rb230 whit a 3g modem

RouterOS General
1

Hi all,

I have a very serious problem with installing a 3g modem huawei 660A pcmcia on a rb230.-
When I plug modem in a pcmcia slot I’m having random reboot before modem connect.
When I plug modem in a pci-pcmcia adapter slot the system hangs.

After probing with several linux kernels versions nothing changed, same behavior.

E660A needs 3,3v with 750mA. Maybe the problem?

Regards.

I worked out the first problem by uprading bios version: 1.3.7 to 1.3.8 and it worket by 2 hours. Now I have another very hard porblem:

I was connected to the modem for a 2 hours and then I rebooted system to test it. But after a minutes system hangs and all leds is blinking.
I rebooted and I get:

RouterBIOS-200 v1.3.8 MikroTik ™ 2003-2005

RouterBIOS-200 v1.3.8 MikroTik ™ 2003-2005

RouterBIOS-200 v1.3.8 MikroTik ™ 2003-2005

RouterBIOS-200 v1.3.8 MikroTik ™ 2003-2005

RouterBIOS-200 v1.3.8 MikroTik ™ 2003-2005

RouterBIOS-200 v1.3.8 MikroTik ™ 2003-2005

and so on.

And I can`t make downgrade bios.

What can I do now??

regards

This is a power supply problem. I have again original problem.

can anybody suggest something about rb230 random reboot with a 3g modem pcmcia?

What are you using to supply power to the RB230?

I have been tried with:

48 VCC Output 0.5 A
24 VCC Output 1.2 A
20 VCC Output 3.4 A
24 VCC Output 6 A

and nothing changed.

now I suspect that it’s a signal problem.
because I moved to another location with best performance signal strenght and random reboot disapeared (after ugrade bios).
The situation is: modem 3g installed on a rb230 sometimes reboot with poor signal strenght.
Next step maybe I would get a aditional external antenna.
