  1. are you sure the router is configured correctly?

    well i didn't change anything i just took it out of the box and plugged it in

    i have DSL d link should i change something in the configurations ?
  3. What model is the router? Does it support gigabit?

    Have you tried a different cable?

    d link n600
  5. That's not a model, that's a specification.

    d link dual brand VDSL n6850U
  7. I'm getting no hits on Google for it.

    Can you check that's the model, and possibly post a picture of the box or link to where you got it from?

    i went and bought new cable CAT 7 and still same problem nothing fixed
    i don't think its the d link problem i mean the internet company gave it to me once i upgraded my internet speed



    thank you for your help what else can i do?
  9. It's possible that it's disabled in the router configuration. If you look in there for terms like 'green mode' or 'fast ethernet' you might find it.

    I still can't find their page for it (looks like an OEM-only one). It's possible it doesn't support GbE.

    Is there any particular reason you need Gigabit?

    hey i found out now on the box its says x4 RJ 45 10/100 bas TX ethernet so i guess it don't support 1giga afterall

    if i add 1gig switch to this router will it work on 1 gig ?

    and i need 1 gigabyte because i am getting bottleneck i get only 89 mbps DL
  11. What's your internet speed supposed to be? You normally need to knock ~10% off the top for overhead etc.

    The link from the switch to the router would still only be 100Mb/s, so it wouldn't be any faster. WiFi might be faster though, as the bandwidth is significantly higher.

    100 mbps DL speed and i am getting only 89

    It's unusual to get more than ~90% of the download speed, even if on GbE. This is usually because of the overhead inherent in IP, TCP, and PPP.

    This is quite country-specific, but some parts of it will apply to you. I can't find many other useful references.
  14. Just too add this but you said that your router came from your ISP and honestly those are usually crap. what I would recommend doing is tell them you want a non router modem which will have only one Ethernet out and then plug that into a new router. It'll preform better but it is more expensive so you may not want to do that.
  15. With most ISPs I've seen it's take our modem/router or buy your own everything.

    That sucks I have ATT DSl and Charter at the old house gave us a choice what we wanted to get from them did have to specially request it though. I just figured that was how they all worked looks like I need to watch for that in the future now though.
  17. Cable is generally a lot harder to use your own modem for - they link it to the modem serial number, by memory. Plus a poor quality modem can trash the connection of others in the area, while DSL is a point-to-point link and has very minor effects on others. DSL modems are a lot more commoditised; you can pick them up from basically any store and they'll work.

    89 mbps download is pretty fast, especially for DSL which tends to be lower than cable or FIOS.

    You can use a 1 gig switch and hook up your computers to the switch to get 1 gig speeds between your computers, but the internet connection to the ISP won't be any faster.

    What speed service did you get?
  20. VDSL can hit 200Mb/s with vectoring and a bunch of other cool stuff. Only when really close to a DSLAM, though. Think sub 100m. Usually in a comms room in the basement.
