Internet dropping lease renewing

[Arecz]

Hi. After switching from BT ot SKY, I`m now seeing Internet drops out, just now after last nights. With BT I had no issues. So must be with SKY router or ???

Here are my logs. What`s going on? (Had to remove repetions in log as repeated too many times)

I've only been in sky for 4 days. What's the time to quit?

@Arecz 

At what time did you see a drop? Your logs dont show any drop

[Mr+Slant]

All those entries are perfectly normal.

Sky issues a 1 hour DHCP lease on IPv4 and IPv6 public addresses so every 30 minutes or so you should see the IPv4 and IPv6 leases being renewed, which is what your log shows.

Why use DHCP, why not use a static address instead. Something is occurring here with the lease renewal and causing the network to drop out. Can Sky answer the following please:

1. is the ARP table of the ISP WAN router set to time out? If the answer is yes, then every time a lease renewal takes place the MAC table has to be re-populated, adding delays.

2. The logs mention ACS, is this referring to Cisco authentication? The re-authentication process is another area which will be adding delays.

Sky broadband used to be stable, but this is becoming increasingly frustrating, to the point where we are considering switching over to either Virgin or BT Fiber, which has just been laid in our area.

I am also seeing lease renewal impacting connection to web services (dropping out)

my log today matches drops:

2023-1####1:35:24 syslog: WAN IPV6 UP
2023-1####1:45:42 syslog: Lease renewed 3600 ip ######## (can suppply as a DM)
