Connection started dropping out
Hello, my ISP recently switched my modem for a router with modem capabilities. I plugged my Deco into it with the Wi-Fi router mode and it was working fine. I also immediately updated both of my Decos to the newest 1.8.0 firmware.
It's all mostly fine but I noticed I had trouble resetting my other Deco (both M4s) - the connection from the main Deco seemed to be worse? The other Deco was in the same place as previously.
But the worst part is the connection keeps dropping out, like the Wi-Fi mesh switching between Decos is too pushy, and it switches to the other one where it barely has any signal and my internet stops working for a few seconds.
I assumed first it might be because of my new ISP router but I changed the range of DHCP to only 1 IP so it wouldn't assign any other IPs besides main Deco, I also disabled Wi-Fi on it and only the main Deco is connected via ethernet to it.
I assume it must be something to do with the new update then?
Any help? Thank you!

Hi, have you tried to change the ISP gateway back to the default DHCP settings, then set the Deco into "Access Point mode":
How to set up Deco to work in Access Point mode
Wait for your reply.
Best regards.

@David-TP different ethernet cable didnt help. i looked into deco logs and found this:
**Problem:** MacBook randomly disconnecting due to aggressive band steering
**Device:** MacBook (MAC: XX:XX:XX:XX:XX:XX) in room next to router
**Setup:** 2x Deco M4 units (one upstairs, one downstairs)

### **Additional Context:**
- **Total disconnection events:** 46 in one day
- **Reconnection time:** 6-7 seconds (indicating band steering issue, not signal problem)
- **Channel usage:** MacBook consistently on Channel 44 (5GHz)
- **Device location:** MacBook in room adjacent to router with strong signal
**Summary:** The band steering algorithm is causing unnecessary disconnections by constantly trying to optimize connections between bands and access points. The MacBook reconnects quickly, confirming this is an algorithm issue rather than a signal strength problem.

i think its maybe worth noting i have the wifi set to have both 5ghz and 2.4ghz, not separately? and theres no connection dropouts on isp's end
