HI I have a network I am building as a novice, to extend to areas of property with thick walls and out building quite interesting and challenging at the same time, with various old routers to act as range extenders ( easy solution would be to get a whole range of new kit which it may come to ) 

for now however I am using the kit linked in as below , and I appreciate some setting really do need a tweak but 

using an old Archer D2, ( sorry drop down search does not feature this model  as it it so old ) TP-Link which is solid and works fine except every time i want to go back in and tweak settings

it wont let me in  to the 192.168.1.1

either by

http://192.168.1.1

or by

https://192.168.1.1

Laptop wifi = off

laptop firewall = off

lan cable from laptop to router LAN port

change adapter setting to ip address, still no use...

the only way back in every time ( of this there has been many ) is to paperclip hard reset

whicn is OK but a real pain , as I lose all the previous settings

where am i going wrong please, how to log in every time to tweak

using this rudimentary schematic illustration, it all works fine , except i know i need to make a tweak somewhere as occasionally the TP-Link it falls over for no reason apparent to me 

hence my seeking and tweaking :) Rgs Wi-Fried-Freddy
