Looking to change Cisco AIR-AP1242AG-A-K9 from mode reset lightweight to autonomous. Downloaded the Cisco file "1240-k9w7-tar.123-8.JEA3" & unzipped it to "c1240-k9w7-mx.123-8.JEA3". Finally renaming it to "c1240-k9w7-tar.default" & following the PuTTY / Tftpd64 procedure to upload image in order to change to autonomous. Have doe this several times with the same error noted below "Tar checksum error in tftp://255.255.255.255/c1240-k9w7-tar.default". Any help would be much appreciated.
