Ok, so if that's the case, you have two problems.
Your base WiFi hotspot should be running the network, and the tp link should just be repeating the signal and be on the same network
You need to start there and see what the IP configs are
What's the tp links IP? Hotspot lan IP?
What's your IP when joined to the extended network?
What's your IP when joined directly to the hotspot?
The second part is connecting from outside the network, which requires so config on the hotspot.
First, get the LAN/WLAN squared away
uhm.. i think i will need a more simpler language xD
my ip directly to the hotspot (the modem right?) is 152.167.193.156
my ip at the extended network is 152.167.193.152
"First, get the LAN/WLAN squared away"
what is that?
