Hi, I'm new to arch so please bear with me if any of this is stupid.
I recently installed arch with no problems, but since some hours ago my network connection is not working correctly.
I am using network manager after uninstalling every other network service. It connects correctly but after less than a minute of browsing the web it stops working although it is shown as being connected.
When it stops working i cannot do ping to 8.8.8.8 or even to the router, but I can ping my pc's external ip address 192.168.0.22.
dmesg | wlp0s20u4 shows no errors, only authenticated and associated messages.
If I restart networkmanager it works again for a while.
After stopping networkmanager I reinstalled netctl just to check. Connected through wifi-menu with no problems. But the behaviour is the same, after less than a minute it stops working.
I have also noticed that if I am not browsing, only doing ping to google the connection keeps working for a long time.
This is not a problem of the router because I am correctly browsing with another pc.
Thanks in advance for your help

The weird thing about this is that the network will always stop working after I visit some pages. I can read the arch linux wiki or install pacman packages with no problem, but when I try to go to github the network will always break.
I know this sounds really weird, do you have any idea?

I found that when the network stops working the route command does not work, only prints the first line (Destination Gateway...) but then does not print anything else and I have to stop it with ctrl c
The output of arp -an is something like:
? (192.168.0.1) at <incomplete> on wlp0s20u9
and after restarting NetworkManager
? (192.168.0.1) at 20:e5:2a:d3:db:fb [ether] on wlp0s20u9
Thanks

What return "route -n" and "ifconfig -a" commands in both cases - when there is and isn't connection to the internet?

Is it just a matter of wireless or does this happen also when cable connected?
I have a wlan usb dongle with RTL8188CUS driver (use lsusb or lspci to identify your wlan adaptor). The corresponding kernel driver is not working. After a fresh install, wlan was working and always stopped after a very short while, just as you described.
Look at https://github.com/pvaret/rtl8192cu-fixes in case you have the same chipset and follow the instructions. They are for Debian/Ubuntu systems but work also on others. Just "linux-headers-generic" my have a different name on Arch Linux.

wtx: this is the information you requested, but i think it is the same on both

lokesh987: I haven't tried with the cable connected. My usb dongle is also a realtek, but RTL8187, which should be properly supported, as it works on another computer with ubuntu 14.04
Thank you both for your help
