Broadband G Router
Wireless Operations on the 2.4GHz Band
G routers have been around since June 2003, and have been by far the most popular consumer purchased wireless standard product.
In June of 2003 the IEEE, which is the Institute of Electrical and Electronics Engineers.
An association focused on advancing innovative and technology products related to electricity.
The association operates in more then 160 countries around the world.
IEEE has created and maintained a set of standards widely known as 802.11 family group, which sets the guidelines for wireless local area networks in the 2.4, 3.6 and 5GHz frequency bands.
Wireless G network routers operate on the 802.11g standard.
802.11g was created to combine both the 802.11a and 802.11b wireless standards introduced in September of 1999, and utilize the 2.4GHz frequency for greater signal range.
Manufactured wireless networking hardware built to the new 802.11g specification was fully backward compatible with the older 802.11b wireless products, so your older laptop which sports a built in 802.11b network adapter can operate with new wireless G enabled routers.
Wireless Frequency Bands:
The wireless G network routers 2.4GHz frequency band ranges from 2.412 to 2.484GHz, and is divided into 14 channels 22MHz wide, and spaced 5MHz apart creating channel overlaps.
To avoid interference in the United States caused by an overwhelming usage of electronics operating on the 2.4GHz frequency range, there are only three possible non-overlapping channels in the United States which are usable.
Channels 1, 6, and 11 are best to use. Channels 12 and 13 are disallowed in America, due to regulations.
Try to avoid placing devices operating in the 2.4GHz within 10 ft of your wireless G network router.
FYI: Devices which may interfere with your wireless G network signal includes garage door openers, microwave ovens, cordless phones, and bluetooth devices.
Under best operating conditions your wireless G network router will broadcast a connectable signal approx 125ft indoors and out to a range of 460ft outside with no obstructions.
Wireless G network routers can operate at data transfer rates up to 54Mbps. Although due to error correction and dropped packets, real world transfer speed of around 11Mbps is normal.

Overall, wireless G network products are still widely used and are a great choice for your wireless home network.
If your current wireless enable network equipment is working in great condition and to the same 802.11g specification, then there is no need to upgrade. Enjoy it!
