Slow Internet Connections, Dropped VPNs on Dell PCs (and others): De-install SmartByte

After several service calls, I finally found the root cause of my slow WiFi and Ethernet speeds on my Xfinity service.  Check your Windows applications (Windows Key plus q on Win10) and see if SmartByte has been installed. This piece of software will interfere with your connection's peak speed, drop your VPN connections and cause other issues.  You can disable it or remove it completely.    It is supposed to help prioritize applications and their demands for bandwidth, but instead just messes up everything.

 

It is installed on all Dell PCs and laptops by default for the last several years.  So, if you have Dell Update turned on it will REINSTALL SmartBytes, so your problems will reappear. 

 

I'm hopeful that the Comcast technicians can be alerted somehow.
