Ubuntu Linux on WSL will not use Internet

I have asked for the last 3 weeks for help from Ubuntu for the Ubuntu app in the store. My desktop has no issues using the Internet no matter where I go. However, for the last approximately 4 weeks the Ubuntu WSL will not access the Internet at
all. Using apt-get update/upgrade, wget, curl, anything simply comes back as "Unable to access <whatever> site. Please try later." I have checked hosts, host.allow, host.deny, all are empty except for the normal comments. I have deleted/reinstalled
Ubuntu, deleted/turned off WSL/rebooted/used disk cleanup/turned on WSL/rebooted/reinstalled Ubuntu and nothing helps. Please, someone help me with this issue before I delete windows entirely and set it up as SUSE or Fedora only. Thank you
for any help/clues you can give me because Canonical doesn't seem to care.
