Using Linux To Make a Slow, Awful WAN Connection

Julie188 writes "This is a brilliant little Linux trick from Windows fanboy Tyson Kopczynski. He wanted to test a new Windows 7 feature called Branch Cache, which caches remote data on the local machine to reduce traffic on a stressed out WAN connection. But how to fake a crappy WAN? Linux. 'The command that I executed (tc) made use of Linux Traffic Control (a kernel thing) which allows me to easily interject 100ms latency on eth1. Boff, Bonk, Pow, Plop, Kapow, swa-a-p, whamm, zzzzzwap, bam ... instant WAN crappiness,' he writes."

    *raises hand*

    Intel 8945J integrated wireless on my laptop. Dual boot, Zenwalk Linux and XP MCE 2005. Until the most recent driver from Intel, the wireless card was *significantly* stabler under Linux. It's now just as stable under Windows (though I replaced by router with a new D-Link 802.11n router recently too), but the throughput at long range is still better in Linux.

    As an example of the latter under Windows the useable range on my wlan caps out at about 25m. that's enough to cover my house, and much of the front lawn. Under Linux, I was able to connect to my network from the picnic table at the park across the street, about 100m. I was only getting 1mbit of throughput, probably less, but it was definitely getting better error correction and a more useable connection at that range than under Windows.

    I think the still haven't fixed the thing where Vista is limited to 100mbps if you are also playing audio.

    They should have stuck with the BSD network stack. As many bugs as they inserted into it to make it vulnerable, it still would pass traffic at the full data rate.
