X61s Slow Downloads- 4965AGN Wireless, Fedora Core 10

[Harryc]

I have an X61s that I just installed Fedora Core 10 on, Dual booting with Vista Home Premium. I have a 3MB Down, 768KB Up DSL service. Test results below using speakeasy, including all the machines in this room. Why is the Fedora download speed so slow? In fact the X61s Vista results are on the same machine/wireless adapter.

Fedora 10 uses the brand new iwlagn driver instead of the older iwlwifi (iwl4965) one. If you want to track down this issue you should try iwlwifi instead.

2854/751 - Opensuse 11.1.
I de-installed Fedora. Thanks for the reply.

Just to add to this, I had to compile the latest compat-wireless binary in OpenSUSE 11.1 because I was still experiencing dropouts on wireless. It's working 100% now. See the below links;

I had a slow down issue in Mandriva KDE4.
I installed Suse 11.1 Gnome and it seems to working fine.
I installed this on my R61 which I use as my Linux Lappy.
And as far as I can tell everything works. Including wireless out of the box except for configuring.
I have been running it for about a week now. Without any problems.

Is this related to the kernel? The bug report read like it was.
Or is it a KDE4 issue?

Doog, I think it's an issue with the new driver for Intel iwlagn. Even after I did the update mentioned above, I am still having drop-out problems on wireless. I may just fall back to a distro with the iwlwifi driver until things get worked out. OpenSUSE 11.0 comes to mind ... On the other hand, they seem to be making changes to iwlagn almost daily, so I may give it another few days worth of upgrading to the latest version.

That´s why it´s called iwlagn

Just wondering are you running 32bit or 64bit.

Maybe try these links.
Have you read this post on Suse forums? "I'm sure you have"

2nd is for 11.0 but you maybe will have to revert back to that.

Doog, thanks for the links. I'll have a look at them. I want to try the compat-wireless dujour first to see if anything has improved.

Ok, I have Opensuse 11.1 running flawlessly now on wireless. I had to do (2) things. First I pulled the Intel 4956agn card and installed an Atheros (Thinkpad) agn card. I was still getting occasional wireless drop outs. Then I disabled knetworkmanager and used the traditional IF-Up method in YAST. It's been running 24 hours now without a hick-up.

Thanks for the update
I thought I would mention for other users that you need to disable IPV6 .
Usually that is just a given

Just to add another data point, here is Fedora 10 kernel-2.6.28.1-19.fc10.i686 and using iwlagn from the Fedora kernel:
