Help with project Wireless router and PT router

[BUZZARD2020]

I am trying to connect a PT router to a WRT300N wireless router with a crossover cable or straight through. I want the PT router to be the gateway. I have the WRT300N router set up and connected to 2 PCs using WPA2 personal encryption.

I am not sure how to connect the two, I've tried both cabling methods, I've tried different IP addresses for the gateway "192.168.14.1" and wireless router "192.168.12.1" I've tried using similar IP addresses for the router "192.168.14.1" and WR "192.168.14.2" and I still cant get them to connect so that I could ping one router to another or ping the computers from the router.

Any assistance would be appreciated.

This is for Packet tracer

Assuming neither end of Ethernet RJ45 has auto-MDI, the rule is like wired ports require a cross-over cable, otherwise you use a straight-through cable.

I believe PT, if you use the Ethernet auto select cable select option, will chose what's needed, i.e. either a cross-over or straight-through connection.

It's helpful if you attach your (compressed) PT lab to your posting.

I changed what I was doing, I'm using a WAP instead, I figured out the issue. The problem that made me change to a WAP instead of the router is that I didn't know how to make the wireless router see additional hops past the PT router.

The last problem I am faced with is that I do not know the steps to make a printer server that connects to the "fake printer" because the printer doesn't have https capabilities so I can't make the server "look at" the printer so to speak, and as such, the server cannot "share" the printer.

I suspect that could be managed on a real WRT300N within its routing configuration section but the PT variant doesn't support that, so doing what you did makes sense.

As to the printer issues, not something I've used in PT, but hopefully later today I'll pull down your PT lab (thanks for providing it) and see if I have any better luck.  If I do, I'll let you know.

Thank you, that would be awesome.

Already, I've played a bit within PT and I've searched the Internet for doing what you've asked, regarding setting up a print server.

As far as I can tell, it's not possible in PT.  The best that can be accomplished, is setting up the printer, and server, that both can be pinged, demonstrating network connectivity.

Yeah, that's what I thought. I thought it might be possible considering that's what my teacher was asking for, but I really appreciate the conformation.

The problem isn’t the cable type but the setup. To make the PT router the gateway, configure the WRT300N as an access point, not a router: connect a straight-through cable from the PT router LAN to a LAN port on the WRT300N, put both on the same subnet (e.g., PT router 192.168.14.1, WRT300N 192.168.14.2), disable DHCP on the WRT300N, and keep DHCP enabled on the PT router so all PCs get 192.168.14.x addresses with gateway 192.168.14.1. This setup allows full ping connectivity between routers, PCs, and the internet.

If you do all that, haven't you, in effect, changed the WRT300N into a L2 switch, which also acts as an AP?

If so, what's the benefit to doing what you've described, rather than:

I.e. replacing the WRT300N with an AP.
