That is a good starting point - I would suggest using 192.168.1.20 to .200 or similar. Leaving a few empty at both ends. Give teh 2700 a fixed IP of .210 for example.

Make sure the names do not have any trailing spaces either. And you can use fairly simple passwords to start with before ramping them up. However, can I suggest that you try, very briefly with NO password set.

The 2700 does not use IPv6 as far as I know so that may not be an issue.

I would also try without the tplink powerline adaptos....try the routers side by side first just connected via a short LAN cable;

The routers are linking fine through TP link, internet comes through to Router B, and I can access both routers IP address instantly one I'm connected to ROUTER A, using either Wireless or Wired. - The issue is when switching to ROUTER B

Using Wired devices on ROUTER B - are working just fine, no issues - it's just WIFI

So my tests are as follows.

I've just repeated the steps asked

Told Router A to have a pool of 192.168.1.10 - 192.168.1.200 - done
SET ROUTER B as IP 192.168.1.230
Can connect to both routers IP address fine .

SET ROUTER A SSID = HOUSE
SET ROUTER B SSID = KITCHEN
Set password on ROUTER A as 00000000
Set password on ROUTER B as 00000000

Can connect wirelessly to ROUTER A (HOUSE) on LAPTOP and IPHONE
When connecting to ROUTER B (KITCHEN) on LAPTOP and IPHONE, it asks for password.
Enter password 00000000

Invalid password. (Still same symptoms)

Forget ROUTER A (HOUSE)
try to connect to ROUTER B ( KITCHEN) - Failed - invalid password - also fails to connect via laptop.
Reboot ROUTER B ( KITCHEN)
After reboot, IPhone and Laptop can connect to ROUTER B (KITCHEN) - Speedtest, returns good results.
Connect to ROUTER A (HOUSE)
Connected fine, speed test OK.
Connect to ROUTER B (KITCHEN) - FAILED - invalid password on iPhone
Connect to ROUTER B ( KITCHEN) -FAILED - LAPTOP checking network, failed to connect.

Cant connect to ROUTER B, until I reboot ROUTER B - and it connects first time, until I reconnect back to ROUTER A - then I cant connect again to ROUTER B again.

Stumped.

The router that has the internet connection is that one that should have an active DHCP server. Router B in your case. DHCP should be deactivated on the router that does not have the internet connection.

ROUTER A (has the ADSL connection)
DHCP - ENABLED

ROUTER B (is connected to ROUTER A via Cat5 Cable) - no ADSL connection
DHCP - DISABLED

can connect to ROUTER B on first connect - and get intenet
Can then connect to ROUTER A - and get internet
Cannot connect to ROUTER B - ever AGAIN, until I reboot ROUTER B. - then only allows connection until I connect to ROUTER A - then stops again on ALL Wireless devices. Wired is fine.

Does your laptop run a late version of Windows e.g. 7, 8 10?

If so, does what you describe happen with the laptop if you click on the Wifi icon at the right hand end of the task bar and then select the SSID of router B?

Do you have another spare router?

I see ROUTER B when clicking wifi icon, it displays, asks for key, then just says connecting, then, failed to connect (Windows 10)

However, if I reboot ROUTER B, it connects first time on iPhone, laptop etc.. internet fine. Only when moving to ROUTER A, then back to ROUTER B it fails.

Annoyingly, I threw out my old talktalk router, otherwise I would have tried with that.

The firmware version on the 2wire BT router is

System Information

Model: BT2700HGV
Hardware Version: 2701-100589-005
Firmware Version: 6.1.1.48-enh.tm

Just wondering whether to see if I can upgrade firmware, or access deeper settings to change things.

That was the first page I googled. Which I followed, to no avail. It's simply does not like talking to Wifi on ROUTER B, when DHCP is disabled and plugged into ROUTER A.

I've ran out of ideas to try, so this router is going in the bin, and I'm going to get a dedicated Wireless/Wired AP.

I can only assume it's a NAT restriction of some kind, maybe firmware limitation, but can't see a way to downgrade or upgrade the router firmware, so it's the end of the road for me.

It says "Note: The DHCP server on BT firmware v6.1.1.22 cannot be disabled, and so it cannot be used as a WAP."
