Any ide why my P2P signals went from 45/50 to 62/92?

Which device?
What circumstances?
What kind of client?
What config ?

911G-5HPacD - Jirous dishes - 12 Km , 802.11, literally nothing was changed just did upgrade from 6.43.14 to latest OS and this happened , wanted to downgrade but cant even log into the far link, it is P2P link , same if i change for NV2

I recommend to try with the latest versions of ROS and keep the last version that works good for you. If you can't login on remote device, you need to downgrade it physically.

Regards.

It's possible that the antenna gain has changed on the radio to contry regulations reducing the power causing the signal to change. Did you upgrade both radios or just one?

Choose superchannel and no country for maximum power.
