I'd start by having both of you do a speed test (preferable to the same server) - one that provides not only up and down speed but also measures jitter. That may lead to seeing one person with speed / jitter issues over another. I've seen it here in Canada where updating a modem has resolved similar problems (see https://communityforums.rogers.com/t5/In...647#M32690 ) which references jitter as it applies to the gaming community, but specifically addresses the issue of internet modems & firmware versions. Hope this helps...
