A major problem with my wireless connection

[BlueDaisy]

Oh my, I similtaniously posted with you, snowhog.

Here's how it goes: my family uses Earthlink as the internet provider. When they signed up, this router I spoke of was given to them, as well as instructions to configure it. They followed all instructions, and all was well. All my family used windows or a mac, and it was I who introduced linux to the household. Apparently, at the start, I complained about the problem, but they reluctantly pushed me away, saying "the problem isn't the internet connection - It's perfectly fine" and they also refused to see the router configuration, scared that I might blow it up, or anger the internet provider. No trust at all... Windows/Mac, plus the router just works for them (although I'm slowly understanding their troubles with windows)

Like I said, using fedora bypasses the problem - but it's not good in other areas, such as its weak repository, problems with using NVIDIA drivers, and other things. In this way, it made me think my problem occurs elsewhere.

I'm going to start by limiting my download speed. Is this part of the thread exactly how to do it, or do I need to do large substitutions into the code?

Re: how to limit apt-get download speed
I found a better sollution.
create file /etc/apt/apt.conf.d/76download with content:

Acquire
{
Queue-mode "access";
http
{
Dl-Limit "25";
};
};

That limits apt-get to 25KB/s

Teunis,

You hit the problem exactly when you showed me the program "wondershaper." I downloaded it, and used this command:

sudo wondershaper wlan0 2400 300

I configured software sources to the main server, and then everything worked perfectly, limiting to 300 kilobytes a second - regular downloads, apt, flash (somewhat) and software repositories. I didn't need to mess with apt files either.

Apparently, my internet connection was "lying" to my computer - it said it was connected at 54 megabits a second, when in reality, downloads max out at 2.5 megabits a second. When it tried to go higher, it must have annoyed the router to really slow the download speeds. I just hope this configuration stays, even if my computer restarts.

Thank you so much! Now I might try 12.04 alpha one...

Glad you got it sorted out BlueDaisy Congratulations for sticking with it.

Well, as far as your computer knows the internet is your wifi connection which is theoretically 54Mb/s. The problem isn't that it should have known that the rest of the internet might be slower (here in SA we can run over a 4Mb/s ADSL line but still hit worse congestion on the international submarine cables) - the problem is how the TCP/IP sessions handle reports of congestion - which is basically the receive window size thing I mentioned earlier. There's probably still some kind of bug, exposed in your particular configuration but not in general for *buntu, but wondershaper is effectively preventing you from hitting that bug.

Glad it's fixed!
