Broadband speeds


[link to this post]
 
Is there a 'loss' of speed at a pc if other devices are attached to the router?

I have a 'nominal' 48Mb at the connection point, but all speed tests indicate around 34-36 delivered from the router. Connected is a wireless net (Billion router in use) and a Gigaset A580 VOIP router also plugged in to the Billion.

Question thus is will the wireless net AND the VOIP be reducing my speed even when they are 'idle' - ie no actual wireless traffic or calls in/out?

ISP have had BT re-route me due to a 'hot' exchange which did improve speed but still maxing at 34-36.

Is your connection wired?

Can you run a speedtest from this site and link to the results and a copy of your modem stats may be useful.

You VOIP router does still have some traffic - albeit very, very low when not in use, but no where near enough to make a noticeable impact on speeds.

Thanks, MHC. Speedtest concerned are cabled direct into router. Not sure which stats you want?

Does a wif-fi network pull down speeds at idle ? What sort of drain would the VOIP be causing?

The only things which will pull down speeds are those which are using WAN/Internet connectivity.

VOIP will normally have keep alives - measurably in ten of bits per second (average). There will be an occasional - "I am here" type message to maintain registration.

A WiFi network will not - unless you are providing a BT WiFi hotspot when there could be occasional traffic or a roaming user.


Speedtest from http://www.thinkbroadband.com/speedtest.html

Modem stats: Sync Speed, Max Attainable Speed, attenuations and SNR.

This speedtest is via a Homeplug but is pretty similar to the results of a direct wiring to the router.
Test

Sync Speed 48998
Max Attainable Speed Varies - around 54-58
Attenuations 20.4 down 0 up
SNR. 7.6 down 6.1 up

Plusnet, eh?

Two things spring to mind...
a) Are you being limited by the wrong setting on Plusnet's "current line speed"? This value has been known to get stuck

http://forums.thinkbroadband.com/plusnet/t/4478906-r...

b) What package are you on? That result could happen if you are on one of Plusnet's older 40/20 package.

Do you know the actual phone wire distance from the FTTC or PCP to your house.

This can be significantly longer than both the "crow flies" (point-to-point) distance and the "obvious" road/footpath distance.

In my case, the FTTC is literally 10 Metres from my front door, 40 M to the PCP and another 50 M from the PCP to my front door.

So one would expect the wire length to be around 100 M

But the actual phone wire length is about 300 M, although this was a green-field site when built in 1967.

Thus on an EE 40/10 contract, I get about 37/9.

Between 6 and 700m

I suggest that your length is the likely cause - but ensure your phone line is clean by doing the Quiet Line Tests.

Also, is that distance, clearly an estimate, likely to be accurate, on the basis, say, that your line is all overhead so you can be sure of it; or is it underground etc?

You may find the Google Earth Measuring facilities helpful.

In reply to a post by mikejp:

Homeplugs will affect your speed much more than Wifi or VOIP would.

Use the Ginp Formula to determine if your vdsl2 connection is with or without G.INP.
Divide your IP Profile by your Sync Speed and the answer is 0.9669 (with) or 0.9679 (without)
