No client can connect to our new Metal 2SHPn because the RX strength that the 2SHPn "sees" is very poor (the clients are laptops 100 metres around) and we are using the included 6dbi omni antenna.
The clients can see the 2SHPn Access Point full of strength, but they cannot get a DHCP IP address because they are inmediately disconcected (extensive data loss).
We have tested with different frequencies (but there is no other WiFi activity near), but nothing changes.

Any advice?
Kind regards from Madrid
