Hello, I'm hoping you can help with an issue I've been having since the turn of the year (roughly around the time I upgraded to Maverick). Basically my connection to my BT wifi (Home Hub 5) regularly drops out, usually when I use my iMac after a period of inactivity. I didn't have this problem prior to installing Maverick - currently on version 10.9.2. My iMac is late 2012. I don't know why this occurs at the start of almost every session, but it does. It doesn't tend to happen when I'm up and running and using the iMac. Sometimes I reconnect within seconds, sometimes it takes several minutes. I usually have to input my password, often several times over as it erroneously claims that I have inputted an "invalid password". It's frustrating when you want to get something done quickly or just use the iMac for a few minutes. I'm technically challenged, so if anyone can help I'd be grateful for step by step guides to fix this issue.
