coaxial cable causing internet problems

About 5 years ago when we had cable internet installed, the coax cable wasn't strong enough so they installed a new one. Tighten that end of the cable to make firm contact. My ISP has approximately 100-120ft of coaxial cable from the front of my place to where my modem sits. Instead purchase thicknet coaxial cable, also known as 10Base5. High-frequency signals are partially reflected at impedance mismatches, causing errors. My internet speeds dropped today from their usual ~115Mbps to about 30Mbps. This type of cabling is also thin and is extremely susceptible to interference. In addition to the possibility of loose connections, connectors must maintain their reliability under all kinds of conditions. For Series 6 cable, typical loss values are as follows: The cable modem could possibly be the culprit, but the voltage was measured on every cable line coming FROM the house including the telephone, cable television, and internet cables. It has a larger conductor, which provides a much better signal quality, and the dielectric insulation is thicker. My cable internet is very inconsistent. æ k s /) is a type of electrical cable consisting of an inner conductor surrounded by a concentric conducting shield, with the two separated by a dielectric (insulating material); many coaxial cables also have a protective outer sheath or jacket.

Making connections to coaxial cable provides yet another challenge to maintaining network performance. Coaxial cable, or coax (pronounced / ˈ k oʊ. The term "coaxial" refers to the inner conductor and the outer shield sharing a geometric axis. I guess you could just use 20 times the O.D. Step 4: Barring any of the aforementioned problems, replace the modem. If you’re experiencing connectivity issues, follow these troubleshooting steps: Contact your Internet service provider (ISP) to verify that your device is activated. Open a Command Prompt window from your Start menu and run a command like ping google.com or ping howtogeek.com. Today’s coaxial connectors have to be high-performance and provide nearly flawless signal transmission to accommodate the very large amounts of traffic going back and forth from provider to end user. The copper-based cable is piped into your house from the cable service provider. A key to coaxial cable design is a tight control of cable dimensions and materials. Connect the other end of the cable to the coaxial cable extender. In addition, my cable internet speed went from 3mpbs to 12! There are several possible causes of your Internet outages. Then again, maybe not. Sometimes it will work very well (25Mbps/1Mbps), but when it's not working very well it's not working at all. This can be an issue in most households where there is more than one device that needs a signal. Step 4: Turn on the TV. One of the most common causes of upstream power problems is splitters. One final tip: If the "cable" light on your modem is off or flashing, it's almost certainly a problem with the wiring between the cable company and your home. If the dimensions on the inside of that cable change, so does the impedance of that cable. If the problem isn't with your home network or your PC settings, you may be "losing your lease," which means that for some reason your PC has lost the IP address provisioned by the cable company. As far as the diameter for winding coax, I figure 4" diameter (not radius) for RG58, 5" for RG8X, RG6, RG59, etc., and 8" for RG8, RG213 and LMR400. Connection issues might result from poor line quality over the DSL phone line or coaxial cable line, bad cable connections (bent cables or pins), or missing or incorrectly configured software. Remember to tighten the cables on both splitter and TVs by gently screwing in the caps to the connectors. Premises, Q: My Internet connection, which I get through my cable company, has been intermittently dying on me, but my television works fine.

RG-6 cable was designed to fulfil this requirement. I contacted my provider, Comcast, and eventually the tech suggested that there might be "static" build up in the cable line - he/she had me unscrew the cable connection from the modem, and touch it to "discharge" the static. The Surprising Way in Which China Censors the Internet, The Monumental Challenge of Mapping the Human Brain, This Is the World’s Smallest Functional V-12 Engine. Because your cable internet comes to your home from a hub that you share with your neighbors, even just a few households using the internet at the same time can slow your network traffic or even cause dropping. With the millions of connectors installed, there are a variety of ways they can become loose or even begin their installed life loose, and in any given home it only takes one loose connector to cause performance issues. It has input lines connected to the existing cable wire and multiple output lines. Then split on a three way splitter with my cable modem on the -3.5 connection TV's on the -7's. Coaxial cable loss is normally specified in dB loss per 100 feet of cable. Damage from rough or improper handling and accidents is the most common type of damage. Coaxial cables can be used to carry signals for internet connections, but internet signals run at higher frequencies than traditional analogue video. If a physical impairment occurs, the impedance at that point is no longer 75 ohms, which can lead to transmission problems. My amplifier is on the main incoming Coaxial. Too much network traffic. Those are figured using 10 times the cable O.D. There can be a problem when coiling up coax, but it's a mechanical problem. for radius, and then multiplying by 2.
