Hello

I recently buy TP-LINK Archer T4UH, because I have one notebook that not supports wifi 5 GHz, i a Lenovo G475 (a Little old) but with this device must see it, but I don't see in fact I see the wifi 5g of a neighbor. Strange isn't ?

Algo I plug the device in another notebook more new (Lenovo y700) without the device I see the 2 wifi, 2.4 and 5 GHz. But from tplink only see wifi 2.4

I don't understand what happens?

Can someone help me please.

Thanks
