I have a Netgear WNDR3400 v.1

I installed it as a guide https://www.dd-wrt.com/wiki/index.php/Netgear_WNDR3400

The mega version 29940, the router seems to fuse.

I have installed dd-wrt to have VPN functionality with OpenVPN protocol.

The router seems to work, I can access the dd-wrt control panel, I set DHCP but can not access the internet with my computer.

The connection light to the network port on the netgear is orange.

I think I have some parameters in the setup phase, can anyone help me? Also indicating some guidance?

Update:

I did some tests and the Wifi connection reached the Internet, the problem comes with cable connection.

At the moment I have the following wiring:

Cable PC + Wifi PC -> dd-WRT -> router -> modem -> Internet

192.168.10.x LAN -> 192.168.5.x WAN -> Internet

help me.

Thanks

On the Setup/Vlan page check your vlan settings.
I think you have an 100Mb router and then VLAN0 should have the WAN port and all LAN ports should be on VLAN1.

For more information see: http://www.dd-wrt.com/wiki/index.php/Switched_Ports

Did you do a full reset/erase nvram?

If that does not help it is possible that there is a bug in this build you could try another recommended nuild, as always do a full reset and configure manually

Sorry for the delay with which I answer.

My router is a 10/100 Mb.

I think I have more problems, so I tried to simplify things to solve a problem at a time.

Now I have configured my network this way:

PC cable + wireless PC -> ddWRT -> modem -> Internet

192.168.5.X -> 192.168.5.254 -> modem -> word wide web

This way I can access the internet with any PC.

On the router, however, port 1 light is orange while the other 3 are green.

From testing that I did the problem is not determined by the type of cable from the type of PC that is connected to it, the problem is the router configuration, because with the original software this problem did not exist.

I can not access the router via telnet (I use a program called putty), I receive a "wrong login" error when I enter the same username and password that allow me to access the webGUI. I also tried to enable remote connection via telnet on the ddWRT firewall, but the problem persists.

From WebGUI I can see the configuration of vlans: vlan0 I have lan ports 1,2,3,4 and on vlan1 i have wlan with bridge on LAN.

I tried to reverse the doors from WebGUI but the router does not connect to the Internet led to the connection with the ADSL is orange.

Thank you

Accessing the router via telnet is simple RTFM.
Username is always root

Ok, I came in.

Following this guide http://www.dd-wrt.com/wiki/index.php/Switched_Ports


With the command

[egc]

Before tinkering with the vlan ports try a full reset aka erase nvram.
Check how to do that for your particular router, older broadcom units need a 30/30/30 reset, newer routers need: "erase nvram" from the telnet/command prompt.
But beware these commands can brick your router so research what is necessary for a full reset for your particular router

EDIT: according to : https://wikidevi.com/wiki/Netgear_WNDR3400v1 you should do a 30/30/30 reset

[spike200]

I did a 30/30/30 reset reporting all the parameters to the original ones, after I got connected with the telnet I found the same results.
Can I proceed with changing the vlan parameters?
Should the vlan2 parameter be deleted?

[egc]

I am no expert on VLAN ports (actually no expert at anything) so I can not help you in this case, but the settings you have are very uncommon, either you have vlan0 and vlan1 or vlan1 and vlan2, you have alle three and that is uncommon.
With a lot of routers port 0 is the WAN and port 1,2,3,4 are the LAN ports, 5 is the internal CPU
So with 1 Gb routers you have vlan1ports=1 2 3 4 5* (the asterisk signifies the default I think) and vlan2ports=0 5 in this way the Wan port 0 is connected via the internal CPU 5 to the four Lan ports.

Your setup implies that 4 is the Wan port and then you should just delete Vlan0ports. This probably is the netgear stock default.

However it is possible that DDWRT wants its own defaults and then you should delete vlan1ports and vlan2ports and add: vlan1ports = 0 5

As said, i hope that someone with more knowledge will chime in. Research first

[spike200]

If I go to modify something with the telnet I can then reset the settings with a 30/30/30 reset? Or reinstalling dd-WRT?

[egc]

Well that is the 64.000 dollar question, probaly yes but I am not 100% sure.

If you boggle up the vlan's you often can connect via wireless. So be sure that you have wireless access.

[spike200]

Ok i try.

Thanks

[spike200]

To delete the nvla2 line, what option should I give in front of the nvram command? -d? delete? del? rm?

[egc]

e.g.:
nvram unset vlan0ports
nvram commit
reboot
