r8169: Link is down

Just moved to another place and I can't get my internet to work, and it has been a couple of days of me trying to debug this but to no avail. Wifi has not been working either and at the moment I am trying with a cabled connection but I cannot connect. `dmesg` shows the folloing:

[1101242.981240] RTL8208 Fast Ethernet r8169-0-200:00: attached PHY driver (mii_bus:phy_addr=r8169-0-200:00, irq=MAC)

[1101243.265040] r8169 0000:02:00.0 enp2s0: Link is Down

some of the times it just shows:

[1105137.989660] RTL8208 Fast Ethernet r8169-0-200:00: attached PHY driver (mii_bus:phy_addr=r8169-0-200:00, irq=MAC)
[1105138.250037] r8169 0000:02:00.0 enp2s0: Link is Down

What I have tried:

  • `sudo modprobe -r r8169 && sudo modprobe r8169`

  • `sudo ethtool -s enp2s0 speed 100 duplex full autoneg off`

  • `ip link set enp2s0 down && ip link set enp2s0 up`

  • tweaking router networking settings turning on and off stuff, disabling filters, etc.

  • didn't manage to get anything on `tcpdump` (at first there were some packets sent that I did
    not catch but which were registered on the router history but after that the connection was cut,
    tried to repeat those packages by moving to another interface on the router, but the same thing happened)

Mentioning that:

  • I cannot ping the router

  • laptop wifi and ethernet work just fine at work

  • another 2 phones and a laptop can connect just fine to the network (had some problems with one of the phones too but it works now)

  • (sorry but I might be slow to respond to requests since I am not permanently moved to
    the place and might take up to a week to give new logs if I am not there sad )

  • also had this question on reddit https://www.reddit.com/r/archlinux/comm … k_is_down/ but moving the question in the forum

Re: r8169: Link is down

I don't see an obvious root cause in your journal. Here are some observations that could be relevant:

1) Your kernel dates from back in October; when was the last time you ran pacman -Syu?
2) You have installed the relevant linux-firmware, correct?
3) There appears to be a lot of network configuration mentioned in your journal, how exactly have you configured your network(s)? These entries, for example, seem bizarre:

Nov 23 22:06:59 rabbit dnsmasq[652]: bad address at /etc/hosts line 31
Nov 23 22:06:59 rabbit dnsmasq[632]: read /etc/hosts - 97176 names

You really have almost 100,000 entries in your /etc/hosts file?

Re: r8169: Link is down

I ran the last `pacman -Syu` back in october, I don't do the updates as often as one should unfortunately, I ran it after I've seen the problems on the wireless connection, tried to do the updates to maybe fix them but to no avail. I don't know what other linux-firmware I could be installing; the wireless and cabled connection are working usually, it is just this new router that is behaving.
My /etc/hosts has a lot of entries most of them copied from a github project that enumerated some ad websites that are often used; I have it so I block some extra ads or entries on shady sites etc. (this is also outdated probably sad )
Can the problem be router related?

Re: r8169: Link is down

`pcie_aspm` is not toggle able in the kernel options, it was on bios default (which I don't know what it was) and I specifically made it to be `performance` which as I understand it should be off. But it didn't help, I'll put some logs from the wifi connection, there seems to still be a power limiting (should I try manually hitting `no` for the `pcie_aspm` in the kernel config and build it ?)

dmesg logs:

(secrets were provided it just fails with that message, but it is not relevant, tried using the `ask` option to ask for the password but after entering it a few times it still fails)

Re: r8169: Link is down

This has nothing to do with the BIOS, did you click the link on how to add kernel parameters?

Also r8169 isn't a wifi chip and you're getting kicked by the wifi AP, the reason might bethat it doesn't like MAC spoofing, https://wiki.archlinux.org/title/Networ … domization
But that has absolutely nothing to do with the subject of this thread.

Re: r8169: Link is down

Good news, after running another set of `pacman -Syyu`, restarting, and doing the `echo performance > /sys/module/pcie_aspm/parameters/policy`, the wired connection is working at last; (the wifi is still not working but at least I have internet); Do you think I should try more to remove the `pcie_aspm` from the kernel in order to figure the wifi out?

