I'm getting several type of problems with most obvious the low speed and low signal. More rarely I'm getting disconnections or the wifi-manager keeps asking for the wireless key (although I'm entering the right one). Also after suspending there are no networks on network-manager and all selections are grayed out.

Also, in dmesg I have a lot of:
brcmf_cfg80211_reg_notifier: not a ISO3166 code (0x30 0x30)
and
brcmf_inetaddr_changed: fail to get arp ip table err:-23

Some info about my wireless:

sudo lshw -class network

(returned nothing)

Thank you in advance.

  • Please edit your question to add the results of: sudo iw reg get and also: sudo dpkg -s bcmwl-kernel-source – chili555 Mar 18 '17 at 13:35
  • @chili555 When I ran the second command it told me that the package is not installed and when I installed it I lost networking. Now network-manager says "No network devices available". How can I revert back without internet? (My laptop doesn't have a lan port.) – Yannis Mar 20 '17 at 10:00
  • @chili555 Ok, I was able to "purge" it and return in the previous status. – Yannis Mar 20 '17 at 10:52
  • The point of the command was to be certain that the incorrect driver was NOT installed and interfering; not to install it. Let's also see: dmesg | grep brcm and also: lsmod | grep -e b43 -e ssb – chili555 Mar 20 '17 at 12:38

After spending a lot of time researching how to solve my problem, I realized that the best solution was to change my wireless card with an Intel one.
This way not only I solved my wireless network problems but also my Bluetooth problems.

I know this answer was not what I was expecting, but if I knew it I would have spent the 20$ and 2 minutes to change it a long time ago.

So my advice to anyone that have problems with the wifi of Dell XPS 9550 is to change the wifi card (I used this one: Intel Wireless Dual Band AC 8260NGW 867Mbps WIFI Card Bluetooth 4.2 8265NGW).

I would like also to thank @chili555 for his time.

  • Thanks for your answer! I'll see if I can get a wifi card replacement on my country. How do you know if it's compatible? (hardware here is kind of expensive) – morhook May 22 '19 at 20:26

    @morhook You can find the one I used for under 15$ in eBay or you can check the cards these laptops use: certification.ubuntu.com/desktop/models/… – Yannis Jun 1 '19 at 11:42
  • Looks like I might travel to United States finally. I'll buy on eBay a new card!!! Thanks @yannis for your comment. – morhook Aug 2 '19 at 3:58
