Hi Neilpateluk,
It is hard to say, as I don't know anything about your netgear set up.
If you are talking about simple independent AP's than probably not, as none of them is likely to be a router.
If it is a mesh system, then typically one of the nodes is designated as a master node and usually has a router built-in (plus DHCP, port forwarding, and other features). If this is the case, you almost certainly should try modem mode.
A master node usually has, or can have, two Ethernet connections. One to go to the WAN (which you would connect to the Hub port 1) and the other to your LAN if you have one. The LAN connection would usually go to a Ethernet switch, which connects all other Ethernet devices in you LAN.
In modem mode, the Hub only supports one Ethernet connection, port 1. The other three ports can't be used.
Looking at it another way, I have:
Hub 3 -> Master mesh node -> Ethernet switch => secondary mesh nodes (and other Ethernet devices). "->" represents a single connection, "=>" represents many connections.
What worries me is that some device on your network is getting an already-in-use IP address and that's when things start to go wrong and stop working. For example, a device might work some of the time and then stop working for a while.
Of course, it could also be broken ports on your hub.
Good luck!
