R-200 Routers - Incorrect Default Configuration - IP - 192.169.11.1

Products Residential Wi-Fi

Hi 

I did discuss this with the team, however there is not such instance reported so far.

One surprising thing I notice is that an out of the box device should be having firmware version 4.3.1-R1 and not 4.3.2-R4. This is what we program at the time of shipment.

A question does factory resetting the unit restore the default LAN IP 192.168.11.1 ?

We upgrade the routers to the latest firmware.

Factory reseting the effected R-200 routers sends them back to the 192.169.11.1 default address.

For your viewing pleasure - attached are 4 ScreenPrints of one of the R-200 routers that had the default IP address programmed incorrectly into the router at the factory in China.

I did a factory default of this router at the bottom of the page on the R-200 Administration Tab in this router and made you these pictures, so that you can see the incorrect factory default IP address of 192.169.11.1

You will notice that this Router's MAC address ends in D6:A9.  We had another R-200 that we programmed yesterday that also had a default IP address of 192.169.11.1.  It's MAC address ended in D6:A1. 

In this particular batch of R-200 routers that we ordered and received, each router had the incorrect default IP address programmed in them. 

Using the two MAC addresses: you need to trace back to whomever programmed these routers and see how many other routers were sent to America in this batch. 

This uncalled for problem leaves a bad taste in our mouth.....

Hi Danny,

Is it possible to share with us few serialNo /MAC addresses for devices that have this issue.

We will try to find if a specific batch has some issue like this.

thanks

Yes I shall try to see if this MAC series has had some problem. 

thanks

I have given you two MAC addresses in the series. 

We have others which we had to put in service right after we got received them. 

It would take major digging to figure out where they are disployed and what their MAC address are.

Here is another R-200 router that was factory programmed with the incorrect default LAN IP address.

It also has 192.169.11.1 as the default LAN address.

Hi Danny,

thanks for sharing more info. I was able to get the manufacturing test results from the lot to which your previous MAC/unit belonged. There was no issue in the lot as a whole, however that particular unit was not part of the test sample.

Trying to root cause it further and will keep you posted.

thanks

Well, here we go again. 

Just change one word in the Subject Line above. 

Substitute R-190W for R200 and read the Subject Lline again. 

We recently received in our first batch of R190W routers.   The first two routers were OK.....  

Couldn't get into the third router with the correct dafault LAN IP address of 192.168.11.1.

As with the R-200 routers that we have previously reported, the third R-190W router out of the box has a default IP address of 192.169.11.1. 

Someone in authority at Cambium needs to go to China and find the software in the computer (or PLC) on the programming line that is stamping out the routers and loading the wrong default IP address in them.  

This is getting old!

Tomorrow, I will include two Screenprints of the "out of the box" R-190W router with the faulty default 192.169.11.1  IP address in it.

13

Attached are two Screenprints of the brand new R-190W Router with the incorrect default IP address of 192.169.11.1 right after it was taken out of the box and hooked up. 

Once again, someone in authority at Cambium needs to check the plant in China to find out which production line is flashing the new routers with incorrect firmware.

We have already had this problem with the R-200 routers and don't want this problem to continue further with the new R-190W routers.

14

Out of a carboard box of six R190W routers.... here is the second R190W out the box with the incorrect default LAN IP address.... 192.169.11.1

As with the others, this was before updating the firmware and programming.

15

Here is another R190W router with the incorrect default IP address of 192.169.11.1

Three out of the cardboard box of six. 

Again, the screenprints were taken before updating to the latest firmware and programming.of the router

See attached pictures........

For what it is worth, your formum software does not like pictures with .jpeg extensions.

Sending the pictures again of R-190W routers #2 and #3 with the incorrect factory default 192.169.11.1 IP addresses.

Hi Danny,

We have been trying to dig this, however we did not fins any problem in the factory. No other customer has reported this problem (this is something very basic to access the unit). 

Are you getting the units from a distributor? Can you check if there is any kind of config provisioning being performed

before it comes to you.

