Very unstable 3G Internet (via Novatel MIFI 5510L)

Hello, I have one problem: I have a very unstable 3G internet for 1 month. Modem Novatel MIFI 5510L. It was flashed 2 months ago (in the service). Here is the problem: my speed is 20-30 kilobytes per second, catches 40%, 5 minutes was the Internet and all. And I reboot it. What to do?

Answer

Hello. Do you have a modem without an antenna, or do you have an external antenna installed? Is it far away from the tower? Is the problem only in low internet speed, or in constant connection failures?

The reasons can be very many. I will list the main ones, maybe you will find something useful.

I had a similar problem. Modem all the time went into X1 mode. After that, the speed drops and connection drops. I took him to the firmware. You write that you also flashed. Maybe they did something wrong. Bring it back again.
The problem is with the operator. Something with the base station. Call the operator’s support. Let them handle it. They can see all the information on your connection. Speed, drops, etc.
Hardware failure in your modem.
40% isn’t the worst signal strength, but it’s not great. I have 60%. Try to adjust your modem (antenna) for better reception with AxesstelPst EvDO BSNL 1.67 program.

But I think the problem is in the modem firmware and in this “X1” mode. The service center should definitely solve the problem. Or let them give you a new modem and Novatel MIFI 5510L for checking. Not only that their speed is already bad, but also such tricks with the equipment. I’m sick of it.

It turns out that you can change the mode of operation yourself (disable x1), through the same program AxesstelPst EvDO 1.67. There are instructions on the Internet. Here is one of them: http://netobzor.org/forum/index.php?topic=562.0 The first method is recommended.
