sudo mv /lib/firmware/iwlwifi-7260-16.ucode  /lib/firmware/iwlwifi-7260-16.ucode.bak
Reboot and see if the version 13 firmware is better
So do I understand it correctly that I just need to make the newer versions "disappear" by renaming them and the system will - based on file naming - automatically figure out the latest version available and use that one?

I checked my old system and the last version on there is 13. For some reason, actually, versions 13's and 10's modification timestamps are just a few seconds apart...

So I will try out version 13 next time I reboot, I guess...

I have the Intel PRO/Wireless 3945ABG wifi card, so presumably that won't work for me.
There only appears to be one version (iwlwifi-3945-2.ucode) for that hardware.

Cheers,
Neil.

I switched back to version 13 because this was the last one I had been using in Mint 17.2, where I never had this problem.
Rebooted.

Unfortunately, the problem still persists even after that...

As a fallback, you can change wi-fi card to realtek or smth like that. :roll: Dell XPS has a little door from below...

I would power it down and cold boot to see if that helps. While it is powered off I would see if the wifi card is easy to access, remove it and then reinstall to see if it isn't a connection issue with the motherboard

Honestly, I don't feel like starting to mess with the hardware...

Last time it happened again, I checked the logs; this is from /var/log/syslog. Does this maybe give a hint?

Code: Select all

sudo iw reg set US
sudo sed -i 's/^REG.*=$/&US/' /etc/default/crda
This will set the country code and it might help to disable the firewall as UFW is known to block mDNS traffic

Does this have anything to do with the wireless connection dropping, though?

I think it might be relevant as I see this

And I have no other explanation for

Update: I switched to regular ethernet using a USB adapter since I could not figure this out.
That worked fine, until 1 or 2 weeks ago, I started having the same issue after waking up from suspend (refer to viewtopic.php?f=150&t=242604)
Not sure if the two issues are related....

I've tried Linux due to studies. Downloaded the iso in the official page and used unetbootin to extract the iso in my usb kingston. Installed Linux Mint 18.1 normally but got this wifi problems. I've read that network-manager had errors so I change it to wicd but the problem persists. I'll like some help too. I need this for university.

You would probably be better off starting your own thread on the problem you are having. The original poster probably doesn't have the same wifi device you have, and has now gone to use a wired connection. It's too easy to get your problem mixed up with the original posters. Start your own thread. Keeps the thread cleaner that way.
