I have one Aironet 1200 access point and I wanted to reset it password but unfortunately my IOS have found problem and it cannot work and I want to load the IOS again , according to the manual I did as follow but there is some problem would you please let me know what I should do in this case.
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 Jack Young. The likely culprit may be that you need to uncheck "hide extensions for known file types" on your TFTP server;
The problem could be that the Laptop (used for TFTP) Operating System is hiding the known file type. From Internet Explorer, go into Tools > Folder Options > View, scroll down until you find the parameter Hide extensions for known file types, and uncheck the box. This should eliminate the issue.
i cheched all the option are same as things that u mentioned and i as said before when i want to use the TAR command after a sce it gives me a timeout error again.what do u think in this case and i am sure my labtop and tftp are corect.
