When retracting a RJ45 plug through narrow tubing or around corners, the clip tends to snap off, effectively making the network cable useless in most environments. The rubber dome (most commonly referred to as a cable boot) nearly always prevents that from happening. You wouldn't know how many network cables I've seen with broken off clips.

From experience, those retention clips break off a lot on the first sort of cables - those are fine for cables that are well protected and/or going to be plugged in and forgotten, but the moment those clips bend the wrong way, they break, and you end up with a cable that dosen't clip in place. They also snag each other sometimes and are just a PITA. Cable ...

If you don't want to replace the cable or install a new jack, you have a few of options: Glue it into a coupler or a short extension like one of the following (with the coupler you will need another short run of cable on the other side): Repair it with a zip tie. Use this guide for instructions: ...

The short answer: Not really The long answer There are a couple main differences between $4 HDMI cables and the more expensive ones. Connectors More expensive cables usually have more heavy-duty connectors. This is obviously important as you want to be able to reuse the cable once you buy it. Some cheap HDMI cables will break after plugging/unplugging a ...

Take a look here for a very good explanation: http://computer.howstuffworks.com/question352. They're ferrite beads used as an anti-EMI and anti-RFI measure (chokes): Another source of noise is the cables connecting the devices. These cables act as nice, long antennae for the signals they carry. They broadcast the signals quite efficiently. The signals ...

Typical 802.11g Wireless has a theoretical maximum of 54Mbps. Typical wired 10/100 Ethernet has a theoretical maximum of 100 Mbps. So in theory wired is faster. However, these speeds are only on your local network. Most high-speed internet connections range from 1Mbps to 25 Mbps. Even on faster internet connections you're only approaching 1/2 of the ...

The only benefit to HDMI is that you don't need a second cable for audio. HDMI essentially combines a DVI connection with audio. Actually, because of this, you can acutally get converters that go from HDMI to DVI for a few bucks. Because it already has a DVI connection in it, the quality over the HDMI connection would be identical. The only reason you'd ...

That's an anti-snag boot meant to protect the clip when pulling the cable through other cabling, conduit, and other tight spaces. You can carefully clip it off if you don't care about the anti-snag capability. There are some other anti-snag styles that can work better in tight locations: I've found that first style works well in our 48 port ethernet ...

The black connection provides power and data. The red one is power only. The second cord should be used if the black one doesn't provide enough power to power and/or charge the device. You'll see a lot of external hard drives come with the same type of plug (though usually both are black). EDIT: To answer your second question, plug the device in using ...

Yes. This article answers most of your questions. Is there special outdoor-rated cat5e/cat6 I should use? "Preferably, special exterior or direct burial CAT5 cables should be used for outdoor runs instead of ordinary CAT5." If put it in a dug trench, do I need to put it in conduit? "Exterior-grade Ethernet cables are waterproof and thus do not ...

5 meters is the maximum USB cable. You can get further by connecting USB hubs serially (maximum of 5 hubs chained this way). You can't just use USB extension cables due to timing issues. From the USB FAQ: Q1: How long of a cable can I use to connect my device? A1: In practice, the USB specification limits the length of a cable between full ...

It's entirely possible to cut off the plug and install a new one, but you will need a crimping tool. It's about $15. The thing is, your local store will probably charge you more than $15 for a cable - even if you buy it online, it'll probably be close to that when you take shipping into account. Therefore, it's cost-effective in my opinion, even if you only ...

As others have pointed out this is a ferrite core used to reduce the electromagnetic interference produced by the cable. The European Union updated the EMC (electromagnetic compatibility) directive in 2004: The purpose of electromagnetic compatibility (EMC) is to keep [electromagnetic interference] under reasonable control. EMC designates all the ...

I would guess that it is most likely an F Connector: http://en.wikipedia.org/wiki/F_connector Yes Canadian Tire would most likely carry an F Connector. If not you can easily purchase these connectors (or already crimped cables) online (just search google for it).

