Another way to increase the range is a stronger antenna. Unfortunately, the connection of external antennas is not possible with every WLAN device – so pay attention to it when you buy it. If the connection is still too low after upgrading, you can use a WLAN repeater (repeater). These devices read the traffic and resend the packets with a correspondingly higher range.
The test
WLAN repeaters do not require any additional connections apart from the power supply. The repeater from AVM is even slightly larger than a socket. However, repeaters have a disadvantage: since WLAN is a shared medium and a repeater re-transmits each transmitted packet, the effective bandwidth in the entire network decreases. The installation of a Repeate will be used for the repeater to be detected by the WLAN. Here you take the network SSID.
For the access point variant, the device must be brought into the repeater mode. Subsequently, the type of encryption must also be defined here. Best to buy a repeater that supports WPA2. If the repeater also offers WPS, the encryption can be done at the touch of a button.
All of our devices have a built-in four-port switch, a WAN port, and a DHCP server, which allows you to provide all address information to clients on the LAN. Apart from the router from SMC, the controllers are also equipped with MiMo antennas. This antenna system uses reflections to increase the range.
AVM equips the 7390 radio with a gigabit switch, instead of 100 Mbps, as is common in the competition. In the field of safety, all test candidates offer the equipment that corresponds to the current state of affairs. This includes a stateful packet inspection firewall to secure data transfer between LAN and WAN and port forwarding to provide internal services to the outside.
Even a DMZ host, which is interesting when a small LAN wants to provide a server with its entire functionality on the Internet, all routers offer in the test. Of course, the WLAN encryption is not missing and so master all tested models WPA2, WPA and WEP. In addition, a feature for blocking URLs is included with all routers except AVM and Belkin.
With SMC, Belkin, D-Link, Zyxel, Edimax and Linksys, a complete content filter is added. Content / URL filtering is a very important consideration for all who have children. The two routers in the test, which have this feature, are very comprehensive in content / URL filtering and provide many ways to set up network access child-friendly.
For example, specific keywords can be entered, which block individual websites or entire domains. The controllers of AVM and Linksys also offer a scheduler in which it is possible to set up individual settings, on which days and times access to the Internet is blocked or allowed. In this way, parents can surf on Internet sites that are locked up for the offspring.
Unique feature: Unlike the competition, the FritzBoxen bring a USB port. The 7390 even has two such connectors. You can connect printer, mass storage or a UMTS-Stick. If you connect an external hard disk or a USB stick, you can integrate this into the network. The NAS functionality is extensive, but also very slow.
When reading, it creates barely more than 3.7 MB / s and writing 4.1 MB / s. The streaming of films works in most cases, however, in the case of HD material occasional short jerks. There are real problems, however, only when several HD movies simultaneously. Just as no internet traffic is more then on the box possible and it is during the streaming hardly reach the webbrowser.
The processor load moves according to the built-in energy monitor at the upper limit. Very nice: The Fritz box 7390 is equipped with a VDSL modem, a DECT base station for cordless telephoning and a telephone system.
