[SOLVED] Pacstrap command kills internet connection

grim89 · 2015-12-20 22:01:16

I successfully installed Arch on my 7-year-old "side" laptop last weekend with no difficulty, and want to install Arch on my 3-year-old "main" laptop. Before running "pacstrap /mnt base base-devel" I ping google to confirm I have internet. Immediately attempting to run the pacstrap command, my internet gives out and I can't download any files. Internet returns once I physically disconnect and reconnect the ethernet wire (or returns on its own after ~30 minutes). I even tried using the same ethernet wire I used to install Arch on my side laptop.

Please help! Thanks in advance.

What's the exact name of the network controller that is used in this laptop? You'll probably see it in the "lspci" output. The kernel module for the device is seen in the output of "lspci -k". Try to search for problems about this particular controller. If other people report problems, there's probably parameters to use for the module to make it work well.

A long time ago, I had problems with a particular network adapter losing connection when transmitting large amounts of data. This reminds me of that.

Ethernet controller: Qualcomm Atheros AR8161 Gigabit Ethernet (rev 08)
Subsystem: Lenovo Device 3979
Kernel driver in use: alx
Kernel modules: alx

Do you see something interesting about alx in "journalctl -k"?

Check this out, scroll to the last post of the first page and try what's said there (all other posts have nothing that's said to be a solution, only the very last post on that page is interesting):

Here's the output:

# journalctl -k | grep alx
archiso kernel: alx 0000:02:00.0 eth0: Qualcomm Atheros AR816x/AR817x Ethernet [b8:88:e3...]

Also, I don't know what NIC up means in the last line, but as of right now, I don't have internet (unless I physically unplug and plug in the ethernet wire)

Wow, thanks for digging that up! Arch appears to be installing now, and I was THIS close to going back to Debian haha.

For the record, I did "ifconfig <interface name> mtu 9000", where interface name for me was enp2s0

Please mark the thread as solved. Also, if you intend to stick to Arch, you have to be much more patient and try to find solutions to problems yourself

Well, I did spend about 4+ hours trying to solve it, that's as far as my patience will take me before I have to return to being productive again. I wasn't expecting to encounter a hardware bug.

I love Arch's minimalism, so I'll definitely keep it on my side laptop, but I ran into issues with Grub on my main laptop (which is a dual boot with Windows), so I might be back with more questions or look for alternatives.
