Issue Converting LWAP to IOS

[sabrautigam]

Good day all, this is my first experience converting LWAP to IOS so please bear with me. I have followed all the major steps such as changing the TFTP server's IP within the range 10.0.0.2 and 10.0.0.30 with subnet 255.255.255.224 as well as changing the desired image name to c1200-k9w7-tar.default. After holding the mode button down till it turns red and releasing it goes into image recovery mode than examines the image, it than gives me the error "Failed to open archive file tftp://255.255.255.255/c1200-k9w7-tar.default" and than resumes with loading its original image. I do see the attempt hit my tftp server (solar winds) but says "error 10.0.0.1 requesting c1200-k9w7-tar.default: file does not exist". I am a bit confused because when initially trying to recover the image the 255.255.255.255 tftp location does not seem right yet it still shows up in the TFTP server log. Any help or insigt is greatly appreciated. Many thanks,

SB

Hi Steven,

This sure sounds like a TFTP problem. Have a look at the details in the following threads that all have to do with TFTP. There are some great hints for troubleshooting TFTP problems from some of my favourite NetPros like ScottMac,Stephen from Cisco and JackYoung. The likely culprit may be that you need to uncheck "hide extensions for known file types" on your TFTP server;

The issue has been revolved thanks to both of the comments provided. It was indeed the extension that was causing the problem. Thanks again guys, someday I will be the wireless jedi that I aspire to be :)

Focus on your tftp server. Solar Winds tftp server is ok that is what I use. Check:

1. If the image file is in the correct folder

2. If the image file is correct (check in the DOS mode). If you changed the file name in windows, that ends up with xxxx.tar.default.tar.
