Default Ethernet home network help, please

Okay here's the problem. I have a std Lynksys home router that will emit wifi and supply four hard wire outputs. And it all works fine supplying hard wire to 3 devices.

If I take out the router and install a simple 8 port switch in its place, obviously I have no Wi-Fi, but it will only feed one hard wire device, the other two are dead.

Two new 8 port switches do this, why?

I'm going to say your router was giving out DHCP to clients and a standard switch would not do this. Try a static IP in the other devices maybe or check the port configuration of each port on the switch.

A "switch" is essentially a dumb repeater - traffic in, traffic out. It won't route the traffic properly outbound, and it won't provide IP addresses for all the devices on your network.

You can plug the switch into the router, and the router will continue to assign IP addresses and your wireless will keep working. (I'm assuming your goal is to have more than 4 devices)

So your setup could go Cable/DSL Modem -> Router -> Switch -> 7 devices (plus technically 3 other devices on the router)

I thought if you needed more hard wired ports and still keep wireless, you would use one of your hardwired ports coming out of the wireless router into a muti-port switch, from there you have unlimited ports. That is how I have mine set up.

thanks - my intent is to move the router out into the main common area and not hidden in a back room closet like now...so I wanted to distribute the hard wire in the closet and then plug the router in to emit wifi out in the living room...

You can do this as long as the router is the first step connected to your cable/dsl modem - IE modem and router in the common area, one wire back to the closet with the switch. (there may be other ways around this, but this is the easiest)

thanks yeah, can't do that...the modem has got to stay back there...maybe just a wifi enhancer/repeater in the common area?

Gotcha. I assume you don't want to run TWO long wires, one from the modem to the router in the far room, then another back for all the other devices, but that's also an option.

The other solution is to use a wired router, and then put the wireless router in "access point" mode. Then you'd have only one wire from the back room to wherever you placed the wireless device.

Repeater is a legit option although may not work quite as well as you want it to, another is just a "better" wifi router or one that is extendable with antennas.

I'd check out the $30-40 repeaters on amazon, some have good reviews. If you happen to have an apple airport/airport express lying around those also have an extender mode.

There are definitely many ways to accomplish what you want to do. You're getting a little tripped up because the average wireless router is intended to be an all-in-one device. (combining router, switch, and access point in one)

If your goal is to extend Wifi get yourself one of these and don't look back.

http://www.netgear.com/home/products.../WN3500RP.aspx

My router is on the first floor one side of the house and kids always complaining of slowness and bad signal upstairs on other side of the house. The extender plugs into an outlet and stays there, you can play around with different places in your house and if you want Wifi in the backyard lets say, plug it in outside and there you go. Creates a secure extended Wifi network of your existing SSID. Plug and play pretty much, had mine up and running in 30 seconds.

You can get a more powerful router but do not forget that each device needs to talk back to that router. If you don't have more powerful devices as well you don't gain anything.

All you need is a wifi access point. Leave your router where it is and install an access point where you want it. I like these:

http://www.ubnt.com/unifi#aplr

What many people call a wireless router is actually router and a wifi access point combined in one box. They don't have to be that way and in commercial installations usually separate components are used. You only want one router. You can have as many wifi acces points connected to the router as you want.

Once you go hard wired you won't go back...

I ran cable in the attic last year and I still can't believe the difference. I went from cable modem -- wifi router -- switch -- switch. The rooms are home run to the switch by the router, and the second switch is on my home entertainment center, the router runs everything at my desk. That said I checked the wireless a few weeks ago and there are still 27 devices connecting to it. It's really amazing these days that everything from the playstation to our phones is using it.

Don't forget you can do powerline ethernet. It works surprisingly well. I use one to 'hard wire' an xbox 360 that I use for a media extender. Way better connection/throughput doing that than I was getting with wireless. Much easier in my case than running a wire upstairs. Though I did wires to my entertainment center and downstairs. 40 bucks was a no brainer.

I was going to recommend Powerline networking. I have my wifi router at one end of the house and a wifi access point at the other end that is connected by powerline. Works very well.
