I have tried a plethora of graduate roles within a variety of industries, I just can't catch a break.
I've also noticed my local college does a 15 week course in CCNA, says after successful completion of the 4 modules I can go to a test centre for Cisco Accredited Qualification, is that worth considering? £15 registration fee, hah.
Networking is a business in itself really if you like it. A CCNA is a good place to start if you enjoy this type of thing but I'd suggest you teach yourself a good understanding on bin/oct calculation if you have the time first. Knowing the OSI stack well before you go in there would be great too.
The test fee might be worth checking out first though, it can be quite a bit.
