Router > Ethernet Cable > Wireless/Ethernet Cable

[Bob Marley]

Hi, so I have a router, that has a 100ft ethernet cable coming from it. I need to be able to attach a router to the end to broadcast a wireless signal from that ethernet cable, but also allow me to plug another ethernet cable into the end of it to use for a wired computer. So, what do I need to get to allow me to do this?

Just make sure that the bridge/router that you purchase has ethernet jacks in the back. Most of them do. Can't you just run the 100' ethernet cable from the modem to your existing router instead of using a bridge?

Will I be able to just run it to my current router and I won't have to setup a bridge of any kind? It'll just work like that?

Plenty of wireless hubs about with ethernet ports, I have Edimax, TP-Link and D-Link
I have also just replaced all my network cables with powerline (Mouse problems, they keep eating the cable)
So far it seems as fast as the old cat 6 system.
If you did that, it may save you long cable runs.

I have a similar system set up here at my home and work - so here's how you need to set it up:

Hardware: One non-wifi router with 4, 8, 16 or 32 ports, whatever you need. One WIFI router with 4, 8, 16, or 32 ports, whatever you need. 100 feet of ethernet Cat5e cable with RJ45 ends, one 6 ft or so cable with RJ45 ends to plug the last computer in.

Layout:

Wired router will have a WAN port, and the rest will be LAN ports. Assuming you're connecting all this to the internet, you'll use a short network cable to connect the WAN port to the cable modem (or appropriate network interface).

100 foot cable will be plugged into one of the LAN ports, and will go to the WIFI router and be plugged into one of the LAN ports (NOT the WAN port!). Last computer can be plugged into any of the LAN ports on the WIFI router.

Configuration:

You can only have ONE router acting as your DHCP server. If you have two set up as DHCP they will fight over 'who is in charge of what'. The other router can have a static IP set up for managing it. So - you could set the main router with an IP of 10.0.0.1 with DHCP server enabled, and the WIFI router manually configured to 10.0.0.2 with DHCP server DISABLED.

You can specifiy the DHCP IP range to anything like 10.0.0.100 through 10.0.0.200, this will give you plenty of headroom if you need to create more complex static networks, while having a good range of dynamic IP addresses for tablets, phones, laptops etc.

This setup will allow any plugged in wired devices to find the main router to get it's DHCP information. Any WIFI devices will connect to the WIFI radio system to link to the network, then it will look for the DHCP server on the main router to get its IP information. Remember, the WIFI connection in many regards is separate from the actual network protocols, it acts as a 'invisible wire', nothing more.

Like I said, it's very similar to what I have here at my house. I have:

Business class Comcast gateway in my basement in server room (acts as the router) -> 8 port network switch -> wifi router upstairs.

1U Webserver hooked into gateway.
10tb media server hooked into gateway.
Backup server hooked into gateway.

Desktop unit hooked into 8 port switch.
network printer hooked into switch.
basement htpc hooked into switch.

Upstairs HTPC wired into wifi router.
Raspberry PI media player wired into wifi router.

Phone accesses WIFI.
Laptop accesses WIFI.
Tablet one accesses WIFI
Tablet two accesses WIFI

Anyone else accesses WIFI as needed.
