I installed Antergos a couple of days ago and the whole experience so far has been really good. My thanks to the developers and to the users of this forum.
However, I have run into an issue with my WiFi connection. In short, I am able to connect to my router, but my connection is either extremely slow (11-1 Mb/s) or I don’t have internet at all. The strangest thing is, that during the installation my wireless connection was working flawlessly.
So in more detail (I apologize for the long post) — I am dual-booting Windows 10 Creators and Antergos on the same hard drive on a Dell Inspiron 15R 5521 laptop. My laptop uses the Intel Centrino Wireless-N 2230 adapter.
lspci -k confirmed that the adapter is recognized and it is running the correct driver: iwlwifi version 18.104.22.168. Continuing on with
ip link, which confirmed that the interface was created and was set up (wlp8s0 in my case). And
iw dev wlp8s0 link showed that I was indeed connected to my router. I have also received a static IP address, as seen by
ifconfig. Everything seems fine with my netmask. Everything seems fine in the
ip route as well. The problem isn’t in the DNS either(I have tried manually setting the server to 22.214.171.124).
iwconfig I find an abysmal bit rate of 11mb/s, which according to the gnome network manager is even 1mb/s. Pining google.com results in
ping: www.google.com: Name or service not known, pinging 126.96.36.199 results in
4 packets transmitted, 0 received, 100% packet loss, time 3031ms and finally pinging my local gateway results in the same:
4 packets transmitted, 0 received, 100% packet loss, time 3040ms. It is interesting to note the output of
dmesg | grep -i error:

So it appears that the problem is from iwlwifi. I have found that people have had similar problems with different Inter adapters. The solution for them was downgrading the kernel version, which I still haven’t tried. I find it strange that the driver would have problem, when I can connect to the router. Furthermore, I don’t understand how everything worked during the live usb session.
In summary, I have spent the last 2 days fighting with this problem and I now feel somehow lost. I do not understand enough about networking to be able to solve this myself. I would be really grateful for any help or suggestions with this issue.
Thank you in advance.
