Just had this issue with an 3650-48pd running 16.3.6. Replacing Cables didn't work so I tried a new stack module and that fixed it. Never checked to see if just re-seating the stack module would have done the same.
Might have fixed it! Clicking the TCP Adjust checkbox (Advanced tab on the AP) and setting the value to 1320 improved DL from 900Kbps to 55 Mbps. We think every packet was getting fragmented.[cid:image001.png@01D45CAF.78DAE2B0]
Experiencing the same issue with the OEAP600s and 1810s. 150Mbps down 10 up from the ISP, get 60 Mbps down and 10 up on VPN, and 3-6 Mbps tops on the OEAPs. Anyone else have issues the the 1810s??
