Help setting up Asus RT-N12 as repeater

5,451 948 October 30, 2018 at 09:57 AM
I have tried to set up this router as a repeater. I followed this guide [techtrickszone.com] and it appears to go fine. I can see the Asus on my network, but when I connect, I don't get any internet access. Pinging from the router also fails.I did make one change in that I changed the IP address of the repeater from 192.168.1.1 to 192.168.1.10 since my primary router already has this ip address. Could this be the issue?

Two devices on the same network should NOT have the same IP address assigned to them.

It's like the mail person trying to deliver mail to 1 address, but there are to houses with the same address...which house should it go to?

So I did the correct thing in changing the Asus to a new address, correct?

Right.

Just cause it's a repeater, doesn't mean it should have the same IP address as something else on your network.

So if I'm following, you have a main router/modem that you connect to the internet through, and you want to add your ASUS as a wifi repeater. You went through the steps in the guide, including where you can see that your ASUS is connecting to your main router/modem.
1- do you have internet through the main router/modem?
2- did you move the ASUS after setting it up, could it now be too far away? You should be able to go into the admin pages of the main router and see that the ASUS is connected by wifi.
3- if you connect to the ASUS with an ethernet cable instead of wifi, do you get internet?
4- I've only ever done this to turn an old router into an ethernet switch, not a wifi repeater, but I seem to recall that you might have to identify the ASUS to the main router as a wifi repeater.
5- when you changed the ASUS IP, how did you do that? On the ASUS itself? Does it have that same static IP assigned within the main router?

The IP address change per se shouldn't be the problem. When you say you can't ping, do you mean pinging the ASUS via wifi from a PC, or pinging the main router from the ASUS?

One thing you could try, which shouldn't be necessary, but might solve some issue the ASUS is having, is change the ASUS back to the original IP, and change the IP of the main router instead, to avoid conflict. That's how I have my network setup, though as I said, my old router is cabled in as a LAN switch, not a wifi switch.

You might try looking at the documentation for your main router, to see if it describes how to attach a repeater.

A couple of other troubleshooting thoughts:
1- you could try temporarily moving the ASUS closer and using an ethernet cable between the ASUS and the main router (might have to reset the ASUS as an Access Point while doing this), as a means of troubleshooting wifi issues strictly between the ASUS and your PC/devices.
2-are there any other devices connected to the main router that share the 192.168.1.10 address?
3-

Hey, thanks for the reply.
1-Internet is fine when I connect to the main router
2-No, I didn't move the Asus, so it should still be in range
3-I will try this when I get home
4-I'll see if there are any settings in the main router to identify the Asus as a repeater
5-​Yes, I changed the Asus IP address in the admin pages. I will check the main router to see if it identifies the Asus as 192.168.1.10
I'll also check if any other devices are connected to the main router using the same address. Good idea!

OK, hope something works! I'm not an expert, but I've done some fiddling with linking routers and troubleshooting my home nettwork. I'd say also make sure that the main router is assigning 10 as a static IP for your ASUS router. The default is dynamic so each time the system reboots, there's a small chance the main router could pick a new IP for any device it sees. There seems to be some memory persistence in those assignments, but at the least, if you assign the ASUS IP at the main router as static, it will prevent another device from trying to get that IP.

Sigh, I've given up on this. Now I can't seem to log in to either the Asus now or my primary router, a Technicolor. I've tried multiple times. Thanks for the suggestions though.

I feel ya. Networking is kind of an impenetrable technology to the DIYer. Best to find a pro.
