Ethernet v WiFi - How much slower should wireless be?

When I connect my laptop to the Netgear router with an Ethernet cable and run the thinkbroadband speedtest I get 9.2 or 9.3 which is OK for up to 10Mb.  When I use WiFi, even with the laptop about 0.5metres from the Netgear router, I get a speed of 4.2.  I know WiFi is a bit slower than a cable but this much slower?

Re: Ethernet v WiFi - How much slower should wireless be?

In a residential area so think there is not much interference from outside.

Also, speed does not seem to alter when our fridge cuts in or out.

 

Router channel is set to auto - am i naive expecting that to give best result?

Scientific test results

 

The router is a VMDG280 located about 1.5m above floor

The laptop is just below the router - within 1 metre

There is a freezer nearby, but below the level of the router.  There is a radiator through the wall, also below the level of the router.

 

Using thinkbroadband speed test

 

15:17  Auto Channel    4.1 (Freezer on)

15:20  Auto Channel    4.0 (Freezer on)

15:23  Ethernet Cable  9.2 

15:26  Auto Channel    4.1 (Freezer off)

15:29  Channel 1         4.0 (Freezer off)

15:35  Channel 6         4.2 (Freezer off)

15:38  Channel 12       4.0 (Freezer off)

15:41  Auto Channel    4.2 (Freezer off)

 

So, setting channel does not help any.

 

To return to the original question, is a Wireless speed which is 50% of the cable speed typical, normal - given the short range (1 metre) ?

I meant to note that I can see 8 other networks round about, so I reckon my PC is OK

Hi glen_almond,

 

We're unable to guarantee any speed via wireless due to the numerous factors which have to be considered. Can you get hold of a 2nd laptop to test your wireless speeds? What is the make/modem of the wireless adapter inside your laptop and are the drivers up to date?

Re: Ethernet v WiFi - How much slower should wireless be?

What is your link rate? (speed wifi shows on connection).

If it's 45 meg (g) then I dont think your results are that odd.

I would also make websites for them, because the job never seems to require the website to work.
