I am pursuing my training for CCNA and I bought an 2811 Cisco Router but the flash card is completely empty and contains no iOS. I scoured the internet to download an iOS so i can use a card reader and install it on there but I can't find anything. Is anyone out there that has an iOS compatible with 2811 and can send me the file? I know the 15.1.4M12 version works but i'll take anything really.
