Intermittent slowness

[Hitch]

My laptop generally runs reasonably fast...
Untill, we changed our BB to fibre with EE.

Now every so often It seems to take an eternity to load web pages, even pretty basic ones like forum pages etc.
It seems to do this for a short while, then a few minuites later it will be virtually instant.

I'm using Chrome. I have uninstalled/reinstalled Chrome...
Updates are all up to date as far as I know.
I did a system restore to a date before the fibre came.

Anything to check....?

The connection does seem a bit slow now and then on all devices, but the laptop issues doesn't always seem to coincide, and even have them when no other devices are being used....

From what I can make out, its on a 2.1GHZ processor, 4gb ram, running Win7....
Wireless in Centrino 1030 N, if that means anything...

Have you tried doing a speedtest ? http://www.speedtest.net/ preferably when it appears to be slow as against when it's normal ?

When you upgraded to fibreoptic did you upgrade the router ?

[Hitch]

When it seems to be slow, it wont even open a speedtest page....

Normally its 36-38 m/s

Router, is the EE fibre supplied Brightbox 2.

Line contention?

Prolly Billygoat would be our best advisor here, though when we first moved in here we had no end of problems with intermittency (I think I just made that word up)
..
Turned out is was the copper pair at the top of the telegraph pole, which once cleaned up solved the problem..


Do you have your telephone line connected via a pole ??

I have been getting this on my PC recently.

Been resetting my router thingy each time.

I think it is to do with Chrome, as that is my preferred browser.

For banking I have to switch to IE, unfortunately, to get all the links to work!!!

You need to narrow it down a bit by removing things from the equation.
Start with the easy, reset all the tech. Router, pc, TV box.
Second try a couple of different browsers.
Third if using WiFi switch to a cable direct to the router.
Try that and see how you get on.

Been round and reset everything now.
Funny you should say that G4U...I will try using a different browser next time it happens- Chrome is the only one I tend to use.

See how it goes.

As above!

Find out if it's the laptop or the broadband would be the best method. When it's going slow, try using a phone or tablet if you have one. Does that do the same?

How many computers/devices have you got attached to your router? Any kids with computers.....??

I ask, as 9 times out of 10 you can usually lay the blame at their feet. Two causes:

1. They are uploading monumental amount of files, videos, gaming, etc. When the UPLOAD is saturated, the download will suffer BADLY. The reason being, is that it can't get the acknowledgements to the servers to say "more" so the pages will take forever to load, timeout, etc.

2. File sharing. Kids love downloading stuff. Torrents and other sharing applications can open thousands of connections all over the place to get what they need. Most home/free routers are crappy things that get overwhelmed by the sheer amount of things being connected too and slow/crash/drop traffic. Rebooting will fix it, but it'll come back.

It's worth remembering too, that if you are on fibre and constantly turn off/on your modem (Looking at the pictures, it's combined modem and router) then the fibre cab you connect to might think there are stability issues. After so many off/on cycles it will intervene with something called DLM. This will do a number of things:

1. Add interleaving (a way of error checking, which increases the latency of the connection (that ping number grows). If it's 35, there looks to be some on there already).
2. Reduce your connection speed. A slower speed means less errors usually, but it won't fix the issue for you as that's not the cause.

Left on and untouched for a long time, it should recover - just be aware of it!

Still not managed to get to the bottom of this....
Devices on the network, 2 phones,2 Tablets,2 Laptops and a tv and printer.
Never had an issue with the Livebox, same devices.

Happens even when its just one other device being used.

Everythings been reset numerous times now. Brightbox doesn't get turned off.

Tried disabling firewall, downloaded a different browser (firefox) as it was suggested its an issue with Chrome...Removed and reinstalled Chrome...

I get 'Error-connection-reset' or connection timed out with it sometimes...

I have been resetting my BT fibre box of late, not my router, and it seems to improve things for a while.

I have been resetting my BT fibre box of late, not my router

What is one of them then?

I Have BT fibre, but all i have is a BT router.

[gas4you]

Its the Openreach box that plugs into my phone socket, then the wireless router into that.

Other than that I haven't got a clue what it is or does.

BG will hopefully tell me.

[Someone-Else]

oh. I haven't got one of them. I have a big BT socket (bigger than normal) and my router plugs into this via a cable. Yes, perhaps billygoat will enlighten us both.

Sorry, been out at the Bungahell™ wrecking stuff.

Two ways of getting "fibre" broadband....

1. Like S_E using a combined router/VDLS modem like the BT homehub.

It's good because it's all in one box, one power socket and less cables. It also provides some stats that allow you to troubleshoot connection issues (like errors and speed, interleaving, etc).

2. Like me and Hitch, we have an openreach modem (Huawei or ECI) which connects to a router of the ISP's choice. Two boxes, but it means you can reboot the *ROUTER* or change it until the cows come home without any adverse effects to speed. Downsides are they are locked down (unless you have the Huawei, then you can be naughty and unlock it like mine) and require more cables, power, space, etc.

Be wary of constantly restarting the modem Hitch - too many dropped connections and BT's DLM will think there are issues. It can do stuff like:

- Interleaving - it can increase this incrementally to combat connection/re-trasmission issues. The higher it is, the higher your pint/latency. This is bad if you like gaming.

- Speed - it can reduce your connection speed to try and overcome the "drops" in your connection . It doesn't see the on/off/on/off as good. If it's helping, there might either be issues with the modem (unlikely - what is it? There were some early ones that over heated causing odd issues) or your wiring.

Is your phone line quiet when you pick up the handset? Any crackle, hiss, etc? CAn you do a picture or two of the incoming socket, what you've got connected, etc.
