Laptop not receiving any wireless signal
« on: November 07, 2010, 01:06:08 AM »
Hey guys.
Today while browsing internet on one of my laptops, suddenly my network stopped responding
and a little yellow triangle on my wireless icon on taskbar popped up. Well It had happened before
and so I disabled the adapter, restarted the computer and enabled the adapter again. This used to work at all times.

Not this time. Now the wireless icon just has a red cross on it indicating no available wireless networks.
Lan is fine, wireless won't show up at all (can't detect wireless networks)

What I have already done is:
1) Resetted and re-configured my router
2) reinstalled and updated networking drivers
3) Changed wireless LAN card inside my laptop to see if it was the networking card malfunctioning
4) Even tried using external USB wireless network adapter (Netgear)

Results: Nothing solved the problem. I thought it might be internal wireless antennas that are broken
somehow but then how to explain that USB adapter won't find any wireless signal either?

Thanks in advance,
Sylv

Couple of things we can check. First if this is the laptop built in wireless make sure the wireless button on the laptop didn't get switched to off.

But you also said the USB adapter couldn't find any either.
If that is correct then it could be the windows wireless service isn't running for some reason.

What version of windows are you on?

Win 7 x86
Yep, wireless is switched on and indicator light is lit.

I haven't got a chance to see if it was the service problem but I did at least a dozen restarts
so if the service hasn't been disabled for some reason, it can't be the service. Will check it asap.

Also check the event viewer and see if windows has reported anything.

Okey here we are.
Sorry for the delay.

I didn't see anything wrong with the services. However I'm not even sure which service should I focus
at since there is no "wireless" service even listed. Just some networking ones (like netbios) , WLAN autoconfig and a service without  description, which has my WLAN adapter name. Those services are all running as intended.

In event viewer there were nothing listed as critical, however there were a bunch of errors reported by DHCP-Client event/admin. They were mainly the same error (2 different i believe) that had been reported constantly over time.
But I don't think that was the cause of the problem I'm experiencing as these errors have been logged since 2009 or  the beginning of 2010. However I attached the event log file (just remove the .txt extension to view, couldn't upload otherwise due to restricted file types)

Next thing. Network diagnostics troubleshooter report states that there MIGHT be an issue with the driver for the Wireless network adapter.

It outputs following error:
"Window's couldn't automatically bind the IP protocol stack to the network adapter"


Could it be registry issue in some way? I mean there is even no "wireless connection" listed in Windows Mobility Center and as far as I know, it clearly must be there. Should I format and reinstall windows??

I don't know... I'm getting so frustrated with this damn thing that I just might set it on fire soon.....

Thanks anyways
Sylv.

I know that telling a user to do a reinstall is the easy answer to give, and a TON of people tell others to reinstall when they don't have the answer.

But in this case it might not be a bad idea, because it is what I would do.

For my system I reinstall about once a year. Why? Because it normally needs it.

I install and uninstall so many programs, make so many changes, do so much to the operating system that it is a little battle worn over the course of a year. And there is always SOMETHING out of whack or not working like it used to or should. Like right now my Windows 7 x64, my ATI control panel no longer works, windows tells my daily its not genuine but it is, and when I go to system properties it sees it is and goes away, and a ton of other things I have spent hours researching, and none of the fixes work. So I am getting ready for my yearly reinstall.
I have spent hours doing all the tricks, fixes and updates. But the time it takes to track down every little reg key, file or the source of the problem, I could have just reinstalled and been done days ago! lol

And a reinstall gives me a fresh nice install, without all the crap files, registry entries and anything else left over from the flood of software, updates and drivers.

So in all honestly, if it has been a while since you did a fresh reinstall then it would be a good idea to do. :wink:

Well, I have the same habit to be honest. To do occasional reinstalls, for the same reasons you described Shane.

Few years ago I would've done a fresh install to solve most of the "bigger" problems that I couldn't understand but now I really spend hours, days and sometimes even longer, digging to the bottom of the grave trying to learn new things while asking questions and figuring problems myself.
But meh, actually it hasn't been more than 2-3 months since I swapped the crappy Vista with Win7 on that PC. Also considering that it's currently being used by VERY basic user with not even beginner skills who just browses internet without even downloading anything, the PC is as good as new so I just can't understand. Even my brother's Acer did better. It's clearly some random windows messup. But whatever.  I'm definitely tired of this particular case so I'm going to end this madness and put a fresh copy
of Win 7 on the machine.

Thanks anyways,
Feel free to close this thread!

The reason I am as good as I am with computers is because I refuse to give up. Every problem I encounter I refuse to give up on. You can also see this in my programming.

So after every problem I get just a little better. and after 15 years, it all adds up :-)

So keep doing the same and you will be a hell of a tech  :wink:
