I have 2 clients right next door to each other. Their signal is good, their CCQ will be good and the throughput will be good. I can do a receive speedtest and it looks good but as soon as I do a send speedtest to them their thoughput drops way down along with the CCQ. I have tried all different frequencies and it doesn't help. Right now I have them running on the one that works the best. My guess is some kind of interference in their area but I have tried all frequencies and it doesn't help. Does anybody here have any ideas?
