Thanks for your reply.
OK so airport express is a first gen with old software, in setup i chose 5gh only. Router is mounted in rack behind the receivers. Antennas are on the front of the rack.
If I check for networks on my phone I can find 2.4 but no 5gh and this router does not show up. If I check for networks on the macbook pro I can see all networks and their channels. So in the outdoor example there were no 2.4 routers, only a lot of phones.(they don't show up)
Antenna throughputs, = antenna v70 v75 v75 and then terminated. I don't know if this the correct way to do this..... could this be my problem?
And yes to the line of sight,RF2 on that gig.
I was running channels 1 2 and 3, found out tonight that if I use channels 1 3 and 5 it looks to work better. ( I've been playing) but there was no phones tonight , only 3 2.4 routers close by. RF1 tonight
If I use two channels side by side like (1&2) they seam to mess with each other. Does that sound right?
