As you know I use a WRT1200AC V1 flashed with DD-WRT v3.0-r8788 and I have a weird issue that seems to only crop up with games and gaming. My speedtests + download speeds seem to be fine, but when I get into a game (in this case Rocket League) my ping is really bad. For example with a TP-Link Archer C7 router my ping is around 70 on west coast servers and 30-50 on east coast servers, but if I use my WRT1200AC with DD-WRT instead my ping is >110 on west coast servers and >70 on east coast servers which makes the game unplayable due to lag spikes. Any ideas on what I should check to resolve this? I really want to use DD-WRT instead of a stock firmware so if anyone could help me out I would greatly appreciate it.
I did not find the right solution from the internet.
