    Re: slow wifi on Ubuntu 12.04

    If i type "alice.box" into my browser i get
    Code:
    Server not found
          
          
          
          
          
            
            
              Firefox can't find the server at www.alice.box.
            
    
            
            
    
      Check the address for typing errors such as
        ww.example.com instead of
        www.example.com
      If you are unable to load any pages, check your computer's network
        connection.
      If your computer or network is protected by a firewall or proxy, make sure
        that Firefox is permitted to access the Web.
    I have to look up the ip and type it in. There are worse things but it was easyer when i could just type the name.

    Re: slow wifi on Ubuntu 12.04

    I tried downloading a game with th ubuntu software center and it still feels kind of slow. I tried this to determin my speed more accuratly. dont know if its a good test for this purpose but i read it on some post.
    Code:
     ping -c3 8.8.8.8
    PING 8.8.8.8 (8.8.8.8) 56(84) bytes of data.
    64 bytes from 8.8.8.8: icmp_req=1 ttl=51 time=42.8 ms
    64 bytes from 8.8.8.8: icmp_req=2 ttl=51 time=43.1 ms
    64 bytes from 8.8.8.8: icmp_req=3 ttl=51 time=42.1 ms
    
    --- 8.8.8.8 ping statistics ---

    rtt min/avg/max/mdev = 42.180/42.716/43.127/0.396 ms

    Downloads with software center can be slow, I suggest type in internet speed test and try one of those to see what your actual speed is.

    Also how fast is your connection to begin with according to your isp?
    Thanks

    Re: slow wifi on Ubuntu 12.04

    Hey wild man,

    acording to my isp i have a 16000 conection. I did a speed test with the following page "http://www.wieistmeineip.de/speedtest/" yesterday runnig win7 and got a over 300000 kbit/s (download) which is kind of weird because its more than i pay for. Running Ubuntu its moro around 6000. I just repeated the test an have the following result: 5441 kbit/s download an 628 upload. Which the page itself rates as much to slow

    Re: slow wifi on Ubuntu 12.04

    Hi, sorry for the delay. I seem to be to much of a noob to do a screen shot. I tried out the samespeed test as you an have the following results. Download speed 5.25Mbps, Upload 0.60 Mbps and Ping 139 ms. I am sure that the 16000 stands for 16000 kbit/s or 16 Mbps.

    Re: slow wifi on Ubuntu 12.04

    Probably, that is not actually that bad for the speed you have from your isp.

    Does it load web pages a lot faster then before? I believe it does, you can remove the infotext file from your home folder and run the script again and post the new file and I will see what differences the changes made.
    Thanks
