Communication / Networks: Wi-fi Entry Towards Programmable logic controller

Hi,
My goal was to connect laptop with 1215C PLC wirelessly using TP-LINK TL-MR3020 wireless router, which is wirelessly conected to my ISP router ZXHN H168N.
I managed to connect them, but I had to make additional wireless network using TP-LINK TL-MR3020.
The problem was that I had to connect my laptop to TP-LINK TL-MR3020's network in WISP mode  instead to ZXHN H168N's wireless network, which left me without the Internet on my laptop.
Later I managed to solve the problem by adding D-Link DWA-121 wireless USB adapter  to my laptop, but it is overcomplicated.
I have noticed that is is irelevant  if I use D-Link DWA-121's or laptop's wirelles card in PG/PC interface settings, it works as they are one.
All devices, including PLC, are connected to the sam IP v4 network 192.168.1.xxx, with subnet mask 255.255.255.0
Currently I can connect to the PLC using both D-Link DWA-121 and laptop's wireless cards.
In project's "online access" list TP-LINK TL-MR3020 is missing, only D-Link DWA-121 and laptop's wireless cards ara available (check an attachment).
Is there a way to have both internet and wirelles connection with PLC without using D-Link DWA-121, if yes, which is the simples way to achive it.
Thanks
