How did you reduce power?

/interface w60g set 0 tx-power=[1..15] or default.

In my case set 0 tx-power=10 works great, it links fine with 5 as well.

However, be careful with this setting when updating firmware. If they make changes to the antenna patterns you may need to change/remove it.

For a reflector to work properly you really need to "flood" it with radiation.

If the antenna main lobe is more like a sharp pencil the reflector won't be so effective.
