Overall, I'm happy with this Chromebook after using it for four days. The only problem is that the wifi connection has been getting worse and worse.
The Chromebook keeps dropping wifi signals. To troubleshoot the problem, I've connected with my laptop side by side with my Chromebook and the laptop has no connection problems with the same network. The Chromebook shows the wifi signal at around 48% when the laptop shows 100%. I disconnected wifi on my laptop in case there was some kind of interference and tried again with the Chromebook, but that didn't help. This Chromebook problem started a couple of days after I started using it and seems to be getting worse.
Web surfing is still possible on the Chromebook because the disconnections are sporadic. The main problem is that my VPN disconnects every time the signal strength drops. Again, my laptop has no problems with the same network, the same VPN (and the same VPN server) and the same location. Do I have a bad unit?
