OTG Micro-B plug and Standard A receptacle for USB modem

角色

如果你的USB Modem能在MikroTik的OS认可，那么你可以通过OTG Micro-B plug to Standard-A receptacle，再加上适当配置，那么你的USB 3G在routerboadrd就可以上网。



然后插上我的modem在RB2011UAS-2HnD-IN，只能做到

1. [admin@MikroTik] /system resource usb> print
   
2. # DEVICE VENDOR                   NAME                  SPEED

4. 1 1:6    HUAWEI Technology        HUAWEI Mobile         480 Mbps

Huawei E1550 modem on MikroTik RouterBoard

I know whether the problem came from the Modem that I used or I did not know how to make it work.

回復 6# Qnewbie

Did you insert any SiM card into the USB modem? What kind of modem that you used?

角色

Were you able to connect the Internet via the modem?

角色

My E1550 modem is also able to give the same results as Qnewbie did

现在modem可以用console连上internet，但是在其他etherX不能上网。

Now I am able to use the 3G modem to connect internet and write this message. The most important issue to add a router from the 3G modem to the current network by

1. /ip firewall nat> add chain=srcnat action=masquerade to-address                                                                             es=0.0.0.0 out-interface=ppp-out1

After adding, I moved the above rules to a suitable line.

For completeness, I included all the rules in my RB for your interest as follows:

Thanks!

Now I am able to access the Internet via my Huawei E1550 3G modem which was a gift when I renewed the PCCW broadband contract.

角色

Thanks you for your advice.

By the way, what the lowest and best offer of the data plan in your area?

角色

The plan is very good and not expansive. How comes the mobile phone charge is so high?With the low price data plan, you could make and receive voip calls via the data plan, right?

角色

The major issue using data plan to make phone calls is the delay! However it will be much cheaper then ordinary mobile operators.

角色

When the same data card was moved to another 3G modem which is specifically used for China Union network, I was not able to access the broadband internet.
