It sounds like you have multiple dhcp servers running, This is a non-no and while causes issues.

But he was responding to the op who referred to his modem as having weak wifi, therefore correctly stating he most likely had a modem,router,ap combo aka a gateway.

I know people on this sub don't like them, But I used flat ethernet cables to allow me to put an access point (mesh nodes in my case) at each end of my house on the ground floor. They are much easier to route under carpets or around the edges of the walls and through door ways.

Meaning that the upstairs wifi devices generally only have to go through the floor rather than brick walls or chimney breasts and is a much better experience for my family.

I had it with EE, at the time zen and others were selling it. There used to be a list on the openreach website

No, id argue bt is overpriced. But a gfast forecast of 90+ is borderline not worth the extra money imho.

Ive previously had gfast and it was on the low end of the estimates at my address and i fought with disconnections for about a year before openreach finally found a fault. In my experience its Much more more sensitive to issues that superfast.

Yes so that is the gfast product, a lot of providers dont sell it at all, or only do if the property is likely to get 150mbps.

90 is slow for gfast and possibly below a threshold that BT are happy to sell it at.

Is the shell product called ultrafast or superfast?

Just wiring up your existing mesh kit with moca is likely to be the cheapest solution and potentially as good as a full on AP solution with controller.

That 90mbps quote from shell - is it listed as ultrafast (vdsl gfast) as in theory its too fast for a superfast (regular vdsl) connection.

You might be comparing two different openreach products.

In the uk the traditional broadband has been fibre to the cabinet, vdsl. With a max speed of approx 80mbps if you are close to the cabinet, dropping as you get further away.

You are likely getting the best speed vdsl can provide at the property.

Alternatives would be checking if full fibre is now available at the property. This would be the preferred option. Typically upto 1gbps

Virgin media cable is available in major cities and might be an option. Typically upto 1gbps.

You are unlikely to be in a gfast area which offered vdsl upto 300mbps and you needed to be close to the cabinet.

Otherwise an unlimited 5g plan if the property is in a good coverage area.

All will likely cost similar to the overpriced bt vdsl plan.

By the looks of it, it’s worth a try using your isp router. It has the required 2.5gbps and Wi-Fi 6. Also don’t forget you’ll have bandwidth spare for Wi-Fi even if you are maxing out a 1gbps Ethernet connection enabling you to make use of the 1.5gbps service across 2 or more devices.

The internet port is for connecting to your isp, unless you are able to disable the firewall, your connection from your new device will be blocked as seen as external connections. You should disable dhcp server on the second device to avoid ip issues, if you get the internet port working you will like be behind double Nat causing issues with online gaming. If your aim is one network it’s easier to use the lan ports, but still disable the dhcp server on it.
