Frequent disconnection since change of switch

[Inceptionist]

Some days ago, switch in my area was changed by ISP. Since yesterday, my connections randomly stops working and I often have to restart my own router to connect to Internet again.
Is there any issue with my router or with new switch installed by ISP.
Or me rebooting my router is just a coincidence?
Cause sometimes, the connection starts working again without me doing anything.

ask if other users in your area are also facing the same issue.if yes then issue seems to be with switch else try another router.
