I am using a lenovo laptop and I just update to Windows 10 64 Bit, I was using Windows 8. I have had this problem when Windows 8 was installed and was hoping the update would solve the issue. Whenever I to use this laptop, I have to disable and enable the wifi adapter in order to access the internet. I stay connected to my router and there is no triangle on the wifi icon stating no internet access. This seems to happen after a certain period of time, even when I am using the laptop it seems. My Router is a Linksys E3000. No other devices on the network seem to have the issue. I do not know if this happens on other networks with this laptop or not, I have never tried. I also use a wifi extender. That seems to lose connectivity after time as well. I do not really know how often though and cannot provide and further information as far as the extender. That may be a seperate issue with the extender as it is a cheap one. If anyone can tell me what to look into so that I no longer need to keep resetting my adapter I would greatly appreciate it as it is very frustrating.
