Could be hardware overheating perhaps.

the laptop loses the connection to my wifi. The speed goes down to 0 to 6 Mbit
What exactly happens when the connection is lost ?
Where are you measuring the speed ?
Do you mean the speeds drops from 6 to zero or drops to a value between 6 and zero ?
What do you have to do re-establish connection after it has failed ?

If the fault is reproducible, run some commands before it fails, then trigger the fault and run the same commands while in the failed state.
Check for differences in the two sets of results.

Hi,
Thank you for the reply and im sorry for the late reply, I missed the notification.
The issue are easily reproduced. I just need to start a file transfer from a smb share to another smb share via the laptop.
Its the laptop that reports the speed (the network widget). To re-establish the connection I need to disconnect from the wifi and then reconnect.
I managed the catch some errors in the journalctl, please see the attached snip.

Could be hardware overheating perhaps.

the laptop loses the connection to my wifi. The speed goes down to 0 to 6 Mbit
What exactly happens when the connection is lost ?
Where are you measuring the speed ?
Do you mean the speeds drops from 6 to zero or drops to a value between 6 and zero ?
What do you have to do re-establish connection after it has failed ?

If the fault is reproducible, run some commands before it fails, then trigger the fault and run the same commands while in the failed state.
Check for differences in the two sets of results.

As well as before and after for
Code: [Select]
lshw -C networkOther examples of commands to try include
Code: [Select]
sudo inxi -sni
Code: [Select]
ifconfig -a
Code: [Select]
route
Code: [Select]
arp -a
If you note the time when a failure happens, checking the logs around that time might show something.
Code: [Select]
journalctl --since HH:MMReplace the HH:MM for a value shortly before the fault.

Hi,

I have just starting using LL on my old Lenovo T400 laptop.
It connects fine to the AP and I'm able to surf and and stream media from smb shares. But when I do more heavier stuff eg FTP transferes the laptop loses the connection to my wifi. The speed goes down to 0 to 6 Mbit. I did find this in the logs.

journalctl -p 3 -xe
