After Changing ISP's Red0 Doesn't see Full Bandwidth

To add more, this is the graph showing a history of time to the gateway at my ISP. [image] and to zoom into the week [image] Here is what my LAN speed is directly connected to the gig switch on the firewall according to fast.com [image] Here is what my LAN speed is directly connected to the gig switch on the firewall according to www.speedtest.net, which is hitting a local testing server within like 50 miles of me. [image] I don’t get why this connection is having problems. Like I s…

Did you find the cause for the bandwidth issue? II’m having a similar problem.

II’m having a similar problem.

Hi,
would you kindly disclose a detailed hardware configuration of your IP fire installation?

[dr_techno (Dave Mikeska)]

Looking at what was posted in #1. Looks like ipfire is using a slower dns further away, since the 2nd closer speedtest has a higher ping than the other, which ideally they should be the same or similar ping. The ping shouldn’t double like that with half the distance more.

Hello Pike, Thanks very much for your quick reply. I was mainly interested to know if Eric had found the root cause of his issue. I too suspect my issue may be related to hardware and that it is just a coincident that it happened soon after upgrading to 193. I’ll get back if its not. Thanks again.

So is it an isp change or a change after an update?

[kenzo_ume (James Sly)]

For me its not an ISP change and its not the ISP. Like I said, at this stage I think my bandwidth issue could be hardware related. Something might have failed or be failing. I’m not sure so I’m changing to a similar but different device. I expect we would be hearing from a lot more users if IPFire was causing bandwidth to deteriorate.

What is the network interface that seems to have an issue?

Because I know the newer intel interfaces are having issues being used for the SD-WAN side (red0)

Of course I’ve seen some bad intel builds out there, but they are mostly nvme → 10Gb adapters that are using a pcie 2.0 x8 chip on a pcie3 x4 bus.

Hi Dave, After several days of very degraded download speed, bandwidth is back to normal. So it could be a failing hardware component. The curious thing for me is the upload speed was not affected. Its definitely not the ISP. I eliminated that possibility. Also wondering if there has been any issues with the LightningWireLabs DNS server. I’ll keep investigating.

[dr_techno (Dave Mikeska)]

Well Spain and Portugal have been having major outages and there has been people rerouting server stacks to starlink during that time that caused a lot of infrastructure issues on that side of the internet temporarily in Europe. I would suspect that being the cause of the issues more than anything.

The cause of my issue was indeed hardware related. It was a failing port on a network switch.
