Hello. Plex works fine on my own home network. It also works fine for me remotely on my phone when on LTE and wifi elsewhere. My father-in-law uses my account. We changed his router to get rid of the router he was leasing from his ISP. Ever since we switched routers at his house Plex continuously buffers. Plex plays for a few seconds and buffers, plays for a few seconds and buffers. I put the quality all the way down to 720kb/s and it still buffers. It worked fine on his older router. He is hard wired in to his router and using a Roku 2. My upload speed where the media server is located is 5.5Mb/s. My father-in-laws download speed is 40Mb/s - 60Mb/s. He is using a Netgear N600 router. Any ideas would be appreciated. Thanks.
