Splitting the Internet via cable splitters?

[Prophet1c]

Hello.

I'm sorry for English, it's not my first language, also sorry if I posted this where it shouldn't belong or I broke some rule.

 

So I have a question about something I'm not very good at, Internet modems and routers. Last week I finally upgraded to fast internet ( well it's still slow, but I really can't get much faster where I am) but my router ( or modem, I don't quite know) can't keep up with the speed and it's limiting me to a 1/3 of a full speed. So the setup is optical modem > Wifi Router > to my PC. When I connect it directly to my PC I get the full speed, but then my Wifi is not working.

So I was thinking is there any way I could use some kind of a splitter, with one cable to my PC and other to Wifi Router?

 

Thank you, V.

what you are looking for is called an ethernet switch. Just go to any of your online shopping sites and search for "5 port ethernet switch"

It might be simpler and cheaper to buy a gigabit router. No need for a fancy one

Just to make sure I can connect ethrenet switch directly to my "optical" modem and from that I can connect both my PC and my Wifi router? I don't need to configure anything, it's a plug and play type of thing if I understood correctly?

I forgot to tell, that's not possible at the moment for various reasons. Anything that does requires me to call my Internet service is no good currently.

You don't need to involve the internet company to change the router. Just connect a different one the same way you connect your PC

Modem - Router - Switch 

 

I havent done it but dont see why you cant go Modem - Switch.  I have a few switches in my home network but they all go the top route.  About to buy this one, for example, after I price check some out today (need another switch for the far side of the house)

The fact that you get internet when you plug your pc straight into the "optical modem" makes me believe that its likely an optical modem/router combo. So most likely yes.

I was replacing my old router few months ago and I had to call them to "enable" it, like they said. Something to do with IP.

Wouldn't it be the same speed if I connected router > Switch?

I can post a pic of it:

All a unmanaged switch is, is a passthrough (basically).  If that is a TP Link router (antennas) then where that black cable is coming off the router would be to the switch, then from the switch to all your hard wired devices

Yes, that's a TP Link router, but I can't get enough data, speed? trough it as I would like, so wouldn't it be the same as right now?

That black cable is connecting TP Link router to a PC, one white cable is connecting "optical" modem ( I'm calling it that way for no other reason than to distinguish them in my head) with TP Link router and the other white cable coming from the wall I have no idea whats it for.

 

So theoretically I could go Modem > Switch then from Switch one cable to TP router and the other to PC?

If your modem is only doing modem things, and not a combo unit basically, then going modem -> switch would meant he first device connected that asks for an IP gets the public IP and everything else gets nothing. In this case the fiber box is almost certainly more than just converting fiber to copper and has routing/switching functionality built in too.

Who is your ISP? What speeds are you paying for? What is the make/model of the wall-mounted ISP devices?

The black TP-Link device is your wireless router. What is the model?

Your thinking that wiring your PC to the wireless router is somehow affecting wireless connectivity is not how networking works. Unless it's a very underperforming router.

1) On contract it says 350/30 Megabit. Model is Dasan h665.

2) Model of the black router is TL-WR940N

3) No, I don't have the problem with WiFi, my issue is I don't get the full speed when I connect from the black router with cable to PC. I do get full speed when I connect from white modem ( wall-mounted) to a PC.

Because the TL-WR940N only has 10/100 Mbps ports you're not going to get over 100Mbps whereas your ISP device probably has gigabit ports.

 

Edit:

My suggestion is to get a better router with gigabit (10/100/1000) ports across the board.

I don't want to be rude, but I knew that router isn't good enough, that was never the issue. I was asking is it possible to bypass it. And the answer is yes!

Works like a charm! Thank you very much!

The problem is, as you said, when you plug directly in the wifi doesn't work. I suspect when you plug directly into the optical modem you get a public IP address which puts your PC at much higher risk of being attacked. Additionally, if you do get a public IP address from your ISP then you're only likely to get 1 address unless you pay for more so using a switch will result in the first device that asks for an address getting the public address and the rest without.

 

Now this all assumes your optical device doesn't have any NAT or other functionality built in BUT because you say it works then that removes my theory and it is a "modem"/router combo.
