2020-05-01 Probable lightning damage to an Intel E1000 networkcard 3 weeks ago
Today I noticed weird problems with the network in a desktop computer. It kept losing packets on the local network, with other computers in the same switch having no problems. In the end I switched to a different networkcard in the same computer to get rid of the problem. And that solved the problem. The most probable reason is a lightning storm that came very close yesterday evening.
