Modem > Router1 > Switch > Router2 (R2 doesn't work, stops switch)

[BAD311]

Hello all,

Not sure if this is because of the make/model #'s of our switch and Router2, but I'm in need of having two wireless routers in my business.

We have Comcast cable. The comcast modem connects to a Belkin N1 Wireless router (Router1). From the Belkin router I have a wired connection to a Linksys 8 port switch that I connect to customer systems.

I now want to add to that switch another Belkin wireless G router that can have a different SSID/pass making it super easy to connect to the internet for my customers machines (for testing, updates, etc...)

Why do I want the second router? So I don't have to go in and delete the SSID/pass from every machine (time = $$$)

However, when I connected the Router2 to the switch, it instantly killed internet to the switch and the Router2. As soon as I disconnect Router2 from the switch, the switch connections work perfectly.

Should I get a list of makes/models of the routers/switch I have or is this a known thing? You'd think the switch/router2 would work? But they stop sending/receiving once router2 is connected.

Thanks all!

Is the second router handing out DHCP? you should have that turned off...

Do VinylxScratches said.

Maybe both routers are using the same IP address on the LAN side, such as 192.168.0.1? Connecting them to a switch at the same time would cause them both to not work. You just need to change the IP address of the 2nd one to something on the same subnet but different, such as 192.168.0.2.

Also, I'd put the two routers on different wireless channels. There are only 3 non-overlapping channels: 1, 6, and 11. Do a site survey to see what channels any nearby wireless networks are using and try to avoid using those channels.

I think it should be this way TBH.

Router 2, has 192.168.0.2 but the same gateway as router 1 and router 2 should be going through router 1. That way it's on a separate network but still has internet access. I don't really see how it works if they're both going to the same switch if the switch doesn't have separate VLANs.

VinylxScratches, it should work. It's just like having 2 wireless access points with one of the access points also acting as a router. Router 1 would have 192.168.0.1 and Router 2 would have 192.168.0.2. Router 1 would have its DHCP service turned on and would make the connection to the Internet. Router 2 would have DHCP turned off and wouldn't connect to the Internet, so it's just like an access point.

Ahh thanks guys! I'll go try your recommendations tomorrow. Sorry for the late response, Anandtech doesn't auto-send replies, so I didn't know anyone replied, haha.
