Wlan



  • its not coding related, but since there are some sysadmins lurking around, perhaps someone can help

    i had a 3 mbit internet connection and my setup was: adsl modem -> wireless router -> computers ... worked nicely ...

    since the local providers are at each others throats, i was offered a nice deal where i pay less and get more (up to 20 Mbit as the prospect promised), so i canceled 3 MBit, ordered new one and there my problems began... i got 11 Mbit (that is what the DSL line supports) and wanted to enjoy the goodnes of high speed downloading porn linux distributions ...

    however it turns out that i cant get more than 3 Mbit over WLAN ... when i connect the computer and the adsl modem with the network cable, i get 8-10 Mbit download ...

    i got another router box from the isp, an all-in-one adsl modem, wlan router with 11g (54 Mbps) support so the setup is now ads modem + wlan router -> computers

    what i tried so far :

    - switched channells on the router

    - switched to 11g (g only, not combined)

    - switched to 11g++

    - reduced to 11b

    - updated firmware on router

    - updated drivers for the adapter 

    - changed wlan adapters on the computer

    - used another computer

    - used another wlan router (so the setup was adsl modem (works as a modem) -> another wlan router -> computer)

    - brought the bloody computer to the bloody router so their antennae are in cm distance from each other

     

    every time the computer connects, computer and router both indicate full bandwith and excellent quality of the signal ... the connection never drops and never reduces the bandwith ...

    both computer run XP SP 3, no firewalls ... oh, yes and i tried disabling QoS packet scheduler and deterministic network enhancer, so the network adapter now has only tcpip protocol ...

    record was 3,6 MBit ...

    help ...

     

     



  • Obviously Windows XP detects that you are trying to download Linux distros, and throttles the download speed in an anti-competitive shady move. You should try downloading porn and see if the problem sustains. Post results, please.

    That won't always increase the signal through-put. In fact it can actually worsen it.



    As for the question on hand, are you sure you're not reaching the maximum upload from the source? Are you sure they (the source) isn't throttling their upstream? Have you tried a speed-test?

    tried streaming "Wild Asses V" in full HD ... the experiment produced jerkiness ... im definitely going to try this one again ... a bit later ...

    I am using 2 different speedtests (the internet provider and speedtest.net)... with WLAN i get 200-250 kBps,disconnect WLAN, connect LAN Cable and rerun the same test, 1100-1200 kBps, disconect cable, connect WLAN, rerun the test, 200-250 kBps ...



    however, I found a workaround ... the router runs under linux, it has wget and i got a simple ftp client (a simple bt client is available as well) ... it has an usb host as well ... so i just telnet over, tell him to download stuff to the usb hdd ...

    i'll write a small shell script to read a certain text file on the drive and parse the links, and perhaps send some notification when its done (ring the phone or something) ...

    Maybe install a real proxy?



  • Have you tried changing the WLAN channel? 2.4GHz is an unlicensed band, so anything from cordless phones to baby monitors to other WLANs in the area could be causing interference and reducing your speed.

    Nevermind, helps if i read the OP thoroughly

    yeah, but the proxy would go again over WLAN, so I'm limited to 2-3Mbit, which is the thing i'm trying to avoid ...



  •  My experience with wireless is: It's just slower. Unless you're in a lab with a faraday cage and ideal-everything, the "connection speed" it reports has nothing to do with "the amount of data you can send per second". I got one of the "N" wireless setups, windows reports 300 +/- Mb/sec in the connection properties, but what I actually get for data rate between two machines on either end of the wireless connection is more like 40 Mb/sec. It's just barely enough to stream high quality video/porn, with the occasional stutter, which becomes a lot of stuttering if you're doing anything else over the network. This happens whether or not I'm in the same room as the router or downstairs through a few walls. I've played with channels, firmware, settings, etc, etc just like you have and that's the best I can get out of it. 

    My fiancee's laptop doesn't use 802.11n, and she gets about 8 Mb/sec of actual throughput.

    This is also my experience on networks other than my home one.  Trying it out just now at work, I get 12 Mb/sec on the corporate wireless, and our IT here tends to know what they're doing.

    Porn is completely worthless without the occasional stutter.  Speech impediments turn me on.
