Hello, I have a Tp-Link 841 v9 and I would like to create at least one vlan also on the eth network. For the Vlan via WiFi I succeeded. I tried to simply change the swith config but the router hangs and I don't get results.
I searched the internet but couldn't find a step by step guide to getting the Vlan. I have made numerous unsuccessful tests. I attach the images of my current configuration hoping that someone can help me, with all the steps to obtain the desired result.
Thank you Exclamation

The WAN port does not appear to be part of the switch. Port 0 is CPU 1-4 is LAN

Will the problem be solved Question

Having greater command of the language and knowledge of the system can you report the bug Question

Thank you

its not a bug... just those units are like that and not capable of VLAN segmentation....cheap is not always good...to be honest Ive never seen VLAN segmentation to work on 841 nor on 740 units (the lower class)

next level TP-Link 1043v2 or v3 are ok with VLANs find one of them instead, they are also cheap and work great with DDWRT...been using those for ages...it never fails...

Posted: Sat Oct 24, 2020 17:42 Post subject: VLANs on TP Link 841

I tried setting up a VLAN on my 841nd v7 with a version around 41791. I also did not succeed with dd-wrt firmware. The OpenWrt build for 841nd has better support for VLANs, but when I used it with my Archer C7 V2 running r40784 it was not stable. It was as though routing loops were occurring and I could not get it figured out. I wasn't able to identify if it was the Archer C7 or the 841 causing the problem.

You CANNOT do a VLAN on a WRT160NL or a E2100L either.... they are old units but their switch is just NOT capable of VLANs... believe me I tried for many years

The tp-link 841 is now obsolete. What is the minimum reliable unit to have VLANs and OpenVPN support

In my opinion R7800 is the standard followed by EA8500 or R7500v2.

hmmm, what about managed switch with VLAN support, have a look at Netgear switch range...there are some for 20-30 dollars/ponds/euro...

otherwise...
