MR5100 no signal without external antennas

MR5100 SKU MR5100-1TLAUS Only works on the external antennas. If it is disconnected from the external antenna, it does not work and a message appears mobile broadband is disconnected. It was working before and there were no problems, but after connecting and disconnecting the external antenna, this problem occurred. I have updated to the latest firmware to check if that problem will be fixed after the update, but the same problem still exists. image_67173889.JPGimage_6483441.JPGI have attached the images of the antennas. Can someone help me to fix the issue? Thank you

Looks like the external antenna connectors are broken. Without the external antenna, the internal antenna will not have the proper contact if that is the case.

Thanks

Try a simple factory reset?

As you told me the issue is with the external antenna ports, I replaced both TS9 connectors, but nothing has been changed. Router still works only if an external antenna installed. I guess this may be a software issue. Can someone help me fix this please?

Re: MR5100 no signal without external antennas

internal antenna is not soldered but a flexible contacts, it might be caused by the contacts are loose and that is lead to no internal antenna connected. It is not suggested to open the device by yourself but request for RMA.
