Ethernet card Qualcomm Atheros AR8132

Installing and Using OpenWrt
1

Hello,

Today, I installed 32bits version of OpenWRT 19.07 on an old Medion E1221 laptop,
By default, no ethernet card is recognized.

lspci reports the ethernet card as:

Qualcomm Atheros AR8132 Fast Ethernet (rev c0)
Subsystem: Pegatron device 00aa

Which package should I add so the ethernet card can be used ?

If # lspci -vv yields the PCI ID you can just google that with together with 'Linux' driver, then you'll find the name of the Linux driver. Which you can then match to the kmods available here. My money is on one of the kmod-atl* packages.

Should be kmod-atl2. The atl1 driver is for gigabit chips and atl2 for 10/100 "Fast Ethernet" chips.

Thank you very much for your reply, and solution.

The package which worked is:
kmod-atl1c_4.14.162-1_i386_pentium4.ipk

Here's the result of "lspci -vv"

I'm still wondering where is this "PCI ID" I should google...

Thank you again...

lspci -knn should display it, without -nn the numerical IDs are often omitted or replaced with their textual equivalent (e.g. "Pegatron"), which makes it hard to search for.

Here's the result of 'lspci -knn'

01:00.0 Ethernet controller [0200]: Qualcomm Atheros AR8132 Fast Ethernet [1969:1062] (rev c0)
        Subsystem: Pegatron Device [1b0a:00aa]
        Kernel driver in use: atl1c

So the PCI ID would be 1b0a:00aa ?

No, that would be the subsystem ID, the PCI ID to look for would be 1969:1062.

From a general purpose linux distribution: 
$ grep 1969.*1062 /lib/modules/$(uname -r)/modules.alias
alias pci:v00001969d00001062sv*sd*bc*sc*i* atl1c
