i am using dell inspiron 5520 for past 1 year recently i updated it to windows 8.1 i kept using internet connection for some amount of time it gets disconnected suddenly when i troubleshoot it connects and then fr same amount of time it keeps repeating although i have faced this kind of problem in windows 8 but in here it is most frequent
it could be a software problem or a hardware problem.
1)is it happening with other computers(or mobiles) connected to ur network?
2) How is the Signal strength?
3)did you try to reboot the computer?
4)Uninstall and install windows 8 compatible driver for your wifi hardware?
