Packet loss since maintenance?

[shuurajou]

I'm getting frequent low-level packet loss with spikes of 100% which I observe during playing games like Valorant (which has a packet loss meter). The BQM I've setup confirms this too, though its timing isn't picking up the high 100% spikes often. 

I believe this has started occurring since the 20th of April when scheduled maintenance took place which took out all connections in our street. I could be wrong. I've restarted the router to no avail. The router is running in modem only mode. It's a hub 4. The cable was re-pulled to our home towards the end of last year so shouldn't be an issue there.

Hi shuurajou, thanks for the message and sorry to hear that there has been an issue with the service.

I have checked the area and cannot see any outages. 

Can you confirm if there is still an issue since posting? 

Would you be able to create a BQM here

Kind regards, Chris. 

[shuurajou]

Hi Chris,

Here's a link to the live BQM I shared a screenshot of in my initial post.

The issue is still ongoing today. Though quieter this afternoon. 

Here's graphs over the past week.

Hi shuurajoou, 

Thank you for your repy replies.

We have double checked the service from our side and are detecting no issues with the power levels or specifications. 

Are you using an Ethernet connection on the device? If so, can you please try switching the port that is being used on the Hub?

Let us know if this helps. 

Thanks,

[shuurajou]

Hiya,

Yes I’m using an Ethernet cable. I switched the port to port 4 at 8am this morning. Will see if it improves but BQM seems no different so far. 

[legacy1]

do CMD by wire with

ping -n 200 194.168.4.100

see if you get loss

[shuurajou]

BQM still shows my issue, so I've bought 2 new cables in CAT 6a, shielded, to make sure I can rule that out. Will monitor. 

However, packetlosstest.com moments after changing the cables...