Can you upgrade one of the bad R190 unit to 4.3.3-R4 and then factory reset /reboot it. And then share the LAN page

screen shot.

thanks

The R200's came from one distributor, the R190W's came from another distributor.

No configurations are being done by either distributor before we receive them.  

When we get new routers, the first thing that we do is to unbox one at a time and plug them in to a stand alone computer.  After each router boots up up, it assigns the computer a temporary IP address, which should be something in the 192.168.11.xxx Class C octet.  

The next thung is we type in the default IP address (192.168.11.1) into a browser.  If we we can't get into router, we type in IP Config into a DOS prompt.  That is when we find that the router is serving IP Addresses in the 192.169.11.xxx range.  

Back to the browser.  Type in 192.169.11.1 and we can get into the incorrectly factory programmed routers.  Each bad router shows the 192.169.11.xxx on the main screens.

Next is to manually upgrade the router with the latest firmware.  After upgrade to 4.3.3-R4, the incorrect default IP address of 192.169.11 1 is still present.  

When I get back in town late this week, I will factory default one of the defective routers and upload another Screenprint.

As far as no other reports coming in, I would imagine that others are igoring this problem, just as we did fir several months befire reporting it.  After seeing the incorrect default IP address in 6 or 8 R200 routers, I finally reported it.  

Someone at the China factory needs to go and look at the factory loads in the devices that are being used to program the default configuration in the routers.

Hi Danny,

thanks for the detailed response.

in parallel we are also investigating to see where the problem is rooted. We are going to perform random checks

in the factory on the invetory to find out more.

For one the MAC addresses of faulty devices published we could see that it was successfully programmed in the warehouse. For that to succeed 192.168.11.1 has to work. We typically flash the new firmware, factory reset the boards and ship them. So theoretically we did not find anything going wrong there.

Is it possible for you to provide us remote access to one of the faulty units sometime using TeamViewer or something.

Hi,

Just wanted to check if by any chance  the WAN DHCP pool in your setup overlaps /includes 192.168.11.X range.

e.g. 

If WAN DHCP is  something like 192.168.X.Y/16 then the device has this logic to switch to 192.169.11.X/24  on the LAN side. (see attached screenshot from my device)

When testing the units are you even connecting the WAN port or not ?

21

I went back and tested one of the new R190W routers that was serving 192.169.11.xxx address on the LAN side.  

You are correct. 

If our WAN with DHCP is connected to the router before it boots up, it causes the router to change its default LAN address from 192.168.11.xxx/24 to 192.169.11.xxx/24 and serve address within that Class C Octet. 

We run a /16 subnet on our WAN.  We also run all of our routers in the NAT mode.

What is the rational that the firmware in the routers are programmed to change their defaut IP addresses from 192.168.11.1 to 192.169.11.1? 

I went back into the 4.3.3-R4 manual to see if I could find any reference telling us that the firmware is programmed to change the default LAN IP addresses, but didn't find any reference.   Might that undesired "feature" documented anywhere else?

Hi Danny,

Glad to hear that, that now we know what was causing trouble for you. 

This is a design requirement to switch the LAN side DHCP pool when the device detects a WAN network which overlaps with that on the LAN side. The software internally switches to the next available network pool. This is a must, otherwise we will end up in IP conflict conditions and system operations will be affected.

Since this does not explicitly involve users, it was omitted from the User Guide. However I think it is a good idea to include this information. I shall get the docs updated on the next available opportunity.

If this solves the problem you can mark the explanation/solution as accepted.

Thanks

Ha!

All routers do that - the WAN ip subnet can not be the same range as the LAN ip subnet. Most routers however wont automatically re-configure themselves so its quite nice that the router will still try and work if this is the case. 

Now I am going to throw a spanner in the works. 

We have had some issues with R190V routers issuing 192.168.11.50 as the gateway address and no web interface presents itself on either 192.168.11.50 or .11.1 - I had been ignoring it because it can still download its config from the cloud and works how we want it. 

I shall pay more attention next time i see this and try to document it like the OP of this thread.
