I have Virgin broadband installed and recently upgraded to their 1gig service. Yes a total overkill I know. But hey I got the upgrade for 'nothing' (well to extend my contract with them).
Anyway I understand there is an issue with Virgin broadband and UDP which causes issues such as Microsoft teams to freeze momentarily. A 'fix' (well actually to improve the situation) is to put the supplied router into Modem mode and use a 3rd party router. Of course I do this anyway with my Linksys WRT32x. It appears this makes things far better (which it does) but not 100% as we still get occasionally Teams freezing issues.
Anyway firstly has anyone had similar issue and has (if possible) setting up QoS for Teams helped in OpenWRT. Or are there any other tweaks within OpenWRT that may help the situation with UDP?
You should count yourself lucky then. It is something that is being reported on the Virgin community forum and seems widespread. . I wouldnt make a statement like that if I hadnt investigated it first.
I provide IT support within the NHS. The VPN requirement has expanded greatly due to lock down and the NHS has also rolled out Teams as a secure a/v solution. But getting loads of people using VPN links (which obviously is needed as there is secure patient data) and also using Teams through it kiled the link. So the rule is if you want to Team dont VPN
