Can't reach the pi from a specific device

[sticklerer]

I have a raspberry pi 3 A+ working fine but i can't reach it from my pc when i try to ping it it's just time out . I can reach it from mine phone but not on my pc . The pi is connecting to a wifi repeater that's connecting to my router and my pc is connecting to the router on wire . It was working fine before .
What should be the problem ?

I suspect you WiFi repeater is creating another network address range or given your pi a new IP address,

I would help to confirm this if you have us the IP address of each device, obtained from the device it's self.

These are local LAN addresses so there is no problem with posting them here.

I didn't thinkd about it but there was a plus AP device (anathor router) in my network and because my brother reconnected everything to the devices and not me i didn't thinkd that maybe he pluged my pc's internet cabel to the new device . So basicly you was right my pc is connecting to the new device but my pi and phone is connecting to the old one and the two router has diferent address range .

Thank you for your help i can solve the problem now
