Ask your neighbours to move their Router to the outside wall closest to you? that is about the max you can expect from us...

Better antennae on the Router is unlikely to happen
Wiring to their Router is unlikely to happen
Purchase a re-broadcast Router you can possibly strengthen the signal with

Move into their house, maybe?

In my laptop I'm using Intel® PROSet/Wireless program, and I have changed some configurations, and then my wireless connection is better then before.
But the program I'm using is in Turkish, the original was in English. Now let me try to translate into English.

If you are using Intel® PROSet/Wireless program you can do the followings.
1. From the Tools menu select Adapter Settings.
2. From the left listbox select Device to device power management. At right side default value is "disabled" change it to noisy environment.
3. From the listbox select Forced Browsing. Right side slide the gauge bar/progressbar to the maximum .
4. From the listbox select Sending Power. Right side slide the gauge bar/progressbar to the maximum .
5. From the listbox select Power Management. Slide the gauge bar/progressbar to the maximum .
6. From the listbox select HD mode. Change the value to "Activate".
7. From the listbox Data Transfer Improvement. Change the value to "Activate".

With these 7 options, your wireless signal could be better.
If you don't have the Intel® PROSet/Wireless program, you can download it from http://www.intel.com/network/connectivity/...et_software.htm

Note: I have translated into English, so some words may not be equal.

Oh, thanks. This is the more appropriate answer found in this topic.

And also you can find the best wireless signal positions by using Network Stumbler program.
Network Stumbler checks the wireless signals every seconds and logs the signals. You can see the best places by analyzing the graphics while you are moving your laptop.
And if you have GPS, Network Stumbler directly says the best position.

You can download Network Stumbler from http://www.netstumbler.com/

Anymore suggestions?

Listen, but I did not find any of those downloading link over there.

First make sure you have a intel wireless card. If you have an intel centrino mobile chipset, chances are, you do.
To check for an intel centrino mobile chipset, there's probably a sticker that says it on your computer, If not,

Go to control panel ->network connections -> wireless network connection -> properties.

To download the intel software, go to the website -> http://downloadcenter.intel.com/default.aspx
then go the wireless link on the left -> Wifi products -> Whichever card you have(assuming you have an intel card -> select operating system -> then download the
Intel® PROSet/Wireless Network Connection Software for whichever card you have (still assuming you have an intel card.

When you click the link I specified before http://www.intel.com/network/connectivity/...et_software.htm
You will see 4 tabs at the middle top. Click "Tools & Software".
You will see 2 new links. Click Intel® PROSet/Wireless Software Download

Or directly click here http://support.intel.com/support/wireless/...b/CS-010623.htm

In the new page download the product which matches your adapter.
