Hi everyone,

I need some guidance regarding my home network setup, particularly about the compatibility and optimization between my modem and mesh router system.

1. Current Setup:

• Modem: Türk Telekom Zyxel DX3300-T1 VDSL2 Modem (Wi-Fi 6).

• Operating Mode: Modem/Router

• DHCP: Enabled

• UPnP: Enabled

• Firewall: Enabled (IPv4 and IPv6)

• IPv6: Enabled (Dynamic IP)

• NAT: Configured with a maximum NAT session of 20480.

• MTU: 1492

• Mesh System: TP-Link Deco X60 (AX5400, 2-pack)

• Operating Mode: Router (Dynamic IP)

• DHCP: Enabled

• IPv6: Enabled (Dynamic IP)

• MTU: 1500

• HomeShield and UPnP: Enabled

2. Internet Connection:

• ISP: Türk Telekom (VDSL)

• Connection Type: Dynamic IP (no static IP assigned by the ISP)

• Speed Test Results (from Deco App):

• Download: ~100 Mbps

• Upload: ~20 Mbps

3. Questions:

1. Bridge Mode Compatibility:

• If I switch the modem to bridge mode and use the Deco system in PPPoE mode, will this configuration be fully compatible with Türk Telekom’s infrastructure?

• My ISP uses a dynamic IP setup. Will there be any issues with PPPoE over dynamic IP?

2. General Stability and Performance:

• My primary goal is a “set and forget” system. I want the best speed, minimal disconnections, seamless roaming between Deco units, and optimal mesh performance without needing future adjustments. Would keeping the modem in router mode while using Deco as a secondary router with dynamic IP offer better stability than bridge mode and PPPoE?

3. AP Mode Preference:

• I do not wish to use Deco in AP mode, as I want full functionality of the Deco system, including parental controls, QoS, and its firewall capabilities. Would this preference impact the network’s overall performance with the modem in either router or bridge mode?
