I tried to upgrade the IOS of my router 2621. The image i istalled is c2600-i-mz.123-21b.bin. It is succefully installed but when i rebooted the Router it is not not detecting the WIC card at W0 and W1 slot. I have WIC1 ADSL card on these slots.
The imgae i was using before was 12.2.15-15T. I am having some problem with the ADSL line, the link was keep on flapping after a cable cut from the Telco. As solution i tried to upgrade the IOS and FW of the device for a try.
Can any one hlp me by suggesting an IOS for the router.
