I work from home for Amazon. For many months now I have had intermittent latency issues with Comcast that cause both calls and chats fo drop. When I do the connection test built into their vpn, it always says there are none. But the problem persists and is now jeopardizing my job. I have had multiple routers, tech.calls and escalations up to corporate with no change other than for a short period after the techs are out here. I bought a new net gear nighthawk router just in case; no difference. Is is possible that having more than one device on my router or having more than one computer at a time running could be the problem? I am desperate for answers. I can’t afford to lose my job. Any input would be appreciated. Thank you.
