What is I211?
The Intel® Ethernet Controller I211-AT contains two transmit and two receive queues for the single port. These queues, combined with Receive Side Scaling (RSS) and Message Signal Interrupt Extension (MSI-X) support, provide a toolset for optimizing the performance on multi-core processor designs.
What is Intel I211-at?
The Intel® Ethernet Controller I211-AT pro- vides an ideal GbE solution for customers looking for a full-featured Gigabit Ethernet Media Access Control (MAC) and Physical- Layer (PHY) solution. The Intel® Ethernet Controller I211-AT uses a PCIe v2. 1 one lane (x1) interface operating at 2.5 GT/s.
Why do motherboards have 2 Ethernet ports?
Motherboards with two LAN ports are used if you want to assemble a small network (e.g. share your internet connection, files and printer with another computer) without buying a router — so your computer will work as a router.
What is the difference between Realtek and Intel WIFI?
Intel NICs will generally give, at minimum 5% greater throughput than a Realtek. Under extreme circumstances the difference can be much greater. The difference is greater on large transfers than on small transfers. If you want your NIC to saturate its link as much as possible, go with Intel.
Can I connect two Ethernet cables to my PC?
Since most computers do not have multiple Ethernet ports, you will have to use a USB-to-Ethernet adapter to connect your second Ethernet connection. Make sure this second Ethernet cable comes from a different router device than the first one.
Should I use both Ethernet ports on my PC?
to keep it simple, your two network ports are for the use of connecting to two networks at the same time. there is no purpose to them for 99.9% of home users.
What is Realtek NIC?
Realtek Ethernet Drivers are the software driver that facilitates communication between the Windows PC operating systems and Realtek Ethernet cards. Having the Realtek Ethernet Driver is required for the hardware to function correctly. The most common version of this driver in use today is 10.1.
Is WiFi 5 enough?
Ideally, you should use the 2.4GHz band to connect devices for low bandwidth activities like browsing the Internet. On the other hand, 5GHz is the best suited for high-bandwidth devices or activities like gaming and streaming HDTV.
Why do servers have 2 Ethernet ports?
Increased Efficiency with Multiple Ethernet Ports Each additional port allows a computer or server to move more data through for increased throughput. Separate networks connected to a single server allow the one network to continue functioning when the other is experiencing maintenance downtime.
Which is better Intel i210 or i219?
Interestingly, the I210 supports up to four RSS queues and may result in better performance at very high load. Jumbo Frames up to 9KB on I219 and up to 9.5kB on the I211. Low power features on the I219 claims to consume less then 1 mW with Ethernet cable disconnected (perfect for not using it).
Which is better the IGB or the i211?
The I211 with the igb driver is the clear winner. It worked out of the box on Arch Linux on kernel 4.9.6. The hardware supports a few more minor bells and whistles to improve performance while lowering CPU load and the support from the kernel driver leverage these features.
What are features of Intel Ethernet controller i211?
Intel® Ethernet Controller I211 I211 controllers support speeds up to 1GbE on a single MDI port with advanced features such as 802.3az Energy Efficient Ethernet (EEE), 802.1AS precision timestamping, ECC Packet Buffers and Integrated Non-Volatile Memory.
How does the i210 work with the i350?
As I understand, the i350 works very well with VMs. Essentially, with the i210, each VM will either need a NIC allocated to it to be efficient, or the hypervisor’s VirtualSwitch will have to do the work. With the i350, the NIC can act as many virtual NICs, so each VM can have one, and thus the work of the “Virtual Switch” is offloaded to the NIC.
