindless stuff, like the legality of what you wrote or that it could crash your device… like if it was unclear after you stated that this was not official and not supported…

Stay safe and please continue to be who you are.

the cat always growls unnecessarily

would like to see the OP’s solution again

The cat complains about the added bullshit, not that he did well or not to “share a method”, which then doesn’t work…

The original first post ,except for the text formatting.

There is a way to have both drivers simultaneously in use on RB4011: the wifi-qcom-ac package (Wave2) for the 5GHz interface and the old wireless driver for the 2,4GHz interface.

It has been an issue for many RB4011iGS+5HacQ2HnD-IN users that installing wifi-qcom-ac package disables the 2,4GHz interace. Well not anymore. Please note that this method IS NOT officially supported by MikroTik, so let’s get the following away first so that MikroTik won’t hopefully “fix” this method.

These instructions that follow are under strict copyright license. The license requires you to not contact MikroTik support should you read and follow the instructions regarding any issues you face with your RB4011iGS+5HacQ2HnD-IN device. The following method is not officially supported. If you run in to issues, please rollback the changes before contacting support regarding any issues with your RB4011iGS+5HacQ2HnD-IN. Should you fail to adhere to these licensing conditions, you are liable to pay any expenses incurred by SIA Mikrotīkls from your support request to SIA Mikrotīkls if such issue is caused by this unsupported configuration. Do not read further if you wish to not adhere to this license.

The steps to enable both drivers at once are as follows:

Install wireless package (if not already installed)
Install wifi-qcom-ac package
Reboot
Disable both wifi-qcom-ac and wireless packages (if either is enabled)
Reboot
Enable both wifi-qcom-ac and wireless packages
Reboot


After this, both packages will be active and the 5GHz interface will be running on Wave2 drivers (wifi-qcom-ac) and the 2,4GHz interface will be running on the old drivers (wireless).

Just to reiterate though: this is an unsupported configuration. Do not contact MikroTik support regarding any issues you face should you use this configuration.

It does work, both interfaces are usable. I have been using it for a month now as I have multiple ESP32 IoT devices at home that require 2,4GHz. However I don't want people sending spurious support requests to MikroTik when obviously this shouldn't be possible to do nor do I want to stir hate on the forums.

Works for my case though, your mileage may vary.

Thank you for the guide! I was looking for a way to do this for a long time. OFC I understand that there is no warranty or support for this configuration available. But its a homelab and experimenting is whats most fun!

Could you please clarify what version of RouterOS you're were using? I'm on 7.12.1 and didnt upgrade because I was afraid 7.13+ would break my wifi completely.

For sure 7.13+


From 7.13 changelog:

Notice - Starting from RouterOS version 7.13, significant changes have been made to the RouterOS wireless packages. […]
[…]
3. The existing “wifiwave2” package has been divided into distinct packages: “wifi-qcom” and “wifi-qcom-ac”, and the necessary utilities for WiFi management are now included in the RouterOS bundle. RouterOS and “wifi-qcom-ac” packages alongside each other now fit into 16MB flash memory.
[…]

Reporting in after some testing. On 7.15.3 it does not seem to work.
When wireless is enabled it disables the 5G interface in qcom-wifi
Logs show:

DefConf gen: Unable to find wifi radio data
error while running customized default configuration script: interrupted

Tried deleting wlan1 from bridge, disabling it in wireless package and deleting and reinstalling wireless package altogether. Too bad, on the new wifi package PC connection speed improved drastically (from 400-500mbits to up 1000-1500 dl)

Maybe it works only on a specific version of ROS.
