Ethernet splitter

[Craig234]

First, I'll admit the ridiculous reason for this question.

I have an older PC with Diablo II. I have to log on and refresh the characters to avoid their being destroyed every 3 months. I haven't played in years, but keep the ones left.

I Iost the CD's (and rebought them and lost them again), so the one thing I use the old PC for is that. Every few months, switch the ethernet cable over and refresh them.

It'd be more convenient to have a splitter to not have to move the cable.

Question 1: If I only use one PC at a time (ther other turned off), can they simply use a splitter that sends the connection to both PC's?

Question 2: Depending on the answer to #1, looking for a recommendation for a cheap but reliable device - either a splitter or a switch to connect the ethernet internet cable to both PC's.

Yes, I should probably think of something better to do about the game.

Just buy a cheap 5-port switch and leave them both plugged in. That's the best option and should cost you less than $20 on Amazon or Newegg.

It also depends on how your network is.work is.
you have a Router then it is OK, if you connect it to a Modem, it might. cause a problem.

 

[Craig234]

Thanks for the answers. I use a router from Comcast I think (wish we had better companies and services. Where the hell is public internet in Silicon Valley?)

 

[JackMDS]

Get a switch plug the cable that comes from the Router to it Then plug the two computers to the switch.

What model is the device in question? Then we know what to config the lan like.

You could also buy a pair of RJ45 splitter, if you don't want an extra device.
But keep in mind that you would only be able to get 100BT.

You mean the router? I think it's some Motorola Comcast router, that can do internet and internet phone (which is why I haven't replaced it yet with a bought modem/router since I use it for phone also).

Not sure what 100BT is, but that's a rather confusing diagram they have in the description.

Just buy a gigabit ethernet switch like JackMDS and others have suggested.

It makes a difference which one. If it's just a modem, buying a switch won't share the connection. If it's a gateway, modem/router combo, then the ones they've rolled out have a 4 port switch on the back. Getting another switch would be no issue with the gateway

You sure it's a router? Sounds like a modem with phone support to me. You will need a router if that's the case.

 

[mxnerd]

Post your modem or router brand and model #

Well, is the definition of a router that it provides wi-fi? If so it is a router since it provides wi-fi. Ethernet in, ethernet, phone connection, and wi-fi out.

 

[Craig234]

Post your modem or router brand and model #

That'd be the easy thing you'd think, but my setup has it a bit of a hassle to get. I'll do it if needed for this discussion.

Doesn't look helpful - here it is with the hex and ip addresses removed:

Well, without the IP address info, cant really assist.

I'll try though. You're behind a SOHO If its:

10.x.x.x
192.168.x.x

172.16.x.x - 172.31.x.x

Anything else....and it's just a modem...

Didn't realize the ip was useful.

The only one looks like the IPv4? It begins with 10.0.0.

 

[ch33zw1z]

Yup, so you have the gateway. I'd be surprised if you didn't have more ports on the back to use. I helped a few friends and family while Comcast rolled them out a couple years ago. They all had a 4port switch built in. Either way...u can just get a gigabit switch, hook it to the lan port on the gateway, and it will extend layer 2 for you.

Well, ya, if there are actually more ports so the second PC can just remain plugged in that's easiest. I'd assumed it's not the case since I hadn't set up the service for two PC's and know there are conflicts when two PC's try to use the same connection, so I assume it has a way to switch. I'll check for that.

Ok, you're kinda confusing the issue. Standard comcast service gives you one public IP. That's what the modem gets.

In steps a router. The router takes the public IP on the WAN side, and uses NAT to "share" it on your private LAN via Private IP and ports. Private LAN IP ranges are not routable by the internet.

Back 15 years ago, ISP's used to get finicky about routing to your SOHO LAN. Not anymore.

You can have as many devices as the LAN IP range can support.

I have about 20 devices on my LAN. To the world, it all comes from one IP.

In short, your service from Comcast isn't tied to a one PC account.

Edit: to really ensure my advice is sound. The make and model of the device, and maybe a picture or two of the back of it.

Based on what you're telling us, a switch would get more devices on the wired LAN no problem. Anything you plug in should be a 10.0.0.x IP

Jeezus, the conversation above looks like someone trying squeeze information out of a spy. Maybe waterboarding would help.

You have a gateway/router You just need to plug the old PC into your home network and it should have access to the internet. You might need to buy an inexpensive network switch, as noted above, under $20. But your gateway may have a built-in switch (with multiple ethernet ports), so an additional switch may not be necessary. Which is why knowing the model number would be helpful.

Well, is the definition of a router that it provides wi-fi?

No. A router routes traffic between separate broadcast domains. Between different subnets.
Access Point (AP) provides WiFi.

The problem is that a cheap consumer device may have modem, router, switch, and AP functions all in one device. Depending on whom you ask, such thing is called "modem", "router", "WiFi" or "excrement".



PS. Some ISP's hand out private addresses to their clients. Therefore, those clients are behind NAT even if they have no router.

Really. I don't understand why it's so hard for OP to find the brand and model# of the modem/router he owned/leased.
