Olá pessoal, desculpa se eu estou postando esse tópico na categoria errada ou se estou provendo informações demais ou o contrário. Estou no Arch porém esse problema eu já tive antes no windows e acabei até trocando o modem, o que acontece é que minha conexão fica dropando e volta continuamente, muito rápido quase imperceptível, nas chamadas no skype é coisa de apenas a voz dos outros falhar um segundo e voltar, nem cair a chamada cai, outros programas que precisam de conexão avisam que ela caiu, mas também não afeta muito o desempenho e rapido ele ja avisa que voltou...

Depois de localizar o driver com o
lspci -v 
esse foi o retorno:

07:00.0 Ethernet controller: Realtek Semiconductor Co., Ltd. RTL8111/8168/8411 PCI Express Gigabit Ethernet Controller (rev 15)
Subsystem: ASUSTeK Computer Inc. Device 8677
Flags: bus master, fast devsel, latency 0, IRQ 38, IOMMU group 12
I/O ports at f000 [size=256]
Memory at f6504000 (64-bit, non-prefetchable) [size=4K]
Memory at f6500000 (64-bit, non-prefetchable) [size=16K]
Capabilities: <access denied>
Kernel driver in use: r8169
Kernel modules: r8169


e após isso rodei
dmesg | grep r8169 
para ver se tinha carregado o driver da NIC e esse foi o retorno estranho...

campeão ... se vc está tendo problemas no Linux e ja teve o mesmo problema no windows o problema com toda certeza não é nos SO's, geralmente quando a conexão banda larga fica caindo é problema no cabeamento ou no modem ... como vc disse que já trocou o modem é uma de verificar o cabeamento ( não esqueça de testar com outro filtro de linha ).

Segundo o log q vc enviou o link de dados é que está caindo. Possibilisades:
1- cabo de rede defeituoso (mais provável)
2-porta ethernet do switch c problema(mal contato)
3-porta ethernet do computador c problema
Faça testes p descartar os priblemas anteriores.

1- cabos de rede gostam de se partirem por dentro depois de algum tempo. Seria intencional?
2- de vez em quando é necessário puxar os "aramezinhos" da porta ethernet do switch de volta para o lugar, usando um "clips" em forma de "L" (e mão leve, é claro).
Eles se deformam com o tempo (e com o peso do cabo) ocasionando mal contato.
