Lately when computer woke up it connected to the printer instead of the modem. I had to select the network myself. Now it says it is connected to wifi but it says no connection. Have shut down several times with no luck. Other computers in the house work fine.

Hello,

Sounds like it is connecting to the wireless/wired networks, but there may be a setting in the Network preference pane that is blocking access to the Internet.

See if you are using DHCP, not using proxies, status of firewall on/off, etc.

Let us know if anything looks out of place,

I had a look in here and changed settings to see what would happen, no luck. I am picking up an outside network, not protected but I can't join that either. I have restored from an earlier backup but did not help.

Strange, I have been using Bluetooth & Hotspot, very slow. Came to Computer this morning and saw that there were updates from Apple waiting to be installed. They installed and computer restarted. Bingo, wifi back in action and faster than before!! Alls well that ends well. Thanks again.
