Broadband speed via wi-fi, router to lap top

Recently gone onto fibre, speed at router via Ethernet cable 21. Speed at lap top via Wi-Fi fluctuates, 3 to 7, sometimes as high as 10. What options are available to me to get an increase in the speed at the lap top ? The router is down stairs and the lap top is in a bedroom, approx. 24ft apart horizontally and 7ft vertically

Move router closer? Add a wireless access point? Does speed improve if the two devices are in the same room?

Moving the router is not really an option, it is as near as it can be now, a wireless access point sounds as if it might be what I need. I have checked the speeds this am and got the following :- Upstairs via w-less 15.1; Against Router via Wireless 20.5 ; Downstairs via Ethernet 21.2.
The upstairs reading is higher than usual, it is usually 4 to 9.
Would a wireless access point strengthen the signal so as to give a higher speed?
Please excuse my lack of knowledge, I am a learner at this, that is why I put the question on the forum

As well as the response that Saffy gave, have you considered the "Devolo" type of device/system?

Some people like them, others don't - but I've always found that they work quite well.

Just plug in the small device near the Router (connecting with an Ethernet Cable) & the other larger device in your Bedroom. You can either connect via cable or WiFi.

I should add that I've provided a link to the "200" series devices, but there are also "500" types as well - although, any complaints that I've seen tend to be directed at the "500" devices!

A wireless access point fed by ethernet cable in the room you want to use wireless would give best, falling back its use HomePlugs as an easier way to get the signal to the wireless access point (there are home plug kits that include a wireless access point)

A final option is something like

which we reviewed at http://www.thinkbroadband.com/hardware/reviews/74-as...

If placed in an ideal location i.e. where it gets a good speed, you can rebroadcast that speed a fair bit further. There are cheaper devices if on a tight budget but the Asus was pretty nice to use

Only by being closer to you than the existing wireless device.

Is the laptop using wireless b, g or n?

Wireless b is always slow, g is better but wireless n is much, much faster. Do both the router and the laptop support it?

With the laptop next to the router what speeds do you get?

How are you measuring the speed?

As a quick rough & ready test, I've just tried a speedtest using a Devolo 200 system, with the Device on the Landing & my Laptop in a bedroom.

Please note that I'm NOT on Fibre but on ADSL+2, also I've got other users switched-on - hence it wasn't a "clean" test.

I achieved 16.6 down & 1.04 up.

Another option is to log-in to the router and set the transmitting channel manually to either 1, 6, or 11. Try each in turn, in case of interference from a neighbours wireless router.

Download InSIDDer http://www.metageek.net/products/inssider/ this takes the guess work out of which channels are free so you can get the best signal.
