Need support on disconnections for 6-10seconds every 10min

Its been very annoying to have videoconferences and gaming. Videoconferences lag and gaming disconnects. I tried already:

• Turning off wifi to reduce load on the modem
• Wired connections
• Restarting
• Power cycle for 10min
• Factory Reset

Please help

The connection is fine but every 10min disconnects for 6-10 seconds. This started happening around 12 days ago.
