Since changing to a PPPOE ISP yesterday, my MX105 seems to be throttling speeds and I have no idea why. I was with Virgin Media (VM) who use DHCP public IP addresses but my new ISP (BT) uses PPPOE. I should be getting 900Mbps down and 110 up but I’m only seeing 350 down and 0.35 up. When with VM, I had their router in modem mode and used the MX as the router and firewall. Everything was fine with VM and I got full speeds. When I moved to BT, I connected the MX direct to the ONT – the router doesn’t have a modem/bypass function – you just go direct to the ONT. When I noticed the reduced speeds direct to the ONT, I unplugged the MX from the ONT, reconnected BT’s router and plugged in a laptop and ran some speed test, all of which showed full speeds (900/110). Any ideas on what may be causing the reduced speeds through the MX? Many thanks!
