Question TPlink -Losing network -TL-SG2452

[HanDman]

Hi Folks, I have a TL-SG2452 (48 port). It is directly connected to the Virgin modem with 20 plus connections on the switch.
Router was changed 20 days ago and i upgraded all the cabling to CAT 6.
The PC's connected to the switch keep losing connection (network just drops). If the PC is connected directly to the modem, there is no issue.
There are two TPlink extenders connected, these wont work if they are connected to the switch so need to connect them directly to the virgin modem.
Any ideas why the network would be dropping?

Since that is a managed switch, what does the log on the switch say? What about port statistics?

This is a flat network with one vlan on the switch. a friend asked me too look at it for him. I tested every port last week and it was working. Ill get the log and port stats and get back to you. Thanks
