I am using Manjaro KDE with the 4.14.34-1-MANJARO kernel. I also have Windows 10 dual booted.
When I connect to my the internet via WiFi, I get speeds like 4kBps with ocassional timeouts in speedtest.net.
Heres the info of lshw:

bus info: pci@0000:03:00.0
logical name: wlp3s0

resources: irq:131 memory:b4000000-b4001fff
As you can see I have the firmware v29. So the fw is updated.
When I switch back to windows I get my full speed (1 mBps) so windows is unaffected.
I tried running another distro (Ubuntu 17.10) from a LiveUSB and there too the speeds are tremendously slow.
Now if I connect my phone to the same wifi, and use USB thethering to connect my laptop to the internet, the speed is what I expect (1mBps) which I think confirms that it is probably the linux driver thats having trouble.
My laptop is the Acer Aspire A515-51G having the 8th gen Intel i5.
I have also tried switching to another router and the speed is still slow. (~4kBps)
It's really frustrating to have to usb thether my phone every time I use the internet so I can even browse smoothly.
please tell me how can I go about solving this.. because on windows I have NO problems whatsoever. It's only linux distros causing issues.
Edit: Even pinging to my router is unrealisticly slow

Okay so I ran this:
echo "options iwlwifi 11n_disable=1" | sudo tee /etc/modprobe.d/iwlwifi.conf
sudo modprobe -rfv iwlmvm
sudo modprobe -rfv iwlwifi
sudo modprobe -v iwlwifi

This seems to have fixed it but I don't think this is the "Ideal" solution.
Thanks for posting and sharing the workaround for this issue.
