MBR1100 + 598U - lockups and restarts

stevemitchell · EVDO Newbie Joined: 09 Jun 2008 Posts: 9

Hi folks,
I bought an MBR1100 and 598U about 2 months ago for a remote location that has no other internet access. I have excellent 3G coverage at the location, and always get good download speeds.

My problem is that every week or so, the router "loses" the WAN interface and I have to reboot the router. This isn't so bad if I happen to be there, but I am not there that often, so once this happens, my connection is down. There is one server locally that must be able to reach the Internet to submit information out to a database.

I am running the newest MBR1100 firmware, have checked posts everywhere else, and have not found any issues that look similar. I'm using an external antenna to increase the signal, and the whole mess is hooked up to a UPS power supply with a generator. There have been no power outages or other issues.

I turned on syslog logging a while ago, and have the logs going off-site to a remote server. It shows nothing at the time of the failure. In retrospect, I should probably have the logs going to something directly connected (my server) locally so that when the WAN interface disappears, I can see what the log entry is.

Regardless, the other issue I see is that in the last 3 weeks, the router has reported the "WAN Interface is up" message, and that it's renegotiating the connection as if it restarted - 157 times!! I have not rebooted the router that often, and according to the logs, the router isn't rebooting, it's just bringing the WAN interface up again.

Is this normal? Do I have a defective router/card? What other diagnostic items can I perform to help troubleshoot this?

For now, I am working on a script that will reboot the router daily in case it "loses" the WAN interface again.

sounds like bad hardware or overheating, you would have to test the 598u seperately and a diff modem on the mbr

Who is the ISP on the 598u? Sprint? Verizon?

Hi,

I have an MBR1000 and U597 with Sprint, very good connection -72dB.

I have similar problems, the router disconnects and reconnects the modem every 2-3 hours whenever it is idle. And about once a week the router requires a hard reboot. It says there is no signal from the modem but as soon as I do a hard reboot, back to 100% signal. Warm reboot does not work. At one point I had to do the hard reboot daily, but I reflashed the firmware and it is less frequent now.

I was working with Victor at 3G support but he hasn't responded in weeks. He was supposed to contact CradlePoint last we emailed. I have only had the router several months and I got it at 3G. Maybe it is defective. The U597 works fine in my desktop without reboots.

Seems like our problems may be similar??

You guys may want to try adding a ping target in the router firmware. What this will do is keep the modem from going into a dormant state. Log in to the router and under Advanced and then under Failover/Load Balance there will be a blank for ping target with 0.0.0.0 in it. Replace it with a valid IP address such as 69.147.114.224 and that will cause the router to ping yahoo.com every 60 seconnds forcing the modem to "stay awake."

askat1988,

I received your e-mail this morning and responded to your direct e-mail address.

I am putting the ball in motion for a replacement router once I receive the pertinent information I requested of you via e-mail.

-Thanks for your Cooperation and following up with us.

My problem still hasn't been solved. I followed the advice here about adding an IP address to ping. My system still shows the connection stopping and starting now hundreds of times per day.

I've opened a ticket with 3gstore support, but at an average of a reply every 48 hours, I'm pretty displeased with the level of service. I bought from 3gstore because of their reputation, and a previous purchase. It's unfortunate that support isn't solving my issue, and taking so long to respond.

StevenMitchell,

3Gstore Support department has offered several solutions to the problem that you have been having. Unfortunately due to the constraints of where this product is placed, we are unable to do much troubleshooting. Having said that, we have recommended that you contact Sprint seeing that you are already past your 30 day trial with Sprint. From the looks of things, replacing the modem for a different model may be your only option at this time.

According to the long thread of email, after asking if there was anything else that we could do to help, the response was to go ahead and close the ticket.

Please let us know if there is anything at all that you feel 3Gstore support Department can do to assist you with your technical issues.

If you find that you are pressed for time, you may want to pick up the telephone, for calls have higher priority than e-mail at times.

Please forgive us for the response delays, Black Friday/Cyber Monday has been a very busy time for all of us. We wish to give everyone the same customer service and support that all 3Gstore customers have grown to love, however holidays and super sales like these can make for some very chaotic times.

Please contact us if you would like to continue your dialog with support, we would be most happy to help you!

-3G Support Dept.

Steve,

Just to let you know I was having many disconnects too. Victor got involved and Cradlepoint finally called. I decided to swap the router, but they did say that there may be interference between the router and the modem. That they had heard of this same problem before at least said I wasn't alone (something to note Victor). They suggested that adding an extension USB cable, thereby moving the modem away from the router, may clear things up.

If the new router does not solve my problem I will try the extension USB cable.
