That could be a DHCP issue (or whatever something similar, but not DHCP, is involved in doing the same job), or firewalling getting in the way at either end. Though I'd expect some consistency in timing. Client requests an IP Server issues one There's an acknowledgement And before the lease expires the client should request an extension. &ou'd expect the client to make this request with a similar time frame each time (e.g. some clients do it at the half-way point). -- uname -rsvp Linux 3.10.0-1160.119.1.el7.x86_64 #1 SMP Tue Jun 4 14:43:51 UTC 2024 x86_64 (yes, this is the output from uname for this PC when I posted) Boilerplate: All unexpected mail to my mailbox is automatically deleted.
