Eero 6 not playing nicely with TP link ER605

[redpis]

I have a home network where the LAN from the Sagecom router connected into the WAN port of the ER605 and on the LAN side of this I used the 10.10.10.2 range and everything was perfect.

I upgraded to 150mb and had no choice but to accept the eero6, I tried exactly the same configuration as above, the ER605 sees the WAN is connected but it’s as though the eero is blocking traffic and therefore nothing now works on the LAN side of the ER605.

Has anyone any experience on how this can be resolved without resorting to flattening my network and ditching the TP- link gateway.

Update: I didn’t realise that you could adjust manually the DHCP range within the eero from the set options presented, the upshot is the problem is solved and the ER605 has been removed.

Thanks for the community support 👍

Hi Keith,

I have future fibre and had to send the sagecom modem back when the eero6 arrived, I must admit that I haven't tried plugging the ONT directly into the WAN port of the ER605, I'll do that in the morning and see how I get on.

Is the fibre G.Fast or Future Fibre?

Either way, you have an ONT or G.Fast modem. Why not just connect the modem/ONT to the WAN port of the Sagemcom and your ER605 as it was?
