Archer D7 bandwidth issue
I have a 20 megabit profile and my ISP says my home is reached by 12/13 megabit as shown in the image below taken from the modem Status menu:
The issue comes when I do a speed test (via ethernet, no load on the line) and it comes out that the effective speed I get is 7 megabit.
Is there any setup I could trick or maybe a suggestion on what should I check?
PS. Don't know why it can't let me select Archer D7 as model
