I checked and I don't think my router supports the 5ghz. There is nothing in the setup that has 5ghz. Yes, my internet and wireless card are working fine.
Rebooting with the router unplugged did not work.
The intel my wifi is not enabled. It is greyed out. I can't turn it on because it can't find the adapter. Or that is what I think is the problem.
Mike thanks for the help. On the toshiba board lots are having issues similar to mine.
A windows update broke my wireless display (adapter not found error) a few days after I got my Toshiba 3 months ago. As it takes so long for me to reconfigure my machine for work, restoring to factory was not an option so I just posted in this forum and left it broke, taking whacks at it here and there. Eventually however I came across a wierd network symtop (detailed below) that required me to restore to factory OS, wireless display now works fine. I will try to allow windows update in groups at a time, and post when/if I find the one that broke it for me.
Standard 192.168.x.x/24 network with 10 hardwired machines, 2 wireless machines (N). Can connect my Toshiba (with the adapter not found issue) to LAN all day, no problems. When I connct wirelessly all machines lose connectivity to thier DNS server(s) (ISP) for 30 seconds, then regain it again UNTIL I DOWNLOAD from the internet! Not kidding, validated this with diag tools on the other machines monitoring connectivity and even capturing network traffic. After regaining connectivity they will lose it again (my Toshiba experiences this at the same time) as soon as I download anything (FTP/HTTP/any browser). They DO NOT lose LAN connectivity, or have any IPCONFIG changed. They ARE NOT being flooded with packets, and I can see no observable in their TCP/IP stack or any other network protocol or config. I have repeated this test at least 50 times, changing every possible setting in the wireless setting;
Through windows I removed IPv6, Link-Layer Topology Mapper I/O Driver, etc...everything except Client for MS networks, ipv4 and client for ms networks. I've disabled / enabled Intel Connection Settings and changed every setting there... forcing 2.4g/5g, etc. Tried A B G N.
I've changed every setting under the adapter (Intel Centrino Advanced-N 6200 AGN Properties) - too many to list but I swear I've tried them all.
I've replaced the router, modem and WAP SEVERAL times, and changed MTU size and every other conceivable setting.
The only thing I didn't look into was the TCP/IP settings in windows that are only settable through the registry.
Again, ALL PC's on the network lose their connectivity to the ISP's DNS server and default gateway (ISP's not the router) as soon as I download anything over a couple hundred kb.
After a factory restore (wireless display works fine now) I still have the same issue above. Tonight I realized that the wireless mouse I was using wasn't bluetooth, but 2.4g RF (microsoft 4000 series). I will try tomorrow to see if that has any effect.
Update with additional information - I ran a system diagnostics on my dell studio and found that the following to services are stopped, and I cannot get them running. I will add all information my diagnostic test provides:
Display Name: Intel(R) PROSet/Wireless Event Log
Exit Code: 1067
Service Name: EvtEng
Path: C:\Program Files\Intel\WiFi\bin\EvtEng.exe
Service Code: 0
Started: False
State: Stopped
Display Name: Wireless PAN DHCP Server
Exit Code: 1067
Service name: MyWiFiDHCPDNS
Path: C:\Program Files\Intel\WiFi\bin\PanDhcpDns.exe
Service Code: 0
Started: False
State: Stopped
I opened my Task Manager and tried to restart both services, but am not able to. I keep getting a message stating that Windows could not start the service with the following Error Code: 1067 The process terminated unexpectedly.
Have you tried starting them in Safe Mode. Log on to Safe mode, search for services.msc and look for those services. Try putting it in Automatic and restart.
Just tried to start those services in safe mode - no go - they still would not start. I booted in safe mode, found the services, made sure they were in automatic (which they already were), and tried to start them. Got the same error message as before. Rebooted in regular mode and tried again - same result - would not start.
I checked the dependencies of the event service and found they were not started. I changed the service to allow it to interact with local computer, started the dependent services and was able to get the event service running, but kept getting a windows error message - so I set everything back to where it was.
I have the Wireless PAN DHCP Server service set to Manual. The other one is set to Automatic. How about disabling them in Safe mode, boot in Normal mode with both disabled and try starting them. If it doesn't work, go back to safe mode and set them as I have them. Manual and Automatic.
I tried both ways and still no change. I still get the same error messages when trying to start the services - and Intel Wireless Display still provides same message that Intel WiFi Technology is not enabled, and Intel My WiFi Technology says adaptor not found and all options are greyed out.
This is really weird. I have the same laptop as you do (Dell Studio 1569) and I only have that problem if I close the lid making it go into sleep mode. When I open the lid again I get the Adapter not found message.
And I'm at a total loss of what to do with it. I've tried practically everything at this point, and the WiDi display was actually what convinced me to buy this laptop. It was a great tool when it was working. And unfortunately, wiping the hard drive and re-installing OEM software is not an option at this point. I'd welcome any other trouble shooting suggestions.
Try uninstallin Microsoft Virtual WiFi Miniport Adapter #4 (or the one with the yellow triangle on it) under Network adapter in Device manager and reboot.
That's one of the inexplicable issues I've found - it is reported as working correctly under Device Manager. Nonetheless, I've already removed and reinstalled it so many times it's now up to #18. I did that when removing and reinstalling the updated driver and software for the wireless display; reinstalling the original driver and software; and with several variations. Didn't work.
bghauck - if you are able to get this fixed, you will be the first to do so without a factory restore. There are so many possible factors this is going to take a systematic, digressive troubleshooting. (All of the adapters being enabled and apparently working fine also baffled me).
Can you make an image of your entire system as it is, restore to factory, then send both to intel for analysis? It took me more than a week to install and configure everything I needed for my machine after a factory restore (including "anytime upgrade to Win7pro, XP virtual machine install, 100gig of programs and scripts that can't be just restored but must be fresh-installed and setup), but as of today it has worked fine since. Hopefully I will catch whatever breaks it (I'm assuming it will again) so I can help others here figure out what may be wrong with theirs.
This is an issue with one of the windows updates and the driver. Nothing we can do about it. I have no clue which update hosed it and I am not doing a factory restore. I will just live without the mifi. I am returning the netgear part to best buy.
Sorry, I don't have the capability to make a current image of my system, reinstall OEM software, make another image and send both to Intel. Would it make any difference if I removed the WiDi driver/software and re-installed them in safe mode?
You have a different PC, OS and config so it's impossible to say... but it didn't with mine, and would say maybe 20% chance that would work.
