Trouble connecting to open wifi networks in Arch Linux
Clash Royale CLAN TAG#URR8PPP
I have two open WiFi networks in my building, call them A and B. I have lived here for over two years and they have always worked, but now (after being away for a while) I've been experiencing problems that I can't diagnose.
The problem is that after a while (sometimes 5 min, sometimes an hour) the network I'm connected to stops and then I have to change to the other one. And this goes on indefinitely, where I have to keep changing between networks A and B.
I'm pretty sure this is a problem with my computer, because when I connect to the same networks with my phone they work perfectly. Also I have called the IT people here and they assured me that the network is working fine. The thing is, this doesn't happen with other networks (that I've noticed).
The problem is, I don't even know how to diagnose the problem, let alone fix it. I've tried resetting these connections and restarting the computer, I've installed all the updates (because maybe it's a bug on network manager introduced by an earlier update...).
How do I go about diagnosing this problem (and subsequently solving it)?
PS: I have Arch Linux (up-to-date) on a Samsung 9 laptop.
PS2: When issuing ping 8.8.8.8 I get normal results for a while and eventually it prints out:
From 000.00.000.00 icmp_seq=1311 Destination Host Unreachable
where the zeros above represent my current IP.
EDIT:
Pinging the router's IP gives me exactly the same thing as pinging 8.8.8.8: Destination Host Unreachable.
This is the output of Network Manager using journalctl --boot _SYSTEMD_UNIT=NetworkManager.service. Apparently the interesting line is the line with the warning and the message connection disconnected (reason 6). I have also caught a reason -3 there once or twice.
I've also tried this suggestion here but it didn't work.

I just checked the output of iwconfig when the connection is down and apparently the only thing that changed was the frequency from 5 to 2.4 GHz. However, I have issued the same command while the network was working and with the output being 2.4 GHz as well. So I don't think that is the reason.

That notebook model is known to have loads of wifi problems. You also do not specify neither brand of the wifi nor the model, however, it looks like a realtek which is a messed up chip. On top of all these circunstances, you also probably are bound to have wifi interferences, and probably the infra-structure is overloaded. I pretty much have honest doubts that dealing and debugging the sum of all those situations is on-topic here. tip: add to the question the output oflsusbandiwconfig.

@RuiFRibeiro I wasn't really aware of the problems of NP900. But this laptop has worked well since I've bought it almost 2 years ago. So it would be weird that a factory hardware problem is just acting up now out of the blue. I added the outputs that you asked pluslspciand I see no Realtek there anywhere. Any thoughts?

Please add also an iwconfig when associated/connected to an AP, or ideally two iwconfig with the two different APs
– Rui F Ribeiro
Jan 22 at 22:06
(adding iwconfig when in both APs might be useful to see the signal strength)

What happens if you use wpa_supplicant and dhcpcd instead?

EDIT 3
I just checked the output of iwconfig when the connection is down and apparently the only thing that changed was the frequency from 5 to 2.4 GHz. However, I have issued the same command while the network was working and with the output being 2.4 GHz as well. So I don't think that is the reason.

I have two open WiFi networks in my building, call them A and B. I have lived here for over two years and they have always worked, but now (after being away for a while) I've been experiencing problems that I can't diagnose.
The problem is that after a while (sometimes 5 min, sometimes an hour) the network I'm connected to stops and then I have to change to the other one. And this goes on indefinitely, where I have to keep changing between networks A and B.
I'm pretty sure this is a problem with my computer, because when I connect to the same networks with my phone they work perfectly. Also I have called the IT people here and they assured me that the network is working fine. The thing is, this doesn't happen with other networks (that I've noticed).
The problem is, I don't even know how to diagnose the problem, let alone fix it. I've tried resetting these connections and restarting the computer, I've installed all the updates (because maybe it's a bug on network manager introduced by an earlier update...).
How do I go about diagnosing this problem (and subsequently solving it)?
PS: I have Arch Linux (up-to-date) on a Samsung 9 laptop.
PS2: When issuing ping 8.8.8.8 I get normal results for a while and eventually it prints out:
From 000.00.000.00 icmp_seq=1311 Destination Host Unreachable
where the zeros above represent my current IP.
EDIT:
Pinging the router's IP gives me exactly the same thing as pinging 8.8.8.8: Destination Host Unreachable.
This is the output of Network Manager using journalctl --boot _SYSTEMD_UNIT=NetworkManager.service. Apparently the interesting line is the line with the warning and the message connection disconnected (reason 6). I have also caught a reason -3 there once or twice.
I've also tried this suggestion here but it didn't work.

