Ezwifi extender v4

Hi there, I have been trying for 2 days, time to ask for help.
I am using an ezwifi extender v4.
My land lord has a wall lan socket connected to VLAN 900 on his system.
I tried connecting my laptop straight to it and when setting vlan id to 900 it worked.
Now I wanna connect my router to it and have my wifi extend it.
I tried mannnnyyyy things. Now I am creating switch vlan with ID 900,
CPU tagged and port1 tagged, other ports off.
There is also the standard ID nr 1 with all untagged.

Then I changed the my network interface


and added the Vlan to it. Then disabled DHCP and praying for the best. Nothing....
What else can I do and what am I doing wrong. Thank you very much!

Are you running OpenWRT?

haha yes! Powered by LuCI Master (git-15.248.30277-3836b45) / OpenWrt Designated Driver r49390

It appears you are using firmware that is not from the official OpenWrt project.

When using forks/offshoots/vendor-specific builds that are "based on OpenWrt", there may be many differences compared to the official versions (hosted by OpenWrt.org). Some of these customizations may fundamentally change the way that OpenWrt works. You might need help from people with specific/specialized knowledge about the firmware you are using, so it is possible that advice you get here may not be useful.

You may find that the best options are:

  1. Install an official version of OpenWrt, if your device is supported (see https://firmware-selector.openwrt.org).
  2. Ask for help from the maintainer(s) or user community of the specific firmware that you are using.
  3. Provide the source code for the firmware so that users on this forum can understand how your firmware works (OpenWrt forum users are volunteers, so somebody might look at the code if they have time and are interested in your issue).

If you believe that this specific issue is common to generic/official OpenWrt and/or the maintainers of your build have indicated as such, please feel free to clarify.

without going to much into it, for my question, what would be the basic setup so i can see if i did it right or can make it work with the knowledge we have now?

You are using a vendor fork that is based on an ancient version of OpenWrt. You need to ask the vendor for help because they have almost certainly changed things to make it work on that hardware, and the base version is so old as to be incompatible with the syntax of all modern versions of OpenWrt. So.. in short, no, we cannot help you with that version as it would likely only result in breaking your device.

Just to be clear, I mean, how is it supposed to work. You make a bridge between the vlan switch interface and your network to connect to a remote vlan?

Yes, in older swconfig devices, you setup a Vlan on the switch, then create a bridge with that vlan, and finally an unmanaged network interface to which your wifi ssid would be attached.

so like the image i posted should work. I dont have an unmanaged one, but it links to my wifi interface.
PS and thank you for your support!!!!

Yes, that's how it works with modern versions of official OpenWrt. What you're running is not from the official project, and it is based on a version that is almost 10 years old... syntax and theory of operation have changed dramatically over the past decade, so all bets are off regarding your device.

just to update you all. I downloaded ez311-openwrt-23050rc3-en got the vlan via port 1 connected to the wireless, changed the ip of the router and dhcp and added a vlan interface without management to the interfaces and connected it to the lan and it is working :).

Oh darn, I wanted to use the wifi extender function again and did not manage with the version on it, so i thought, lets just revert back to stock. Download the latest really old image from the ezwifi site (2021) loaded the images, ignored the warnings (yes I am fully responsible) and started flash. Result, booting and nothing happening. Bricked? What to do now? Reset options are not working. Waiting for 15+ minutes nothing. Wifi not turning on, any other options? TANX

Since your device is not supported by the official OpenWrt project, you'll have to ask the people who provide/know/maintain the "ezwifi" firmware you used.

found a tftpd recovery for it, fixed!
