Hi Dave
found this for you, as I am not sure if you can do what you want,..

10 tips for improving your wireless network

If Windows ever notifies you about a weak signal, it probably means your connection isn’t as fast or as reliable as it could be. Worse, you might lose your connection entirely in some parts of your home. If you’re looking to improve the signal for your wireless network, try some of these tips for extending your wireless range and improving your wireless network performance.
1. Position your wireless router (or wireless access point) in a central location.When possible, place your wireless router in a central location in your home. If your wireless router is against an outside wall of your home, the signal will be weak on the other side of your home. Don’t worry if you can’t move your wireless router, because there are many other ways to improve your connection.
2. Move the router off the floor and away from walls and metal objects (such as metal file cabinets).Metal, walls, and floors will interfere with your router’s wireless signals. The closer your router is to these obstructions, the more severe the interference, and the weaker your connection will be.
3. Replace your router’s antenna.The antennas supplied with your router are designed to be omni-directional, meaning they broadcast in all directions around the router. If your router is near an outside wall, half of the wireless signals will be sent outside your home, and much of your router’s power will be wasted. Most routers don’t allow you to increase the power output, but you can make better use of the power. Upgrade to a hi-gain antenna that focuses the wireless signals only one direction. You can aim the signal in the direction you need it most.
4. Replace your computer’s wireless network adapter.Wireless network signals must be sent both to and from your computer. Sometimes, your router can broadcast strongly enough to reach your computer, but your computer can’t send signals back to your router. To improve this, replace your laptop’s PC card-based wireless network adapter with a USB network adapter that uses an external antenna. In particular, consider the Hawking Hi-Gain Wireless USB network adapter, which adds an external, hi-gain antenna to your computer and can significantly improve your range.Laptops with built-in wireless typically have excellent antennas and don’t need to have their network adapters upgraded.
5. Add a wireless repeater.Wireless repeaters extend your wireless network range without requiring you to add any wiring. Just place the wireless repeater halfway between your wireless access point and your computer, and you’ll get an instant boost to your wireless signal strength. Check out the wireless repeaters from ViewSonic, D-Link, Linksys, and Buffalo Technology.
6. Change your wireless channel.Wireless routers can broadcast on several different channels, similar to the way radio stations use different channels. In the United States and Canada, these channels are 1, 6, and 11. Just like you’ll sometimes hear interference on one radio station while another is perfectly clear, sometimes one wireless channel is clearer than others. Try changing your wireless router’s channel through your router’s configuration page to see if your signal strength improves. You don’t need to change your computer’s configuration, because it’ll automatically detect the new channel.
7. Reduce wireless interference.If you have cordless phones or other wireless electronics in your home, your computer might not be able to “hear” your router over the noise from the other wireless devices. To quiet the noise, avoid wireless electronics that use the 2.4GHz frequency. Instead, look for cordless phones that use the 5.8GHz or 900MHz frequencies.
8. Update your firmware or your network adapter driver.Router manufacturers regularly make free improvements to their routers. Sometimes, these improvements increase performance. To get the latest firmware updates for your router, visit your router manufacturer’s Web site.Similarly, network adapter vendors occasionally update the software that Windows XP uses to communicate with your network adapter, known as the driver. These updates typically improve performance and reliability. To get the updates, visit Microsoft Update, and then under Select by Type click Hardware, Optional. Install any updates relating to your wireless network adapter. It wouldn’t hurt to install any other updates while you’re visiting Microsoft Update, too.Note When you go to Microsoft Update, you have two options: the Express Install for critical and security updates and Custom Install for high priority and optional updates. You may find more driver updates when you use Custom Install.
9. Pick equipment from a single vendor.While a Linksys router will work with a D-Link network adapter, you often get better performance if you pick a router and network adapter from the same vendor. Some vendors offer a performance boost of up to twice the performance when you choose their hardware: Linksys has the SpeedBooster technology, and D-Link has the 108G enhancement.
10. Upgrade 802.11b devices to 802.11g.802.11b is the most common type of wireless network, but 802.11g is about five times faster. 802.11g is backward-compatible with 802.11b, so you can still use any 802.11b equipment that you have. If you’re using 802.11b and you’re unhappy with the performance, consider replacing your router and network adapters with 802.11g-compatible equipment. If you’re buying new equipment, definitely choose 802.11g.Wireless networks never reach the theoretical bandwidth limits. 802.11b networks typically get 2-5Mbps. 802.11g is usually in the 13-23Mbps range. Belkin’s Pre-N equipment has been measured at 37-42Mbps.


Good Luck yeah

I'll keep this nice and simple Jellybaby.

Yes you can

Yes you can

Yes but not all of them are easily accessible

Best thing to try first is relocating the router, move it around the house and see if it improves, if you have an old house with thick stone walls then it is gonna impact the signal, newer houses with stud walls are better for wireless signals.

The other thing that can make a difference is the channel your router is using especially if there are other wireless networks in range, again, try out a few different channels and see how it goes, no need to change the settings on your laptop as it will automatically pick up whatever channel the router is using.

Most internal wireless cards have an aerial loop, if your card is easily accessible pop the cover off and make sure the aerial loop is still attached to the card, they can occasionally come off which will impact your wireless performance.

Hi Dave
Think it depends how far you are away from ... ''The exchange'' think that's what BT call them, but I ain't too sure
So if you live far away from it then your signal isn't going to be as strong,but I could be wrong on that

that only affects the speed Roo. The wireless/ wifi is an internal thing

ohhhh right sorry
I knew it was something but always thought it was to do with the signal dohhh!
Thanks Mark

If you post in here which model laptop you have i will be able to tell you if the answer is yes or no.
Some are built in to the chipset on the motherboard and can't be changed.
Others are plugin boards.

Also if you live in a house with very thick walls, you are unlikely to improve things.

The most successful thing I have found is to move the wireless channel away from the default 6 and 10, as most people who live near you use those, and that can have an effect on your signal strength if other devices are also using the same frequency.

That is a quick and easy thing to do, and does n't need anything being taken apart.
