Broadband connection problems

Discussion in 'Windows Vista Networking' started by zipdogso, Nov 3, 2008.

  1. I'm the "Someone" who you quoted. I'm sorry that you're having
    trouble with Vista, and I'd like to help.

    My answer that you quoted applies specifically to connecting a Vista
    computer directly to a cable modem. If your seven techs can tell me
    what setting Vista has that's different than XP's for connecting
    directly to a cable modem, I'll gladly look into it. Until someone
    can say exactly what's different, I stand by what I said.

    Your problem is different than that, since you say that you're using a
    router. Let's start with the problem of losing all the devices.
    Please describe exactly what happens, and we can start by
    troubleshooting that.

    Zipdogso,
    When you use a command prompt and run ipconfig /all what information
    is returned? What I'm thinking is the Vista machine is not getting
    the proper DNS or gateway server IP's to function properly. Once you
    have confirmed the data is correct, you could try a simple ping to
    something simple like Yahoo.com. If that fails try pinging the
    gateway IP or one of the DNS IP's. I am guessing you may have already
    tried this, but if you could post the details here it might help in
    understanding the nature of the problem.

    If you can't ping Yahoo but can ping a DNS IP or gateway IP, try
    pinging 206.190.60.37 (a Yahoo server). If that works then maybe your
    DNS service is not working. If it's not, then hopefully someone else
    here will know how to confirm the Vista DNS is working properly--I
    don't have that much experience with Vista--especially the 64 bit
    version.

    Let us know what your results are.

    Thanks for being civil--I'm not as computer savvy as many on these boards, but I know I'm in a world of hurt and if you're serious, I'll do my best to explain my problem. I don't know what the setting is that makes Vista do what it does now. I don't know why it started playing pranks on me four weeks ago after years of perfect Net connections including WITH Vista. But I know I'm not alone because after having all those techs throw their hands up in despair, I've been checking boards and talking to people who have had the same experience all over the place. This is not a one-time issue. It's a big issue with countless threads devoted to it all over the Net. I've visited as many as I can, and only one person, so far, has had his problem resolved. His solution didn't work for me.

    So if you could help me with the problems I'm having I'd be delighted. One reason I haven't been able to answer you 'til now is that my Net connection has been going on and off for the past two hours at will. I'm not going to address what happens when the devices don't show up--that's not my biggest issue unless that will explain why all this is happening. But the techs didn't thinks so, apparently. My biggest issue as an online instructor who has to use the Net for her job, is having Vista decide, at will, to connect to multiple networks, or not to connect to anything...and then once I do get a connection, to lose the Internet every few minutes all day long.

    Let me try to explain. I have a wireless network, but the big mother ship PC is connected via the Ethernet connection. We disconnected the wireless connection one Sunday when a Comcast tech decided it was causing the "IP conflict" message I still get sometimes. Still, it tries to connect to the wireless one constantly even when I disconnect it After I disconnect the wireless connection, it may work for a short while. Then, the blue globe disappears, and the fun begins.

    What I do then, having learned that disconnecting the router won't make any difference...is to play with the "Diagnose and Repair" messages. I no longer do what they say. I choose from the three or four options randomly, 'til one works, and I've learned that any one of them will work eventually, after a few rounds. Usually, resetting does it. But it can be "any of the above," really. There's no rhyme or reason to it. Three Comcast techs stood in front of my PC watching me do this. And then watching the little globe disappear, then the pop up message change every few minutes from "Local and Internet" to "Local only" and back again. Then...one of them went to watch the same thing happen with my laptop, which is newer, and also a Vista machine. Meanwhile, I brought in my daughter's Mac...and it worked beautifully, the whole time all this was going on. We could see that the router was fine--all systems go, all lights on. We could see that the Mac never lost its connection. But my two Vista computers were constantly losing and regaining their connections. Or...not. Until I went and played "troubleshooter Roulette" for awhile.

    They dug up cables. They replaced cables. They did things they really didn't need to do, hoping they might help. But it always came back to Vista doing that little dance back and forth again and me having to dance with it 'til it decides to let me back on. So I am literally having to stop, in the middle of grading work for my online classes, every fifteen minutes or so, to play a guessing game with Vista to find out what it wants this time. I don't want a Mac. I HAVE two perfectly good computers that I used to adore.

    Do you need more? If so...just say so. I'll try to comply if you really think you can help.

    Cynthia (or Zip?),
    I'm trying to "guess" how your various computers are connected, so I
    suspect we will need more data to be helpful. I'm guessing you have a
    standard Comcast modem connected to their incoming cable. From their,
    I will assume you have some sort of router (wireless?) connected so
    you can connect the various computers. Please verify this and if
    possible let us know the bradn and model number of the router. If you
    any other pieces of networking equipment connected let us know what
    they are and how they are connected. The reason we need to be pretty
    specific about model numbers and how things are connected is that it
    is quite easy to screw up a network by plugging something in that
    conflicts with other equipment.

    I'm going to post specific responses interspersed with your comments
    below, but set apart by asterisks like so--******MY COMMENT******.
    Please try to look at each one and respond if appropriate.

    Hopefully you are able to figure out waht I'm trying to get at so we
    can help.

    Thanks again, and let me explain how I'm connected first. I have a Netgear box (model number CG814WG v2) to which the big Presario PC is connected via the Ethernet connection. The cable from the wall goes into the Netgear...and the Presario is connected to that via the Ethernet cable. All of the other computers are wireless--and the Netgear box handles that, too. So everything is actually run out of the same little box now--so maybe it's not a "router," right?

