Try pulling out and putting back in place the ram modules, the motherboard can be faulty.

Unplugging the wireless router and connecting it again should not have altered the wireless connection/configuration. You have connected the cables correctly because the Internet works when you connect a LAN cable to the router.
The Linksys wireless configuration or the wireless card configuration in the computer was changed it to lose the wireless connection. The wireless card configuration needs to be changed to match the wireless router's settings or change the Linksys with new configuration settings and configure the wireless card accordingly.

1gb ram will speed up your access memory you will notice it a little faster when going from web site to web site but to really speed it up you need a faster prossesor or / and better broadband

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.

If the fan does not spin, the unit is shutting down to protect the processor. I would have the fan replaced . Do not attempt to use the laptop, it may cause extensive damage if it overheats.

r u configure the ipaddress to the wireless router

Hi!

Try these steps:

1. Make sure the wireless is disabled when you're doing that. It might cause a confusion between the wired and wireless connection.
2. Try to plug it at other ports (1-4)
3. Try another known working ethernet or CAT-5 cable.
4. Set the laptop's LAN card's speed to 10-hald duplex.

Try these and hope it will help you ;-)

first of all check this battary with another same configured laptop of your's.. i guess this problem should be with your battary...
