High Ping on some servers located in the same place



I am getting a weird issue with the Mumbai 2 server. Please look at the screenshot below :


I am getting 100+ ms on Mumbai 2 server when connected via a LAN wire from my router to PC directly. But when connected via Wi-Fi , the ping comes to 5-10 but I get ping spikes. So in both the cases its unplayable to play on Mumbai 2 servers. I have contacted my ISP and there’s no issue from his side. Would be great if you can assist me with this. Thanks.
