I have an Asus U56E laptop running Windows 7 that I purchased last year. It is equipped with an Intel Centrino Wireless-N + WiMax 6150 wireless device. Recently I've begun to lose connection to my wireless router at random intervals while other computers on the network remain connected. The connection will report that it has limited connectivity. After disconnecting from the access point, the wireless device will not show any available connections. When I try to disable and re-enable the device in the network adapter settings or the device manager, the process hangs up indefinitely. On occasional boots, the device will show up in the device manager with a status of "This device cannot start (Code 10)". Also of note, the device seems to appear twice in the device manager, once as a generic "Network Controller" and once as "Intel Centrino Wireless N + WiMAX 6150". When I run driver installations, it is the former device which the drivers install as the Intel Centrino Wireless-N 6150.
So far I have tried reinstalling the device drivers using the latest drivers from the Intel site, as well as the drivers hosted by Asus on the page for my laptop. I've done this multiple times with no discernible results. I have also adjusted the Power Management setting to disallow windows from disabling the device to save power. I have also tried disabling 802.11n mode in the driver settings.
Any suggestions or solutions that worked on similar problems? I'm beginning to think the device may be broken and in need of replacement.
I also have the same problem on my u56e-BBL6 with the Intel Centrino Wimax/Wirless-N 6150 device. I've tried all that you have mentioned in the past month and still the wireless craps out very quickly, either as if the driver is not installed or the hardware/device itself is malfunctioning. This problem has slowly crept on me in the past 6 months. I remember having to re-install the driver about 6 months ago and then all seemed fine but it progressively got worse until this past December the driver would only stick for about an hour at most not online gaming, just for checking email, web browsing. Online gaming and the wireless would go within 5 minutes. I've re-imaged my computer multiple times and the problem has persisted to the point I cant even web browse through a wireless connection. I am using my Ethernet cable. After mentioning all this info to a Micro Center tech guy, he thought it would most definitely be a hardware issue relating to the stack. Hopefully Asus or Intel will replace this piece of hardware for me. A wireless adapter should most certainly last you more than 6 months to a year.
I am (and have been) having the same problem since Dec.29. The hours spent trying to figure it out have been enormous, as I thought it was a problem with internet, then wireless router, etc., etc. I was told by one tech. that when the wireless adapters quit working, they die a slow death. I am right now in the process of ordering a new one. If I go to the work of opening up the laptop (I have the SAME EXACT ONE you have - ASUS U56E) and it is loose or disconnected, great, but if not I want to have the right one to replace! Anyway - IF you haven't already figured this out - here is how you can get it to work TEMPORARILY until you replace it - REFER TO #7. ASUSTeK Computer Inc. -Support-
7. If wireless network adapter disappears from the device manager, please access BIOS by pressing < F2 > during boot up, press < F9 > to load the setup default, then press < F10 > save and restart.
This works for me, albiet sometimes I have to reboot a few times. There have also been new software/driver updates as of March 2013.
Hope this helps --
Oh! I forgot to mention (so did ASUS - ) but this is important! After accessing BIOS and loading the default setup F9/F10, go back to the device manager and select Network Adapters, then select 'Action' - 'Scan for Hardware Changes'. If the reboot worked, the adapter will show up. If not, do it again.
Thank you very much for posting.
It is not normal that the Intel® wireless adapter driver disappears completely, if that happens is most likely a hardware issue that you may want to solve with the computer manufacturer.
Edward, regarding your case, you may want to fully uninstall the driver from Programs and Features and Device Manager, restart, install the Intel® wireless driver and restart again. If this suggestion does not solve the issue then you may also try contacting the computer manufacturer as operating system corruption may be the cause.
