I am dual booting Windows 7 and Ubuntu 13.10 on a Toshiba Portege laptop, and for some reason I lose my wireless internet connection after about 15 minutes of use on Ubunutu after booting up. I am having no problems with Windows on the same network.
Here is the information on my wireless interface from lshw. Any ideas how I can fix this?
description: Wireless interface product: Centrino Wireless-N 2230 vendor: Intel Corporation physical id: 0 bus info: pci@0000:04:00.0 logical name: wlan0 version: c4 serial: 10:c3:c7:24:36:ba width: 64 bits clock: 33MHz capabilities: pm msi pciexpress bus_master cap_list ethernet physical wireless configuration: broadcast=yes driver=iwlwifi driverversion=3.11.0-26-generic firmware=184.108.40.206 ip=192.168.0.103 latency=0 link=yes multicast=yes wireless=IEEE 802.11bgn resources: irq:44 memory:e2400000-e2401fff
And ifconfig output immediately after disconnecting:
wlan0 IEEE 802.11bgn ESSID:"" Mode:Managed Frequency:2.452 GHz Access Point: Bit Rate=72.2 Mb/s Tx-Power=16 dBm Retry long limit:7 RTS thr:off Fragment thr:off Power Management:on Link Quality=70/70 Signal level=-29 dBm Rx invalid nwid:0 Rx invalid crypt:0 Rx invalid frag:0 Tx excessive retries:1 Invalid misc:65 Missed beacon:0
Not sure if this is relevant, but I am connecting to a D-Link router in Germany. I typically use this machine in the US. Network security is WPA/WPA2, IPvR is set to automatic and I set IPv6 to ignore.
