Thanks, we are still having the problem with verizon USB760…our Sprint U300 is much more stable…

We are still working on the problem. Please keep forum posted as we will also.

videoicu,

You are NATting the ppp connection to Verizon, right?

videoicu,

One thing I noticed after hours of working on this is my NAT rule was not showing packets increasing. It was always 0 (zero).

So, I deleted the NAT rule and recreated an exact same rule and the numbers started increasing and the connection is now working.

With the old rule in place you can CLEARLY see that the NAT rule was not working and that RFC1918 addresses were going to Verizon’s network. When they see a bunch of these they kill the PPP connection. With the NAT working this does not occur.

I don’t know how I got this rule in this weird state but it’s very replicable at this point. I have an old config that I can boot to and see the situation occur with torch. I delete the rule, recreate the rule and NAT begins to work.

This has got to be some type of MIOS bug.

Yes definitely NATing…can not bridge with the PPP usb.

I will check my settings and get back to you with them so we can compare.

What I did was delete the rule and recreate it. I also selected the output interface to be the PPP interface. So it only NATs when the interface is active. It’s been working very well this week.

So are you saying that the USB760 works properly now? If I use it with the latest 5.0 version, I shouldn’t have any problems now, correct?

Thank you.

Hello everyone!
We also tried to setup Verizon Wireless USB 760 with ROS 6.10 but at the moment without success.

waiting for packets...

Our settings are:

Data Channel: 0
Info Channel: 0

Phone: #777
APN: empty
User: empty
Password: empty

We also tried different channels, usernames and passwords, modem init, dial commands.

Modem work fine via Broadband2Go software.
In Verizon Access Manager I can’t see the modem to change WWAN settings.

Thank you!
