Poor wireless speed/signal - help!

[Tombles]

Hi All

I'm a beginner when it comes to networking. I have recently moved into my house with VM 200mb set up in my office (the VM Super Hub 2 is wired in here). I have a wired connection to my PC within the office but everything else runs over Wi-Fi. I purchased a powerline adaptor with Wi-Fi (Netgear PLW1000) but the speeds in my lounge will only get to about 30mb when I run a speedtest.

Can you recommend what the best solution will be to get good wireless signal and speed in other parts of my house based on a budget up to £150? It will be very difficult to wire up the rest of the house so ideally I need wireless solutions.

I've uploaded an image of my ground floor showing location of office (extension) and my lounge to give you an idea.

Thanks!

Thanks for the suggestions, I've seen the Ubiquiti Access Points but my only concern is how to get the cable from my office to a suitable location, and doing so neatly.

I've tried my powerline in different sockets and it makes no difference, if anything it gets worse. Even though it states 30mb/s it feels much slower, even webpages take a while to load and some videos on Netflix will not load/buffer at all (even the thumbnails might not load).
