Hi,
I just got an 100Mbit internet connection.
Running the test on:
http://www.speedmeter.de/speedtest/
I get 11Mbit/s vor my Linux and 97 Mbit/s with my Windows (same Laptop).
So what did I do wrong? I searched the forum for hints, but couldn't find the correct one.
what I did:
- used with/without netcfg
- used wpa_supplicant with nl80211 & wext (nl80211 gives me a higher bandwidth >100Mbit/s to the router. wext only the wireless-G 54Mbit. But thats not the problem)
- switched between brcmsmac & broadcom-wl
- installed pdnsd
- removed IPv6 module from loading

11 Mbit/sec is the speed of "full speed" USB. Would it be the problem? If your card is connected to USB, use for example lshw or lsusb -v to check that your card use USB 2 and not USB 1.

that can"t be the problem, because it is a notebook wireless card. It shouldn't be USB (i think all build in wifi-cards are pci), but I will check it.
Also my card wouldn't do 97Mbit on my windows, cause USB 2 only does 60Mbit. And I definitely don't have usb3.

no :-(.
as I said it is an normal pci card. Has anyone else some hints?

Difficult to say... Some things to try (but without warranty). By the way I have a notebook with an internal wifi card connected to USB (but I do not say it is your case).
1) Be sure that the problem is real: make several tests. Is it consistent.
2) Do a iwlist scan and check that you are not on the same channel as another computer in the same building (that can make interference). Try to configure the wifi with a channel not close to the channel used by another computer.
3) Make sure the problem is related to the wifi: connect the computer with a cable and remake the test.
4) Connect a second computer to the same router via a cable (to not interfere with the Wifi) and test the speed between the two computers (give them static address within the same network, start sshd and transfer a big random file between the two computers).
5) Try another distribution and see if the problem persists. If not retry in arch with the same kernel version of the other distribution.
6) Disable any encryption (WEP WPA) and remake the test. What is the output of iwconfig?
