1. Before you conect to the Wi-Fi, make sure that your computer has installed drivers for Wi-Fi. 2. Make sure that Wireless is already open or st-up. 3. Look for the Wi-Fi spot area or zone, if there's no Wi-Fi access on that area you may not connect to Wi-Fi.
no you cannot replace the built-in wi-fi card...
if you try to change the drivers for atheros wi-fi to Broadcam driver, your wi-fi card will not function anymore.... but you can always install another WI-FI card in your laptop... you can buy a USB Adapter or a Cardbus(PCMCIA) adapter for this purpose...if you want your wi-fi signal strenth and range to be higher, you can opt to buy an adapter which comes under N standard....N standard wi-fi adapters are capable of connecting at a speed of more than 300mbps(practically) to any N standard device like router....
First make sure that wi fi switch of your laptop is turn on. Then check that wi fi netowkr adapter driver is installed perfect and enable. Go to device manager and enable wi fi adapter. For check device manager right click on my computer icon then click on property then hardware ->device manager. Then you see all driver list. Then enable wi fi . Also right click on my computer places icon then go to proeprty then you can see your network adapter right click on wi fi adapter then click on "view available wi fi networks." then connect your wi fi . Let me know if you need more assistance.Thanks.
I think it is saying that the wifi "card" is set so that it is not being configured by windows.
Control panel > Network connections
Under LAN or High-speed internet you will see an icon labelled wireless network connection. Right click on this and then click properties. You will see three tabs at the top
General - Wireless Networks - Advanced
Click on wireless networks
There should be a tick-box saying Use windows to configure my wireless network settings. I expect that, in your case, the box is unticked which means that the software supplied by the vendor of the wifi card is configuring the settings. I find that it is usually more reliable to let windows do it.
So tick the box and click OK. You may then have to reboot.
Check if the wi-fi card is properly installed under Device Manager. Go to Start then look for Control Panel on the right pane. Under Control Panel look for System and Maintenance and then click on Device Manager. Now under Device Manager look for Network Adapters and collapse or click the arrow next to it. Check if your wi-fi adapter is installed(10/100 or 10/1000 is your LAN adapter, wi-fi adapters usually indicates something like 802.11x(could be agn or g or b) or the word "wireless". If you don't see anything I mentioned above that means your computer is unable to detect any wi-fi adapters installed. Know if you found a wi-fi adapter but there is a yellow exclamation or question mark, all you have to do is re-install the drivers for your wi-fi adapter(you can download the drivers on the Compaq website for free.)
Check if the wi-fi is disabled or stopped, if you have a bulit in wi-fi adapter on your laptop they have a wi-fi switch on the side or near the function keys(F1, F2, F3 up to F12). Wi-fi button/switch will have a logo or marking of an antenna that has waves coming out of it and there is a LED light that will indicate if its on or off(for Comapaq laptops it's either a blue button at the front, near the function keys or at the front panel on the buttom edge.
If both fails then you may need to contact Compaq for further assistance.
Hope this will help you fixin the wi-fi problems on your laptop.
Not much offered at Compaq's driver site for XP. For the modem driver, try the link below, it says it's for Vista, but it should work. If it doesn't then you will need the make and model of the modem, then go to the manufacturer's site or driverguide.com for the drivers, and the same for the wireless, make and model, manufacturer's site or driver guide. To be honest with you, modems are just about obsolete, unless you have dial up at home, you'll probably never use it.
