Hey all,

 

I'm not 100% certain my issue is due to swapping from PPoE to DHCP, but since I have made the switch I have noticed that some websites just fail to load.  They'll hang for a good minute, then I might be lucky and they'll be fine for a while, then again stop loading.  I'm not noticing any other connectivity problems in other apps, I've been on teams calls and VPN sessions all day today without problems.

 

Some example websites in question: reddit, trademe, stuff will all fail to load during these 'hang' times, but if I visit geekzone, microsoft, google they all load instantaneously while the previous trio of sites still won't load.  This is frustrating and baffling me.  I tried running a ping to reddit.com during one of these freeze times but it shows no issue. 

 

So yeah, wondered if anyone was experiencing similar or has any advice.

 

I'm running an Edgerouter 3 Lite, and that's one reason I haven't switched back to PPoE - I deleted the interface and will have to fiddle with firewall settings again to switch back.  Not a big deal but I haven't found a good time to do that and not disrupt the family again 😆

 

Cheers

Sounds super strange, but smells potentially like MTU to me.

 

Are you running an MTU of 1500 on your WAN/uplink interface?

I had problems with IPv6 on my edgerouter. 

 

I turned that off and DHCP connection has been rock solid since.

Cheers. Turns out I wasn't, it was set to 1508. I have fixed that up and will see how it goes.

Looks like it was MTU 🤦‍♂️Things have been running smoothly since making the change to 1500.  Thanks!

Turning off IPv6 is not a solution. The solution is fixing your configuration which is documented here.

Agree, its not a solution. I went through the docs already but that doesnt stop PEBCAC. 

 

 

 

I also had a 1508 MTU. I will fix my config and try again.
