Identified Causes
4 原因ネットワークインターフェイスカード（NIC）の故障
75%コンピューターのNICが故障しているか、ハードウェアの問題を抱えている可能性があり、断続的な接続損失を引き起こしています。これまでに実施されたトラブルシューティングの手順を考慮すると、これは可能性が高いです。
ネットワークドライバーの問題
60%古い、破損した、または互換性のないネットワークドライバーは、ハードウェア自体が機能していても、不安定さや断続的な接続切れを引き起こす可能性があります。
電源管理設定
40%NIC のアグレッシブな省電力設定は、NIC が切断されたり応答しなくなったりする原因となることがあり、断続的な切断につながります。
オペレーティングシステムまたはソフトウェアの競合
30%バックグラウンドプロセス、セキュリティソフトウェア、あるいはオペレーティングシステムの不具合がネットワーク接続を妨げる可能性があります。
Recommended Solutions
8 ソリューションUpdate NIC Drivers
🤖 AI Analysis
"The problem is intermittent wired internet drops, and updating NIC drivers is a common and effective solution for such issues, especially since the problem started recently. This directly addresses potential software conflicts or bugs within the network interface card's driver."
Clean Install NIC Drivers
🤖 AI Analysis
"A clean install of NIC drivers can resolve issues that a standard update might not, especially if there are corrupted driver files. Given the recent onset of the problem, a fresh driver installation is a strong candidate for resolution."
Disable NIC Power Saving
🤖 AI Analysis
"Power saving features in NICs can sometimes cause intermittent connectivity issues, especially if they are too aggressive. Disabling these features is a straightforward troubleshooting step that can resolve unexpected drops."
Test with a USB Ethernet Adapter
🤖 AI Analysis
"Testing with a USB Ethernet adapter is a good way to isolate whether the issue lies with the onboard NIC itself or its drivers. If the connection is stable with the USB adapter, it strongly suggests a problem with the onboard NIC or its software."
Rollback NIC Driver
🤖 AI Analysis
"Although the user hasn't explicitly mentioned a recent driver update, the problem started 'recently.' If a driver update did occur automatically or was overlooked, rolling back to a previous stable version could resolve the issue."
Perform a Clean Boot
🤖 AI Analysis
"A clean boot helps identify if a background application or service is interfering with the network connection. While less direct than NIC-specific solutions, software conflicts can manifest as intermittent drops."
Temporarily Disable Firewall/Antivirus
🤖 AI Analysis
"Firewall or antivirus software can sometimes interfere with network traffic, leading to intermittent drops. Temporarily disabling them is a valid troubleshooting step, though less likely to be the primary cause for a wired connection issue compared to driver or hardware problems."
Replace the NIC
🤖 AI Analysis
"Replacing the NIC is a more drastic step and should be considered only after other software-related solutions have been exhausted. It's a possibility if the onboard NIC is physically failing, but less likely than driver issues given the recent onset."
