Hi, we have a year or 2 old 2811 router as our uplink to the isp. Well 2 times in the past 2 months, this thing seems to fail. All of a sudden there's no traffic passing but it's powered and light up, one day was a heavy traffic day(the inauguration) and a week later it happened on a light traffic day. The first time we contacted our ISP and after about an hour we just rebooted the router and everything was fine. The second time, we tried to console in, and it wouldn't allow it, nothing came up, we disallow vty since its connected to the internet. We rebooted and its been fine since.
So, should I just replace the router? How can I check to see if errors are happening if we can't console in? Is there anything I can check at all?
Thanks in advance
