Hi,
Is there a way to find out whats the maximum bandwidth available
both in wired and wifi connections available on my laptop running
Ubuntu Desktop 11.10.
01:00.0 Network controller: Atheros Communications Inc. AR9285
Wireless Network Adapter (PCI-Express) (rev 01)
03:00.0 Ethernet controller: Realtek Semiconductor Co., Ltd.
RTL8111/8168B PCI Express Gigabit Ethernet controller (rev 06)
Laptop Make/Model :- Dell Vostro 3450
See iperf/netperf, which available from repo.
Also is there a way to know if my wifi card is confirming to
802.11g or 802.11n standards.
$ iwconfig
lo no wireless extensions.
eth0 no wireless extensions.
wlan0 IEEE 802.11bgn ESSID:off/any
Mode:Managed Access Point: Not-Associated
Tx-Power=19 dBm
Retry long limit:7 RTS thr:off Fragment thr:off
Power Management:off
My wifi card supports b/g/n standards (IEEE 802.11bgn)
For more information about net to witch you connected (or want to
connect) run:
sudo iwlist wlan0 scan
On my system if I run 'sudo iwconfig' I get the connection speed
too:
wlan0 IEEE 802.11bgn ESSID:"xxxxx"
Mode:Managed Frequency:2.462 GHz Access Point:
14:D6:4D:AE:12:A2
Bit Rate=86.7 Mb/s Tx-Power=19 dBm
Retry long limit:7 RTS thr:off Fragment thr:off
Encryption key:off
Power Management:off
Link Quality=35/70 Signal level=-75 dBm
Rx invalid nwid:0 Rx invalid crypt:0 Rx invalid
frag:0
Tx excessive retries:4 Invalid misc:1010 Missed
beacon:0
It still shows "802.11bgn", so I don't know if you can really see
which Wifi standard the network is using.