That notebook model is known to have loads of wifi problems. You also do not specify neither brand of the wifi nor the model, however, it looks like a realtek which is a messed up chip. On top of all these circunstances, you also probably are bound to have wifi interferences, and probably the infra-structure is overloaded. I pretty much have honest doubts that dealing and debugging the sum of all those situations is on-topic here. tip: add to the question the output oflsusbandiwconfig.

@RuiFRibeiro I wasn't really aware of the problems of NP900. But this laptop has worked well since I've bought it almost 2 years ago. So it would be weird that a factory hardware problem is just acting up now out of the blue. I added the outputs that you asked pluslspciand I see no Realtek there anywhere. Any thoughts?

First thing I would look for are error-messages, in the kernel ring buffer, with dmesg. I would look for debug output of the WiFi hardware driver stack. I usually see Intel drivers reporting associated and dissociated events including reasons.
Destination Host Unreachable most often means there is no route to this destination. You can check routes with ip r. Also your ip addresses might be of interest: ip a. Manual pages for ip.
Get some more information and report back!

Thanks for the tips. Here's a pastebin of the output ofdmesg|grep -i wlp1. Pardon my ignorance, but is this the keyword I should be looking for? Looking forwlan0shows me nothing.

The keyword for yourgreplooks good and I can't find anything suspicious there. If you are using Network Manager you could look into its logs with this commandjournalctl --boot _SYSTEMD_UNIT=NetworkManager.service.

Also try to ping your router (inip rthe IP address after via) while your connection (ping to8.8.8.8) is not working.

Pinging the router just gives me exactly the same thing as pinging8.8.8.8:Destination Host Unreachable. This is the output of Network Manager. Apparently the interesting line is the line with the warning and the messageconnection disconnected (reason 6). I found this question with a similar error which I will investigate.

"reason 6: class2FrameFromNonAuthStation: Client attempted to transfer data before it was authenticated." (from wiki.ubuntuusers.de/WLAN/#Logbucheintraege-auswerten). From your log it looks like your where successfully authenticated and assosiated. Also you got reason 3 in your dmesg log, which states the access point is going offline. Maybe someone is running death attack in your neighborhood: en.wikipedia.org/wiki/Wi-Fi_deauthentication_attack . You could try to use the Wireshark packet sniffer to see if it's an deauth attack.

First thing I would look for are error-messages, in the kernel ring buffer, with dmesg. I would look for debug output of the WiFi hardware driver stack. I usually see Intel drivers reporting associated and dissociated events including reasons.
Destination Host Unreachable most often means there is no route to this destination. You can check routes with ip r. Also your ip addresses might be of interest: ip a. Manual pages for ip.
Get some more information and report back!

That notebook model is known to have loads of wifi problems. You also do not specify neither brand of the wifi nor the model, however, it looks like a realtek which is a messed up chip. On top of all these circunstances, you also probably are bound to have wifi interferences, and probably the infra-structure is overloaded. I pretty much have honest doubts that dealing and debugging the sum of all those situations is on-topic here. tip: add to the question the output of
lsusbandiwconfig.– Rui F Ribeiro
Jan 22 at 20:51
@RuiFRibeiro I wasn't really aware of the problems of NP900. But this laptop has worked well since I've bought it almost 2 years ago. So it would be weird that a factory hardware problem is just acting up now out of the blue. I added the outputs that you asked plus
lspciand I see no Realtek there anywhere. Any thoughts?– TomCho

Please add also an iwconfig when associated/connected to an AP, or ideally two iwconfig with the two different APs

(adding iwconfig when in both APs might be useful to see the signal strength)
