The DG834 series are popular ADSL modem router products from Netgear. The devices can be directly connected to the phone line and establish an ADSL broadband Internet connection to the ISP and share it among several computers via 802.3 Ethernet and (on many models) 802.11b/g wireless data links.
These devices are popular among ISPs as they provide an all in one solution (ADSL modem/router/firewall/switch), which is ideal for home broadband users. The Netgear UK website claims the DG834G is the most popular wireless router in the UK and lists five awards that it has received.[1]
The DG834G is perhaps the most popular product of the series, and has been produced in 5 versions. All versions have Wi-Fi.
The DG834 (without the G suffix) is the same product but without Wi-Fi. Wi-Fi can be added later by plugging in a wireless access point although this then occupies one of the RJ45 ports.
The DG834GT is a similar product - it looks like a DG834G v2 or v3, but has a Broadcom chipset like a DG834G v4 and supports Atheros Super G which can achieve a 108 Mbit/s signaling rate (double that of standard 802.11g). In the United Kingdom, many DG834GT routers were supplied by Sky Broadband and are branded with a Sky logo. Sky later supplied a DG934G router, which is a DG834G v3 router in a black case.
The DG834PN model has Wi-Fi but no external antenna. It has 6 internal antennas, and is easily recognised by the blue dome on the top of its case.

Netgear's stock firmware on all products in the series runs Linux. This has led to popularity among computer enthusiasts as it provides a cheaper alternative to a full Linux router. It is possible to place the router in a debug mode using http://192.168.0.1/setup.cgi?todo=debug[2][3] which allows users to connect via telnet directly to its embedded Linux system which uses Busybox to provide some of the functionality. Much of the Netgear firmware is built from open-source software, and Netgear provide this source code [4] and the build system to enable users to reassemble a new firmware image. As a result, various individuals and projects have produced modified firmware which extend the capabilities of the built-in firmware. It is also possible to completely replace the built-in firmware for TI-AR7 and Broadcom chipsets with firmware from other projects, such as OpenWrt.[5] All products except the DG834(G) v5 run on a MIPS architecture CPU, the DG834(G) v5 runs on an ARM architecture CPU.
Only one version produced. White case with a white removable antenna to the rear left of the unit which utilises an RP-SMA connector. N-spec MIMO functionality and inclusion of a Broadcom BCM6348 chipset make this model notable, particularly as the Broadcom chipset offers superior compatibility over the Texas Instruments AR7 chipset (used in the DG834G) with ADSL2+ / LLU lines in the UK, partly due to power spectrum density (PSD) masks applied at the DSLAM.
However it should be noted there is a possible issue with the above chipset when in use on BTW and LLU utilising ADSL 2+ MSAN's made by Huaweii.
