While trying to connect a pc to the WRT54G2 wireless broadband router,windows gives me the following message: ''windows cannot find the certificate to log on to the linksys network'.what is the problem with configuration or what should i do to solve the problem.

So, If you have internet connection speed problem with your wireless try with the following steps,
1.)Reset the wireless router by using the power switch on it or by unplugging it and plugging it back in.
2.)Place the wireless router in an ideal location. The higher it is, the better, but don't put it near metal objects.
3.)Get as close as possible to the router with whatever device you're trying to connect.
4.)Keep the router and your connecting device away from other electronics. You should especially keep away from phones, fax machines and microwaves. etc.,
5.)Adjust the Wifi antenna if it has one.
6.)Change the router's channel, especially if other wireless routers are nearby.Following these steps would give you stable internet connection and also increased speed in connection. You can check your internet speed from www.ScanMySpeed.Com before and after following these steps.

Hi

The Router configuration is not that much difficult, only few thing you have sure,
1) Correct ADSL Connection User name & password,
2) Chose unique ip address in All host.

Follow the mention bellow instruction to configure and connect to Wifi Router,

• Plug the network cable ( Mine was Blue ) which comes with the Router Box pack to your computer. The other end goes into any of the Router Ethernet Port ( 1 or 2 or 3 or 4 )
• Now type in 192.168.1.1 in IE or Firefox or any browser. You will prompted for password which is admin. You must be logged into Linksys Router.
• Now since your ADSL modem is also having the same IP , we will change the IP address for WRT54G2 Router to 192.168.5.1
• Under Setup >Basic Setup look for Network Setup and Change Router IP. Change to 192.168.5.1 and Save changes.
• Since the IP has changed you will need to close the Browser.
• Sometimes the IP doesnt change automatically. Do a IPCONFIG / RELEASE and then IPCONFIG / Renew

Replace it with a new one.

its possible that the wireless card does not have the correct wireless settings.

Open the linksys wireless monitor on your wife's laptop.
Go to the profiles tab, highlight the default SSID then click on edit at the bottom. It will search for the wireless network, from the list of networks that it will show you, click the name of your wireless network, in if the network is secured you will be ask to put in your network key. Then click connect. Then it will say that you profile was successfully configured. then click connect to network. It will take you back back to the screen where you saw no association to the access point, check if you will now get a new message. On that same screen click the more info button at the upper left hand side. Check the IP address it should be 192.168.1.x. If you have that IP then you can test if you will be albe to get online.

if you still have any problem just reply to this post.

First, you have to be sure your ipaq has wi-fi feature is on and you can check on network connectivity option for any wrong setup there. According to your information, your ipaq is not recognized by your router and I agreed that your router is working normally. Try to reboot your ipaq and be sure to get wi-fi to turn on and try to connect it again. I have my Dell Axim also used Windows Mobile like Ipaq and it connected easily with no issue. The message in your to show me that you need first to identify your ipaq before you you can get it to connect to your network. I hope this help.
