I just moved and needed to extend wifi through to my study. I chose to pick up two TP-Link Deco M5s, which now give me full bars coverage everywhere I need it with one big issue: Teams video calls, which stall every few seconds.

I have put my Hub 3 in modem mode, and have one 1 wired via ethernet and one upstairs. I have also turned off SIP ALG. these things have helped a lot, if I don't have my video on its reduced to far more intermittent. 

Is there anyway to fix this, or is this an issue between Virgin and these hubs? Should I return them and find something better suited? 

Thanks
