ap3g2-k9w7-tar.153-3.jd.tar
Q: Can I use this file on an Aironet 1830 or 1540 series?
No. Those models use a different bootloader and require ap1g4 or ap1g5 images.
Q: What is the difference between ap3g2-k9w7-tar.153-3.jd.tar and ap3g2-k9w7-mx.153-3.jd.tar?
The “mx” variant includes Cisco Mobility Express (virtual controller) features. The standard “tar” version without “mx” is for traditional WLC deployments. Both are included in the same downloadable bundle.
Q: How big is the file?
Approximately 28–32 MB. The .tar expands to about 70 MB on the AP’s flash.
Q: Can I downgrade from 15.3(3)JD to an older version?
Yes, but you must use the recovery TFTP procedure. Simple web UI downgrades often fail due to partition size changes.
