Router's connection stop with double adaptor cable over 2 metres

A Former User

What is the purpose of the double adapter for your case? If you don't mind me asking.

johnpoz

So your using a coupler??

Like one of these?

Not exactly sure what a double adapter is?? Dual nic? You have a dual nic in pfsense? And trying to use it as a switch or you have each port on a different network?

Could you please give some more details on what this double adapter is? And how your attempting to use it.

Hello, here's the image which I hope will explain it.

Image is only showing an image icon from my end, so I hope you can see the image? I added a shared cloud photo link.

The purpose is that the wall has 1 Ethernet port, and there is one main computer, but sometimes a laptop is also in the room and needs an Ethernet connection. Both machines are rarely on together, but the ease of use without plugging/unplugging cable is the main benefit.
However the main computer1 has no Internet ever, when the laptop computer2 has the long (5 metres?) Ethernet cable also connected.

Use a $5 5-port switch and forget about the Y-adaptor.
It only works with Y-adaptors on both ends anyway and was supposed to be used for POTS phones on CAT5 cables only.

not seeing an image… But yeah get a switch!!!

Okay, thanks. I found a 4 port manual Ethernet switch for $13. Cheapest I could find.

I don't see an image either … pure guesswork with a dash of Sherlock ;)

What the hell is a "manual Ethernet switch"?
Get a switch like this: https://www.amazon.com/TP-LINK-5-Port-Ethernet-Desktop-TL-SF1005D/dp/B000FNFSPY/ref=sr_1_2?ie=UTF8&qid=1471856483&sr=8-2&keywords=5port+ethernet+switch

No idea what a manual ethernet switch is either.. The link jahonix pointed to would be fine if all you want is 10/100 but who runs that anymore?

Get a gig one.. Here is major brand d-link 5 port gig for under $15

So 5 more than the 10/100 one..

Thanks, I bought the Gigabit.

johnpoz

let us know how it works out.. If your prime you prob have it tmrw if you ordered from amazon ;)

@johnpoz:

… 10/100 ...

These Y-Adaptors use two of the 4 pairs in a CAT5 cable for each jack. This gives a maximum of 100Mb per host and that's why I linked such a switch. That's all.

This is probably such an adaptor:

and that's how it's wired:
