I recently bought an NSPIRE laptop from Novatech which came with a Realtek RTL8723AE Wireless Adapter. The drivers work fine in 13.10 but after about 10-20 minutes I lose connection to the internet. I am still connected to my router but not the internet.

It turns out that every device in the entire house that is connected to the network loses its internet when it happens to me on my laptop. The instant I disconnect from the network on my laptop or shut it down, all of the other devices regain their connection. If I disconnect and reconnect to the network I get my connection back for another 10-20 minutes until the process repeats again.

Here's the output of lspci | grep Net:

02:00.0 Network controller: Realtek Semiconductor Co., Ltd. RTL8723AE PCIe Wireless Network Adapter

And this is ifconfig wlan0 when the internet is working:

wlan0     Link encap:Ethernet  HWaddr 24:0a:64:dd:a5:f8  
      inet addr:192.168.0.104  Bcast:192.168.0.255  Mask:255.255.255.0

Now when it is not:

      inet addr:192.168.0.104  Bcast:192.168.0.255  Mask:255.255.255.0

      RX bytes:337183544 (337.1 MB)  TX bytes:15890324 (15.8 MB)

Here's iwconfig wlan0 when the internet is working:

Now when it is not:

      Mode:Managed  Frequency:2.437 GHz  Access Point: 64:70:02:C3:0A:C1

      Rx invalid nwid:0  Rx invalid crypt:0  Rx invalid frag:0

Any help would be really appreciated and I'd be happy to post any other necessary information.

Reboot your router? –  belacqua Feb 23 at 21:30