    I also have a Vonage box connected which...doesn't ever to interfere with anything and is leaving us tomorrow when we bravely try to use all Comcast's telephone service just because they told me I'd get a better "box" when I switched. That means EVERYTHING will come from the same little box as of tomorrow, rendering a LOT of this moot, but I'm still going to post this in case it all goes as badly as I think it will.

    As for your questions...I did nothing new four weeks ago. That's what amazes me. I was working on a script and suddenly looked down and noticed that the Net had gone away. I've been playing "tag" with that little globe ever since. There were no new updates that day, either, in fact--I've had issues with updates, and can sometimes just go to a restore point to fix that. Not always, but this time...there wasn't anything like that going on.

    Second, the Net goes on and off only on the Presario PC and laptop running Vista. The Mac has no trouble at all as long as the Netgear is up and running, and since Comcast fixed the cables, etc., it's always totally on and the wireless signal work perfectly. When I reset the Netgear we have to begin again and enter the right code, but otherwise...no worries.

    "It" is the mothership Presario I use most, and it's connected solely to the Netgear box--there is only ONE box and that one box does it all. We've disabled the wireless connection to keep it from trying to connect to that all the time...but it does anyway. In fact I can see all the names of the connections we've used in a list when I click "manage wireless connections" and the Presario will just try to connect to any one of 'em on a bad day along WITH the Ethernet one. I'll run the arrow over the little globe and discover I'm connected two or three different ways. DESPITE having disabled the wireless connections several times. That, apparently, is where the weird IP address message comes from. Vista thinks there are all these different computers trying to connect even when others aren't on. And of course there's conflict--it's all the same machine trying to connect three or four different ways.

    As I say, we're going for the big one tomorrow and supposedly receiving a "far better" box that will do everything from phone to wireless network. I'm just desperate enough to try it. But this is what I have now. And despite the change...I'd love your feedback, if you now have enough to go on. We've done all the simpler "fixes" and futz'd around for hours playing with addresses and even disabling devices and bringing them back to see if that helps, so at this point I'm just curious to know what you think, even if everything changes tomorrow.

    Nothing has worked thus far and frankly, I'm scared about tomorrow's last ditch effort. While I was typing this, I lost the Net twice. But...not on the Mac of course. Arrrrrgh! If you want to wait, though...I'll understand...

    Since you are about to change a major piece of your network, I suggest
    you wait until Comcast puts in the new equipment. One word of
    advice---after they hook up the new Cable Modem/Router/Digital Voice
    box, have them test it with a wired connection only first--in fact, if
    they can, make sure the wireless section of the new box is completely
    shut down during the test. Also, whichever computer is used for the
    wired test should have it's wireless adapter disabled in Device
    Manager. Once you have confirmed a good connection with the wired
    side of things, you can move on to a more complex structure. One
    thing I would do (if it were me) is test each computer in a wired
    configuration, ensuring they all can connect while they are the only
    computer on the network. Then I wouold would move to the next step--
    connecting two computers in "wired mode" to make sure they work and
    then add the third computer if the others work. Once you have
    confirmed all computers work in the wired mode, you can then begin
    setting up the wireless network. Again, after you turn on the
    wireless section of the Comcast box, make sure it is completely set up
    (security, radio channel, SSID, etc) before trying the first computer
    wirelessly. Then try each computer wirelessly just like you did the
    wired test--i.e. one at a time with no other computers connected.
    Once you get all three playing nice wirelessly, you should be able to
    again use your network.

    Oh, and by the way, the worst thing you can do is use the Comcast CD
    software or any of the "wizards". If the Comcast guys can't show you
    how to do it manually, then they are either dumb or lazy--or both. No
    standard DSL or Cable Internet connection should require special
    software or wizards to configure--it takes a thoughtful human to make
    the proper choices to get a network working properly.

    Good Luck!!!

    After two days, again, of techs battling to give me both the Net AND Comcast digital phone service...things seem to be working well. I let a really wonderful Comcast tech just take over my office and work everything out after the Saturday tech gave up. A new router and EMTA and some magic Vista tricks that I still don't quite understand--and which seem to have become unnecessary once the "savvy" tech arrived--seem to have done the trick. I remain a wee bit skittish...but so far...so good. We'll see...but for now the case appears to be closed after some nail biting...

    I am having the same problems zipdogso and cyn have been having. M
    computer is relatively new, about 2 months old, and I am connecte
    directly to a modem which is about 6 months old. Up until last week m
    connection was fine. All the sudden I was getting random disconnects
    this is very annoying when online gaming ! ). Everything would shu
    down, MSN messenger, web surfing, email, etc. I would go to the Comman
    Prompt and there was no DNS suffix, although there was an IP address. M
    old XP computer never had these problems with the same ISP ( Shaw Cabl
    ) and I have been with this ISP for several years. Now with Vista, i
    has become very dodgy. The only thing that I do that seems to work i
    shut off the computer for a couple minutes then turn it back on agai
    and it seems to regain the DNS and I am online until it does it again..
    every time this happens it brings up some name / password connection bo
    which I just cancel as I don't require any sort of login to my ISP.
    I haven't contacted my ISP yet as I am thinking this is a Vista issue
    not an ISP one. I am pretty sure if I put my old XP box online that i
    won't behave like this.
    Also, my computer does all the automatic updates so I am wondering i
    this is a recent update or security issue. Nothing I do seems to trigge
    it, I could be gaming, sending an email, or surfing, it seems ver
    random
