    How ADSL2+ and VDSL2 are different?

    U-verse triple-play (TV, Internet, VoIP) goes to ~3000 feet (~1000 yards) on a single pair with Max available Bit Rate usually in the neighborhood of 30-35Mbps. With two bonded pair, the distance can be extended to over 5000 feet and still well above 30Mbps (or higher data rates at closer...

    How ADSL2+ and VDSL2 are different?

    In the case of AT&T, VDSL2 is using Ethernet framing over VDSL2, and ADSL2+ is still using an ATM-based transport over ADSL2+ signaling. They go to different types of DSLAMs They probably take the same route to the peering point (since they both would aggregate back in the same CO ...

    Forcing "Repair" in WinXP SP3 when "limited or no connectivity" won't let you......

    Try disabling the wireless NIC, then re-enable it. You could also just put in a static and not have to worry about it. In NIC Properties, the window where you'd select DHCP, there is a second tab for alternate addressing. The default is the IPPA addresses (169.254 ...), but you can put in...

    network wiring problem

    The order of the color is critical, that's why I asked. There is also more to proper termination than just crimping on an end I.e , maintaining the twist to the termination point, pair exposure, and strain relief, To name a couple of the many.

    new AMP crimper defective? or...

    Have you tried different connectors? The ones you have don't, perchance, have a nub on the left side (with the connector's nose up, clip away from you) do they? If you have an already-crimped cable around, does that connector fit into the die?

    Home Cat 5e Network and slow transfers?

    IF you screwed up the pair order when you terminated the cables, you likely have lots of crosstalk interference. Try 100 Half-duplex or 10BASE-T (10 meg, half duplex) and see if it appears to work better ....if so, you have split pair (i.e., it was terminated as {pair}{pair}{pair}{pair} and...

    what is this?

    Those are "protectors;" they are (internally) a gas popper type device. They "protect" from the external surges on incoming lines, and "protect" the company from customers putting damaging voltage on the line upstream. In order to work, there needs to exist a qualified ground connection of ~25...

    Need 8 port RS232 hub to usb

    It sounds like he's looking for a terminal server, but they're usually Ethernet-to-serial. Some of the older ones can do SLIP, so it would be possible to talk via rs232 over IP, between attached units (as long as the device supported SLIP) ... So it could be a serial "hub," though there are...

    Large Cabling Project

    Back before Microsoft acknowledged the existence of TCP/IP, their main campus was flat ... thousands and thousands of nodes yammering away with NETBUI, all bridged/switched (all running to MS Servers .... LOL what a joke). The switches ran Spanning Tree (Thank you Radia Perlman!), so eventually...

    Network is unreliable at 100mbit???

    It'ss not so much the insulation and twisting, it's the pair order (i.e., <pair><par><pair><pair> versus TIA/EIA 568a or b). by putting all the pairs side-by-side, in any order, you will have, at the least, a split pair on pair 2 (pins 3&6) which blows the crosstalk values right out the...

    Get a professional to do the cabling. For the reasons mentioned above, plus it must meet the "code" of the country ,state, city.

    nearby radio station interferes with phone

    If she lives in a house (vs apartment), have her plug her phone into the jack inside the "NID" - the (usually) gray box on the side of her house where the phone line is "dropped." If she still hears radio, call the phone company, it's their problem. If she doesn't hear the radio, then her inside...

    Patch Cable using phone line

    It takes at least two pair (four wires). That, theoretically, could give you 10BaseT using commonly available SOHO equipment. HPNA could probably give you more, if you could find it. Six conductors will only help if there are protocols that support it. There aren't to the best of my...

    Advice to bypass Uverse for Wireless

    Plug in the LAN port of the router into the LAN port of the RG (3800 or 3801). You do not use the WAN port of your router for anything. You DO NOT want to connect the extra router (which is really acting as an AP) into a switch that also has the STB or DVR plugged into it. The issues is that...

    Patch Cable using phone line

    Phone wire has no category rating. In addition, phone jacks are usually "daisy-chained" (strung from jack to jack instead of home runs to a central point). Also, most phone jacks are wired with less than four pair (two are common - red, green, yellow, black). 1. IF it works at all, it's going...

