My Dell Inspiron 1520 with windows vista laptop says it is connected to the wireless network showing ‘ problem with websites security certificates ‘ on all websites and won't access any webpages. Why. Please help. Thanks
Well i joined the community late so couldn't reply on time. :-) This usually happens when the system date and time are off.
If your laptop is still running Windows Vista, there’s a good chance the clock isn’t syncing properly anymore, and that can cause certificate errors on almost every site.
Try checking the date/time and set it manually to the correct current date, then restart the browser and see if that fixes it.
If that doesn’t work, it could also be because Vista is no longer supported, so newer security certificates aren’t recognized properly.
