I replaced my Archer 1750 which I think was a V5 with this newer model because I was having inconsistent connection problems, it was difficult to upgrade (which I didn't try) and thought a newer model would be better. Testing with Speectest.net, I regularly got close to the 20 mbs promised by my DSL ISP. Now, however, all my computers regiater closer to 10. We have several computers all over the house all of which were getting near 20 now getting near 10, on both 2.4G  and 5G. Im wondering if there is a stting I got wrong, such as the one to prioritize one computer over the other (which setting I have turned off). There have been no changes in the computers' equipment or locations. Any thoughts? (The connection problems with the old router don't seem at all similar to what I have now, and were more like some times there was a delay or waiting period and switching from 2.4 to 5 or back would solve them)