Twisted Pair refers to the cable itself. Two conductors inside the cable are wound round each other to cancel out electromagnetic interference. A Twisted Pair cable could carry all kinds of signals. A Crossover Cable refers to how the cable terminators are connected at the end of the cable. In this case the connectors are connected asymmetrically so you ...

The original eSATA specification does not provide power. You'll need a USB cable or wall adapter to power the hard drive. The new eSATAp specification utilizes the USB bus to provide power over one cable, but is relatively rare. The easiest way to be sure if you have an eSATAp device or not is to check the plug. This helpful image from Wikipedia shows ...

You have cable internet and this is either 75 Ohm rg-59 or rg-6 quad shield coaxial with a compression F-connector.

Typically that noise happens when computer and speakers have different ground levels, explained here. Are you sure that you did not also change anything in that regard, different outlets, etc? Is your pc connected to other devices, antennas, network switches, etc? Try connecting your speakers and computer at the same power outlet, with an extension cord. ...

It could... possibly. You're not likely to have any problems. Many people do it themselves. If you are already receiving a marginal signal, a splitter might add enough signal loss to cause problems. If you have problems, I would suggest having your cable company install it for you. Most will do it for free (or possibly a small fee). They will have the ...

I did the same with conduit. This way you can run regular wire inside and if you ever need to run additional wires you just feed another one through. I did this for my securtiy system and added the Cat 5 later, I am not sure that I wouldn't have just used wireless had I not already put the conduit in there. You can now purchase outdoor rated cable, that is ...

Normal solution : Wire them with Cat6 double-shielded at 80 meters length with repeaters at intervals. Better solution : Run fibre optic in-between and end off with Ethernet Cat6 and hubs on both ends. TC3210 Ethernet Fiber Media Converter (not very expensive)

Only your ISP can give you a fixed IP address. You could look to using a VPN to a device on a fixed IP address (for instance a virtual server you managed yourself), but that's about your only other option. Alternatively you could talk to the admin of the server and see if they can set it up so that you can use a VPN to access the server.

This kind of plug is called Schuko and it's a de facto standard in many European countries. From Schuko - Wikipedia: "Schuko" ( /ˈʃuːkoʊ/) is the colloquial name for a system of AC power plugs and sockets that is defined as "CEE 7/4". A Schuko plug features two round pins of 4.8 mm diameter (19 mm long, centers 19 mm apart) for the live and neutral ...

It is a Ferrite Bead. They're used to reduce and dissipate high frequency noise. To prevent it from moving on the cable, it is overmoulded with plastic. Functionally, it is a dissipative low-pass filter. It's basically an inductor with very high reluctance, so the magnetic field which it forms get dissipated as heat, rather than reflected back on the ...

The best"-est" way When your cable ISP fails you, switch your router off of cable and over to your DSL service.. Use your meaty human hands, a Rube Goldberg Machine, a sufficiently parented child, a hammer, etc.. And just switch services manually... The 'easy'ish way Step 1) Install pfsense on a crappy old computer with 3 nics (1 for your LAN, 2 for ...

These handheld devices are useful, since they test the cabling on the physical level and can help discover problems (cross-talk, wrong impedance, etc.) which are difficult to diagnose otherwise. If you pulled some cable too much, or some turn inside your wall is too sharp, your network will "kinda work", but you won't get maximum throughput, or you'll get ...

A standard (internal) SATA cable should be required, Wikipedia has a picture (the required cable is on the left): This will connect to the one of the yellow SATA ports shown on the bottom left (from GigaByte's webpage for the GA-P43-ES3G):

Ethernet does a signal to noise ratio test on the cable before bringing the link up. Since your homemade cable gives you approximately Fast Ethernet results, it is likely that the link negotiated to 100M instead of 1GE. If true, that itself is an indication of sub Cat6 results (in fact, sub Cat5e results). This chart summarizes what Cat5e and Cat6 are ...
