Modem

Hi all I'm having a very annoying issue which came out of nowhere. I'm connected to my modem by ethernet with my laptop, and all of a sudden today when I came home, everything looked normal, all the lights were flashing, the ethernet sends and receives packets, but can't connect to anything...

Can't afford cable & have a laptop but no internet access. No HDTV but its digital. How can I watch just regular channels if I can?? Help!!

HI ! i need a router with good speed , 2.5 and 5.00 ghz freq. supported and my budget is around 70$. PLEASE HELP !!!

how do you setup for a wireless connection using wi-fi and my home modem. its a toshiba satelite 5500 laptop

How do you get a pasword if you set up a Motorola modem with push button wpa? Now I want to connect a tablet that does not support push button. How do i get a password?

Iset this up with wpa push button , now I need to add a tablet but it wont use push button. Ity wants a password, but I never had one? ! what can I do to get a tablet connected?

The problem is i tried yo install a 3g modem and i found the memory in the laptop was not sufficient.so i removed the modem and tried to stop the installation process.it asked me to restart.i presssed forced restart.after that the laptop showed me logging off for some hours.so i left the system...

I desperately need to know why this one laptop is not able to connect to the Internet even though my phone is connected to same modem, as is family computer downstairs.... Thank you :)
