There are many causes of this, but the most common can be solved by going to the CMOS (BIOS) of your computer and disable the power saving on the ethernet, PCI or wathever where you modem is connected.

Wireless disconnect in sleep mode?


I think that is normal to conserve energy. There are times when it will take the network connections down to conserve energy.

If it is a problem you can always increase the time on the sleep mode or set it to NEVER.

I have a motorola SB5120 modem but no disc for it.How can I make it work?


With this type of modem no type of software will be required to establish a connection to your computer or router. However the modem will still need to be registered with your internet service provider. If you do not have the software to complete the registration process you will need to contact your ISP. The good news is that the registration of the modem should not take more than a few minutes and can be performed over the phone. After the registration has been completed connect the modem to your computer via a Ethernet cable. You may need to perform a hard reset of the modem at this time. To do this turn off your computer and unplug the power cable from your modem. Wait 2 minutes and reconnect the modems power cable. Give the modem another 2 to 5 minutes to reestablish the connection to your ISP. Power back on the computer and you should have internet access.

I hope the information above has helped in some way.

Turn the modem off, or disconnect the AC power.

Turn the modem on, or reconnect the AC power.

The modem will automatically download the latest software from your Internet Service Provider.

Done!
