First, write in front of the words: Today, home routing is moving toward the exaggeration of the shape, the number of antennas is more and more on the road, there is no eight-legged beast, no 3 pounds, you are embarrassed to introduce this to your route. The NETGEAR R7800 from this review is easily confused with the R7500. The two are not only very similar in design, but they are very different in nature. The R7500 was released in 2014 and the R7800 was released in early 2016. It can be said that the specifications The R7800 is closer to the R8500. NETGEAR NETGEAR R7800 AC2600 dual-band high-speed Gigabit wireless router home through the wall King WIFI1099 å“’å“’å“’å“’å“’, blue flame Gatlin Lynx Select direct links As can be seen from the above chart, the R7800 mesh is better than the R7500 and R8000, except that the bandwidth is slightly lower than the R8000. Netgear R7800 Nighthawks X4S routers support 4x4 MU-MIMO technology, 2.4GHz network supports 256-QAM modulation technology, so its 2.4GHz/5GHz network can provide theoretical maximum 800Mbps +1733Mbps, which belongs to AC2600 level products. In the 5G mode, it not only supports 80MHz bandwidth, but also supports 160MHz bandwidth mode, so that the maximum bandwidth can even reach 3466 Mbps. However, in order to distinguish between the R8500 and higher-order products, or if the firmware is not mature, the netware does not open this function in routing, and it is expected that the function can be used afterwards. Second, out of the box: Two big toys at the same time Packaging front On the back of the package, feature description R7800 main features: 1.7GHz, Mu-MIMO, Quad-Stream Wave2 are more practical features Due to the original firmware partition, the router is limited to mainland sales. Actually, in the web page setting, the selection area can be changed to increase the number of signals and channels. Inside the buffer protection carton is this little monster With its angular design, the NETGEAR R7800 feels three-dimensional. The back is still using a large number of cooling holes to enhance the passive cooling effect From left to right are the front LED lighting switch, reset hole, antenna 1, four Lan ports (1G bandwidth) yellow is Wan port, another antenna, power connector, router switch On the left are 2 USB 3.0 interfaces and 2 antenna The right side is the eSATA interface, antenna 3 The intention of the netware is reflected in the antenna interface, and the four antenna interfaces are protected respectively. Four detachable antennas, slightly different in appearance and design, for better broadcast signal The antenna is also marked with the corresponding interface Front lamp array integrates two buttons WPS and wireless switch The antenna has a corresponding interface. It is inferred that the antenna amplification effect is different. This configuration makes the best transmission effect. The port of Wan is particularly yellow, but it is a pity that Lan port does not provide aggregation function. The same weight power adapter The maximum power output is 12v 3.5A power is not small Family portrait router manual warranty book power adapter NETGEAR R7800 Vs ASUS ac68u Third, performance evaluation The main specifications: Network SoC: Qualcomm Atheros IPQ8065 1.7GHz Dual Core Wireless Network Chip: Qualcomm Atheros QCA9984 x 2 Wired network chip: Qualcomm Atheros QCA8337 Antenna: 0.41dBi (2.4GHz), 0.91dBi (5.18GHz to 5.24GHz), 1.61dBi (5.745GHz to 5.825GHz), and detachable wired network: 10/100/1000Mbps x 5 Wireless network: 802.11 a/b/g/n/ac, 4T4R Memory: DDR3 512MB ROM: 128MB Wireless network: 802.11 a/b/g/n/ac, 4T4R others: USB 3.0 x 2, eSATA x 1, WPS button, Wi-Fi switch button, LED indicator Switch size: 185 x 185 x 41 (mm) For a more complete comparison of the performance of the NETGEAR R7800, the previously purchased ASUS ac68u was selected as a reference. 1.Rate of USB interface and eSATA interface under R7800 router wired condition Frankly speaking, 1.7GHz dual-core routers at this stage, aside from the recently unveiled ASUS GT AC-5300, NETGEAR R9000 and other non-conventional products, the processing capacity can indeed theoretically put the mass route friction on the ground Although the Qualcomm Atheros IPQ8065 solution used in the R7800 is not yet able to flash Meilin and DDWRT firmware, there are still niche LEDEs and OPs that can be swiped. On the other hand, SoC performance affects NAT forwarding capabilities, QoS rules, and USB transmission capabilities, so a high-frequency core is necessary for increasingly complex network applications, but not only the high-end routing firmware design is also The key factor of SoC output capability. To do this, first upgrade the Netware R7800 Nighthawk X4S firmware from 1.0.2.12 to the latest 1.0.2.28. This test first through the USB3.0 interface hard drive connected to the computer, the first test in the USB3.0 hard disk box to what extent should be able to affect the test results are as follows: In order to test the speed of the eSata interface, we have come to the market to support the ORICA 2598SUS3, which is not a lot of eSata mobile hard disk drives. In