Firstly, don't worry about being out of work at 26. You're not going to retire for at least another 40+ years anyway, so there's loads of time to get a good career off the ground.
How are your overall IT skills? Are you a newcomer to the whole subject area, or are you already a self-taught hobbyist/enthusiast who has spent years learning about and tinkering with computers in your spare time? The good news is that capable IT people are in-demand, so even as a complete newcomer, it's a safe career choice. The only real difference is the time that it might take before you're able to seriously compete with Comp-sci graduates in interviews.
Without qualifications, your personal background will have a big influence on how soon you'll be able to find employment. IT is all about problem solving, so if you happen to be the kind of person who has been troubleshooting IT problems since you'd been old enough to reach the keyboard (figuratively speaking), then you might be in a better position than you realise - but you will still have a lot of tough interviews because you'll need to put forward a convincing case that you are a capable problem solver - which generally means persuading an interviewer that you are able to pick up any kind of technical, troubleshoot it, and then take the time to really understand all aspects of the problem in enough depth before attempting a solution - interviewers love to ask questions along the lines of "can you explain a problem you had and how you solved it".
Certificates like CCNA will always help because they are excellent for learning a set of really useful and important skills. Cisco keep their CCNA courses up-to-date; they are quite intense, so they also show that you have the ability to learn new things by yourself, and the bar is set fairly high, which means quite a lot of work is needed to understand the material well enough to achieve a pass. (As the other answer mentioned, the certificates expire after 3 years. This isn't a problem - if you have a relevant job where you're working with networks every day for 3 years, then your experience will count for more than any qualification)
If you happen to be a newcomer to the subject, then remember that a certificate like this is only a starting point - even with a CCNA, there's plenty more to learn about IT than anybody might expect you to have picked up in a single course (for example, how to write powershell scripts/SQL/RegEx, how to install/configure/administer a Windows domain, etc.). Without having those other general IT skills to backup the CCNA you may still find the competition is fierce against degree graduates who have been studying for 3+ years.
So, the Cisco certification is a great idea. The Microsoft certificates are also good. Make sure you've got a broader outlook than just a single topic. With the spare time you've got at the moment, it should be possible to pick up a range of skills. The biggest problem with those worthwhile certificates is the money you'll spend on the exams. You don't necessarily need a certificate for everything though - you can pick up many things from online tutorials. Furthermore, these things will be easier to learn in your own time than when you finally enter the world of work and you're trying to learn a brand new tool or scripting language on your own with a deadline in front of you and a problem that your future boss has asked you to fix.
Good luck!
