frustration

As if I don't have enough problems with computer hell at work... 

My Macbook at home has suddenly decided that it doesn't talk to the internet hub anymore... from reading around on the forums this seems to be a bit of a reoccurring issue which I can be fixed by separating the two frequencies that can be supplied by the hub and logging into only one... 

Mission accomplished... fingers crossed I can stay properly connected from now on...  Now back to my OU homework that was rudely interrupted yesterday ...
