I have a cable modem which is also a wireless router. I have this modem in my bedroom and the signal is strong in there, but when I go to another room of the house, the signal goes weak. Even in some rooms, the signal is so weak that I cannot have a nice connection, so my Internet connects and disconnects every 30 secs.
How can I amplify my wireless signal? Should I buy some powerful router? Or there is some wireless amplifier stuffs ?
