Networking suddenly stopped
« on: December 21, 2018, 08:41:39 pm »
Hi all,

I have been running peppermint for a few years now with almost no issues on an old Asus Netbook. It seems that due to some upgrades, the networking (wired and wi-fi)  is working no more. I have also noted that since jumping from version 7, firefox or chromium are extremely slow to load and keeps working slow no matter what. It gets worse if trying to watch any youtube videos.  I barely use this netbook but need to get it working for a project so I will appreciate any help you can provide me with.
Network hardware for wired  is Qualcomm Atheros AR8132 Fast Ethernet with driver :atl1c
Wi-Fi  has a Atheros AR9285 wireless network adapter with driver: ath9k

Thanks in advance for your help

Have you tried booting into the previous kernel and seeing if networking works ?

Sorry, I was unable to reply from my laptop. For some reason the reply button does not show up so I'm doing it from my phone.
I tried from oldest kernel but stays the same. It detects my two networks, but says there's no internet when trying to open a web page. I checked the connection info and see that the speed sits at 1Mb/s.

So network manager says you're connected to your router, but you cannot access the internet ?

Can you ping your router and get a response ?
ping -c 5 <ip.address.of.router>
eg.
Code: [Select]
ping -c 5 192.168.0.1
if so, can you ping Google and get a response ?
Code: [Select]
ping -c 5 216.58.204.78
?

do you see "yes" anywhere if you run:
Code: [Select]
rfkill list
?

and if you run
Code: [Select]
nmcli connection show
is anything in green text ?

Are any of those lines in GREEN text ?

And what's the output from
Code: [Select]
iwconfig
and
Code: [Select]
iwlist scan
you may have to copy this output to a text file, then copy the text file to a working computer to post it here.

And just out of curiosity, I take it you've already tried restarting your router ?

Router is working fine, have 2 laptops and 3 phones upstairs connected to the same router.  Reset router again but no change at all. Keeps saying that there's no internet when trying to open any website.

Have you tried restarting the router ? .. give it a shot anyway.

If that doesn't makew any difference, let's try get a handle on the wireless chipset .. can you post the output from:
Code: [Select]
lsusb
if it's a USB wireless adapter.

and/or:
Code: [Select]
lspci -vnn | grep -i net
if it's an internal adapter

This thread got me thinking... I haven't started my EeePC in awhile. Turns out, the last time I booted it was 22 Apr 2017, according to the logs.

Good ol' girl. I literally had to dust her off. Then, plugged in the battery, a P9R 32bit ISO thumb drive, hit the 'on' button, danced on the 'Esc' button, and she sprang to file - WiFi and all. Hadn't even plugged the charger in yet - wanted to see if would happen without it    ;D
 
Don't know if this will help, but here's the dialog I'm getting on my WORKING EeePC 1000HD:

Try this, and tell me if you get any errors:
Code: [Select]
sudo rmmod ath9k
then
Code: [Select]
sudo modprobe ath9k nohwcrypt=1
did wireless come back to life ? .. and is it connecting faster than 1Mb now ?

If it didn't come back to life (or threw an error on the rmmod command), reboot (which will get you back to where you are now), and we'll have to try it another way.

If it works, let me know and we'll make that permanent.

Just tried it and the wi-fi shows a connection speed of 120 Mb/s but as soon as I try to open a webpage, drops to 1Mb/s and stays the same :o

Okay let's test temporarily making it permanent and rebooting. (good grief I just used "temporarily" and "permanent" in the same sentence ???)

Anyway, run:
Code: [Select]
gksudo xed /etc/modprobe.d/ath9k.conf
when a BLANK file opens, add this line to it
Code: [Select]
options ath9k nohwcrypt=1
SAVE the file and close the text editor.

Now REBOOT.

How is wifi now ?

If it's still having problems, can you answer this question .. does your laptop have bluetooth as well as wireless ?
