This is the problem I had and this is the solution that works. I am using Windows 7 on a Dell Inspiron. I have the Intel Centrino Wireless N1050 driver.
Problem: After a hibernate/standby operation the My Intel Wifi technology used to get disabled. It won't get enabled even after you go to its menu and Enable it. It was annoying because rebooting was my only option.
The following solutions worked. One is easier than the other, and I am now using the easier solution. Both of these WORK!
1) Go to the Device Manager (Control Panel -> System and Security -> Device Manager). Expand the "Network adapters" option. You should see the following: a wireless adapter (in my case it was Intel Centrino Wireless N1050) and two Microsoft Virtual Miniport Adapters. I disabled the Microsoft adapters one by one. Then I disabled the Wireless adapter. Once this was done, I enabled them one by one - first the Wireless adapter, and then the Microsoft adapters. Once this was done, I let my wifi reconnect. Then I went to the Intel my Wifi utility window and enabled it. Now it stayed enabled. But unfortunately only till my next hibernate. So I followed the second solution.
2) I found this within Microsoft:
And it has worked! Don't forget to manually enable Intel my wifi utility once this is done.
I have the same problem, but it's very recent. It started the past.. month or so. When I first got the laptop back in December everything worked fine, but, like I said, for some reason it has stopped working the past month or so. Sometimes my laptop can connect to the wireless internet but it is very slow and typically gets only 1 to 6 mbps. Other times, it won't even connect and I get the wifi adapter error message. I have another laptop that connects to the wireless just fine. Any ideas?
Seems for the toshiba guys you have to go through extra installation steps: Intel� Wireless Display — Notebook and Ultrabook� system software and drivers for Intel� Wireless Display bullet #5
William Gustafson had also a problem a detecting his widi receiver Re: Dell XPS 17 64 bit Windows 8 WiDi Scan Does not Detect Belkin Screencast
His solution was linked to problem of the auto-detection tool offering drivers not compatible for computers with chipset series 5. I don't know if it could be that reason for this thread but in case... just sharing the info
i had the very same problem and what i noticed from the various post that latest update of window 7 is the main cause for this problem so i simply restored my computer to the previous month date n blocked the auto update for windows. result ..problem solved..its working fine now without any problem...so try to restore ur system to the previous date n keep enjoying hope one day when windows n intel will confirm having solved the problem with update we can unblock our updates..
I'm not sure if you resolved this or not. I had the same issue. Windows (or Intel) asked for an update so I did it. After it was done, there was no internet - it would not connect to anything.
I went to control panel and uninstall a program option. I found the Intel Wireless Proset wifi software line and double clicked on it. There was an option for Repair, Uninstall. I clicked on repair and after a few minutes, it asked me to reboot. After reboot, everything was working again.
Hope this helps!
Thankyou, Thankyou, Thankyou! I received a windows 7 update which somehow shut down my network adapter, I tried everything. I did 2 system restores, Spent 90 dollars for some to tell me they dont know, and I spent hours on the internet till my eyes bleed lol, and nothing.........Until today my friend, I performed this easy process, and poof, it was working perfectly. THANYOU my friend, you rock!
We are currently investigating this issue. Please keep in mind the general solution for it was already posted by Ileanak at the very beginning of this thread; however, at this time you may install an updated driver version compatible for your respective adapter.
Due to the amount of scenarios and possible causes we appreciate any further information you all may provide regarding the circumstances of this issue like system model, adapter model, driver version, operating system version and such.
@Joe_intel - the requested information regarding many issues has been given by numerous users in the past. however, you guys have not fixed a single issue regarding:
1. cursor problem
2. repeatedly asking for security code
3. adapter not found - forcing you to reboot everytime
Seriously? whats the use of reporting more issues? I have an idea - please make the platform and driver open source and we will test and debug things ourselves! Even college kids could write better drivers than the Widi team.
I understand the inconvenience this issue may cause. Please accept our apologies.
We also have to understand some of the replies are old. Newer information may be needed as we have posted newer drivers recently. If the issue persists I would like to recommend the possibility to escalate the case with the computer manufacturer as an alternate route for a solution while we work on further updates.
Keep in mind Intel® WiDi compatible systems are advertised as such because the system must be validated by the computer manufacturer as WiDi ready or otherwise installing the required WiDi software may or may not work. It is for this reason that the required software comes preinstalled by the computer manufacturer.
pls note that I have a Toshiba and I am having same problem!!!! I use to share my internet and everything went ok a few days ago. however since yesterday everytime I open My Intel WFI Technoligy in order to enable and share my internet it does not work and this message is shown> "A supported INtel wireless network adapter was not found in this computer" Pls hel me solving this problem!!
