Home Network Arrangement and Setup Problem

by mdhaze / December 28, 2013 9:08 AM PST

Hi all. There have been similar questions posted here but nothing exactly like my situation. In my house I have ran 8 Cat5e cables from various locations to a common utility point. At that point, a cable modem is installed to provide my internet connection. My goal was to connect from the RJ45 port of the cable modem to the WAN port of an 8 port device to which all the Cat5e cables would connect. One of the cables is wired to an RJ45 port located above my kitchen cabinets so I could place my wireless router within my house at a central location. When all of this was put together and assembled, I could not get my laptop connected to the internet. I could "see" the wireless router but could not communicate with it. Because the wireless wouldn't work when connected like this, I relocated it at the utility point and connected the output of the cable modem to the WAN port of the wireless router directly and got wireless communication with my laptop. One of the other cables was connected to one of the wireless LAN ports to establish a connection to a desktop computer. The equipment I bought to satisfy my original goal was an TP-LINK, Mdl. TL-R860, 8 port, router. The wireless router is an ASUS Mdl. RT-N66U wireless router. Is my problem the fact that I have a wireless router connected to an 8 port router with an IP address problem? Would there be no problem if I had an 8 port switch instead of an 8 port router? If I change the IP address of the wireless router can the original arrangement with the original equipment be used? Thanks for any input you may provide.

I can't see the setup.

Here's how we setup the normal way.

Internet -> (wan port) Router -> 8 or more port hub.

I'm left to guess you want to use another router else where off a port of the hub. If so you never use the WAN port of the second router. GOOGLE THIS -> How to use a router as a WAP?

Thanks for the reply R.. My original post may have been too wordy - sorry about that. The bottom line on what I was trying to do was locate my Asus wireless router inside my house by connecting it to one of the eight Cat5e cables that originate in a media enclosure. In the media enclosure I installed an 8 port router to supply all 8 Cat5e cables. This 8 port router was to connect to the cable modem through it's WAN port.

With this configuration I couldn't communicate with the wireless router. From research on the internet, it seems I have an IP configuration problem (?).

You seem to be saying that if my wireless router is used as a wireless access point then my problem will be solved.

I can't see the setup yet. Try to draw it like this.

Cable Modem -> WAN port of (which) Router.

Router LAN ports -> Other things.

A Router LAN port -> LAN port of a second round configured as a WAP.

That's the known working setup I have done far too many times. Using the WAN port on a second router is nothing I can help with.

In reply to: Sorry

Cable Modem -> WAN port of 8 port router

Router (8 port) LAN ports 1 thru 7 -> Various ports with my home

Router (8 port) LAN port 8 -> Wireless Router WAN port

The wireless router will have no hard wired connections made to it. It will only be used for it's wireless capability.

Thanks, Bob.

Pretty close.

"Router (8 port) LAN port 8 -> Wireless Router WAN port"

The system I use is to move that to the Wireless WAN port and the article of your choice from this search.

If you keep it on a WAN port you must be very good at networking or find someone to fix why it didn't break.
