Identified Causes
4 causasPlaca de Rede (NIC) Defeituosa
75%O NIC no computador pode estar falhando ou apresentando problemas de hardware, levando à perda intermitente de conexão. Esta é uma forte possibilidade, considerando os passos de solução de problemas já tomados.
Problemas no Driver de Rede
60%Drivers de rede desatualizados, corrompidos ou incompatíveis podem causar instabilidade e quedas intermitentes de conexão, mesmo que o hardware em si esteja funcionando.
Configurações de Gerenciamento de Energia
40%Configurações agressivas de economia de energia na NIC podem, às vezes, fazer com que ela se desconecte ou fique sem resposta, levando a quedas intermitentes.
Conflitos de Sistema Operacional ou Software
30%Processos em segundo plano, software de segurança ou até mesmo falhas no sistema operacional podem interferir na conectividade de rede.
Recommended Solutions
8 soluçõesUpdate 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."
