Yes i know this, i tried to change its software but an error occured. I wrote these commands for a 5030dn v200r006 AP.
192.168.4.250 is the tftp server ip address of my pc.
ap-mode-switch prepare
ap-mode-switch check
ap-mode-switch tftp FatAP5X30XN_V200R006C10SPC100 .bin 192.168.4.250
error: it couldnt succeed due to faulty data link.
do you think why it was?