Re: r8169: Link is down

Yes, I've clicked on the link, it had different methods of adding parameters to how things are handled; I've found the `pcie_aspm` and tried to remove it by doing `make menuconfig` and create a config that way for the kernel, but I wasn't able to

Re: r8169: Link is down

I doubt the wifi issues (which are just introduced into this thread off topic) are related to aspm? Or did/does the connection work w/o aspm control?
Did you try to disable the MAC randomization?

Re: r8169: Link is down

update again, internet worked for like half an hour, now is no longer connecting on anything again. Starting to feel like its a router problem, once I was connected the internet started to fail on other devices (phones, another laptop)

router: `fiberhome SR1041Y`

edit: wifi was never working, mentioned this in the first post on this thread, mac randomization is off

Re: r8169: Link is down

Are you currently talking about the r8169 connection or the wifi?
Journal for that situation? (paraphrasing "does nots works" is devoid of any meaningful information)

once I was connected the internet started to fail on other devices (phones, another laptop)

You mean once the r8169 connection was established your phone and other laptop got kicked from the router?

Did you try to reboot the router?
Is it running out of leases (because of stale ones)?
Do you implement a MAC filter on the router?

Re: r8169: Link is down

to answer some of the questions:

+ once the connection was established the other devices were not automatically kicked out, rather there were periods where the router seemed to no longer be processing packets, causing noticeable waits of seconds up to several minutes
+ Yes I rebooted the router multiple times
+ I don't think it is running out of leases (i reserved my interfaces to have static ips)
+ there is no mac filtering

I'll come back with logs for the wireless interface also (once i get to get them)

Re: r8169: Link is down

Also check "ip -s l" on whether you've many transmission errors.
And try a different cable.

Re: r8169: Link is down

Didn't manage to get another connection in to see dropped packages (at least with the current cable -- I don't necessary suspect the cable since it is a new one, I've also tested it with a cable tester, but didn't plug it in other networks to check for sure; I will test with another cable when I get the opportunity).

Also got some logs on the wifi failing (might offer more feedback - it looks more verbose at least compared to the wired connection):

The wifi AP simply doesn't like your password?

Re: r8169: Link is down

I've tried resetting the connection and remaking it several times, in the end it worked connecting. What I usually see is I run nmcli connect with the `-a` flag to ask for the password, I enter the password, it asks for it again, and this repeats like 5 times then it fails or times out (usually if the password is incorrect the connection will fail on the first try, so it seemed like the handshake failed / was reset multiple times before failing).

At the moment I'm trying to replicate the failing again, because I don't know what changed; not ruling out the fact that the connection will work only temporarily again

Re: r8169: Link is down

Ftr. the wired connection on over r8169 doesn't work at all?
And "it is just this new router that is behaving"?
Firmware update? Does the router keep logs?

Re: r8169: Link is down

for the wired connection I've seen 3 states it can be in; the router either straight up blocks the connection, or makes the connection then it seems there are some packages that are dropped coming from me by the router itself kicking me out afterwards, or I get connected for a short while then if other devices enter the network I might get kicked out (?); and yes it is only this router that seems to be behaving like this;

I'll try looking for some firmware updates;
I don't think the router keeps any logs, at first sight the only thing I saw was a log of the number of packets received then dropped (that's how I know in some cases I get connected for a very short while);
When I get disconnected after the first few packets, I can no longer reconnect even if I switch the interface where I connect to. (I've looked through the settings, there weren't any macs getting blocked, no firewall present, I somehow get shadow blocked? getting the wire in and out of the laptop doesn't do anything, I don't know what is happening there for the router to no longer receive any packets, instead of receiving then dropping; I don't remember if resetting the interface worked or I had to wait a certain amount of time - I'll be checking this aswell)

I don't think we've seen any journal for that condition? (Only for the wifi-failures) have we?

Unfortunately that router model doesn't seem very well (publically) documented, the only manual I could find was "plug the cables into the slots" - thanks for the absolute pro-tip roll
