Router stopped recieving an internet connection all of a sudden. all cables are connected as befour ,

Restart your router (pull power for 10 secs and replace). Wait for the router to reset and reconnect. I have found that internet connections to devices often have difficulties reconnecting from time to time. It may be the issue of automatically assigning IP addresses?

Are you using a router? Do you use cable internet? Try connecting directly the cable directly into your netbook. If you have internet access then the issue may be with your router.

1. Login to router first and verify that the router status via the rj45 cable (ethernet).

Try turning off the router for 30 secs, then power it up again.
Then try connecting a LAN cable from the computer to the router and see if you can connect to the Internet.
If you can connect to the Internet then -
With the LAN cable open a browser and type in the configuration URL and check the Wireless settings, then check and/or the wireless card settings (it should have the router's SSID and encryption settings etc.)
Also install the latest wireless card driver.
Then test the wireless and Internet connection. If this doesn't work -
Next connect the computer with a LAN cable to the cable or DSL modem to see if you can connect to the Internet.
If you cannot get an Internet connection with the LAN cable, contact your ISP and get them to test the connection to your modem.
If the modem and Internet is OK and you still cannot get a wireless connection then the problem could be a faulty wireless router.

The 54 mbps refers to the stream rate from the router to the wireless reciever, the 100-110 kbps you refer to is the connection speed to the internet. These are two different things, if you were transfering files from one pc to another it would transfer at a max speed of 54 mbps. If you connect via a cable it would be 100 mbps. Your internet speed depends on your isp server your downloads will be less than 256kbps, with even less upload speed.
