Hey,
So we're having some massive disconnection issues at the moment - BT openreach guy came today and said the line's working fine so it's not that... but i opened up the router event logs and found pages and pages of this:
Oct 18 19:33:06 FIREWALL replay check (1 of 2): Protocol: ICMP Src ip: 174.6.78.229 Dst ip: 87.112.5.37 Type: Destination Unreachable Code: Port Unreacheable
Error Oct 18 19:31:10 FIREWALL replay check (1 of 1): Protocol: ICMP Src ip: 96.226.139.113 Dst ip: 87.112.5.37 Type: Destination Unreachable Code: Host Unreacheable
Error Oct 18 19:30:53 FIREWALL icmp check (1 of 1): Protocol: ICMP Src ip: 220.90.158.225 Dst ip: 87.112.5.37 Type: Destination Unreachable Code: Host Unreacheable
Just a few examples. Basically, the broadband and internet lights disappear and we get the connection back in about a minute. But i've googled this and there's a lot of people experiencing it ... but helpfully no solutions thus far. Factory reset the router too, changed all the user names and passwords for the router and nada. Does anyone know how to fix this/ experiencing this too? The BT openreach guy said it could just be a router fault. Firewall settings are on, on the router. Everyone's done virus checks on their computers and no one's infected with anything 😕
Any help would be appreciated!
Alex

No-one knows exactly what those firewall log entries mean.
If anyone uses peer to peer software I recommend configuring the software to only use a sensible number of connections, perhaps 50 or 100 should suffice. If no-one is using P2P programs, then the log messages probably have nothing to do with the cause of the problem. Or the log messages are just related to traffic arriving that was intended for the previous user of your IP address (which should mostly stop within a few minutes after the line disconnects/re-connects).

Hi alexrobmay92,
I've noticed that your line has still had a few drops, looking at the fault it shows that this is due to be resolved by today. I'd keep an eye on your connections to see if they still appear after today.

Not 100% certain on the message you're getting through your router logs, ejs explanation is plausible, if your line is still dropping let us know and we'll look into this further.
