LG 27" 5K Ultra Fine LED Monitor Black

Does it come in the original box?

Probably brown or white box.

this product is fixed wifi router problem?

I’m sorry, I don’t understand the question.

Is this going to be shipped via Amazon? With FedEx, UPS or USPS?

This is shipping directly from the vendor. Most likely FedEx.

I believe the questions is about the earlier 5k panels having problems when wi-fi router is nearby. Later versions of monitor were fixed, and I imagine OP is asking if these are the new updated one, older fixed ones, or possibly older non-fixed ones.

Can you confirm? THANK YOU!

Ah, thank you. Unfortunately, this item is no longer for sale.
