Hi!
Sorry, this question may be very basic, but I am just out of energy to solve this
I have a Linksys WRT 1900AC V1 router, and I want to replace my ISP router.
The set-up is as follows:
1. The fiber goes through the wall into a splitter.
2. The ISP router is currently in bridge mode for internet, and shares TV to the decoder.
3. My WRT1900AC has the bridged ISP router connected to the WAN connection, and the WRT1900AC takes care of routing internet.
This kind of works, but now I want more TVs and less cables.
So, what I want to do:
1. Connect the cable from the fiber splitter to the WAN of my WRT1900AC
2. Use VLAN to distribute the traffic in lan ports 1-4 as follows:
Port 1: Internet
Port 2: TV
Port 3: Internet
Port 4: TV
WIFIs: Internet
I have read that my ISP uses the following tags:
IPTV: 101
Internett: 102
Then I'd like to have an option to separate the networks connected to port 1 and 2 from the networks connected to 3 and 4 (because they will be routed to a rental appartment in the house). But for now, just the ports above.
If anyone can help it would be great!
I understand I need to put it in the startup script somehow?
I have been struggling to get this to work in past few days, without success.
There are several posts by <Kong> and Per Yngve Berg that say "it should work exactly the way it does under openwrt" by using swconfig utility.
I think the key word in that statement is should.
All those posts seem to be suggestions only, but I believe they have not been tried and proven to work by their authors.
I may be wrong in my assumption and would love to hear from someone who tried and was successful in getting it to work on WRT1900AC by using swconfig utility.
Another confusion is that there is no good resference showing default configuration, which port is on which VLAN by default.
The OpenWRT wiki has some information on WRT1900AC v1, but I think it may be incorrect.
What I forgot to add is that it should be doable.
VLANs work on the stock FW so it should be possible to do it in DD-WRT. _________________ Roman

I am trying to setup several VLANs (preferably tagged by IP Subnet), but the tutorials that I am finding are either command line or reference using the Setup -> VLANs tab, but on my recent build (v3.0-r30880M kongmv (11/14/16)), this tab doesn't exist. What was it replaced by? _________________ Linksys WRT1900ASC V2 DD-WRT v3.0-r30880M kongmv (11/14/16)

You have to put the commands into the startup script.
E.g. working example for the 1900AC V1:
swconfig dev switch0 set reset 1
swconfig dev switch0 set enable_vlan 1
swconfig dev switch0 vlan 1 set ports "5t 0 1 2 3"
swconfig dev switch0 vlan 2 set ports "5t 4"
swconfig dev switch0 set apply
ifconfig eth0 up
ifconfig eth1 up
vconfig set_name_type VLAN_PLUS_VID_NO_PAD
vconfig add eth0 1
vconfig add eth0 2
You have to put the commands into the startup script.
E.g. working example for the 1900AC V1:
swconfig dev switch0 set reset 1
swconfig dev switch0 set enable_vlan 1
swconfig dev switch0 vlan 1 set ports "5t 0 1 2 3"
swconfig dev switch0 vlan 2 set ports "5t 4"
swconfig dev switch0 set apply
ifconfig eth0 up
ifconfig eth1 up
vconfig set_name_type VLAN_PLUS_VID_NO_PAD
vconfig add eth0 1
vconfig add eth0 2
Have you actually tried above in the startup script on a WRT1900AC v1 and it was working for you?
If so, can you please tell us which build you used for that?
Well, I do have a WRT1900AC and I did try it and I can tell you that it does not work.
Besides, I am not sure that if following would accomplish anything:
Code:
swconfig dev switch0 vlan 1 set ports "5t 0 1 2 3"
swconfig dev switch0 vlan 2 set ports "5t 4"
On fresh install, nvram shows that ports 1,2,3,4 (LAN) are on VLAN0 and port 0 (WAN) is on VLAN1.
Port 5 (CPU) is on both VLAN0 and VLAN1, tagged, tying them both together.
The swconfig on WRT1900AC enumerates ports a bit differently, I tested them one by one and they are enumerated as follows:
LAN ports are 0, 1, 2, 3
WAN port is 4
CPU ports are 5,6
LAN ports appear to be on one VLAN with port 5
WAN port appears to be on one VLAN with port 6
So above two lines of swconfig would move LAN ports on to VLAN 1 and WAN port on VLAN2, so essentially it will be the same as before, all LAN ports on the same VLAN.
Or maybe I am missing something? _________________ Roman

Disregard these variables as they are used on Broadcom units only.
If above nvram variables are invalid, how are then ports allocated to VLANs on clean, new DD-WRT install on WRT1900AC (Marvell)?
Are they on VLAN0 and VLAN1 or VLAN1 and VLAN2?
I'm also interested in assigning one of my LAN ports to a separate VLAN, tried all the above including Kongs commands and never got it to work. Definitely looking for some help here.
