what is different router and modem


Hello there,

In networking terms, a router is a Data Communication Equipment (DCE) device which is simply your gateway to the internet and is mostly used by Internet Service Providers (ISPs). A router is an intermediary device which also performs packet routing. It determines the proper path for data to travel between different networks, and forwards data packets to the next device along this path. Essentially, they connect networks together.

A modem, on the other hand, a Modem is a "MOdulator/DEModulator". It modulates an analog carrier signal to encode digital information. In layman terms, subscribers use it to gain internet access in their respective homes and offices. It is also called a Data Termination Equipment (DTE) device which is on the subscriber end of the network.

Hope this helps...

Pay attention to part about 802.11n compatibility?
Perhaps try changing the IEEE standard on the router to 802.11g in the set up pages, as it may be set at 802.11n, which your older wireless card will not see.

As to the acquiring ip address message, try using a static ip address, here's a good guide:-
