Hi,
I have a Cisco 881 router wherein everytime a hotel is getting no internet connection, they will just restart the router and all came back to normal. ISP is not an issue here since we are getting connectiong everytime we restart. I tried issuing show interface commands and I cannot see errors on the interface. I suspect this issue is due to high load utilization of the router that requires restarting to return to normal. Please give me some ideas on this.

Hi
i have some idea
1.check for the negotiation of the isp mux to router need to be hardcoded to full duplex because interface resets have happened
2.enable logging server which can provide it is free , we can analze

hi guys,
just to update you on this. We ended up replacing the router since the customer had also upgraded their Internet speed to 100mbps. About 1-2 weeks already and we never faced any internet issue already.
many thanks for all your help.

Like I said, replace the router.
Thanks for the update.
