Hi Wagstaff, thanks for helping me out.

5pm > came home from work. At this time I did not turn my laptop on as I knew I was going to do some testing.

On the network a VoIP call was made from one extension to another for around 1 hour 20 minutes. This was just to test whether VoIP was also affecting it.

Then at 10pm I started using my laptop and have been doing so for the remainder of the night. But the spikes seem smaller when the computer joined the network at 10pm?

I think the spikes were more concentrated between 10pm and midnight.
When you refer to your computer, am I right in thinking that the computer and the laptop are one and the same thing.
I've been trying to work out why you need a gigabit switch. Is it possible to post a network diagram to show how all your bits of equipment connect together?

BTW does your computer/laptop have a firewall?

Wagstaff

There you go:

By the way, where the Gigabit switch is, there is alot more stuff plugged in there but I have taken it out so it's not affecting it.

The IP phones have an internet in cable (for internet obviously) and it acts as a switch and there's another part that goes out to a router.

If you have any other queries, let me know.

Thanks Wag!

Jack

By the way - hitting to bed so wll answer you in the morning.

Thanks again for all your help.

Thanks for the diagram, Jack. How easy it to plug the laptop into "IP Phone 4" and by-pass the router that the laptop is currently plugged into?

It does look from the BQM data that things quietened down after you went to bed.
When you switch off the laptop, are there any other bits of equipment that you power down?

Wagstaff

Hi Wag,

Woke up today at 8am, read your post and done just that. It's connected to the IP Phone you mentioned and there was no internet activity today. I left my laptop on from 8am and it's currently still connected (via IP phone 4).

There's no other pieces of equipment I power down.

BTW: As of 4pm today, I have disconnected IP phone main internet cable for it's connectivity and plugged directly into laptop. This should eliminate IP Phone 4.

Thanks again,
Jack

It's was interesting to learn that there was no internet activity today from your end, and yet there were spikes throughout the day, with the laptop switched on.
One occurred at about the time you wrote your last post - and there was a lot of activity at about 3pm.

So where are we now. You've taken the Netgear router and IP Phone 4 out of the line. Therefore the current situation is :-

MacBook (Laptop) > 8-port PoE Switch > Linksys Router > 8-port Gigabit Switch > WAG354G Modem > Master Socket.

I think I've asked you this before, but does the laptop have a firewall? Because, I'm just wondering whether you should by-pass the router and switches and plug the laptop into the modem, and let it sit there for a couple of hours. Can you live with that? Only the laptop and modem on the line.

Hi Wag,

My MacBook does have a firewall although it's been disabled for several months now.

I'm actually lying to you when saying that's all which is on the network. We run a hotel like business and the Gigabit switch (which is connected after the 1st router) has 5 connections going to rooms which are routers. I'm going to check the firewall on them routers now.

I plugged all ethernet connections out from the modem at 7.12pm to 8.30pm. Is the ping level normal for that time? Nothing was plugged in. Plugged back only what you see on the diagram as of 8.45pm (I took out the room connections).

Thanks wag,

Jack

It was reasonably flat between those times, certainly no spikes. And that was with just the modem plugged in?
If you're running that sort of business, it would be impossible to do what I have suggested. So it's a question of looking at the setup of the individual components.
As far as you're aware, is the corresponding firmware and software up-to-date?

Unfortunately, I know nothing about the MacBook. It may be worth asking Apple Support if they can check its configuration - a lot of the recent BQM data does point to that as being the problem unit. You say that you disabled the laptop's firewall, was that because there was contention with other firewalls? Do you have another computer or could you borrow another laptop that you could use as a temporary replacement for the MacBook, just to see if it makes a difference?

Wagstaff

Ok Wagstaff, I can't try it today (I think) however I'll give it a go sometime and let you know how it gets on.

I've just noticed... every time I run a traceroute it never completes. Should it always complete succesfully?

EDIT: In fact, I'm going to plug the laptop in right now with only the modem for 1 hour. I'll see if that does anything.
