ER706W and Alcatel IK41VE1 Something must be wrong with the ER706W Firmware
ER706W and Alcatel IK41VE1 Something must be wrong with the ER706W Firmware
Hi All !
I'm trying to use an Alcatel IKE41VE1 USB 4G Dongle as a Backup connection with the ER706W but it's rarely working.
First of all I have two other ER605 and the same dongle is working perfectly with those.
Problem #1:
ER706W is keep disconnecting as soon as it has got an IP address, see the log here.
It is doing it especially when Load Balancing is Enabled, simply just clicked in. And it starts dropping the USB connection if I'm going to the USB Modem Menu then I can see that it is getting disconnected like if I would physically disconnect and the identifying again gets connected for 2 seconds and again disconnected.
Problem #2:
If there is no Load Balancing Clicked in, then it is stays connected and not releasing the IP address and not getting disconnected.
But.
Despite that in Link Backup it's cleary stated that WAN2 is the Primary connection and USB is the Backup, the ER706W is still putting the USB Modem route to the first place.
WHY ???
While if Load Balancing Clicked in and there are some times when it stays connected for a while then the routing order is correct and WAN2 is in the first place and USB as Second, as soon as I unlick load balancing (but the link backup is configured), then it is starting to disconnect the USB and the routing order is changig to the incorrect order as shown on the picture above..
Again, on the ER605 the same dongle with the same SIM card in it is working fine, no Load Balancing clicked in on the ER605, and it stays connected and the routing order is correct, and also nicely doing the failover.
Devs, please check what's wrong with the ER706W Firmware as this is unusuable like this. (Unless I'm doing something wrong)
Tell me if you need any testing or more logs or more data. All the configs are default on the USB connection like MTU1480, all connection and authentication is on AUTO....etc

Hi @MonsterVic
Thanks for posting in our business forum.

Understand this, we may not have the same USB dongle like you have. We may not be able to get the same result as you do. The product was tested with the compatible USB modem before we released them and we have a list of compatible modems. If possible, we still recommend considering the compatible models we've tested. Or you gotta pick one by trial and error.
For other USB modem, they may work as long as their specs fit in the router but it does not mean we would guarantee you any of the modem would work perfectly. Based on the previous description, it seems to be a 4G provider issue.
Now with the new information provided, it looks like a software issue.
Second, AFAIK, there is no debug for the USB modem. But will check this with the team. Even if we are gonna do a debug, I will require a remote session and get you on the line with the dev to check that.
As you stated, it happened after 48 hours, not sure if there is a log in the device that can review what happened.
There is no similar feedback on the forum.
Can you confirm?
During the 48-hour test, there is no reboot to the system at all. Correct? Only the reboot happened after 48 hours where it appears to be completely disconnected.
USB WAN is on bridge mode or NAT mode?
Hey. Thank you for being helpful mate.
I chose the USB modem based on your compatibility list so it's an Alcatel IK41VE1.
And really if I plug i in into an ER605 it works flawless without any flapping any disconnecting, no problems at all, that said to me that it's not the USB modem which might have a problem.
Yes, there was no reboot within the 48 hours, and yes I have rebooted since the USB modem was reported completely disconnected, while it was connected, and the USB modem says identify successfully, and if I remove it physically then it stays the same, really it's kind of frozen when this is happening and reboot is solving only. It has happened now twice after about 48 hours. The last reboot was yesterday about 19 hours ago, so at the moment it is sometimes still getting and releasing DHCP (which is caused by disconnect connect on the USB modem menu) but after few tries it's ok, I just tested a simple ping to 8.8.8.8 over the USB modem and it's ok, replying.
I will wait now to have the hang up to happen again, will save the logs and let you know what happened.
USB WAN is on bridge mode or NAT mode? --> I don't see such option to setupWith the IP listed, I think it is NAT mode. Do you have access to the gateway? WAN IP and WAN gateway, use that gateway IP and access to the USB modem page?
That's not a function on the router but on the modem. It determines if it is a pure modem or an integrated modem router.
You mean when it shows up identified successfully but you cannot access the Internet. You cannot ping 8.8.8.8 while it is "frozen". Correct?
Ah okay, yes I can access to the modem page, but also there is no such option or info there, and yes it seems to be NAT not Bridge, it is simply using 192.168.1.0/24 as a range assigning an IP from this range to the ER706W and 192.168.1.1 is the Default GW which is the modem itself. Unfortunately I can't see any more network related details even on the modem page.
You mean when it shows up identified successfully but you cannot access the Internet. You cannot ping 8.8.8.8 while it is "frozen". Correct?
Oh yes I cannot ping, when this is happening then no IP address assigned to the ER706W from the USB modem, it's like the whole communication between the USB modem and the ER706W is frozen, it's not reacting to anything until you reboot, not even reacting to unplug re-plug it stays the same identify successfully even when it is physically removed.

Hi Clive !
We had 1 session last week Monday with the support team where they have setup a USB Debug logging to the /tmp dir. And we agreed to continue on last Wednesday to check the log which is only there temporarily and after any reboot it would be lost. But they didn't connect, then they said they will try to connect Last Thursday and Friday but they didn't connect, and now I have followed up 3 times with them what's next, how to move forward but they are not replying to me at all.
Any chance that you can help and reach out to them to kind of heads up that hey this guy is waiting for you for 10 days.

As we are having nation holidays this week, we are not able to connect the remote and check your settings as we have left offices. I am currently replying to this from my home.
Before the holiday starts, as I know, dev's was kinda busy. I arranged your case to the dev but the person who's in charge of the case did not get through by remote timely. We will come back and pick the case up as our holiday is over.

Just to update you on this one.
After couple of sessions where the devs tried some tricks, debug log, timeout increase....etc none worked, so I thought anyway I need two USB modems, let's buy the 2nd but a different one. So I purchased a ZTE MF79U and it's working nicely with the ER706W. Not a single disconnect for days. In the meantime I have truly tested the Alcatel in my ER605 and for a continuous 4 days testing it was working without any problem. So that's where I ended up to use the ZTE in the ER706W and the Alcatel in the ER605.
This has solved my problem, but the problem is there with the ER706W <--> Alcatel.
I wrote all this to the Support team as well, thanked for their efforts and suggested to close the ticket, and suggested to try get hold of an Alcatel and please test it out in the lab as it will much much effective for them as well to find the problem comparing to a remote session stuff.
Thanks for your help too, if you think this thread can be closed also since the problem is solved, even if it is solved on a different way than expected.

Noted. Will inform the dev regarding this and hope they can find out what is wrong and see if it could be optimized on the software level.
Thank you for your troubleshooting effort and time with us in this case. Appreciate it. Have a good one!
