Gang,
Received the notice via Windows Update on my Aspire E5-573G that Windows 10 was ready, so I upgraded. Upgrade went smoothly, with no errors issued. Following the upgrade I went online to check my email at Google and followed a few links from emails to various sites around the web. I noticed I was having trouble connecting to some sites, but I was streaming a ball game on a Roku and two other people in the house were online at the same time, so I attributed the connection failures to bandwidth demand.
The next morning I got up early, booted up the system and went online. Had all the same problems of the night before: some sites loaded fine, but others would not load at all (Feedly, my local newspaper, etc.). I thought maybe the problem was the new Edge browser, so I downloaded Chrome. Chrome had the same problem: some sites load while others do not (the same sites). Had the same problem with Microsoft Internet Explorer. I tried updating my machine's BIOS to the latest available from Acer, and tried uninstalling/reinstalling the WiFi drivers, none of which fixed the problem. The only thing I didn't try was a wired connection (a wired connnection on a laptop sorta defeats the purpose).
Opened a chat window with Acer support (had to use my tablet since my laptop would not open that page), but was unable to find a solution--I don't think the support person really understood the nature of the problem. Eventually downgraded the computer back to Windows 8.1 and the problem disappeared.
Anyone else have this problem? If so, did you find a solution? If not, does anyone maybe have an idea what may be causing it?
