How can I get experience if no-one will give me a job

If I were to send my CV and covering letter in application for a job to any company or employment agency, for a specific network technician/ engineer post. They would see that I have spent several years honing my IT qualifications to the point that I have the CompTIA Network+ Certificate and am studying for the CCNA Certification. But lacking is the practical expoerience gained in actual employment, this is the down fall and reason I keep facing rejection after rejection.

So can any one give me advice on how to break into this prestigious profession given the lack of experience, but the quality of theoretical knowledge I have.
