Router-modem units allow users to create networks and connect to the Internet safely. Normally the modem is incorporated in the computer or it is pre-defined by the cable or DSL Internet service provider. The wireless router-modem creates the interface between the local area network or LAN and the wide-area network or WAN of the World Wide Web. The wireless cable modem router also filters outgoing and incoming traffic on the basis of the senders’ or recipients’ IP.
Broadband devices offer higher feature complexity and provide a superior number of features in comparison with rather basic wireless DSL modem router units. The difference in features results from the incorporated firewall and the possibility to use the router as a network switch. Thus, the data traffic is secure and intrusion is prevented at multiple levels. In case you have problems with the installation of a wireless router-modem, you should call your cable service provider for technical assistance.
There are several advantages to the combination wireless router-modem. Instead of two units you’ll have just one; there is more space and you don’t have to handle separate usage. The average wireless router-modem user may have some complaints too. For example, in case one of the devices in the combination has functional problems, you won’t be able to use the other one either.
Then, the wireless router-modem is more expensive than if you bought only a router for example, and even replacements are more costly too. Moreover in case you need upgrades, the entire wireless router-modem unit will have to be replaced. If you had two distinct devices, a router and a modem, you may have chosen which to upgrade. Before you purchase a combined ADSL router or a wireless router-modem unit, you should know your needs for an application very well.
