The satellite internet service for the folks at the AABC center has been poor recently, and the drop in service seemed to be coincident with the start of our operations. At Paul Johnson's PC, DNS was not working, and I couldn't ping their DNS servers, or the google DNS servers: 8.8.8.8
I tried turning off the etherant wifi at the Lidar, since that was closest to their satellite dish. They rebooted their satellite modem, but there was no improvement.
They then had an ISP tech come out to check their dish alignment, and replace some components. That improved things but it still appeared to be worse than before SOAS.
So we tried adjusting the TX power on the AP24 at the base trailer. It is pointing basically straight at the AABC buildings.
The previous setting was
interface wireless print 0 ... frequency-mode=manual-txpower antenna-gain=0 tx-power=15 tx-power-mode=card-rates
- frequency-mode
- manual-txpower: transmit power is taken from tx-power setting
- tx-power-mode: Choose the transmit power mode for the card.
- card-rates: use card defaults rates
- tx-power: -30..30, default 17. manually set the transmit power of the card in dBm, if tx-power-mode is set to manual or all-rates-fixed.
From the above settings I don't know what transmit power would be used, 15 dBm, or the default for the card.
Anyway, on Jun 11 I changed the tx-power to 13 and Paul saw an improvement.
Later I changed it to:
frequency-mode=regulatory-domain tx-power-mode=default
According to Scarlet on the AABC office things are working fine. We'll leave it at that until we hear otherwise.
