Hi all. I need an Ethernet cable that goes from one of these ends to the other. What would I call it so that I can search for it and buy it on the internet?
Thanks in advance.
Thanks all - turns out I was being really dense. Thanks to the commenters who helped me sort out my thickness!
- I don’t think so. They aren’t compatible. Even in the photo, you can see that the right cable only has 2 pins, while an Ethernet connector has 8 (I think). Definitely more than 2. - What are you actually trying to do? What device are you trying to connect, and to where? - My guess is that you’re going to need a modem, but please give more context. - Thanks, I’m connecting my phillips hue hub to my router. I had a cable that did it previously, but the openreach guys used it to connect the fibre to the router. - Is this the hub in question?  - I think you need a perfectly normal Ethernet cable. It would help if you show a photo of both the router and the hub.  - Yeah, those are both definitely normal Ethernet jacks. Neither takes a phone cable. You should just need a normal Ethernet line. - OMG, thank you so much, I was being super dense! - Did it work? As I said, the ports on the router look a little weird, but if a normal network cable plugged into them then you’re good. - As others have said, you weren’t being dense at all. Your question wasn’t stupid, just a little misguided, and it was very quick for us to figure it out with just a little bit of back and forth. I wish all tech support was this efficient! - BTW, if anything I was being a bit rude when I said I wasn’t sure why you thought the other end needed to be different. Apologies for that. Looking at the photo of the router you sent around the same time, I can see why you thought that, it really does look different. - Thanks, yeah, it’s all back and working now. 
 
 
- RJ45 to be specific. RJ11 is phone 
- The router ports are too short, wtf is that? - Just a little squat. More than tall enough for an rj45 to plug in though. I think they look a little tight because it doesn’t have the same amount of bezel as a lot of boxes will have around the ports. 
 
 
- Forget about your first image/question then … that my friend needs just a regular lan cable. RJ45 at both ends. No telephony involved here - So, two of the yellow ones? - Absolutely; although the color itself isn’t important. You need RJ45/RJ45 and I’d suggest cat5e or better - like: https://www.ebay.com/b/Cat-5e-Ethernet-Patch-RJ-45-Ethernet-Cables-RJ-45-8P8C/64035/bn_7112482108 - Thanks. Turns out I literally had the cable I needed and was just being to silly to plug it in because I didn’t think it was the one. Thanks so much for your help! 
 
 
- Thanks, sorry for being a dumbass! - No need to apologize “no stupid questions” remember ? ;) 
 
 
- What router is that? - BT Smart hub 2 - The ports on the router look weird. I want to look more into this but I’m afk for the next hour. Will look it up more afterwards. 
 
 
 
- that’s the one - Then you just need a normal Ethernet cable. I don’t know why you thought the other end needs to be different. - Because I was being thick. Apparently there are stupid questions! - Never a stupid question, people make mistakes, people see things wrong or brains just misfires. No shame in that, learning is important and that’s what you did and that’s the best part - Thank you! 😊 
 
 
 
 
 
- There is no way they connected fiber to router with a freaking phone cord. - Either you misunderstood or they lied but what you need is a standard ethernet cable with the same connection on both ends to connect a router to fiber. - Also if someone is professionally installing hardware they shouldn’t be reusing your existing cables anyway. - You have an XY problem. If what you need is to connect your phillips hue hub then just say that instead. 
 
- You can actually make multiple rj11s from a single Ethernet cable. 
 
- FYI ‘phone line’ is known as rj11, ‘ethernet’ is rj45. There’s different types of ethernet cable, most common is ‘cat5e’ that can transfer data up-to 1Gb/sec. Newer cables are usually ‘cat6a’ which adds shielding and up-to 10x the data transfer speed. - So when you go looking for a new one for whatever reason, you have the technical name and don’t have to look at the pictures and hope the listing is actually what you need. 
- Michael - dad joke detected - take my upvote 
 
- That stupid shitty 6-pin abomination is called RJ11 6P6C. - Clearly 6P2C - Yeah, but I still prefer “stupid shitty 6-pin abomination” name for clarity. - I doubt you really lived the analog phone era /s  - I lived in the era when they taught us to count instead :) - Count von Count send his greetings. Said he remembers you and me very well! 
 
- My house growing up had a bunch of those (female) ports around and we had the adapters to convert them to RJ11. - Those existed with femail rj11 built in 
 
 
- Not sure why it’s shitty - easy to assemble, cheap, effective at eliminating contact noise with a high-compliance wiping contact. - the only shitty part is the exposed retaining clip which gets broken off 
 
 
- What did it do to u? - Exist. Just look at it! Abomination as it is! 
 
 
- The smaller end is RJ12, the bigger end is RJ45. - The question is, what are you trying to do with it? RJ12 is/was typically used for telephone connections, RJ45 for Ethernet. Generally speaking, they don’t mix. - If your plan is to connect a computer to a RJ12 socket on the wall, that’s not going to work. If you’ve been told the socket on the wall is “the internet”, you’re likely going to need a modem in between that socket and your computer. - No, it’s to connect my phillips hue hub to my router 
 
- The gray one only seems to have two contacts, so it for phones/modems. The yellow one is more common for networking. For compatibility reasons often used in outlets too. The yellow one is RJ45, the gray one RJ11 - So, what you are looking for is an RJ45/RJ11 cable. (cat-3 cable will suffice but higher works too). Alternatively you can use an RJ45/RJ12 (same specs). The difference is RJ12 has 6 wires where RJ11 has only two. Since you have only two in the gray one, both can do the job. 
- Looks like you’ve got an rj45 to an rj11 cable. That would be Ethernet on one side and telephone on the other. 
- That is one weird cable! I’m guessing someone took a regular ethernet cable and replaced the connector on one end so it could be used for ADSL. - Ethernet will still run on it, but only at like 10mbps. Which would be enough for your Phillips hub, but please just toss it and replace it with a proper ethernet cable. 
- The cable on the left is commonly known as an Ethernet cable (RJ45) and the cable on the right is commonly known as a telephone cable (RJ11). - But I will echo what people are saying in the comments, you just need a regular Ethernet patch cable (RJ45 on both ends). 
- 8P8C to 6P2C 
- There is no such cable in existence. You need to provide more context
