I am new to both linux and ubuntu And giving them a try . after installing ubuntu 13.10. the wireless seems to work just fine. Then the "software updater" showed that there is some updates. and so i click install and left it doing its thing.
Came back to it saying that i need to be connected to the internet (strange i though i was already connected to the internet) looked at the top the screen and see the wireless icon show an empty pie. so i click on it and my home network is no longer there. found it under "connect to hidden wi-fi network" and try to connect to them, but to no advail.
Went to System setting > Network. and it says it "out of range". (how could i be out of range when i am within arm reach of the router). so far having it tethered to my tablet is the only way i can get internet access to it (haven't tried plugging an ethernet cable into my computer though, so i don't know if that been effected or not)
Is there a way to fix this, can reinstall ubuntu 13.10 (and not click on "software updater) fix my issue? if yes, how and will it missed up the current one that is already installed and updated a bit. (beside reordering the boot order in the bios).
i also got ndiswrapper, but so far i can't even find it even to i have installed it from the software center.
If it helps my computer that contains Ubuntu 13.10 is Gigabyte BG-BXPi3-4010
wireless card is Realtek RTL8723AE
Please and Thank you
