No internet access in the whole network after one particular device is connected
Hi,
My network is experiencing Internet loss since the last firmware update. Now 5-10 minutes after a Dell Latitude 3420 with Windows 11 is connected to the network it causes Internet access to crash. It makes no difference if it is connected via ethernet or WiFi. I also have 2 EAP610 APs in my setup, and HikVision Doorcam with indoor station, and some other devices like NAS, and few PCs. I also have VIGI NVR and VIGI Cameras connected to the SG2428P, but I was told that this might be causing the problem and since im just learning on how to use and configure VLANs I have switched the switch off :) Unfortunately that did not provide solution to my problem :(
I had no troubles on the previous firmware - literally no crashes over 3 months of uninterrupted work. How can I troubleshoot my network?
