Hello. It's the first time I use Zorin OS 16.2 lite(and Linux, I was a windows user). I installed Zorin on my laptop(specifications: Dell Latitude E5410, I3 350M, 8Gb Ram) today, the design and system's speed are great. However, when I finished installing Zorin, the wifi led icon on my laptop began to blink every time, and my wifi connection speed became slow. I checked the logs and I found out those messages:
By the way, here's the wifi driver information:
Help me to solve this problem please, I really like that system
Gday @Gus Welcome to the community.
Are you running dual boot, or just Zorin OS?
Are you running both Ethernet & wifi at the same time?
Normally if the wifi blinks/flashes/question marked, can be caused by the remote wifi/router.
Try refreshing all modems/routers/computers involved within your network.
Most modern router/modems need approx 30sec to refresh, best to turn off, for 1 minute or so, to be sure.
The main thing is to let your ISP see your offline to refresh your line, if your using optic fibre this refreshing is done now while your connected.
Also disconnect Ethernet/service lines.
Also try here.
A sad bit here:
I would recommend trying
options iwlwifi 11n_disable=1
In termi8nal run:
sudo nano /etc/modprobe.d/iwlwifi.conf
options iwlwifi 11n_disable=1 to the end of the file.
ctrl+o to overwrite, then
enter to save current configuration. Tap
ctrl+x to exit the editor.
sudo modprobe -r iwlwifi
sudo modprobe iwlwifi
Hello Ocka. So, I'm running just Zorin Os, and I'm not running Ethernet and wifi at the same time, just wifi. Well, I tested my wifi connection speed on two devices, my cellphone and laptop(where I'm running Zorin) from the same distance and network, here's the result:
I don't know what happened, it was working fine when I was running windows.
Great Ping rate, it maybe a change of driver/firmware that is needed.
I would first check for BIOS firmware/driver updates.
In the link in my post above they seem to use an Intel driver ( seems modified to suit Linux).
First check BIOS updates!!!
Hello Aravisian. So, when I try to use sudo nano /etc/modprobe.d/iwlwifi.conf in terminal, this is what happens:
I don't know exactly what I should do here, when I try to append
options iwlwifi 11n_disable=1 to the end of the file, this goes to the beginning of the file:
It's my first time using linux, I'm still studying about this system, sorry if my questions are silly.
undo what you have done,
In the terminal you need to use your "Arrows" to move the cursor.
move down to the bottom the click "Enter" a couple of times, ( like in a txt file)
& add the command, then "Exit" & "Save".
Reboot after changes.
I still recommand you check for BIOS updates.
ADDED: just incase, to Exit the nano file, down the bottom says ^X this is.
Then next y to save changes.
I checked my current BIOS on CPU-X, and here's the information:
I searched for a BIOS update in Dell support site for my Latitude E5410, but it says that update is supported for Windows and DOS.
I'm not sure if I should update BIOS, my laptop is old and I'm afraid that my motherboard will malfunction or even stop working after an update, since this is a delicate process... By the way, when I changed the file you guys told me to edit, this improved the wifi connection speed a bit, but it's still slow. Maybe that ubuntu version doesn't work correctly in my wifi driver just like Aravisian mentioned above. Anyway, thanks for your help.
Yes updating the BIOS may help further, i see A15 2013 is the latest.
Here for direct link & checksum to help.
also here for Linux help,
you maybe lucky, it may have Internal BIOS update, within the BIOS , not all machines have this, the 2nd link will help if you need to flash the BIOS.
This shouldn't upset your machine ,
But as you know before any system alteration, you should run a backup.
As a side note, my laptop is slower than my phone,
22mb D/L 10 U/L
15-18 D/L 10 U/L
I use a 4G usb dongle as my internet connection as i live in a remote area,
My desktop speed is always slower than my phone with direct internet connection,
You may even check in BIOS in you have usb power boost, if so try that, this may happen by setting the performance power ( standard/quiet/performance/etc)
