tplink Wifi Router settings' IPs are interfering

[Mr.Stork]

I have 2 wifi routers, Archer AC1200 one for upstairs, and TL-WR740N / TL-WR740ND one for down, both are from TPLink, so the settings' ip are same i.e 192.168.0.1. So, when I hooked the new router in my pc, it shows the settings page for the new router, but when I removed it and put back the old router, chrome remembers the new router's page and tries to open it and it can't (screenshot below). I can get around it by using Incognito mode or other browser (or probably even clearing cache, which I wont).

 

Thats well and good, but my intent is to connect all of the routers using Ethernet, so how will I open either because the Newer model's settings page will be opened, probably. Is there any workaround for that, can I maybe change the ips for either routers?

 

I'd rather not use ethernet, instead I'd use my old one as 2Ghz wifi repeater for my new one without any ethernet, but if my routers can't reach each other, I'd have to resort to using ethernet.

(our house is old and the walls/ceiling are very fat around 15", wifi have trouble getting through)

 

Thanks

Change either of their IPs to something on the same subnet. 

 

I'd suggest moving one of them to 192.168.0.2 and changing the DHCP scope on whichever is acting as the DHCP server to exclude 192.168.0.2 from the pool.

Not sure how to do that, I changed the Default Gateway from 192.168.0.1 to 192.168.0.2, but opening the new ip doesnt open the settings. Can you please help me out with how to properly change the ips?

 

Edit: Changing the Default Gateway made me loose internet, so I changed it back lol

K I found it, what to do with the subnet mask?

Leave it as is.

 

Make sure to disable DHCP on one of the routers and on the other, change the DHCP range to start at 192.168.0.3 so it doesn't assign 192.168.0.2 to another device.

So you have 3 routers. You have a conflict because some of them are using the same IP or distributing the same IP in the same local network.

Select 1 as main router and the other as SLAVE / Access Point.

Main router : 192.168.0.1, router mode, DHCP enabled

Second router: 192.168.0.2, Access point mode, DHCP disabled, default gateway 192.168.0.1.

Third router : 192.168.0.3, Access point mode, DHCP disabled, default gateway 192.168.0.1.

All subnet mask : 255.255.255.0 (no need to change).

 

On the main router DHCP option:

- start ip address : 192.168.0.100

- end ip : 192.168.0.199

 

you can have DHCP enabled on the slave router but you need to specify the start-end so it is not overlapping the other.

such as 2nd: 192.168.0.200-210, 3rd : 192.168.0.211-250.

Actually I got 2 routers. But anyway, I got what you mean, your explanation is really good, thanks a lot.
I need to know one thing tho, as I understand DHCP provides ips to devices within the specified start and end ip addresses, so why would I want to keep DHCP enabled on the slave routers, can't the master router assign ips for the devices under the slave router?

[SupaKomputa]

Yes it can get all from the master.

But it can be handy if you have slave dhcp server in the rare situation where the master is offline, the devices on the slave network can still connected (without internet ofcourse).

You can also assign different subnet for the slave router like 192.168.10.XXX.

In the high traffic environment like an office, using multiple dhcp server will be beneficial to isolate each departments and also lower the main dhcp server (router) load. But for home usage the benefit is close to none.
