Ethernet card failure
Comments (16)So there are 2 NIC cards and you cannot install drivers for either of them. At this point perhaps we should turn our attention to the motherboard. Have you tried using a different PCI slot? You might also try installing the video drivers to see if there is an issue there as well. Why did you decide to replace the CMOS battery? Nothing wrong with doing that but I was curious as to why you did it. Did you remove the power cord from the rear of the computer each time you went in making changes? As you had a PCI NIC card is this a home built computer? If so what motherboard is in there? If factory built give us a make and model of the computer....See MoreEthernet and DVR
Comments (6)While it works best to have your modem, router, and patch panel all centrally located, if it helps solve your current problem, the modem could be "virtually located" in the mechanical room. In other words, if the modem is currently being fed it's signal in a particular room, and that room has a network jack, you could then send the internet connection down to the mechanical room and to the router. While you are not splitting the signal, in the traditional sense, and it does not weaken, you still have some limitations. The output from the modem goes into the router. The router then acts like a "traffic cop" directing information from the modem, to-and-from the individual ports on the router. The modem has an IP (internet protocol) address assigned to it from your ISP (internet service provider). The router then assigns IP addresses to each device connected to it, and carefully routes data from each port's address through the main IP address and back again - all using just a single connection. The limitation is in how much data each connected device is downloading, or uploading. I'm in a rural area with DSL that has about 1.5 Mbs download speed. To stream something like Netflix in standard definition, that connection speed is about the minimum you can get away with. Can two people watch two separate streams? No. Can four people browse the internet? Sure. We have three computers normally on-line, home security cameras, internet radio streaming and some misc equipment - and no problems. Download and upload speeds for residential service is almost always asynchronous, meaning you can usually only upload at a fraction of your download speed. This usually works well, since that's the way we normally use the internet. However, if you have something like home security cameras that can be viewed over the internet, you going to be uploading a lot of data and possibly slowing traffic on the download side of your internet connection. So, again the limitation is in the amount of data being received and sent. As a matter of fact, most 4 port routers usually allow a second router to daisy chain to it and create additional ports....See Moreethernet wiring, which cable to choose?
Comments (25)There may be some confusion since this there are a couple posts on this same installation. You can not connect a switch directly to the cable modem unless it is a "gateway" - a router is required. Even if it is a gateway they can be very problematic. The router connects the WAN (from the modem) to the LAN. The switch interconnects the devices on the LAN. Most current routers nowadays are optimized for streaming A/V as one of their features. They monitor their own built-in (switch) ports and prioritize data to help ensure smoother media flow. A switch on a router port, feeding multiple ports, will generally not receive this same prioritization. That is why I recommend connecting streaming media devices directly to the router. Streaming media on a home network from NAS makes no difference. The chain should be: cable modem, router (with it's ports feeding streaming media connections), and a switch connected to one of the router's ports, feeding the other network connections, for best overall performance....See MoreComcast or electrician does ethernet wiring?
Comments (15)"Is it enough to have my office and family room added ethernet outlets or is it better to have all the bedrooms ethernet outlets added?" Wired Ethernet in the bedrooms is a good idea since it can allow for streaming video to Blu-Ray players/televisions from services such as Netflix and Hulu. It can also allow for streaming of audio & video from network attached storage devices or for video security systems. "Living room has a cable modem coax cable outlet, do I still need to add a ethernet outlet? Yes, unless you want all those cables coming into your living room. Typically you pick some type of utility space with AC power to place the router. Then, the cables from each of the rooms terminates at this point where they are connected to the router. The output from the cable modem is also fed to the input to the router. If they router does not have enough RJ45 connections, you can expand it with a network switch or only plug in the connections which will currently be used....See MoreRelated Professionals
