BT will supply this, and it's the cable with red ends.

You can buy Cat5e cables elsewhere, but they might have different colours. If you use a regular, yellow-ended Ethernet cable that BT supplied with Full Fibre, it will still work but will be slower. If you can't see the icon, check that there are flashing green lights where the cable goes into your computer. If you're having trouble connecting to the internet, make sure the Hub's main light is blue. If you've manually changed your network settings like your IP address or DNS server in the past then you might need to change these settings back to automatic for your BT Hub to connect successfully.

How do I connect my device to my BT Hub by Ethernet cable?

Author Topic: Why would a too short Ethernet cable cause network problems? Read times. I was having some strange network problems with my PC, from taking excessively long for the link to come up to slow network performance. There is an 8 inch or so patch cable going from the onboard NIC of the embedded Atom platform to the internal switch. When I replaced that patch cable with a 3 ft patch cable, everything worked perfectly.

Thinking that cable is defective, I connected it to a network analyzer and no matter how I flexed the cable, it always tested fine. If I use that cable to connect some other Ethernet devices together, it works fine.

Why would a cable that is too short cause problems? Cryptocurrency has taught me to love math and at the same time be baffled by it. Cryptocurrency lesson 0: Altcoins and Bitcoin are not the same thing.

If a transmission link is affected by reflections bEcause of bad impedance matching, a short link may be worse than a long one reflections are more attenuated.

Paulo Professional Tinkerer, www. Psi Super Contributor Posts: Country:. You could try force the speed to mbit instead of auto. That can help sometimes. Greek letter 'Psi' not Pounds per Square Inch. Did you also move the Atom system further away from the switch when you changed the cable? Maybe it was some interference from the switch causing problems with the Atom mainboard Switched to 24 inch and problems went away. This oscilloscope isn't telling me anything all I see is a squiggly line The boards remained in exactly the same place.

I found another short cable that is about the same length and I get the same problem. So I'll just use the 3ft cable and find a way to neatly route it. Actually, with all the work that was going on, it's a little messy and all the cables look like they need to be carefully rerouted.

I suspect the equalization circuits are not expecting such a short cable does Gigabit have a minimum cable length specification? I found the datasheet for the RTL and there's a 3. Maybe the receive amps are powered from the 1V rail and cannot accept strong signals. Such an issue would be quite problematic in embedded Ethernet, where the signals run on one board or several boards connected by connectors like NICs on plug in cards with a switch in the backplane without going through any cable.

The problem coul be in the transmitter as well. A transmitter with bad impedance matching ie poor transmit return loss will not attenuate reflections from the receiver end much.However, there are some easy steps to follow, using easily-available equipment, that can make phone wiring repair easier.

I encounter faults from bad phone wiring repair very often. It keeps me in business. Twist and Tape. This results in the cables eventually snapping due to bending stress, or corroding.

Far too bulky. Then the tape dries out and falls off. Finally, if exposed to damp, the cable corrodes and causes problems…. Take a look at this horror photo….

Possible but not advisable.

There are better ways to effective phone wiring repair. Well, if you have the patience… But you still have to insulate the joint with something. Or, even worse, when you come to work on them, putting them right takes a long, long time. If only they knew…. It makes positive electrical contact.

I have a friend that just cut 2 lines, spliced em together, and threw some electrical tape around it. I dont even think he soldered it.

Of course, YMMV, and dont blame me when you get inconsistent packet errors. Go to a store that sells networking cables, and ask for a coupler. Mine was 7. Works like a charm. I've used the couplers, they work just fine. Shame on you guys, I'm surprised it took until the 5th post to come up with a coupler. This reminds me of a good story, we had an intern in the datacenter at the last place I worked. My boss and I were doing some new cable runs and came up about 10" too short.

My boss jokingly said "I wish I had my cable stretcher about now". Well the intern was eager to help out and said "Where is it? I'll get it for you".

So we sent him running around the building asking people if they had seen the cable stretcher. A jack and plug may look nicer, but you don't always have someplace to mount it. They are rare, but do exist.

I have had mixed results when using a coupler on a CAT5 run over feet. There have been times where the alternative was to pull a new cable, which meant pulling up some freshly laid carpet. As far as cable stretching goes. Can I extend my ethernet cable line?

All connections from the outside to your master socket is BTs responsibility and you are not allowed by Law to do any changes to that side of the connection, including adding an extension cable.

This is why there is a Master socket as the lower removable section is for you to connect internal wiring to.

So you will have to get BT to reconnect you and you will probably be charged for it. Message 2 of I prefer to use the little 6 way junction boxes you can get, fit one of these or similar to the incoming cable and then run another piece of normal telephone cable to the master box, there will only be 2 wires in use not the normal 4.

Alternatively you can re-locate the master box or even fit a second master box. Message 3 of Thx for above replies, astarsolutions can you pls explain how 2 run a second master box in line?
