Hi all I'm on FTTC 50/20 with an Asus RT-AC68U router. Working from home I'm using a range of videoconferencing services: MS Teams, Zoom, Cisco Jabber and WebEx. All of those services work perfectly except for WebEx. When I connect to a WebEx meeting, I can hear and talk to other participants but I can't see their video and they can't see mine. WebEx gives me an error about low bandwidth, but I have 20Mbps upload and as noted every other videoconferencing service works fine. Speedtest.net shows 48Mbps down and 18Mbps up at all times. I lodged a ticket with WebEx and they ran a series of tests which suggested no connectivity or bandwidth problems. I also tried manually setting MTU to 1472 instead of the default setting based on someone else's solution to a similar problem on Whirlpool - this didn't help. Having been unable to solve the problem, WebEx asked me to raise a ticket with my ISP. Has anyone else come across this problem and found a solution? Also is there a way for me to raise a ticket with TPG without calling them? I don't have time to sit on hold and talk to someone during my workday.
