Intermittent problem with our PCs (NUCs and desktops with 1219-V NIC adaptor/drivers) where users see yellow triangle "no internet access" on system tray. Machine will actually still have internet access; but will experience problems like one user MS Outlook will receive email but won't download pictures. Other users have problems with IE11 based software. Can do network reset or ipconfig commands to fix; but can't stop it from happening in the first place. We also have HP laptops equipped with Intel 1219-LM NIC adaptor/drivers they do NOT have this problem. Anyone else? and if so any possible solutions?
