    [SOLVED] Slow wireless on Slack 12.2 and broadcom driver


    i have installed the broadcom driver from their site /very slowly and with a couple of broblems, but it works/. The connection is extremely slow, like 10kbs.
    BUT when i download from torrent i get like 2-4 MB/s. Browsing and ping gets very slow.

    I f i run ping yahoo.com i get:
    Code:
    PING yahoo.com (206.190.60.37) 56(84) bytes of data.
    64 bytes from w2.rc.vip.re4.yahoo.com (206.190.60.37): icmp_seq=1 ttl=0 time=129 ms
    64 bytes from w2.rc.vip.re4.yahoo.com (206.190.60.37): icmp_seq=2 ttl=0 time=132 ms
    64 bytes from w2.rc.vip.re4.yahoo.com (206.190.60.37): icmp_seq=3 ttl=0 time=128 ms
    64 bytes from w2.rc.vip.re4.yahoo.com (206.190.60.37): icmp_seq=4 ttl=0 time=128 ms
    64 bytes from w2.rc.vip.re4.yahoo.com (206.190.60.37): icmp_seq=5 ttl=0 time=129 ms
    but it takes 7-8 seconds before the first ping appears, and 3-4 sec for every other ping.

    Running Slackware 12.2 kernel 2.6.29
    iwconfig eth1
    Code:

    It's like every time i try to connect to a page it reconnects to the wireless router...
    i'm using wicd 1.5.6

    Under XP there are no problems

    any help is appreciated

    This wouldn't affect the download speed, but slow DNS resolution can happen if you have the ipv6 protocol enabled. Try blacklisting ipv6.

    I don't know slackware too well, but usually there is a file at /etc/modprobe.d/blacklist or something along those lines. If it isn't there, you can also create your own file in /etc/modprobe.d. The contents of the file should read blacklist ipv6

    Sometimes that alone doesn't do the trick, in which case you can add a line install ipv6 /bin/true

    i did blcklist and it didnt help, so i added install ipv6 /bin/true to the blacklist file, and now i think there is slight inprovement but still very slow. Now it opens the pages somtimes very fast and most of the time still very slow.

    nslookup looks up the other DNS server, so i put it in first place. That seem to speed up the connection. I'll test it a couple of days to see if it's ok.

    EDIT: Everything is normal now. I just wonder why slackware prefers to use the second DNS server.
