As the title says, I finally got an IOS image for my cisco 2621 router, the name of the file being c2600-i-mz.123.26.bin. Now, the problem is I am neither able to do tftp as I keep getting 'operation time out' error, nor xmodem as I get the 'no response from remote system' error. I have checked the ip address and subnet mask and gateway ip and they are all correct. I am pulling my hair!!!!