fact, the eSata interface hard drive is very inconvenient, because the eSata interface can not directly supply power, so at the same time also plug in the USB3.0 interface as a special To use power, it is inconvenient to use one hard disk while occupying two interfaces, which also affects the appearance. Test Results: From the above table, it can be found that the start of the same type of test QoS has a direct impact on transmission performance. Although the R7800 uses a 1.7 dual-core processor, QoS still occupies a part of CPU resources and affects the actual transmission efficiency. Second, the eSata interface does not significantly improve the R7800's transmission performance. The increase is limited. Of course, it may also be related to the HDD chip. However, because of the aesthetic reasons and it does not take a long time to read the files written to the mobile hard disk, so I personally Is not very likely to connect eSata interface, USB3.0 is more convenient. 2. Signal strength test From the perspective of signal coverage strength, the 2.4GHz band of the R7800 router can basically cover all the test points, and the network strength can also meet the daily use requirements (watch live streaming). The 5GHz band is limited by the characteristics of fast and fast transmission of high frequency transmission, resulting in a lot less performance than the 2.4GHz frequency band. Signals at points C and D, which have more obstacles between obstacles, are slightly weaker, but they can still guarantee the browsing of web video. Normal use. It should be noted that although the ASUS ac68u was released 3 years earlier than the NETGEAR R7800 Nighthawks X4S router, the mature firmware allows the ASUS ac68u to tap the maximum potential in the signal coverage, regardless of whether the 2.4GHz or 5GHz is slightly better than the NETGEAR R7800 night. One eagle X4S router, which also shows that the netparts R7800 still have potential to be developed. 3. Firmware review Since the R7800 is equipped with a Qualcomm processor, the firmware decompilation has not been able to proceed smoothly. The mainstream DD-WRT and Merlin firmware do not yet have the R7800 version. The existing niche LEDE and OP can be brushed and the LEDE is enhanced. The graphics performance but the native extension does not have much support, so this time still using native firmware evaluation. It takes about 1 and a half minutes to start NETGEAR for the first time. After entering the management page, it automatically prompts you to scan the Wan port and does not insert the broadband cable. Overview of the home page, shows the basic connection, the picture is monotonous, and the information is not enough, a large blank area on the right Although few setup options are available, the R7800 can enrich the 5GHz band by changing countries: Connecting hard disks requires ReayShare to select different access groups for startup. The setup is very simple. It is actually more intuitive and easier to understand than Merlin. The ReadyShare network disk appears on the network neighbor after it is turned on, and the various files on the U disk can be freely And Asus also need to download the Download Master in the external hard disk, netware directly integrated in the hardware download tool, although there is no mobile phone app (ASUS Download Master Client) can be downloaded remotely, but the actual download is good, BT resources Support is also very full The dynamic QoS of the NETGEAR is often promoted as a bright spot. In fact, the process of optimizing the experience is still performed by setting the network priority. However, this process will occupy a certain amount of CPU and will cause the USB transmission efficiency to drop. 194202ce.jpg" /> Finally, in the advanced settings, the default meshing R7800 is 100% power-on 2.5GHz, 5GHz, expansion options provide Beamforming, MU-MIMO, HT160 three options can be selected, the first two open helps the network wireless connection speed , The latter support is poor on some devices. The default shutdown event occurs. Fourth, summary advantage: Configuration is simple and intuitive; Strong and reliable performance; The default firmware is stable; Disadvantages: 80MHz+80MHz/160MHz bandwidth mode is not open in firmware; The firmware is simpler and the playability is not high; Insufficient integration with the mobile terminal and no remote download function; As a long-term torturing Meilin firmware person (ac68u, ac88u), NETGEAR R7800 gives people the feeling that food tasteless abandoned the pity, in the 1000 yuan in the high-end router provides a great hardware base, but the potential is because of the firmware Simple and can not be fully utilized, waste of such good hardware resources, in my open meshes R7800 Nighthawks X4 router is more suitable for small companies that need reliable and stable network, and do not like tossing home users, and high-end routing players in addition to In addition to the soft routing, you can consider buying RT-AC5300 in 618. The price around 1699 plus coupons can get a beautiful price, and it can really meet the needs of tossing for a long time in the future.