    Advice to bypass Uverse for Wireless

    If you connect RG LAN port to your router LAN port, disable DHCP, and disable (or not, depending on the location of both units), you've essentially turned your route into an access point. Since you'd be going LAN-to-LAN, NAT setting doesn't matter. You must use the U-verse DNS if you have...

    Capacitor discharge

    Try this RC time calculator. You'd want ~ 24 Ohms for the series resistor, as a current limiter, and ~50000mfd which should deliver voltage for a bit over a second. If you charge it to five volts, you'll get five volts (minus some small losses). Tweak the values to suit your need...

    Learning beginners networking in a college course, have some questions!

    IMO, you need to know it because it's the root of everything you will be doing in networking. It is how you will address, divide networks into subnetworks, filter stuff in, filter stuff out, filter who gets to do what and where. It's just not that hard, 0's & 1's. x^0, x^1,x^3 ... For the...

    USB to RS232

    RS232 is usually around 12V ... so even with a power supply, I don't think you'll get there. You might need to drive a DC-DC Converter, like this: http://www.mouser.com/ProductDetail/Cincon/EC4BU-05S15/?qs=sGAEpiMZZMtwaiKVUtQsNVSoLQhqwWsL8F2yh2iJV1I%3d If you're doing this at a board level...

    Ethernet Cable Quality.

    ....and you're much more likely (as a novice installer) to install the system within spec. Cat6 & 6a have very tight specs and would be extremely difficult for a novice to do properly. Failure to properly install will result in sub-optimal performance. Make sure all components are at the...

    Using own router with UVerse

    Typical would be for the three services to be delivered on three lambda (wavelengths), with one being "digital cable tv" on one, Internet and VoIP down on one, and Internet and VoIP up on the third. The data is usually delivered on a fast Ethernet port, the VoIP is delivered to an rj14 port...

    Question about CIDR notation and subnets

    While "legal," addresses ending in 255 or 0 are usually avoided by convention. There are folks (unfortunately) that will see those addresses and "correct" them ... they're the same folks that "fix" the subnet mask back to its "proper" 255.255.255.0 value. Addresses like that are on / were on...

It can also connect to a PC to store/recall...

    New Home - Pre-Wiring

    I agree with the above post, and would add that you can probably get a good discount if you have the cable pulled, but not terminated (which takes the most time, and if it's "Certified" takes even more time ... time is money, especially Union Time). Getting the conduit is a big help. At the...

    Using own router with UVerse

    For any of the U-verse services, you must use the AT&T supplied modem/gateway/RG. You can configure it such that wireless on the RG/Modem/Gateway is disabled, and put something behind it of your preference. You can also put it in "DMZ Plus" mode (for 3801 / 3800) which forwards all traffic to...

    All wireless devices keep losing connection suddenly.

    IMO, start by downloading and running "inSSIDer," it's a free app that'll show you a map of signals and some interferers. Find the least-used channel amongst channels 1, 6, or 11 and use that. What you describe could be interference or just a flaky AP/router or power supply (brick, cube...

    New laptops w/ Serial Port?

    IF you have a prolific-based serial dongle, try earlier drivers. There's one issue of drivers (July 2011, I think) that works with nearly everything running Win7. Newer / updated drivers have never worked on anything I've ever tried them on (radios, consoles, programmers, etc.

    How many 5ghz wifi (N) capable devices do you own?

    Laptops mostly. I also have a video distribution system, and some microcontroller-based things I made that do various tasks. I don't have any wireless repeaters or bridges of either flavor. I occasionally test some APs and routers in AP configuration, but I don't count those because they're...

    How many 5ghz wifi (N) capable devices do you own?

    I've got a dozen or so, thinking off the top of my head ... perhaps more. I keep the consumer electronics on 2.4, since that's native to them, and I put all other data stuff on 5GHz where the air is clear and the data runs wild like the wind ... ;-)

    CAT6 how pin numbers in RJ-45 connecter used to carry Data

    To be accurate, you'd ask for UTP (or STP, or S-UTP) that meets Category {whatever} rating. i.e., "Get me a box of UTP, try to get Cat5e rated if you can" It's just that, people being people, they have abbreviated the discussion. Comparable to "please get me a tissue, try to get...
