    Default Gateway Is Not Available (i know it's been brought up before)


    Hi all,

    I know this has come up a lot here and elsewhere but I haven't found a solution that works for me. Also, my problem seems a little different - while most people I've seen talk about this issue mention getting disconnected from the internet a few times a day, or when they reboot, to me that sounds like paradise because right now, I can't get five minutes before the internet gets cut off, sometimes closer to thirty seconds. i am seriously about to lose my mind.

    So, we have a cable modem with a new service provider. We also have a new wireless router, an Apple 802.11n Wi-Fi Hard Drive that also serves as a router. These two factors (service provider and router) changed simultaneously but I suspect the issue has more to do with the router.

    So the issue is the same as what many people have described - after a few minutes of browsing the web (if I'm lucky), I am no longer able to connect to the internet. I am still connected to the network but am unable to connect to the internet. I go to the troubleshooter in the Network and Sharing Center and it repairs the issue with the message "Default Gateway Is Not Available." Then I have internet again...for a few minutes, until it happens all over again. Disconnecting and reconnecting also works.

    I have a new (1 month old) Lenovo ThinkPad T410 and it connected to the internet fine prior to the new router/service provider.

    Here is what I have tried to solve the problem:

    - Uninstalled Lenovo ThinkVantage Access Control because I thought it might be interferring with Windows wireless management tool.
    - Disabled the firewall
    - Disabled all AV (I generally have Microsoft Security Essentiallys running, plus SuperAntiSpyware and MalwareBytes that don't provide active protection but that I use to occasionally scan.)
    - Disabled all non-MS software in msconfig
    - Manually set IP address under Wireless Connections settings (and then went back to automatic). I changed it to both what it said when I ran ipconfig and what I found suggested in several places: 192.168.0.50, subnet mask 255.255.255.0, default gateway 192.168.0.1, DNS the same...
    - Checked that the wireless driver was up to date (it was, details below)
    - Ran the Windows 7 Troubleshooter a zillion times
    - Deleted the network and recreated it (many times)
    - Turned off the Power Management option to allow the device to be shut off to save power (under Device Management)
    - Flushed the routing table in cmd

    The only thing that really seemed to make a difference was uninstalling the ThinkVantage software. That seemed to make the internet bounce back quicker after it cuts out, but other than that, nothing has changed the situation. Also, the problem seemed to occur less often when I rebooted in Safe Mode, but it still occurred and and it's hard to say for sure if it was left often since the interval is irregular anyway.

    I am unable to ping the given default gateway (ipconfig below - 10.0.1.1)

    Macs and Vista machines are working fine on the network, so I do think it's something to do with Windows 7 and the new router.

    Please help, I am going insane having to reset my connection every 30 seconds.

    Under "Wireless Network Connection Properties" it says

    Connect using: 11b/g/n Wireless LAN Mini-PCI Express Adapter II

    When I click on "Configure", it gives the following driver information:

    Also, back under properties, it says

    "This connection uses the following items:
    Client for Microsoft Networks
    QoS Packet Scheduler

    Internet Protocol Version 6 (TCP/IPv6)
    Internet Protocol Version 4 (TCP/IPv4)
    Link-Layer Topology Discovery Mapper I/O Driver
    Link-Layer Topology Discovery Responder"

    I have not tried uninstalling or reinstalling any of those or the Realtek driver because I'm un clear on how to do reinstall.

    I am not good with computers (as is probably abundantly obvious) so please talk to me like you'd talk to your grandmother when it comes to computer stuff. Seriously, I suck at this.

    Thanks so much guys :)

    Hi ehat welcome to the forums,

    First of all, thank you so much for such a detailed explanation, it really goes a long way towards helping us help you.

    I am a little bit confused by this bit:
    - Manually set IP address under Wireless Connections settings (and then went back to automatic). I changed it to both what it said when I ran ipconfig and what I found suggested in several places: 192.168.0.50, subnet mask 255.255.255.0, default gateway 192.168.0.1, DNS the same...
    Was your gateway (router) at 10.0.1.1 originally, or have you now changed it to 192.168.0.1?

    If the latter, how have you changed it, in Windows, or in the router?

    Secondly, if you haven't changed the router settings, when the connection IS working, are you able to log into the router at 10.0.1.1? (May be 1.0.11 as you typed, but I suspect that was a typo)

    Hi Martin,

    So like I said, my grasp on computers is weak at best. And yeah, that was a typo, definitely 10.0.1.1.

    So basically this - when I first ran ipconfig, it said the default gateway was 10.0.1.1. I went to "View Network Connections" (from Start) and right clicked on the wireless and selected "Properties." There, I double-clicked IPv4 and changed the settings from "Obtain an IP address automatically" to "Use the following IP address" and then tried two different configurations. One was the generic 192.168.0.1 - did not work. The other was using the info I'd got from ipconfig - the default gateway 10.0.1.1. That did not solve the problem either. Then I changed it back to automatic.

    I don't know what the purpose of that experiment was, it was just stabbing in the dark. So if it sounds nonsensical, it might just be nonsensical.

    Hi,

    What happens when you open your Internet browser and type 192.168.0.1 into the address bar?

    or to actually answer your question (having reread it) 10.0.1.1 is the original gateway, that seems to be what it's using when the connection is working. It also seems to be the "default gateway" in question when it's not working. Which almost sounds like the router signal is flickering, but it doesn't disconnect me from the local network and the signal always appears very strong.

    Makes perfect sense... in fact you were fiddling in the wrong place, best case you would have seen no improvement, worst case you could have lost your connection altogether.

    At this point I was going to recommend you download a little diagnostic program, but it looks like it doesnt work with your router.... so we'll have to do this the hard way.

    Please log in to your router by typing 10.0.1.1 into your web browser, find the page that says WAN status or Internet Status, or something similar. You'll know when you find it because it will say your Sync Speed (may be Connection Speed) and your SNR on it, please upload a screenshot of this screen both when the connection is working, and when it isn't.

    I have a feeling I know what's wrong, and I also have a feeling it's an external problem, but I want to make sure.

    Not able to log into the router by putting 10.0.1.1 into the address bar (neither on the computer with the problem nor on my other computer). my roommate set the router up.

    also, i have no doubt i was fiddling in the wrong place. i did lose the connection altogether a few times, but managed to undo

    When you say you can't log in, do you mean it's asking for a password that you don't know? Or is it just refusing the connection?
