Windows reports no Internet access, when there is

article #1283, updated 1702 days ago

This is usually reported by an alteration of the network mini-icon in the system tray; hover over it and it will claim there is no Internet access. The only solution I know of, is to go into the NIC, and turn off “IPv4 Checksum Offload” or something close. In most cases, this setting is on by default.
