Hi Brent,

the issue is likely how you have the SSID setup on the Archer A7.  Really only in a Mesh or Router-to-Range Extender enviorment would you be okay with the Same SSID on each AP.  When doing a host router and AP router with the same SSID you will see issues.  This is because you have two seperate APs broadcasting the same SSID and Password.  This means your client devices will not know exactly which one to connect to, so they will either not connet to either or constantly be jumping between the two.  It may even look like its connected but traffic won't pass.  

This is likely why wired devices work but wireless do not.  I would honestly recommend using one wireless or the other, unless the Archer A7 is far enough away.  If it is then just switch the Archer A7 to a different SSID.

Those likely worked like our SMB (Business class) APs.  Usually they are placed where there is minimal overlap so when clients are moving they are only in range of one AP, or they have a Mesh feature that make the system appear to be one network.  Mesh is more seamless but same principal.  Home networks tend to be a bit different because they are usually much more codensed in their coverage zone.  Too much overlap with seperate APs on the same SSID can cause confusion for clients as they won't know which device to connect to.  We will even see this sometimes on Router-to-Range Extender connections but not as frequently as to APs in one network enviroment.

If you are able to replace the Zyxel router and use the Archer A7 as primary you would potentially have access to the A7's OneMesh feature.  This would allow you to then use the A7 as the base unit and then connect Range Extenders from this list  you would be able to. You would create a newtwork similar to a whole home wifi system without the cost.  Using OneMesh you would be able to have a unified SSID and avoid all the mess with multiple APs.
