wireless card stop working randomly

My wireless card in my laptop (ASUS u46s) suddenly stop working randomly,
It randomly run smoothly or stop working completely. Yesterday I was running fine all day without any problem. Today it stopped to work after 5 minutes.

I tried to restore my computer, uninstall wireless driver in the devices manager but it just refuse to work.
And sometime my laptop can not event detect the wireless card (I scanned for hardware changes after remove the wireless card driver in devices manager but nothing show up until I restart the machine)

It's ,however, functioning without any issues when I boot in Ubuntu (so far at least ).

This not the first time this laptop has such issues. Last year the wireless card malfunctioned (in both windows 7 and Ubuntu) so I had to buy a new mini pci wireless card (intel N6300 AGN) and it had been working really well until 3 days ago.

I am unsure if this is another hardware problem or just a case of bad driver.

This is before I uninstall the driver




the wireless card not show up after that although I had scanned for hardware change.

Hello and welcome bigday mate sounds like you have another bad card my friend. It might be just a matter of taking it out and putting it straight back in - just a dodgy connection perhaps?

There seems to be quite a list of wifi adaptors there when the Asus site lists only the Intel one in the specs so to check just what there is in the machine you can try this

Using HW Info general components

Download HW Info andpick the right bit version - HWiNFO, HWiNFO32/64 - Download -(copy and paste this site into the search bar) If you do not need the runninginformation in the smaller right hand panel close it. In the left hand windowclick on the + for the individual device groupings and they will open out tothe various components.

Go on opening out furtheruntil you get to the device itself. click on it and it will highlight. In theright hand window there will be a very detailed description of that device asin brand, speeds model number etc etc These are very detailed and are just whatis needed for searching for drivers etc.

See my pic for anexample - in this I have opened out one my components and then highlighted one of the one you need andyou can see the detail.
The pic is of what is in my network adaptors yours might look different.

Ok mate well like they say if it isn't broken don't try mending it. This could have been nothing more than a simple glitch or we can hope so.

Just out of curiosity though could you post a pic of that Realtek highlighted so we can see the details on the right please?

Now perhaps I am not getting something here but just what is that card it mentions something about USB?? in that pic you sent me.
I ask because I do not know of any Realtek product that is a USB one the only references I can find is this https://wiki.debian.org/rtl819x and I am under the impression that it should be a dedicated chip on the motherboard.

The Realtek site gives me tis for the driver for that adaptor you have Realtek

Now the only other suggestion would be to use a wifi / USB dongle type like this
Netgear A6200 Dual Band Wifi USB Adapter A6200 | WiFi Adapters | Networking | Home | NETGEAR there are other brands of course like D-Link etc and I don't know if these will even be of any help.
I do know a member who is a bit of a boffin with networking problems although I think she works more with the actual set up ie modem / router / machine etc etc

See what you think of these options and let me know. I do feel sorry for you because I find networking stuff is so frustrating in your situation as I have been there done that

Sorry late reply mate now have you tried Zoe's suggestion and did it solve the problem? If not I shall pass it onto someone I know who is good with this stuff.
