In the last few weeks we have installed readynas for offsite backup and now every few days the router becomes so slow the internet becomes slow and when you eventually get into the router settings the cpu usage is 99%. To restore everything back to full speed have to restart the router. I am on the current .16 firmware it is frustrating that it is happening purchased a business class router but it is not working as designed.
In other posts users have posted that unticking Enable Policy Based Routing fixes it but no luck there other suggestions is to turn of wan traffic monitor but I have no such settings.
Since I don't have a service contract as it is just off the shelf router I am not able to post a bug to cisco.
Thanks
