Connection slow down

[pierreda]

Hello,

I have a working OpnSense.
I can connect trough Captive portal and I'm authenticated.

Connection is perfect and access to internet is fluent.

But ... after some times, with same connection (connection stay open for a day) speed drop and access to internet is sslloooowwww  :o

If I disconnect and connect again, connection is again fluent ...

Any Idea?

Thanks a lot

Pierre
