Hello, I don't have any knowledge of my D-link 2750U, got it on the recommendations of a friend. Had it for 3 yrs. & never had & issue. Connected to my desk top, laptop, Uebo media player, even my wife's tablet, no problems.
My laptop is about to die for the third time, & old HP 2007 I had reworked. So I got an Acer which won't connect, in fact when I try message says "Windows cannot connect with my network" doesn't even allow me to enter the security passkey. Have tried everything I can find with the exceptions of messing with the router settings.
I don't want to knock myself off line by changing something not knowing what I doing. So in closing I now have four devices working on my network, & a brand new laptop which I can't connect to the internet wirelessly.
Tried connecting Ethernet directly, no issues.
DP.
