I facing problem after upgrade to 50mbps by using WIFI.Their router wifi become bottleneck ,max out transfer speed at no more than 40mbps.WIFI signal strength is good , -28dBm to -33dBm ,fixed to N WIFI , change channel to avoid interference (only 3 access point detected which from my neighbours ) but still getting below 40mbps.Hardly can get above 30mbps just for wifi transfer rate, even though transfer from wired to wireless with below -35dBm. Contact their CS , just know keep on reset my port although I already informed bottleneck at their router WIFI.
