@francesc1 I have been using CPE710s for a few years but with shorter range and excellent connection. They also show full speed link. I used the speed test built into the CPEs and the most I could get was around 400Mbps at about 200 feet. Also set up at 600 feet in case distance was too short but performance dropped as distance increased, again with the units showing full speed link. So my conclusion on these units is they will not deliver to spec. I would expect half of what they claim at best.

I replaced them with Ubiquiti GigaBeam | airMAX AC 60. Cost is MUCH greater, but so is performance. They delivered to full spec and I get over 100MBs  down/ up at a little over 200 feet.
