Frequently Asked Questions
Will this 5Gb network card work in a PCIe x1 slot?
Yes. YuanLey lists support for PCIe x1, x4, x8 and x16 slots, so you can use a short x1 slot and keep the larger slots free for a GPU or storage cards.
Can I use it with my current gigabit router or switch?
Yes. The RTL8126 chipset negotiates 5G, 2.5G, 1G or 100Mbps automatically, so it connects to gigabit gear. Your link speed matches the slowest device in the path, so you need a 5GbE-capable switch or router to get full 5Gbps.
Will it fit in a small form factor or low-profile case?
Yes. The card comes with both a full-height bracket and a low-profile bracket, so you can install it in a standard tower, a compact low-profile case or a rackmount chassis.
Which operating systems does the YuanLey RTL8126 adapter support?
The manufacturer lists Windows 7, 8 and 10, Windows Server, Linux and VMware ESXi. Windows 11 and macOS are not named, so check the product listing or the Realtek driver page before buying for those systems.
Does this network card support Wake-on-LAN?
Yes. Wake-on-LAN is supported, so you can power the PC on remotely for off-site backups or remote maintenance. You may also need to enable WoL in your motherboard BIOS and in the OS network adapter settings.
