So, any ideas? .608 is installed. Here is the network status:

Oh great, it just died and after restarting, reconnecting and keeping the hub disabled for a few minutes, it still doesn't work.

At this moment I'm regretting moving to Virgin. The speeds are nice, but the quality of service is some kind of a joke. I can't use any Voip or game, because of latency and lag. Packets are dropped and now this.

The upstream power on channel 1 has increased to 50.3 since the first post. Looks like I will be needing a return path attenuator (?)

 Edit: Also, the RS Errors have stabilized, showing 0 on Post RS.

I've had a technician appointment today. He changed the cable, removed an old splitter outside, installed a 6db attenuator and the power levels are looking great.

However, the problem still persists. Latency spikes every few seconds and packet loss from time to time as seen on the BQM after 4PM, which is when the repair happened.

Could it be an area problem?

Bump

[BobLow]

Area 14 on same hub 3.. Two months on vergin and had nothing but lag spicks.. Then Monday had a power cut now the hub won't connect (Access denied). Called tec help on Monday and they sending someone out ASAP (Friday). Can't watch TV as the channel list is stuck on 16%... Seems strange same problem in the same area.. When I was on the phone to tec he sed there must be a lot of problems in my area this is why I have to wait 5 days.. Beginning to regret moving from sky and looking in to moving back.. If you find out what the lag problem is please let me know it makes my oculus rift unplayable online I just get kicked from games.

Hi MonteXMat,

I've just checked your connection and can see no problems from here.

Your power levels, SNR and area contention are all healthy. The BQM graph you've posted has no packet loss and average latency looks fine.

[MonteXMat]

You've got to be kidding me. "Average latency looks fine"?

How about those spikes? If the latency was fine, then the yellow line should be flat, not exceeding 30 ping.

If the "average latency looks fine", then everything above that average doesn't look fine, does it?

Good luck using VoIP when that 160+ ping spike happens. It's very noticeable even if the spike is lower than that. Also, take a closer look at the graph if you can't see packet loss.

I don't mean to HIJACK your post, but also in Area 14. This is what my BQM looks like 50Mb/s+Phone.

Mine's been that bad it's stopping me from even watching Youtube.
