+2. Turn off led indicators.
+3. Turn off power saving.
+4. Turn off band steering on 2.4 GHz and 5 GHz.
+5. Set the 5GHz channel to fixed 100 (see: <https://en.wikipedia.org/wiki/List_of_WLAN_channels>) if it is not interfering with a neighbor's WiFI. Note: 100 is a good choice because it has fewer devices on it and it has enough space for a continuous 80MHz resp. 160 MHz channel width. European weather radars are on channels 120 - 130 <https://www.shmu.sk/sk/?page=2037>.
+6. Band width 160 or 80 (prefer 160 if the signal is strong enough).
