Where to buy

AXAGON PCEE-G25 PCI-Express network card adds high speed 2.5 Gigabit Ethernet connection to your desktop computer. Backward compatible with Gigabit and 10/100Base-T networks.

The network card is equipped with Realtek RTL8125B chipset. It ensures seamless compatibility with most operating systems. The LAN adapter supports network boot (PXE) and also Realtek Dragon Software for settings management and automatic bandwidth control.

2.5G Ethernet network card expands the computer with a very fast network connection, adds the missing RJ-45 connector, add another network card or replaces the original defunct network connection. The advantage of the IEEE 802.3bz standard is that common Cat 5e and Cat 6 Ethernet cables up to 100 m long can be used for speed of 2.5 Gb/s.

In addition to an adapter with a standard size bracket, the package also includes a low profile bracket which allows the mounting into low profile cases.

A): If the PC does not run with the card or the card is mistakenly detected in “Device Manager”, or if there is a yellow exclamation mark on the driver, or if “Device Manager” reports an error code “Code 10 - The device cannot start”, the card is in conflict with another device in your computer.

B): In most cases, this conflict can be solved by moving the card to another PCI (PCIe) slot, with the BIOS assigning other free resources to the card. If the move does not help, try the card separately, with no additional cards inserted. If the card cannot be moved to another slot, you can reset the BIOS of the computer (by jumper on the board or pulling out the backup battery, we recommend that you note all the original settings and reset everything to the required values). This will cause the IRQ, DMA, and I/O resources to be redistributed.

A): If the network card is not displayed in "Device Manager", a USB port (or a PCIe slot in the event of an internal network card) may be malfunctioning.

B): Try plugging the network card into another USB port (or another PCIe slot on the PC motherboard in the event of an internal network card, or temporarily disconnect all other PCIe cards). The network card should be detected and you should be prompted to install the drivers. If the problem persists, plug the network card into the USB port (PCIe slot) of another computer to verify its functionality.

A): If this happens, it means that the operating system failed to get the necessary information to install the drivers.

B): The cause may be a defective USB extension cable or damaged device. If the problem persists, plug the network card into the PCIe slot of another computer to verify its functionality.
