The mode receiving should be on Client mode, not AP mode
701 its not the device for this
Buy 2-Pharos 510, if the 5Ghz band is allowed in your country
2.4Ghz is a crowded band, you might have issues in future
The one on the internet side set on AP mode the one receiving in Client mode
And don't know why you want to place a pair of AV-500 between the link
Neither of those 2 antennas where designed for the 701, it does not have the power to handle their dBi, those antennas where designed to pair with CPEs
