Intel® Wireless-AC 9560

Post by steelerduk » Sun Mar 10, 2019 12:02 pm

Linux Mint 19.1 Xfce install with Intel® Wireless-AC 9560 WiFi download at less than 2mb/sec .... I've been reading here on many of the slow wifi threads and have tried many of the terminal commands with no improvement.

So I thought I'd see if someone here could walk me trough and see if I can get this WiFi running correctly . Please let me know what you need for me to post so we can get started trouble shooting. Thank you

FYI : newbie here as well to Linux.

iwconfig:

Code: Select all

wlo1      IEEE 802.11  ESSID:"Oort Cloud"  
          Mode:Managed  Frequency:5.785 GHz  Access Point: D4:AB:82:C8:C4:3B   
          Bit Rate=866.7 Mb/s   Tx-Power=22 dBm   
          Retry short limit:7   RTS thr:off   Fragment thr:off
          Power Management:off
          Link Quality=60/70  Signal level=-50 dBm  
          Rx invalid nwid:0  Rx invalid crypt:0  Rx invalid frag:0
          Tx excessive retries:0  Invalid misc:399   Missed beacon:0

lo        no wireless extensions.

lsmod | grep iwlwifi:

iwlwifi               299008  1 iwlmvm
cfg80211              667648  3 iwlmvm,iwlwifi,mac80211

echo "options iwlwifi 11n_disable=8" | sudo tee /etc/modprobe.d/iwlwifi11n.conf
           
options iwlwifi 11n_disable=8

Tried a few other tips from " SOLVED " slow wifi threads as well .... still slow download speeds. The upload speeds are correct however as far as upload speed on speed testing sites.

Thanks for any help.

Please generate an overview of your system like this:
- Launch a terminal window (this is how to launch a terminal window);
- make the terminal window full screen, to avoid chopped lines;
- Copy/paste this command into the terminal:

Code: Select all

inxi -Fxz
(if you type: the letter F is a capital letter)

Press Enter.

Copy/paste the output in your next message.

You might try this:

(item 7)

The driver you need appears to be this one:
https://wireless.wiki.kernel.org/_media ... 8819.0.tgz

Just follow the instructions in the how-to that I linked to, in order to install it.

Followed instructions ... I think it updated but not sure. Still very slow download speeds but upload speed is normal.

Thanks again Pjotr

TLDR Update the kernel to >=4.15.0-34. This can be done through the standard Update Manager.

I had the same issue, and was able to solve it by following the instructions here, namely by upgrading my kernel. You can notice in the changelogs for 4.15.0-50 that this issue with the 9560 is mentioned; namely that the 9560 is slow up until 4.15.0-20.

Just go through the Menu -> Administration -> Update Manager, and if it doesn't offer a kernel update by default, you can click View -> Linux Kernels to see available upgrades. I'd stick with 4.15.0-*, since these updates actually supersede what you have now and are Long Term Support, but from there you can just pick whatever's newest and suitably long-term-supported and follow the prompts to update.

After it's done installing everything, reboot your computer and verify your newly-fast internet at, e.g., speedof.me! I went from about 1-2 Mbps to just north of 75. Enjoy :)
