With the i226-V development, it is not yet known whether it is a hardware or software error.
Intel announced it back in 2019 the arrival of the inexpensive 2.5 gigabit Ethernet adapterwhich was also launched in 2020 with the i225-V designation, but it became clear relatively quickly that in addition to certain 2.5 gigabit routers and switches it worked problematically. This could not be fixed in software, unless the limitation to 1 gigabit speed was considered as a solution, so Intel made a fixed version of the system.
The successor to this development is the i226-V adapter, which was released in 2022 and is also a design codenamed Foxville, and aims to provide cheap 2.5 gigabit Ethernet on individual products. In the meantime, however, it turned out that the new board, mainly with the 700 series control bridge, also has problems. The error phenomenon is that at intervals the system completely interrupts the network connection, which is restored after a few seconds. Many users are already complaining about this Intelthat is ASUS is in Microsoft forum, and the Reddit is.
It is not yet known whether it is a hardware or software error, but the phenomenon is independent of the connection performance, so it also occurs with a 1 gigabit network connection. Based on experience so far, it typically happens when the network load increases, and for some reason this is difficult for the i226-V adapter to handle, which disconnects the connection for a few seconds.
Since the cause of the error is unknown, it cannot be ruled out that it can be fixed by software, but for now Intel has not responded to the developments.
