Reddit reviews HDE RJ45 RJ11 RJ12 Cat5 Cat6 UTP Network Cable Tester for LAN Phone Wire Test Tool

Chances are one of the wires isn't connected. All 4 wire pairs are needed for Gigabit.

Get a cheap network tester. It doesn't have to be this exact one but they should all be similar.

Charging all your neighbors to wire up their Ethernet for $50 bucks a pop: Priceless.

For a single cable it does not matter what spec they used (A or B) since it is a closed cable. It would only be a problem if you wired one end as A and the other as B. Anyone suggesting that it is an A or B problem for a pre-made cable did not read your question.

You could see 100 Mbps if there was damage to some of the cable pairs in the wire. You can get a tester to see if any of the pairs are damaged. The wires can snap inside the line or get pulled out of the connector.

How long is the cable? Also buy monoprice (they sell on amazon) for great prices and pre tested cables that are not shitty Copper clad aluminum (CCA). CCA cables are not to spec and should never be purchased.

Cat6 cables are better but should not be necessary for what you have described so far. If you were buying new I would say go cat6 just because they don't cost that much more.

First try different ports, different devices, then check punch downs/ crimps if still have the issue test it with one of these. Network Cable Tester

recrimp it, you likely fucked up an end. do you have a cheap cable tester, like this? That would tell you what pair isn't working. You can usually find something similar to that at a local hardware store for around the same price as amazon.

Get a decent crimping tool and a cheap tester to make sure your pairs are matching up on both sides. I do this for work and home and will never go back to buying Ethernet cables at specific lengths.

Also, if you plan on running multiple cables, I suggest using different color boots so your cable can all be the same color (since you're buying it in bulk) but the boots are different colors to help note which cable goes where.

To be honest I was doing this as a hobby and wouldnt want to spend $50 on a tool I might only get a few uses out of. I found one on Amazon for $10. Would it be worth it for my needs?

It would if they are using the settings like static IP but most router use DHCP(BTW check if you're using DHCP since it may be a conflict with the IPs), but probably the matter is between your PC and the cable: Check your config, reinstall your drivers, use a tester on the cable and try with another PC in the same cable.

1. Will this suffice? https://www.amazon.com/HDE-Network-Cable-Tester-Phone/dp/B009ZXYI1U/ref=sr_1_10?keywords=rj45+cable+tester&qid=1554393337&s=gateway&sr=8-10
   
2. That makes sense. I'll look into it.
   
3. I guess you're right. I'm probably just nitpicking on it since its a 1G fiber and wanted close to it. It's on the bottom of the priority list for now.
   
   Another noob question, when CLink installed my fiber, they placed the modem/router near my box panel in the walk-in-closet. How do I go on transferring it if I wanted it in my DEN? Fiber box is located in the garage. Also the builder labeled all the CAT6 in the panel but
   
   I really can't figure out 2 cables which says DN1ARC or DR1ARC, it's also the same cable CLink used on the LAN/WAN slot in their modem router for the internet.
   
   Thank you so much!

I use something similar. I would switch to this if I hadn't spent money on my solution already. Bluetooth console is a must have.

SecureCRT offers so many features it would be impossible to list them all. Key ones being it saves your sessions into easy to manage shortcuts and can keep a log of what you do on a device. Very critical to know where you went wrong or did.

Even the most basic cable tester can save you hours of headache. The more expensive ones will tell where the break is and will be more sensitive to the break. I find this is good for testing new cables that I've made. Odds are there isn't a break in the middle of the cable just a poor crimp.

This book may be a little dated, but it was instrumental in my early carrier. I highly recommend a read through.

(This only works if you're putting new ends on the cables)

I am running some cables at my new place and am just using regular 9mm label tape and some cheap clear heat shrink tubing of appropriate size.

I put on a couple cm (about an inch) of tubing, then the boot, then the termination, push the boot into place, apply label, slide tubing into place, shrink it.

if you're running it through walls, use a tester to make sure you know which cable is which.

....This is of course for home use, I might not do this at a larger business. (I'm also subbed to /r/homelab)

I have one of these, should be able to test for the type of damage you'd be looking for https://www.amazon.com/HDE-Network-Cable-Tester-Phone/dp/B009ZXYI1U/

This is what you need to test which pair messed up. Its possible it just needs repunched at the jack or the end recrimped if there is no patch panel.

This is a handy tool once its connected to make sure the connection back to the network is working. A little pricier but it has come in handy quite a few times for me.

You could use a simple cable tester to see if they work, connect it to both ends of the cable and presto. You will see the lights flash on numbers 1 to 8, which means it is sending a signal through each of the cable-strands. If all lights blink, it works.

For seeing what type of cable it is you have, pull it out of the wall/cable-mount/wherever or find an exposed piece of cable. The classification should be stamped on there, cat5e=< is recommended. If it has no markings on them it might be very cheap cables.

Edit: link in post above even more pro solution including cable tracking.

use a cable tester

Buy pass through connectors like these. - EDIT: Good up to Cat5e.

Edit

Here is a youtube video about the same type of connector. Your existing crimper should work, but you will have the extra wire to cut off. Just get a cheap pair of edge cutters.

/Edit

Use a cable tester.

You Tube videos will also help.

This is a PITA exercise. You will get better at it.

Oh, get a cable tester. $9.

Did I mention a tester?

Did I mention do not use a cable tester if the cable is hooked up to anything? Only use a tester to test Both ends of the cable at the same time.

Something like this and a couple patch cables would work fine.

You can try a cheap Cable tester. When I was wiring my house I was doing them directly in the wall and used these. Turns out one of the wires wasn't fully making connection when it looks like it was in there pretty tight. The tester tells you that pretty quickly.

Sounds like the tool. I have one of these ...

https://www.amazon.com/dp/B009ZXYI1U/ref=cm_sw_r_em_api_i_1UHvDbCG8D4EN

... and have tested 100ft with no problems using a make shift RJ45 to alligator clip pigtail.

So something like this?

So I looked a little closer and I'm convinced it has to be the cable. I noticed the port is not lighting up on the first switch for that cable either, so no signal from switch to switch. I'm going to buy a cable tester to confirm. I found this tester on amazon. Is this all I need? https://www.amazon.com/HDE-Network-Cable-Tester-Phone/dp/B009ZXYI1U/ref=sr_1_20?keywords=ethernet+cable+tester&qid=1563130965&s=gateway&sr=8-20
