Some websites unreachable - Network card at fault?
by BoraxMan from LinuxQuestions.org on (#6NZQ1)
I have two network cards in my desktop system, which runs Debian 12 (AMD 64)
They are...
Code:03:00.0 Ethernet controller: Qualcomm Atheros AR8121/AR8113/AR8114 Gigabit or Fast Ethernet (rev b0)
05:06.0 Ethernet controller: D-Link System Inc DGE-528T Gigabit Ethernet Adapter (rev 10)I had to take the D-Link out because I needed the PCI slot for another card. The Atheros is built into the motherboard. I can pull the network cable out of the Atheros and plug it into the D-Link, and the problems go away. The issue is I need to take the D-Link out because I need the slot for another card.
I noticed web browsing problems, and after some troubleshooting found that the problems only occur when using the Atheros adapter. If I use the Atheros adapater, I have trouble accessing some sites.
If I access https://askubuntu.com or https://superuser.com/ I get
Code:This site can't be reached
The connection was reset.but they work in firefox, but for Brave, Firefox and Palemoon, I may not be able to log into my banking. The point is, when I use the Atheros adapters, some websites fail to work. Note that I've tried the same sites under a different user account AND a new user account with a blank config, and the result is the same. I can ping these sites just fine, so its not a DNS issue. I seem to have no other network issues.
The computer is connected to a router via cable, auto assigned an IP.
So I'm quite confident, the problem is the Atheros adapter. MY question is, how can I troubleshoot? OBviously something is not right with it, but I'm not sure how to find WHAT that problem is.
The dmesg output which seems relevant to this card is
