Dear Community,
Some already have it, some will get it - the 2.5 Gbit Speed upgrade. On this page we inform you about some requirements for the speed rush. This thread is mainly dedicated to the hardware that must fulfill the requirements for 2.5 Gbit speed. In addition, non 2.5 Gbit capable devices can also benefit from the higher overall speed if several are used simultaneously.
Prerequisite for the hardware (modems), as well as the technology for fiber optics:
- Connect Box 3 HFC
- Connect Box 3 Fiber (only via XGS PON connection)
- Sunrise Internet Box Fiber (only via XGS PON connection)
- Internet Box Zyxel Fiber (only via XGS PON connection)
Explanation modem connection, only marked LAN connections have 2.5 Gbit
We have marked our compatible modems with the appropriate 2.5 Gbit connection in the first image of the thread. This means that the marked LAN connection must be used if you have one or more devices that require 2.5 Gbit.
Connection type 1: DIRECT CONNECTION
1.1 Your network card, which is installed in the laptop or computer, must provide at least 2.5 Gbit full duplex in order to achieve the speed in the network.
1.2 The network cable (LAN cable) must be at least Cat6 to achieve the 2.5 Gigabit speed.
1.3 Your hard disk should be able to write / read at least 300mb/s (=2.4 Gbit) so that the downloaded data can also be written to the hard disk at gigabit speed. As conventional HDDs are generally too slow, we recommend using an SSD to achieve the desired speed.
Connection type 2: via SWITCH
2.1 The LAN cable connected from the LAN 4 port of the modem to the switch should be at least Cat6.
2.2 The switch connected from the modem should be capable of 2.5 Gbit full duplex. When purchasing a switch, we also recommend that it can process the 2.5 Gbit per LAN port and not in total.
2.3 Your network card, which is installed in the laptop or computer, must be capable of at least 2.5 Gbit full duplex in order to achieve the speed in the network.
2.4 The network cable (LAN cable) must be at least Cat6 to achieve the 2.5 Gigabit speed.
2.5 Your hard disk should be able to write / read at least 300mb/s (=2.4 Gbit) so that the downloaded data can also be written to the hard disk at gigabit speed. As conventional HDDs are generally too slow, we recommend using an SSD to achieve the desired speed.
Connection type 3: via multimedia box / patch bay
3.1 The patch bay / multimedia box that is connected from the modem should be equipped with 2.5 Gbit full duplex LAN connections. If you are not sure what power the distribution box has to the corresponding network sockets, we recommend contacting the electrician who connected the multimedia box. The installer’s sticker is usually visible on the multimedia cabinet.
3.2 The network sockets that are connected from the multimedia box / patch bay must be designed for 2.5 Gbit or higher in the home. If you are not sure exactly what capacity the network sockets have, we recommend that you contact the installer.
3.3 Your network card, which is installed in the laptop or computer, must be capable of at least 2.5 Gbit full duplex in order to achieve the network speed.
3.4 All network cables (LAN cables) must be at least Cat6 to achieve the 2.5 Gigabit speed.
3.5 Your hard disk should be able to write / read at least 300mb/s (=2.4 Gbit) so that the downloaded data can also be written to the hard disk at gigabit speed. As conventional HDDs are generally too slow, we recommend using an SSD to achieve the desired speed.
Connection type 4: via own router / bridge mode
4.1 The LAN cable, which is connected from the LAN 4 port of the modem to the WAN port of your router, should be at least Cat6.
4.2 The router WAN connection must be capable of at least 2.5 Gbit.
4.3 Your network card, which is installed in the laptop or computer, must be capable of at least 2.5 Gbit full duplex to achieve the network speed.
4.4 All other LAN cables that connect other devices from your router should be Cat5e for 1 Gbit and at least Cat6 for 2.5 Gbit. In addition, your router, which also has LAN ports (normally LAN 1 - 4), must also provide Gbit.
4.5 Your hard disk should be able to write / read at least 300mb/s (=2.4 Gbit) so that the downloaded data can also be written to the hard disk at Gigabit. As conventional HDDs are generally too slow, we recommend using an SSD to achieve the desired speed.
Connection type 5: via WIFI
5.1 Due to technical limitations, speeds of 2.5 Gbit cannot be achieved via WLAN. The maximum speed that can be achieved is between 1.1 Gbit and 1.6 Gbit. In order to achieve these high transfer rates, the end devices in the WLAN must be compatible with the WIFI 6 standard.
Influences that can impair the speed:
Virus scanners
Virus scanners can affect the speed of the Internet as they check the downloaded data in real time. If the virus scanner can no longer follow, the data packets are placed in a queue and continuously rescanned, which can lead to a loss of speed.
Adapters / docking stations
LAN adapters, which are operated via a USB connection, for example, can reduce the speed as they are not designed for 2.5 Gbit speed or do not have full duplex - i.e. they do not support a guaranteed simultaneous speed (upload/download).
Firewalls (software or hardware)
Firewalls scan the network and, depending on the settings, all data packets. This can lead to the CPU of the hardware on which the firewall is operated (as in routers) offering insufficient performance and therefore the 2.5 Gbit speed cannot be achieved. We recommend checking the user manual or asking our community. If your router / firewall is running services that scan the network, we recommend deactivating these services, which may have the following names: AiProtection, Traffic Analyzer, Web History, Adaptive QoS, Game Boost, Web & Apps Filter, Bandwidth Monitoring, Mobile Game Mode.
Deactivating the services - one after the other and checking the performance in between - could reveal the cause that is throttling the speed.
