I have the next situation, 9 LAPs 1142N, i wish to convert them to autonomous, it seems that there is a 2 ways, with a simple copy tftp flash: commands and force them to charge the IOS.default image(holding the mode button), what is the correct way??
I used the first one (copy tftp flash and etc commands) decompressing the winrar file downloaded (c1140-k9w7-tar.124-25d.JA1) and just selecting the .JA file inside, then using the boot system command, but when a try to use the browser appears with out menus! buttons and etc options!, I supose that I need to charge ALL winrar file, but how? some suggestion??
Sorry 4 my English hehehe...
OK, it looks like you are trying a couple of things simultaneously. You have renamed the image to .default (c1140-k9w7-tar.default) in one instance (to use the mode button). In another, you have extracted the archive before loading. The AP trys to extract the file, therefore when it opens the file ending in .JA1 is is confused-- thus the message %Error opening file...
Lets do this, because it seems clear your TFTP is working.
1. Have the following file in the root directory of your TFTP server: c1140-k9w7-tar.124-25d.JA1.tar ** do not extract this file **
From the AP, it seems you are already addressed and have forced AP to not reload so lets issue the following command...
2. #archive download-sw /f /o tftp:///c1140-k9w7-tar.124-25d.JA1.tar
AP should then be able to "open" the file and with the archive command given above the AP will have extracted the image and overwritten as the boot image and then reload your AP.
Give that a shot and tell us what you find
