Packet Loss

[Danmc07]

I've been having terrible packet loss for many months now. I recently decided to get something done about it after upgrading to Gig 1. It originally started on my Hub 3, now my Hub 5 suffers the same issues.

Within the past 2 weeks I've had 2 engineers out. Both for different reasons but i outlined the packet loss issue to both. showing BQM graphs to them. Both engineers plugged their machine into the line and said there's nothing showing up as a fault so unsure what to suggest.

I upgraded my system to an Ubiquity system this week and even the Ubiquity system is notifying my of packet loss. 

So where do i go from here? I've had 2 engineers both stating my line is fine when clearly it isn't. There must be a fault at the box on the street or something as I've got two feeds coming into my house (one feeds the living room, and one that feeds the bedroom upstairs which is where the Hub is currently). both are having the same issue.

The above image is from my Dream Machine SE clearly stating there's a fault.

type this into google too bro 

[legacy1]

do a night test with the hub in modem mode and a PC with BQM allowed by firewall and run Wireshark with filter:
port 68 or port 67 or arp

then change BQM and Wireshark you arp reply

Hi mate, pretty simple install at the minute. Just a dream machine se with a couple of Ubiquiti U6 Pros (console is hard wired in, but the issue Is present on wireless also). I mentioned all of my other previous routers just to show that it's not a device specific issue. (I've had the dream machine a week or so but had this issue for months on all of my previous routers... Hub 3 in router mode hub 5 in router mode and even an Orbi router). I'll go through all of the suggestions you guys have mentioned and report back 🙂

[Akua_A]

Thank you for your response @Danmc07 

Have you been able to try the great suggestions given by the community? Do you need any further help?

Thanks,

[Danmc07]

Hi @Akua_A,

I've tried suggestions but I'm still receiving packet loss. 

 

[Carley_S]

Thank you for providing this @Danmc07 

Are you still having service issues today as I can see these issues occurred on 27th February? Are you able to post your live BQM link and we'll investigate this further if needed?

[Danmc07]

Hi,

Yes I am. I've had this issue for months..:/

[Steven_L]

Thanks for coming back to us Danmc07, I have looked into your issues and can see that there is a problem with one of your upload channels that would need a technician visit to resolve.

I can arrange the appointment from here but would need to confirm a few details via a private message, that I will drop over in a moment. Please look out for the private message and we can get started.
Kind Regards,
Steven_L
