We have four R350's connected to the same POE switch. Connecting directly to the switch we are seeing consistent speed tests of 150/40. Walking around connected to the Wi-Fi we are seeing 10/10 consistently. The only variation is that sometimes it might be 10/9 or 9/9. We have verified that there are no rate limits applied.
We just installed this 2 days ago and am hoping that there is something we are overlooking?
