Intermittently dead ethernet ports

Can you try another cable?

I can swap out one from another device…I’ll give it a try. I have been using this cable for a few years now for connections to various other routers, and it’s always worked perfectly, but I suppose that something may have broken/worn out…I’ll try later and report back. Thanks for the reply, SQBI.

OK, I finally got around to trying a different cable - no luck, the connection still intermittently dropped.

After a bit of head-scratching, I disabled my anti-virus software (Avast), and that has resolved my issue. I’m trying Windows Defender for a while as a replacement - so far, the connection seems to be fine.

Good to know. You could report your issue to the Avast’s tech support.

I may try to verify it by reinstalling first, but good idea - thanks.

the issue where the ethernet ports don’t come up at boot with certain devices was fixed in the kernel included with the recently released 3.5.2. I used to have that issue but don’t anymore post that update.
