The IP addresses from your wifi router configuration are causing conflicts.
The IP addresses from your wifi router configuration are causing conflicts.
I possess two Wi-Fi routers—an Archer AC1200 upstairs and a TL-WR740N/ND down—both from TPLink, sharing the same IP address (192.168.0.1). When I connected the new router to my PC, it displayed its settings page. After removing it and reinserting the old one, Chrome retained the new router’s interface and failed to launch it. Using Incognito mode or another browser helps, but clearing the cache isn’t an option. My goal is to link all routers via Ethernet; if the newer model’s settings appear, I need a solution. Can I modify their IP addresses? I’d prefer not to rely on Ethernet, so instead of using the new router as a 2.4GHz repeater without it, I’d rather connect the old one directly. However, if the routers can’t communicate, Ethernet becomes necessary. Our home’s walls and ceiling are thick—around 15 inches—making Wi-Fi signals weak.
Update one of their IP addresses to fall within the same subnet. It would be better to assign 192.168.0.2 and adjust the DHCP scope so that this address isn't included in the available range.
Not sure about the steps, I switched the default gateway from 192.168.0.1 to 192.168.0.2, but updating the IP didn’t fix the issue. It worked better when I went back. Since changing it caused me to lose internet, I reverted it just in case. Can you clarify how to set the correct IP now?
You possess three routers. A conflict arises due to shared IP addresses or overlapping IP distribution within the same local network. Designate one as the primary router and the other as a slave or access point. Main router: 192.168.0.1, DHCP active, router mode enabled. Slave router: 192.168.0.2, access point enabled, DHCP off, default gateway set to 192.168.0.1. Third router: 192.168.0.3, access point enabled, DHCP off, default gateway also 192.168.0.1. All subnet masks remain unchanged at 255.255.255.0. On the main router, configure DHCP options: start IP 192.168.0.100, end IP 192.168.0.199. You may enable DHCP on the slave but ensure distinct ranges—such as 192.168.0.200 to 210 for the second—while keeping the third from 192.168.0.211 to 250.
You have two routers, but you're wondering why DHCP is still active on the slave routers. It's because DHCP handles IP assignments automatically, so even if the master router manages IPs, the slaves still rely on DHCP to get their addresses. Keeping DHCP enabled ensures devices receive consistent IPs without manual configuration.
It can retrieve everything from the master. However, it proves useful when you have a slave DHCP server in rare cases where the master isn't working. Devices on the slave network can stay connected without an internet connection. You can also set a different subnet for the slave router, such as 192.168.10.XXX. In busy environments like offices, using several DHCP servers helps separate departments and reduces the load on the main server. For home use, the advantages are minimal.
