I am somewhat new to Linux. Installed 64bit ubuntu 12.04 on a Dell XPS 13 i5core. This other thread deals with a related issue on 10.04, I'm nervous about following that advice for 12.04.
Machine has no problem connecting to my home wifi router, but the network connection freezes shortly afterwards for long periods. Rebooting the machine solves the problem temporarily only.
Based on other threads, this info should come handy:
Thank you in advance for your help.Code:sudo lshw -C network *-network description: Wireless interface product: Centrino Advanced-N 6230 vendor: Intel Corporation physical id: 0 bus info: pci@0000:02:00.0 logical name: wlan0 version: 34 serial: 88:53:2e:f0:90:74 width: 64 bits clock: 33MHz capabilities: pm msi pciexpress bus_master cap_list ethernet physical wireless configuration: broadcast=yes driver=iwlwifi driverversion=3.2.0-26-generic firmware=18.168.6.1 ip=192.168.15.129 latency=0 link=yes multicast=yes wireless=IEEE 802.11abgn resources: irq:47 memory:f0500000-f0501fff -------- sudo ifconfig -a lo Link encap:Local Loopback inet addr:127.0.0.1 Mask:255.0.0.0 inet6 addr: ::1/128 Scope:Host UP LOOPBACK RUNNING MTU:16436 Metric:1 RX packets:1094 errors:0 dropped:0 overruns:0 frame:0 TX packets:1094 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:139966 (139.9 KB) TX bytes:139966 (139.9 KB) wlan0 Link encap:Ethernet HWaddr 88:53:2e:f0:90:74 inet addr:192.168.15.129 Bcast:192.168.15.255 Mask:255.255.255.0 inet6 addr: fe80::8a53:2eff:fef0:9074/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:23085 errors:0 dropped:0 overruns:0 frame:0 TX packets:15443 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:27144683 (27.1 MB) TX bytes:1902828 (1.9 MB) --------- lo no wireless extensions. wlan0 IEEE 802.11abgn ESSID:"AXTEL-f360" Mode:Managed Frequency:2.437 GHz Access Point: 5C:D9:98:FD:F3:60 Bit Rate=135 Mb/s Tx-Power=15 dBm Retry long limit:7 RTS thr:off Fragment thr:off Encryption key:off Power Management:on Link Quality=57/70 Signal level=-53 dBm Rx invalid nwid:0 Rx invalid crypt:0 Rx invalid frag:0 Tx excessive retries:50 Invalid misc:582 Missed beacon:0 ---------- wlan0 Scan completed : Cell 01 - Address: 5C:D9:98:FD:F3:60 Channel:6 Frequency:2.437 GHz (Channel 6) Quality=57/70 Signal level=-53 dBm Encryption key:on ESSID:"AXTEL-f360" Bit Rates:1 Mb/s; 2 Mb/s; 5.5 Mb/s; 11 Mb/s; 9 Mb/s 18 Mb/s; 36 Mb/s; 54 Mb/s Bit Rates:6 Mb/s; 12 Mb/s; 24 Mb/s; 48 Mb/s Mode:Master Extra:tsf=00000018b790415e Extra: Last beacon: 136ms ago IE: Unknown: 000A415854454C2D66333630 IE: Unknown: 010882848B961224486C IE: Unknown: 030106 IE: Unknown: 2A0100 IE: Unknown: 32040C183060 IE: Unknown: 2D1AEE1117FF000000010000000000000000000000000C0000000000 IE: Unknown: 3D1606050700000000000000000000000000000000000000 IE: Unknown: 3E0100 IE: Unknown: DD180050F2020101800003A4000027A4000042435E0062322F00 IE: Unknown: 7F0101 IE: Unknown: DD07000C4307000000 IE: Unknown: 0706555320010B10 IE: Unknown: DD1E00904C33EE1117FF000000010000000000000000000000000C0000000000 IE: Unknown: DD1A00904C3406050700000000000000000000000000000000000000 -----------
