I have an RB2011UAS on ver6.17 set as an AP. The channel being used, 2417 is clear and the country domain for power is set at US. When the band is set at B/G/N and when testing with Speedtest.net, the connection will drop most every time during the upload test. When I change the band to B/G only, the test works fine. I have tried this test with two different laptops and WIFI chip sets. When working with B/G, the upload speed is reported at 5Mbs.

Anyone have ideas on what is going on or what else I can check?

Cheers!

Probably too much tx power, it blind your devices.
