Hi Geekzone team,

Have just had my connection with Quic go live!

Having a few issues with certain sites taking a long time to load or not loading at all, I suspect it might be an MTU Issue after crawling the forums here and finding similar issues

I see all the setup pages recommend setting MTU to 1500, however my router (RT-AC59U V2) Only allows me to set a maximum MTU of 1492.

Do I need a new router, or can it be manually overwritten? or ignored completely.

Other troubleshooting I've tried:

Connecting to Quic using either DHCP or PPPoE , both the issue still persists.
DNS servers ( Automatic ISP , Google ,Cloudflare )

Here's a screenshot of my router setup page

Appreciate any help - :)

1492 will work fine - there's no need to raise it to 1500.

Which sites fail to load for you?

Dunedin, NZ
Quic Broadband | Rocket 1G/1G Hyperfibre (Yes, you read that right!)
Dunedin Live Webcam (4K) | Quic Smokepings

That's good news! my connection is failing intermittently on all sites however some seem to be worse than others,

One example is I can't load store.steampowered.com and if it does load its loading as plain http no stylesheets.

Another example, getting a rocksteady connection to geekzone however pinging google is giving intermittent failures:

@itchyfeetleech That's really quite bad. Got another router you can test with?

Also just checking, you don't happen to have a switch between your computer and the router or perhaps using WiFi? I've been pinging your external IP address and it is looking stable at-least externally with 0% packet loss so the problem may be internal for you. As others stated, having a MTU of 1492 should be fine.

Give your router a long-standing ping internally and see if that has issues also.

Unfortunately, I don't have another router I can test with. (Router was working perfectly on previous 2degrees UFB connection)

Not using any network switch + I'm connected via ethernet, can confirm happening across multiple devices.

Internal ping to router looks O.K

Sorry for double reply - using winmtr it looks like the lost connection is happening outside of my network?

Please correct if wrong but that's my understanding of this:

Another update:

Using Cloudflare warp seems to completely fix the issue on my PC.

Anyone have any suggestions for what I could change in router so I don't need to use a VPN or Cloudflare warp to have stable connection?

Can you try running the MTR to 1.1.1.1 and see what you get? (keep this running for a while).

I actually think you should log a fault too. This may not be looked at until tomorrow but it really appears you've done a whole lot of testing to conclude the issue is outside of your network.

Just as another data point, I've got the same path to 8.8.8.8 and my packet loss is between 0.7% and 0.3% after 300 packets.

Hi attached is MTR to 1.1.1.1; this connection like the geekzone one does not go down intermittently.

Still think safe to callout fault?
