Please provide a screenshot of the menu you are on, so we can see what area you are talking about.  We also need to know the hardware and frimware version of your Archer A7

Sorry for the late reply.  If we aren't tagged we can sometime miss a customer's reply.  The page you are on is your network map.  That page will consistantly referesh. To make changes click on Advanced > Network > DHCP Server.  You can then make changes to device names here.

I looked into it further. Yes on the router the only place to change the names is in the address reservation section.  This is because the device name under auto DHCP is determined by the name of the device.  For instance if you rename an iPhone "My iPhone" then next time the dhcp renews the router will update the name to My iPhone.  

You can try one other option.  Use the Tether App.  in this app you can click on an idvidual client device and change its name by giving it a nickname, but this will only be for view in the tether app.  The router will still see the name it receives in the DHCP handshake.
