I'm not aware of anyone that offer a CCNA Wireless lab rental.
Take a look at the Cisco Learning Store for the WIFUND course. Not sure if the labs that are provided are good, but you can apply for a trial version and verify.
Welcome to the Cisco Learning Network!
I am not aware of any Official CCNA Wireless rental.
But, I would recommend that you check the Official CCNA Wireless study resources available at Cisco Press.
You can check the current study materials available for the CCNA Wireless certification at the following link:
Furthermore you can find the Exam Topics at the following link: WIFUND Exam Topics
You can find additional FREE Study Material and Practice at the following links:
Also check out the Cisco Learning Network FREE CCNA Wireless training videos available at the following link:
Furthermore you can check the E-learning option available at the Cisco Store. This Cisco self-paced course is designed to be as effective as classroom training. Course content is presented in easily-consumable segments via both Instructor Video and text. Interactive activities are available through Discovery labs, content review questions, and challenge questions. This makes the learning experience hands-on, increasing course effectiveness, and provides students direct feedback on how well they have mastered the material. Gamification features are built in, including earning badges and a leaderboard, to encourage better performance. It also includes a FREE trial version. You can review it at the following link:
Finally, I wish you all the best in your CCNA Wireless studies.
You can try a virtual WLC.
It will get you close to the real thing but not fully but I think it's close enough for the exam.
This still leaves the APs themselves though.
If you are close, I can lend you my WLC and APs (3 light weight and one autonomous)
Also have a spare POE switch (3750) that I am not using for my IINS studies now.
