Huawei B310 is available in India through only Airtel carrier, which comes locked to Airtel network. Huawei B310s-927 can be unlocked by soldering the cable. It is also possible to change the firmware and WebUI. You can also purchase unlocked B310 from our online store. It comes with an internal antenna, which is enough to catch the signal. But what you will do, if in your area signal strength is weak and you want to connect an external antenna.

How to Put External Antenna in Huawei B310 Router?

1. Unscrew the device.

2. You can see a wire is attached (we have market ends with 3 and 4 no.s). This is the internal antenna.

  1. Hi Kamlesh,
    Glad to hear from you.
    I think it is blocked. I tried putting external antenna on unlocked Airtel E5573s-606 MiFi router.
    This is the antenna I used.

    I could hardly get any gain. So, like you said it is probably blocked.
    Do you think I should follow this same process for connecting external antenna for Airtel E5573 also ?
    Also I want to buy Unlocked Huawei E3372H (Idea Logo) ? I sent you an email about that.
    Please reply to that email also.

  2. Hi kamlesh . Why do we need to cut the wires and join to other (as mentioned by you) when the option of adding external antenna is there on the back(sma ports) with setting on router page.

  3. Hi,
    I have a problem, I got the B310, in the information tab I got: B310s-22 firmware version 21.313.06.03.58.
    I bought two antennas from Ebay:
    http://www.ebay.co.uk/itm/272477927903
    and
    http://www.ebay.co.uk/itm/152350207228
    The router configuration page under the antenna tab got the option of:
    Internal
    Automatic
    External

    If I connected any of the external antenna, and set to automatic it reverts to internal, and if I set to External the router accepts, but I get exactly the same signal.
    So I am assuming the antennas are never in use.

    I did not open the router to avoid losing the warranty, and according to

    It depends upon the firmware, if firmware supports external antenna then it is not required.

    My firmware was supposed to accept the antenna right?
    Do you guys think I should try the soldering any way?

    Thanks,

  4. I am in Siem reap Cambodia and I am “testing”. a free trial the B310. Do you know if the external antennas are disconnected in the same way as the ‘Airtel’ Carrier one. My carrier is Kingtel and they are upstart company. I get only one bar inside, but if I get the right spot outside, I get two of the possible three with steady and fast signal from both conditions. When I connected a T-Link antenna, it shoved no gain. If I open the box, I will own it. So any help or suggestions would be grateful. Maybe two antennas are wanted and needed if they are connected. Thanks to all.
