Yellow)! need your help, megaminds Laptop : Medion akoya E7214 the thing: after (regular) automatic updating of windows10 WIFI controller stopped working. The hotkey Fn+F7, that has to enable WIFI connection, doesn’t respond at all, others hotkeys work properly. And internet by wire is also functioning. attempts to fix: i thought that the problem might by with drivers; so i got the new driver **Realtek RTL8192DE Wireless LAN 802.11N PCI-E NIC MAC0 ** version: 2019, tried to install it manually in Device Manager - Network adapters - Realtek ….. - Properties - Update Driver - picked a folder with downloaded - then system said my this :” Windows has determined that the best driver for this device is already installed. There may be better drivers on Windows update or on the device manufacturer’s website” end of quote. Current driver version is 2021.2.327.2013 very doubtful that this is the best. Installing drivers by specialized programs didn’t help ether ( DriverPack, DriverHub) What can be a solution (except buying a more modern laptop)? Thankyou! .
Hi @whitehole What is the status of the WLAN adapter in Device Manager > Network Adapters > right click WLAN adapter entry > Properties > General > Device Status? Does it say that “This device is working properly”? If so, try resetting the Network Stack from an Administrator Command Prompt window. Scroll down to the section:Resetting the network stack, in the link Update (09/18/2021) Hi @whitehole , Try using the laptop as close as possible to your WiFi router i.e. <25cm and check if you can detect your network. If you can then you have an antenna problem. Perhaps it is loose from the WLAN card. I couldn’t find a teardown video for your model but found one for a Akoya E6424 which may help. Here’s an image from the video showing the WLAN card (I think) and the black and white antenna cables going to it.
(click on image to enlarge) You can also try installing this free WiFi sniffer program to see the signal strength values of networks around you. Note: the signal strength values shown by the program are in -ve dBm values so the higher the -ve number the lower the actual strength of the signal. Also with dBm every 3dB is equivalent to halve or double the signal strength e.g. -70dBm is 0.5x the signal strength of -67dBm but is 2x the signal strength of -73dBm. Here’s a link that gives the range of values for WiFi signals and how it affects the connection.
Just uninstall in Device Manger and reboot. Drivers get corrupted from time to time and an uninstall is necessary. Video drivers being the worst. You could also try going to the MEDION web site: https://www.medion.com/gb/service/topic/… Let us know how it goes.
You can try checking the system files with a few utilities- perhaps something was borked during the update. From an administrative CMD prompt run: sfc /scannowwhen completed run: DISM /Online /Cleanup-Image /RestoreHealth (see https://www.windowscentral.com/how-use-d… for a good description of the options) then reboot if any repairs were made\noted.when completed, next run sfc /scannow again Another option may be to find the original drivers (like on the disk that comes with the machine) and try those as others have mentioned. You could even restore from a backup prior to the update install and see if the wifi works or not. There is a chance the wifi card itself is dead and the timing is just coincidence.Finally, here’s a link from others having a similar description of symptoms: https://answers.microsoft.com/en-us/wind… I hope something here helps! Best of luck.
@jayeff ive placed the router directly close to laptop, no changes appear. i think that problem more possible laying in software, because connection by Wifi doesn’t even want to turn on to find any possible wifi networks. the system just doesn’t want to turn it on, after clicking ,in settings or in networks panel, on wifi connection, the “turn on” position holds for few seconds and then just switching back to “turned off” (as on the images below)
on the second image its turned on but as soon as i refresh the page it changes back..
