No access to router

I want to thank you both for taking the time to look at helping me however i have now sorted the issue and will explain in a sec but just wanted to answer a few quwstions here for you both

Yes the Bt Router is also my Modem

LAN - LAN so when looking at AP mode on any router its recomended you use LAN PORT (Router1/Modem) to WAN PORT on router 2 however i had very little joy with this as my IP kept setting to 169.86.x.xxx and all internet was lost HOWEVER using LAN to LAN there was still a bridged connection to router1 BT/Modem so i could still access the internet, i also found that LAN - WAN seems to be slower than LAN to LAN

the settings would be for the readyshare, the wireless name/password and turning OFF settings not needed like the DHCP as Router/modem 1 will handle that

The router is indeed a R6220, it was a typo from using my mobile, autocorrect i dont know why

i never expected it to be a router but to be an access point as you have pointed out, i have gone most of my life calling all network devices routers as that is what they all do, i mean ok, to a different extreme but still routes traffic one way or another, please forgive my simple ways

Bt router works well on sky's service, i was able to (a while ago) ssh into it and rewrite some firmware to unlock it, turning it into just another 3rd party modem, far far less droped service unlike skys pile of crap

and the IPv6 "stuff" wasnt a red herring and was actualy the cause of my problem, here is what happned

Even with a IPv4 address set manualy i somehow kept getting a v6 address, after trying many addresses (as post above) to get into the router settings page, i decided to look deeper into my ip settings, i opened up Command Prompt and did the usual IP magic ipconfig, i did send a screenshot with my last post but i dont think it went, this didnt yeald much so i used ipconfig/all which gave me a bit more detail but not enough, so i went to my ethernet adapter settings (this is all on windows 10 BTW) went into properties and unchecked the IPv6 protocal;, THIS GAVE ME ACESS!.

i was able to get into the settings page on the router and adjust the advanced settings and switch off the IPv6 on the router and HEY PRESTO! everything works, i have internet, i have access to my router page for both bt/modem and netgear and i can see all devices aswell, (which made me **bleep** myself when my Kitsound Voice1 (on full volume) said CONNECTED TO YOUR WIFI NETWORK!....)

so i cant realy explaine why it happened the way it did unless the BThub doesnt like ipv6 and its not on as sky doesnt support ipv6 yet

however i still thank you both for taking the time to help
