The 700series motherboard used in Intel 12gam13 CPU is defective, characterized by random network outages.

Thanks to CTOnews.com net friend South China Wu Yanzu, Xiao Zhan cut the clue delivery! CTOnews.com January 22, TechPowerUp reports that some of the I226-V Ethernet LAN controllers for Intel's 700 series motherboards for 12th and 13th generation CPUs have failed. Feedback from some Intel, Microsoft, ASUS and some Reddit community users shows that it mainly manifests as random network disconnection problems.

Intel hasn't made an official statement about the issue, but it's not a new issue for the company, as the previous generation Ethernet LAN controller I225-V had similar flaws, such as network connectivity outages and performance losses.

Intel later released the I225-V2 to alleviate the problem with the previous version, but it was a hardware issue after all, so there would still be a lot of users affected, and for those who did not want to buy an updated motherboard, they could only reduce the LAN port speed to 1GbE.

Reported that the current I226-V drop situation does not last long, but when playing games, downloading large files and conducting conference calls will be more obvious, users can "Windows Event Viewer" in "Windows Log" in "System."

CTOnews.com Reminder: You can also verify whether it is affected by searching for "e2fnexpress" event 27 or event 32.

Of course, some high-end 700 series motherboards come with dual Ethernet controllers, and users are free to choose third-party controllers from Realtek and Marvell, or switch to Wi-Fi on the motherboard.
