Hello,

I have a 50mb Fibre Optic BB from Vigin. The router (Netgear WNR2000v2 - 300mbs N) is located at the front of my house (which is Victorian and quite long and narrow). The external cable arrives here so not to much choice of location although as its a seperate modem I could try and run a patch lead to bring the actual router closer to the centre of the building but its still going to be in the same room.

My office is down the bottom of the garden about 45m from the house. The wifi signal dies about 5m from the back of the house. In order to boost things I purchased a repeater (Sitecom Wireless Network Range Extender - 300N). This I needed to locate in an upstairs back window to provide enough signal to reach my office.

On my PC I have a dlink DWA-140 USB adapter. This I have run from a USB extension to position in the window of my office closest to the house. My signal is still poor but supposedly I am running at 81mbps.

The issue is that my web access is very slow. It took me 45 minutes to download a 50mb file this morning which from the laptop in the house takes well under 2 mins.

I was hoping someone with more networking knowledge than I can make some suggestions. I have a powerline network but I think the long run to the office is making that slow (and my router only has 10/100 wired connections so bottle neck the potential 200 the powerline might achieve)

Would upgrading the antenna on my extender help? The existing antenna are only 2dbi gain. Where can I get 802.11N antenna from everywhere I look they are B/G.

What about a better network adapter for the PC? What might work? My office is wooden but has foil lined insulation in the walls (28mm Wood, 70mm Insulation, 28mm wood) which is why I have moved the current adapter to the window.

Any suggestions gratefully accepted.

Wireless will always be tricky over distance. You could always try removing one of the 2dbi antenna and replacing it with a high gain directional antenna to punch the signal to the office, possibly have something more directional in the house and the office.

Of course everything changes when you go to wireless N with the different frequency as the dimensions of the antenna need to change.
 
Wireless is so falsely advertised for me. Don't get me wrong, mine works fine but the amount of people who are shocked to hear, "yeah, it's possible, this is just going to be poor no matter what.." is quite substantial.

The fact it's a laptop makes another option pretty useless.
 
The trouble with range extenders is that they instantly half the network speed IIRC. Even a really good 802.11N signal is never the advertised speed anyway, so you are on a hiding to nothing really.

The reality is that you will only ever get the reliable speeds that you want by running a cable to the office building. I know that it seems like a load of hassle but if it's your office then you'll be so glad to have it.
