Unplug/replug in router to connect

Last response: in Wireless Networking

May 21, 2012 1:19:45 AM

Just bought an HP dv7t-6c60us win7 Home.
About 1-2 weeks in, started getting connectivity issues, where the network's detected but I am unable to connect. Daily disconnects, sometimes twice a day. Renew/release IP doesn't work, says media is disconnected, and flushing dns, resetting winsock, ipv4, ipv6 doesn't work (even after reset).
The only thing that works is an unplug/replug of the power cord on the wireless router. This affects ONLY my laptop. All other wired connections and wireless connections are fine. Unaffected. Still working.
Turning off bluetooth and ethernet on my laptop yielded nothing. I changed out the router to three different routers, and got either the same problem, or a reduction of network speed, from normal 54Mbps to 1Mbps, even if I am sitting in front of the router (this seems to be a secondary issue that's cropped up, dependent on a type of router).

What's going on here? I've updated firmware, wireless drivers, etc, what I consider the normal troubleshooting fixes. I requested HP to send me a new wireless card, and the same problem is occurring. I have Panda antivirus right now, but this problem started before Panda. No windows firewall either. But it's only my laptop, and after the ROUTER is rebooted, my laptop can connect again. If I restart my laptop, nothing happens, still cannot connect to the router.

The only thing that seemed to work was changing to a USB wireless adapter, didn't disconnect after one day. Why is this working (ie laptop is maintaining connection longer than 24 hours) and not my normal wireless card?

Can there be something specific to win7 and the wireless card?


Also I just started getting my diagnostics, and it showed this:
windows couldn't automatically bind the ip protocol stack to the network adapter

Upon saving the diagnostics, I have this:

For some reason your machine is not authenticating with your router. Try switching your router from WPA2-PSK to WPA and see if that clears up the issue. I think your network card is having a problem with the WPA2-PSK protocol. In the log you posted your drivers are out of date compared with the ones I looked up for your card on Intel's site. You could try that too unless you already did that. Also you could check for a firmware update for your router too.

I did firmware updates and did upgrade to 15 for the intel driver for my wireless. How do I disable Ip6, from the properties of the card? The router is only about 1.5 years old, and it has no trouble with wpa2 with the other laptops (both old and new).

I was thinking that the card was the one having the issues with WPA2, if it works on WPA then that would be a good indicator.

The same issue is still cropping up. When it happened, I even rebooted into network safe mode to see if I could connect, to no avail. Of course, by unplugging the router, voila I'm back on.
If this card is pretty new, you think WPA2 is the issue? What if it's HP defect on the model? What if it's the intel centrino 1030 defect? What if it's my particular unit that's having issues?

You could try turning off IP6 like Emerald suggested. I re read your OP and you said that you have already tried a new card with the same issues? Are the other machines that are working fine running windows 7 as well?

Yes, all other machines run fine. I have also tried using a different router and that seemed to just give all sorts of other issues, like my laptop running at 1 Mbps after maybe a half hour of normal 57-73 Mbps, from my current location and even right next to the route. How do I turn off the IP6?

Thanks. But no cigar. Did it yesterday, today still disconnected almost 24 hours later. I had to reboot the router via unplugging it.
I had previously changed the DHCP renewal on the router to a longer time frame, but the problem still occurred. It's also strange that the other laptops don't get this problem when DHCP renews itself, only mine. I only suspect the DHCP because it's happening every 24 hours, and 24 hours is the default renewal on most standard routers.

Do as Hawkeye suggested (if you haven't already) go to intel and run the hardware scan to check for new drivers. I had the same problem on my HP Elitebook 2530p with Intel wireless 5100 AGN NIC. The problem persisted for a while, but after a couple of driver updates it stopped.
One other thing I could suggest is to try setting your router to use a different security setting, it looks like the issue may be comming from there. Enter your router setup and turn off the security setting completely. Then connect your pc and see if the problem persists, if the disconnections stop, at least you know where the problem is. You can then do a few tests using varios settings on the router until you find one that works without disabling the security all together.

I will try the wpa as well as unsecured for 24+ hours, but won't that just make my wireless that much less secure?

Also, I have updated to most recent intel. Didn't work.

If its DHCP causing the problem why don't you just give the machine a static IP?

Can you check your event viewer when you get a disconnect? Running out of ideas but the info in there might help figure out what is causing a lapse when the DHCP renews.

Also can you do an ipconfig /all in your command prompt and see if you have a ton of tunnel adapters. You might have to clear those out as well.

This is both event viewers. Netwns64 has trouble (event ID from source netwns64 cannot be found) during the times where I'm disconnected. Once I've unplugged the router, everything's dandy. Event ID 7036 also stops (it's the TCP/IP netbios helper) after starting during the times where I'm disconnected. Onnce I've unplugged the router and re-connected, the event 7036 starts, but doesn't stop.

I haven't been able to pin the exact time to the second on what comes first.

Did that, what's it do? I think so far I've skipped one day's worth of disconnects.

However today, I was connected to my router (had valid IP), pinging both router and modem was returning 1ms. BUT could not connect via IE/chrome, nor could I ping www.google.com. What's up with that? Managed to fix it after flushing/registering dns, reseting winsock, ipv4 interface and release/renew of ip. iTouch right next to me could connect to safari however. Seemed kind of strange.

I do have an update....

I have been noticing that whenever I am "kicked off" the network, IE unable to connect back no matter what I do with my laptop (renew/release/diagnose/disable/reboot), I found that my brother's laptop has just turned on and signed onto the network.

Two things work:
If I reboot into Linux, I can get on the wireless, and if I immediately reboot back into win7, still same issue crops up: unable to get onto the network (I can view it and try all I want).
If I unplug the router and let it power back on, my laptop can sign back onto the network, while my brother's laptop is on the wireless. However, there are a few times that the router will still kick me back off.

This leads me to conclude: something on my win7 and my brother's win7 is interfering with one another, especially at the level of the router. This is due to the linux side still functioning, and the coincidental times when his laptop is turned on just as I am knocked off.

Any thoughts?

I was having the same problem on my laptop and the only computer on the network with that problem. If you right click your network and select properties or get to properties however you want to, go to the connection tab and click the checkbox connect even if the network is not broadcasting its name (SSID). It for whatever reason fixed my problem.

i had a similar problem. everytime i rebooted my windows 7 laptop the wireless network did not connect, i had to restart my router and then everything would work. this started happening after a friend logged onto my network with a UK ipad, ever since then this problem has happened.
But this seems to have solved my problem (worked first time around anyway) thanks! I will post again if things break!
