Hi everyone,

I'm experiencing intermittent internet disconnections with my Deco XE75 setup and I'm hoping someone from TP-Link can help.

**My setup:**
- 1x Deco XE75 (main node, Wi-Fi Router mode)
- 2x Deco XE75 (satellite nodes, connected via LAN)
- 3x Deco M4R (satellite nodes, connected via WiFi backhaul)
- Vodafone cable modem TG6442VF as the upstream device
- Firmware: 1.4.3 Build 20240926 Rel. 38336 (latest official)

**The problem:**
Intermittent connection dropouts happening multiple times per night. The drops are brief — often too short for the Deco to show a red light — but long enough to interrupt all connected devices, both WiFi and wired. I've confirmed with continuous ping logging (timestamped overnight tests) that the dropouts are real and measurable.

**What I've already tried:**
- Switched from Access Point mode to Wi-Fi Router mode (reduced frequency but didn't eliminate)
- Fast Roaming: OFF
- Smart DHCP: OFF
- Set static DHCP reservation on the Vodafone modem for the main Deco
- Confirmed the issue is in the Deco system, not the modem (connection is stable when connected directly to the Vodafone modem)
- Hardware is not overheating

**The ping log shows a suspicious rhythmic pattern** — repeated ~8 second outages roughly every 50 seconds in the early morning hours, suggesting something timer-based is triggering reconnects.

I've seen other threads mentioning a **beta firmware for XE75 V1** that addresses stability issues. Could a moderator please share it with me or point me in the right direction?

@David-TP @Aron_TP — would really appreciate your help here!

Thanks
