Hey guys, so I'm into online gaming, and although I live in India, and most of the games I play are hosted on EU/NA servers, because of this I usually have a ping of about 180 - 190, but after logging on today, and experiencing severe lag, I checked my ping, and it has spiked to about 350-380 ms.

I use a Beetel 450BXI modem + router.

This is after using TCP optimizer optimal settings, any help would be really appreciated, and if you need anything else that would help you understand my problem please let me know.
