New EE router blocking Home Assistant

madmull2025 — Wed, 01 Apr 2026 20:50:15 GMT

Hello,

I have just upgraded to the new EE wifi 7 hub and extender with a 1.6gbps connection.

Set up was easy and speeds seem good and fairly consistent.,

The problem i am having is that i cannot connect to home assistant via my PC when connected to EE router., It works fine if i use old TP Link Deco mesh system that is still connected. Works fine on my phone,

EE seems to be blocking it for some reason,

On my Deco it recognises my rasberry PI5 running HA as 'Home Assistant' but the EE just recognises it as Rasberry PI5. Furthermore if i connect my PI via EE then my solax inverter doesnt play well and wont send entities to HA, but sorks fine when connected to deco mesh.

Is there a way to stop router 'blocking' connection to HA?

Its a pain having to change connection method on PC just to see HA or make changes.

I'm connecting using a windows 11 PC. Chrome browser. Using homeassistant.local address as always did before.

Thanks in advance

Try setting up Compatible WiFi on the router under Advanced > Wireless Settings (it defaults to 2.4 GHz) & connect your problematic 2.4 GHz devices to that.

Thanks for the reply but i dont think that solves my issues. The PI5 running home assistant is connected to internet via ethernet just fine.. My PC is then ethernet into the EE range extender and working fine but just wont open home assistant web address.

As if ruter is blocking it.

If i plug PI5 into EE routyer then it doesnt get cinnections and data from the Inverter making the HA page useless.

Hope that makes sense,

Thanks

Oh, I thought from using the TP Link Deco mesh it was WiFi connected.

No sorry if wasnt clear.

The deco was just used to get the wifi up to another room without bother of cable routing ethernet so main one connected to fiber and node upstairs with PI5 ethernet to that.

@madmull2025 Is it all just local issue's trying to get to it? have you tried the port command instead off just the IP.

Home Assistant’s primary web interface is accessible via port 8123. This port is used for both the web-based User Interface (WebUI) and the API, and it is standard across most installations, including Home Assistant OS and Supervised versions. Within a local network, you can access it using URLs like http://homeassistant.local:8123 or http://<your_ip>:8123. The choice of 8123 avoids conflicts with common web ports like 80 or 443.

@madmull2025 - if it's any reassurance, I have a Home Assistant install hooked up to my Pro and it's working fine, along with all of my integrations etc.

The PI5 running home assistant is connected to internet via ethernet just fine. My PC is then ethernet into the EE range extender and working fine but just wont open home assistant web address.

I think this ^ might be something to do with it. I can't speak for the lack of inverter data but I've noticed oddities in the past trying to access hosted services on my network from a device that's connected to a Pro Extender. It doesn't affect local access though via the IP address/local hostname i.e. homeassistant.local:8123 works OK for me.

What I've found is that NAT loopback doesn't always work from the extender. This means if I try accessing a server/service on my network using it's publicly accessible IP or hostname e.g. http://myserver.tld or http://<my_broadband_ip_address> then it times out. I don't have the same problem if I use the internal IP of the server. If I then take the connecting device and connect it to the hub, rather than the extender - it works. I've posted about this previously but am struggling to find the thread.

Hoping that gives you some clues/stuff to work with. The loopback issue will be something EE need to fix in firmware, I imagine.

Hi, thanks for the reponse.

I'm not sure what you mean by port command?

What i can confirm is that it is running and connected to internet as such because i can connect via my phone HA app, which is on the EE network

@madmull2025 See the answer from @bobpullen showing you the port command structure as posted above!

Thanks for the reply.

I am struggling to connect to the hub as the wifi just has the one address and as the hub is next to the pc it uses that over wifi, so save turnnng the hub off (which is pointless as i want the speeds im paying for on my pc) it will alsways use that.

I can access via my old deco mesh its just I feel i shouldnt have to change networks each time i want to interact with HA on PC. Rather annoying.

@madmull2025 Thought you said that the PC is Ethernet connected direct and located right next to the EE Pro Hub?

If the PC has a 2.5Gb/s Ethernet port then you should be getting virtually full speed from it assuming the PC is good enough to do those speeds also.

Sorry if not clear.

Thanks @JimM11 and @bobpullen for your replies.

I have managed to sort it,

By unpluggin the ethernet on the PI and connecting to the EE router wilrelessly it now works on PC.

simply when you know how! or try enough things!!

Thanks again
