Since migrating my home network from a Linksys router to a TP-Link BE9300 (Wi-Fi 7) as the main router, I have been experiencing severe and persistent internet connectivity issues.

Current network topology

• TP-Link BE9300 – main router (routing/NAT enabled)

• Deco M4R #1 – connected directly to the BE9300 (same room)

• Deco M4R #2 – located in the living room (~9 meters away)

• RE315 repeaters (x2) – approximately 10 meters from the main router

• RE505X – located in a separate room

• Goal: cover basement and main floor

Problem description

Since this setup was deployed:

• Internet connectivity is unstable

• Deco units stop functioning every ~2 hours

• When the issue occurs:

  • Wi-Fi clients can no longer connect

  • Deco devices appear online but enter a loop / become unresponsive

  • Only a reboot temporarily restores connectivity

• The issue repeats consistently and predictably

Additional observations

• These problems did not exist with the previous Linksys router

• The instability occurs regardless of client device type

• The behavior suggests issues with:

  • mesh coordination

  • routing/NAT interaction

  • or firmware stability when multiple TP-Link mesh/extender devices are present

Impact

The network is currently not reliable for daily use, as Wi-Fi connectivity drops multiple times per day and requires manual intervention.

I am requesting:

• clarification on supported topologies for BE9300 + Deco + range extenders

• confirmation whether this mixed setup is officially supported

• guidance on required configuration changes or

• confirmation of a known firmware issue

At this point, the experience has been significantly worse than with my previous Linksys setup.
