HI - I am trying to add a 4G dongle to the back of my Archer V400 V3 and not getting anywhere with an old (3 year old) dongle I had previously acquired.

Does anyone know which make and model of dongle (chiavetta) I should purchase?

The modem is in tialy and my carrier is (would be if I get this to work!) TIM, I have all the connection details.

I found a lot of posts mentioning HUAWEI dongles but nothing conclusive. Does anyone have any real world experience on this or is it a case of trail and error?

Are tp-link ever going to publish a hardware compatibility list? IMHO flogging this model as a 3g/4g compatible w/out that list is checky to say the least...

thank you.
