The easiest way to build a wireless network in home with your Cable broadband services is by installing an all-in-one device which combines the function of wireless router and cable modem. Why? You just require a single device instead of two which is normally you do with modem plus a wireless router. You just need to plug-in the cable lines to the modem and start configuration, just single device using all-in-one cable modem router.
All-in-one Cable modem router devices are not available in the market as many as those ADSL modem router devices. The following paragraphs show you couple of cable modem wireless routers you can consider for replacing your aging modem provided by your ISP.

- Support legacy wireless security 64-bit and 128-bit WEP encryption
- You can share up to 253 users in single subnet network. You will not have that many users in home right?
Cons:
- Low speed of standard wireless G. You cannot optimize the data rate throughput of your high speed wireless N clients
