Accessing GUI on Access Point

trevzilla · Post by **trevzilla** » Tue Nov 03, 2015 11:25 am

I've posted this question over at the DD-WRT forums, with limited success. Hopefully someone over here has a little more insight.

So I have three routers in my network. Depending on the configuration of the network, I can't access the admin console of one of the routers.

This is my ideal configuration:

However from my computer I can't type in 192.168.0.3 and access that particular router. The ps3 and receiver DO get internet though. However I can't run ps3 media server from my computer because my computer doesn't 'see' the router. All routers are running DD-WRT and I have 192.168.0.2 and 192.168.0.3 successfully configured as access points.

If I do this configuration:

I can access 192.168.0.3 just fine.

If I do this configuration:

I can still acess 192.168.0.3 just fine.

However as soon as I try this configuration:

I can no longer access 192.168.0.3

Then I tried this configuration:

And now I can't access 192.168.0.2, but I can access 192.168.0.3 just fine. It's something to do with accessing the other leg in the 'Y'. Is there some type of setting I have to set in dd-wrt to allow me to access that leg? I'm guessing it'd be a setting in 192.168.0.1.

Finally, when I try this configuration:

I can access all three routers, however I am no longer connected to the internet. (192.168.0.1 is configured as a router, 192.168.0.2 and 192.168.0.3 are configured as access points)

Any thoughts? I'm completely out of ideas here!

There must be something wrong with the configuration.

1. There should be only one "main" router (192.168.0.1), that is configured as a DHCP server, giving away IPs from let's say 192.168.0.10 to 192.168.0.200. That is the only device that should have something connected to the WAN port. It can also be configured to act as a DNS forwarder.

2. The two remaining "access points" should have DHCP disabled, set to static IPs (192.168.0.2, 192.168.0.3), with a gateway of 192.168.0.1, subnet 255.255.255.0, and the WAN side turned off completely (or used as a LAN port). Do not use the WAN ports on those, connect one of their LAN ports to the main router. They should have NAT translation completely turned off.

For more detailed step by step configuration, see this article on the main site: http://www.speedguide.net/articles/how- ... point-2556

I hope this helps.

First of all, thank you so much for your help. Been tearing my hair out over here, and this is the first response I've gotten anywhere!

Unfortunately, all your suggestions (except the disabling NAT) have been done already. 192.168.0.1 is my main router and is the only one configured to use DHCP:

192.168.0.1 Status

192.168.0.2 and 192.168.0.3 has DHCP disabled, a subnet of 255.255.255.0, and a gateway of 192.168.0.1. I have also made sure that I'm only plugged into a LAN port. (Although I have "use WAN port as a switch" checked on both these routers so it shouldn't matter...but regardless, I'm plugged into LAN)

192.168.0.2 Status

192.168.0.3 Status

You say to turn off NAT on the two access points. I've done some searching and don't really know how to turn NAT off in DD-WRT. Can you help me with this step? Honestly, I have no understanding what NAT really is...

And it still seems very consistent. If I'm plugged into the far side of the "Y" with either 0.2 or 0.3 I can't access the admin console of that router. If they are plugged anywhere else in the line, I can access them just fine.

Again, thanks for the help!

NAT (Network Address Translation) is a mode where every packet is translated and routed (i.e. from internal non-routable IPs to the one external IP provided by your ISP).

On the two access points...
- Make sure the "Internet Connection Type" is set to: disabled
- I would set the two access points WAN Ports to: disabled (assign to switch should work, but just to make sure)
- Try setting the DNS on both access points to be the main router: 192.168.0.1
- Disable SPI firewall

What do you mean when you are "plugged in" to one side of the Y ? You should be able to do this even without connecting a clients with cables at the end, typically they would all be using the same SSID and type of security/passphrase, but on different channels.
To troubleshoot, try pinging the other side of the "Y" to make sure it is reachable, you should be able to get from one to the other.
Also, make sure that each router/ap has a different MAC address, if one is cloned to the other it will not work.

Thank you very much for your help.

Just wanted to get in touch to tell you that I've gotten it figured out. I'm not 100% sure what the problem was, but it seems to be with my TP-Link Router. That used to be my "main" router, but I decided to make my WTG54G the main router and have the TP-link be just an access point. Originally that also gave me some weird problems, but after mucking around with it for a couple hours, everything is working now.
