Cisco 881W rebooting

Postby harddrive » Sun Jun 30, 2013 6:34 pm

On the 15th of Jun, I was testing webcasting using PVC and the Saturday night adult session of stake conference. We had 110 devices on the network at my stake center. About 7:30 p.m the picture and everything froze on us. The next thing that I heard was the 881W reboot. I was physically in the room when it happened.

The next day during the general session, one of my units had the 881w reboot on him twice. Both times were right in the middle of the general session of stake conference.

So I started to look at the uptime using Technology Manager ( and noticed an interesting situation.

I currently have six 881W routers in my stake. ONLY 1 has been up for more than a week the rest have been up under 3 days. I work with Cisco routers and I know that they are rock solid and they reboot for very specific reason.

1. there was an IOS upgrade
2. there is a malfunction piece of hardware
3 we found a bug.

So technology specialist that have access to TM, it would be neat to know how long your routers have been up, if you are using the 881w. Also have any of you experienced this issue and if so what has been done to solve it.

Ours have been up 2-4 days. I do not recall yet seeing one up for a week, but I haven't been watching.

We forced a reboot on one of ours 8 days ago, but that one has only been up since noon Friday (2 days), so it has rebooted again since.

Well, the 881Ws in our stake have also been up for only about 2 days. But that is unusual. I've seen times before when they've been up for several weeks, so it's not like they get restarted frequently. From the reports so far, I wonder if some sort of system-wide upgrade happened on Friday, which led to a large portion of the firewalls being restarted then.

I have 3 in the stake and are as follows:

1. 4 days, 16 hours - This would put the latest reset on the morning of Wed. June 26. This was not my doing.
2. 1 week, 6 hours - No surprise here. I remember resetting this one myself.
3. 9 weeks, 5 days - I believe this is right around the time we changed ISP's.

Each of our 881W's are on a UPS, so minor power dropouts shouldn't affect them.
So we can better help you, please edit your Profile to include your general location.

I have five units in the Stake I'm responsible for, here are the up times for each one at time of this post: -

1. 2 Day(s), 22 Hour(s), 20 Minute(s)
2. 14 Week(s), 2 Day(s), 13 Hour(s), 43 Minute(s)
3. 1 Year(s), 30 Week(s), 5 Day(s), 16 Hour(s), 41 Minute(s)
4. 1 Day(s), 15 Hour(s) - My unit installation
5. 23 Week(s), 2 Day(s), 59 Minute(s)

As can be seen by the figures, there doesn't seem to be any pattern to the resets other than that I know my own (4) unit, has probably reset at least 3 times in the last week!

1) 3 Days 22 Hrs 30 Min
2) 11 Hrs 20 Min
3) 8 Weeks 8 Hrs 56 Min
4) 5 Hrs 20 Min

Definitely weird.
