Cant access R201 router.

I have been able to to a reboot via cnMaestro.  Then I can get into it from the LAN  or the WAN side. If it is a router that I am on site with I reboot it with a power cycle and then I can gain access.

Yes, I reboot them from cnMaestro as well when they stop responding. Definitely something amiss. I had opened a ticket about this a while back, and the solution offered was to make sure the routers didn't have public IPs. That's not exactly an option for us, so we're stuck rebooting from Maestro when we need access until we can generate enough buzz to get it fixed.

20% of my online routers I can't access the web interface currently. Of those, 75% are on the newest fw release.

Hi,

We have been trying to reproduce this situtation in our lab ever since Steve reported it. However we are not seeing the issue. Is it possible for you to get us a tech-dump from cnMaestro once the device is in this state ? This will help us to determine if there is a problem in the web server process.

It would also help if you can provide any details to help reproduce this issue. Please drop me an email ashutosh.datta@cambiumnetworks.com and I shall send you a config file that will help us drop into shell once the device GUI becomes inaccessible.

thanks

Hi

We are able to reproduce this , will root cause it and send you update.

thanks

Good. 

We have been accessing several remote R-200 routers trying to find another one that we cannot get into. 

So far, all have been accessable.  

Have not seen a particular reason for the cause of not being able to access (ie: firmware updates).  In our case, they just seem to randomly be unable to be accessed via the GUI.

We just got our first batch of R-190W routers.  Starting to program them and put them out in the field.  Will advise if we see the same problem with them.

We thank Cambium for coming out with the R-190W routers which are "Plain Jane". We have no need for SIP and don't want to get in the SIP VOIP business, because of the FCC regulations of reporting several times each year and paying fees to the FCC's ULS Fund.  Buying routers with SIP in them is a waste of money in our (and many others) case. 

Since I have never seen it brought up on any of the Cambium forums......

For those in the U.S., if you are not familiar with the above and are providing SIP VOIP to the public - I would suggest that you do some research on the FCC Web Site. 

While I am at it, for those in the U.S., if you are offering Internet service to the public, you are required to report a bunch of information to the "Frendly Compensation Company" twice a year on FCC Form 477.  Pain in the xxx. 

I would wager that many on this forum are not aware of the above requirements. 

Welcome to the world of more taxes and government control. 

I have a router in the can't access state right now but as luck would have it cnMaestro seems to be down so I can't get a tech support dump.  When cnMaestro comes back online I will send the download.

Steve

It seems they have already replicated this in their lab. Cambium, do you still need tech support files?

No, tech support files are no longer needed. We saw the issue on one of our device and we were able to gather the required data. The engineers are trying to investigate on this.

Hello:

I realize this thread is a few months old, but I'm curious if the solution was ever identified? My ISP uses the cnPilot-R201P and I'm having the same trouble. 

Thanks,

Rachel

Hi Rachel,

can you explain the issue you are seeing.

What version of software are you running ?

Are you able to access the device via LAN port ?

Have you tried accessing as https://<ip-address>

Since my original report to the forum on this problem on 10-17-2017, we have seen this problem several other times on multiple R200 routers. 

Can't access the routers via http or https, until you power cycle and the router reboots.

Still no fix for this? I'm running 4.3.4-R8 and after some unknown period of time the router will not bring up the GUI.  I can ping it but it will not serve out it's log in page.  Both http and https.  This was reported over a year ago.  I reboot the router and then it shows up. This is happening on several of these routers that I maintain.

Steve

The problem: when the router is initially powered on, I can access the administrative interface through the WAN IP (from an outside network). After a certain amount of time, and I haven't yet figured out what that is, the admin interface stops responding and I have to reboot the router if I want to make a configuration change.

-i cannot access the admin interface from the wireless LAN;

- I believe I can access through a LAN port, but I'm usually wireless so it's just as easy to port forward through an SSH tunnel and come through the WAN than it is to go use one of the hardlined computers.

Software is 4.3r9.

I get an invalid certificate authority alert if I use https instead of http.

Rachel

Hi Rachel,

In current 4.4-R6 Release,  we have added fix for this behavior, Please update the image of your device to 4.4R6 and provide your observation.

What is the status of the correction of this problem of not being able to remotely access the R200 routers? 

We continue to have the problem of periodically not being able to remotely access them?

These routers are anywhere from 30 to 250 miles away.  When we are unable to remotely access a router, we have to drive to the affected location, unplug the AC power and reboot the router. After the reboot is done, we are then able to remotely access the affected router - for some period of time, until the problem re-occurs! 

We must have 100% access into each router all the time, to add LAN Devices and Port Forwarding numbers into each router, which we do on a weekly basis.

We had two more R200's with the same "no-access" problem today!  Not good.....

If it is of any help, each of the R200 routers have continuous data flowing inbound (Wan to Lan) in the area of 500 KB.  

This problem is getting OLD and is making it impossible to us to continue to deploy the R200 routers. 

Do the R-190W have the same "no access" problem? 

Again, when are we going to be able to see the fix for this problem?

I upgraded to firmware 4.4R6 and it seems to be fixed so far.

Steve

I would love to try version 4.4R6, but it has been removed from the download site - due to problems.

Hi Danny,

Please provide your e-mail id to send the  4.4 test image to check this issue(My Email Id:niraj.mahapatra@cambiumnetworks.com).

I am having the same issue I am currently running 4.4.2-r2.  I can access some of the devices, but not all.  I can ping, I have tried IE, Edge, Chrome none of them will connect to 192.168.11.1 or https://192.168.11.1.  Any suggestions?  

Same issue R201

(00:04:56:xx:xx:xx)

Out of the box first time 192.168.11.1 worked fine. Could access the web ui.

Half an hour later cant access the webui.

Can ping 192.168.11.1. I even get IP address and internet through LAN ports.

Can SSH in to it and log in. (can't find any usefull commands for SSH)

Tried to factory reset several times. Power on and off. Nothing helped.

Also tried to claim device on cnmaestro but the device is not responding.

So unless there is  a way to uprade the firmware through SSH  and fix this, I have to RMA the device.
