About wi-fi does windows have anything to do with setting up wi-fi? for instance i have a sky broadband netgear box and my computer is windows xp home edition, could i buy a laptop with windows XP,98, 2000 with built in wi-fi.could i pickup wi-fi from the computer to the laptop?

There are lots of router suppliers out there on the internet and via amazon and ebay.

Look for a compatible broadband router, cable?

Wi-Fi included as well Ethernet connections.

All operate to agreed standards, so there should be no problem setting up the router.

Is the Netgear Wi-Fi Management software installed on the computer? If it is, you may have a conflict between Window's built in Wi-Fi Manager and the Netgear Wi-Fi Manager. If it isn't, you may need to install it.
Assuming it isn't, there's links to download the software at the Netgear Global Download Center.

I would default to the most current version, if you're running Windows XP, you may need to install the v2.1, however, I would assume the v3.1 would be backward compatible with XP.
Install the software and follow the prompts that will guide you through the installation/setup.
Now, if the software is already installed, you need to find the program and configure it through that avenue. If that does not fix the issue, you should uninstall the Netgear software, remove the Wi-Fi adapter and reboot the computer. After it completely boots back up, you should either plug in the Wi-Fi adapter, let Windows recognize it and install the drivers, (they should still be in the system even after you uninstalled the software). Once Windows successfully locates and installs the drivers, reboot the computer again, (no need to remove the adapter). Once Windows completely loads again, open Start, Control Panel, and System. On the resulting window, click the hardware tab at the top then click the "Hardware Manager" button in the middle about 1/3 down the window. Click the "+" next to "Network Adapters" and verify that your WN111v2 is indeed installed.
Assuming it is at this point, close out everything but the Control Panel and open "Network Connections". Find the wireless adapter there, (may be listed as "wireless connection2" depending on how many times it's been installed). Right click on the wireless device and select "Show Available Wireless Networks"

Well to start with xp look at the following.
http://support.epson-europe.com/onlineguides/en/sx430sx435w_nwg/html/index.htm

you need to check your router setting first,if its lock then you should unlock it first and then you will get connected with Wi-fi,and you can go into router setting by typing 192.168.1.1 and then it will ask username and password,type "admin" and in iphone your wifi should be on ON mode.

If your wi-fi router is supplied by your internet service provider (they may call it a "gateway") then you can ask their tech support for advice in resolving the issue.
If you have your own router you may want to start by power cycling everything.
Unplug the power cord from your modem, your router, and shutdown your computer (shutdown, not sleep!).
Wait about 15 or 20 seconds then plug in the power cord for the modem. Now, wait about one minute for the modem to fully boot up and settle down.
Next, plug in the power cord to the router and wait 30 seconds to a minute for it to fully boot up and settle down.
Next, turn on your computer and wait for it to fully boot up and settle down.
Try connecting to wi-fi again.
If it doesn't work, move on to the next step:
Open Control Panel/Device manager. Locate "Network adapters' in the list and select the Netgear adapter. A dialog box opens.
In the Netgear adapter dialog box select "Uninstall this device" and click on Yes/OK.
Restart the computer and wait a minute or so while Windows re-installs the adapter.
Now try connecting to wi-fi again.
If that fails, you can try resetting your router to its factory default settings:
Your wireless router has a tiny pinhole somewhere on the rear panel or on one end. It should be labeled "Reset". Bend open a paperclip, push the pointy end of the paperclip firmly into the pinhole and hold it there for 10 or 15 seconds. This will reset the wi-fi router to its default settings. Now, you can set up a fresh password on the router and sign in using the new password on your computer.

DHCP SERVER in Router and DHCP server in Wireless Conflicting - Set WI Fi DHCP router leases to say 192.168.0.10 to 192.168.0.100 and default gateway as 192.168.0.1 and on the router set the router's ip address to 192.168.0.1 make the Wi Fi router address 192,168.0.2 . Set in the router the DHCP address leases to 192.168.0.101 - 192.168.0.254 and default gateway 192.168.0.1 or deactivate one of the dhcp servers and rely on one dhcp server like the routers and then deactivate the wi fi's dhcp server.

Pretty simple. It should be set to auto discovery. As long as the WiFi is working ie switched on you shoyuld find your home network pretty easiily. You do need ot knwo the SSID (the name of the network adn teh pasword. Right click on the wireless icon in teh tray to the bottom right adn show the list of netwoprk sits found. One of those should be yours. Simply 'connect' to the network adn entire the Passphrasethat was preassigned when you set up the network an it should automagically connect.

In Windows XP:
Start/Settings/Printers and Faxes
Right click /Properties
Check Port tab
If the printer port connect to USB, install another instance of printer, connected to WiFi

download firefox for xp and you can prob get it for apple also this should sort out your problem

Youe broadband router is working ok with the broadband cable.So it is configured with the broadband cable.Now,to work with the wireless internet,you have to configured the wi-fi router to work internet.You can see the wi-fi connection but unless & untill you will configure wi-fi router it must not work or if before it was working with the wi-fi then you can check the wi-fi router setting because it might change by mistake.Surely it will work after configurating wi-fi router.
