hi all, not had my iMac long but just last week or so when i switch mac on it seems to take quite a while to start up, and not all the time but as i said more of late it go's to a log on screen and asks for me or a guest to log on i click on my name and as i don't have a password start up i don't enter one, but every time this happens when every thing has loaded up my internet wifi does not work ? i do a scan for a connection,but it never detects one, i usually have to switch mac of and back on for it to load up as normal. getting to be a bit of a pain mac only 3 months old .
any thoughts folks ?????
