Any techy network guru's about need some help?

Am having a bit of an issue with my home network.

I have bt total broadband with WiFi disks hybrid connect smart hub 2 which all worked a treat.

I also have a ethernet connection to an outbuilding we have where I am using a Dlink dir-1960 mesh router as an access point by changing the IP address.

With the wife working from home & now both my boys have x box PlayStation etc to ease WiFi usage I bought a 24 port unmanaged switch & I have installed a wired network to all rooms as well as wired connections to gaming devices wife's desk etc.
Since I have installed this some devices show they are connected for instance say my firestick will load the BBC iPlayer app but it wont play any content.
When I checked network I noticed the dns server address was the same as the IP address I use down the workshop & if I try to change the IP address the DNS server changes to that IP address too.

If I disconnect the workshop ethernet from my smart hub everything in my home network works perfectly but of course I dont have any Internet down in the workshop.

Any help would be greatly appreciated.

Cheers fellow mooners
 
I can't speak for the Dlink, but my Asus acted as a DHCP server and you had to set the DNS resolver(s) in the config. By default it was just its own IP address.
 
I don't know the BT Smart Hub or the DLINK Router at all - does that operate as an ADSL router and on the inside of the network serve DHCP addresses and DNS to all of your house devices? It could be that the DLINK device is also responding to DHCP requests and allocating DHCP addresses and details like where to route DNS requests which some of your other devices are picking up?

You could try (as a start) turning off DHCP & DNS on the DLINK router, connect it up and see whether it stops the issue in the rest of the house. Moving on from that would depend on the results and the flexibility of the DLINK Router.
 
Sounds like you are running into some double Nat issues.

why do you have a dlink mesh router in the outbuilding and then different BT devices in the home, or was that the old setup?

basically from the sounds of it the router in your house and the router in the outbuilding are both trying to NAT

personally I would just run one system for everything, as that would be easier to maintain and troubleshoot going forwards

we are with Vodafone and have their crap router installed with WiFi turned off and it’s basically just doing the NAT etc

into that we have 3 deco mesh nodes around the house, with the main one plugged into the router and an Ethernet back channel to the one in my gaming room / office. The rooms with a lot of devices in school have small unmanaged switches plugged into them and it all works fine - they are in access point mode only. This gives me wired in the rooms I’d use it (living room and office), and strong WiFi in every room of the house & garden.

With your current setup I’d say you probably want :

Main modem / router acting as dhcp / Nat, with wireless off
WiFi discs around house in access point mode
24 port unmanaged switch plugged into main router
Outbuilding router access point mode and dhcp, NAT, dns, all disabled. WiFi on if you’re using wireless devices down there

that way everything goes through and is configured by the main router, discs rebroadcast the WiFi and the outbuilding is in the same infrastructure and not competing with any other hardware

if you had a system like deco then instead of using the dlink device then you could just use an additional unit down there and use the Ethernet backhaul - in fact can you not do that with the bt discs and just put another in there? Google says they have Ethernet ports?

Thanks for the replies everyone.

I know explaining what I have sounds complicated but it makes sense to me basically the house is all BT & the workshop has its own network through the d link while still able to connect remotely from the house if I need to.

the workshop is too far away from the house to connect to via wifi & I do use some devices connected via ethernet to the D-link router the house has all the BT devices & the 24 port switch is connected to port 1 on the smart hub 2 port is workshop & I have an ethernet connected to the kitchen which goes into port 3 its a but rubbish they only have 3 ethernet ports to work with.

Outbuilding router access point mode and dhcp, NAT, dns, all disabled. WiFi on if you’re using wireless devices down there

I'll do all that it doesn't have access point mode as per but changing IP address I was told does the same thing I should still have connection through the ethernet ports shouldn't I?
 
i had similar issues i bought a couple of cheap Huawei wifi 6 routers recently which you can connect together, thinking i could use them as access points, from my pfsense router, but no the firmware is so restrictive it wont work as an access point it insists on creating its own network. i think you might need to ditch the router and get a proper access point. One last thing to try though is to plug your Ethernet cable from the house to one of the lan ports rather than the single WAN port on the dlink router.

Disabling DHCP on the D-Link should essentially put it in access point mode and may well sort your problem out. If you’re able to connect to the internet through it and it’s just causing conflicts with devices in the house, that would be my bet. With DHCP disabled, all the routing and IP assigning will be done on the main router in the house.
 
Thanks guys turning off DHCP did the trick(y)

Still learning bit by bit I always though you had to have DHCP on to allocate ip addresses but the smart hub 2 would do that so the access point doesn't need to makes sense now.

Another problem solved thanks to my fellow mooners very much appreciated thank you (y)
