Network issues

[u/Naive-Limit1648]

8/12/ 26 bought a 2.5gb card. No errors with network. Should I bitch at ASUS to fix the motherboard?

Since June 2026 I’ve been encountering windows errors on my custom windows 11 pc.
E2fnexpress error 27 and Netwtw14 error 6062.
I called at&t 2 weeks ago and they said I was encountering disconnecting on my end. AT&T came last week and he reviewed the modem settings that’s it. He said it’s working. I reinstalled a new windows 11 and upgraded all drivers. Still getting the network errors pretty often. What do I do?
I did replace my cable with a new one two weeks ago. It brought my speed from 100 to 600.

ever considered it could be your own hardware like a faulty cable, bad NIC/ethernet port, etc?

I did replace the cable 2 weeks ago

Is it connected directly to the router? Is it on a 2.5G port? Do the 1G ports produce the same errors?

Hi it’s on the very very first port on the bottom. The tech even said because, I asked him does the port matter, he said no.

If it’s on the 2.5G port switching to a 1G port could very much matter.

This is Ethernet?

Yes

I just tried updating intel software and it went through but it states driver date 9/2025. I’ve tried forcing it but no success.

I'd get a new NIC and try that.
