Hi,

My CISCO 1841 router stop working after every 4 to 5 days and all internet application stop working and after reboot it start working normally. what could be reason?

here are interface statics

How do you conclude that the router stops working after 4-5 days. Did you trying shut/unshut for the LAn and WAN interfaces?

[shymin23]

The LAn interface shows input and CRC errors. Clear counter for the LAN interface and observe whether the errors are incrementing. If they are then it could be to do with a faulty port or cable.
