This time I can say for certain that microwave oven activity is not the cause. Most of the day I have seen a 90% strength connection. As 8 hours uptime approached it suddenly dropped to 14%. I carried on working, including downloading and installing an rpm, for about half an hour. Then I went for my daily half-hour walk. When I came back the connection was lost and it could not connect again. The symptoms are identical to yesterday. Using system-config-services I saw that netfs was marked as dead. That suggested to me that it should be running, so I started it. netplugd is marked as disabled but running, as is network. To be on the safe side I restarted both. I also restarted NetworkManager. I'd appreciate comments and guidance on these and any other services that could be implicated. I am now going to power down the netbook and leave it until after dinner. I'll power it up again in about 1.5 hours. If it connects then I will suspect a component heat problem, although I can feel no heat worth calling from the case. Anne
