I can wholeheartedly attest to this! I bought a tplink and it barely improved it. Then I got a lan adaptor and it still won't pick up a decent signal. I was able to play the Splatoon 2 test fire as well as race online in RMX but I lag like a motherfucker! No it's not my wifi or modem because my PS4, Wii U, PS3, laptop, and Phone can pick up the signal and run smoothly just fine from the same distance.
