[SOLVED] Acer Aspire One + Intel Wireless-N 1000 connection drops

0x000000 · 2011-11-23 05:01:37

Fresh Arch install, everything up-to-date (kernel 3.1.1-1 i686).

I'd originally been having crazy problems with my entire system hanging, but have since solved those with the iwlagn 11n_disable fix.

Now, the connection drops with no obvious pattern (it dropped about 24min after my last reboot and then another 27min after that as I am writing this). The only symptom I see is that Chromium gets stuck on "Sending request...". nm-applet provides me with no feedback and there's nothing out of the ordinary in dmesg. If I reconnect to the wireless network, everything's fine until it drops again. The last distro I used on this machine was Ubuntu 11.04 where this problem didn't occur, so that's the only frame of reference I really have.

Am I just looking in the wrong place for any errors? Much appreciated!

Do you have dhclient installed ? In the absence of specific configuration settings, Network manager will first try to use dhclient followed by dhcpcd. Arch defaults to installing dhcpcd.

On the networks I use, I find dhclient to be more cooperative than dhcpcd

For me drops have always been related to router issues or driver issues. I would guess driver from what you are describing. Is there any chance that this problem began when you updated your kernel? If so, try backdating the kernel and wait for the next update.

Yup, dhclient is installed.

Anything interesting in the output of dmesg related to the network ??

Edit: Nevermind, I re-read your post

I haven't updated my kernel since I installed Arch a few days ago (and of course did a pacman -Syu after installing), so it's hard to know. How would I go about backdating the kernel?

Downgraded the kernel to 3.0 (first 3.0 release) and ignored updates. I'll be sure to keep this updated once I can go a few hours without a dropped connection. Thanks!

if it works just put linux in the ignore pkg line of the /etc/pacman.conf file. Then you can run updates without worrying about the kernel changing.

Well, that seems to have worked (up almost 10h without incident). Like I said, I just went down to the first 3.0 kernel release (at least what was in ARM), so I can't pinpoint the exact release. Now, how do I mark this thread as solved?

Thanks dudes!

Just edit the title of the post.

I also had this problem with connection drops with the same wireless card, but on my Lenovo x121e. The issue seems to have magically resolved itself without me ever learning what went wrong. I think it may have went away when I upgraded Openwrt on my router but I'm not sure.

If you find out the source of the problem please share it.

Just kidding. Back at it again. On kernel 3.1.5-1 now. Definitely seems to be linked to the router: it's a lot worse on a Belkin F5D7230-4 using WPA than on my other WRT54GL with Tomato.

Not sure if this belongs here or not, but I'm also experiencing a full system freeze which I believe is related to iwlagn. I'll post the dmesg snippet once it happens again (something about queue stuck).

My problems seem to be solved by setting the iwlagn module option swcrypto=1. Disabling hardware encryption definitely sucks, but if it makes my laptop usable, I'm into it. I haven't noticed much of a difference, but it does seem like the fan is going a little harder now.

on my D255, i've recently found that blacklisting the atl1c module fixes the nasty freezes. of course, also coupled with the 11n_disable fix. found here: http://freeknowledge.wordpress.com/2011 … e-one-522/

solved? hope so.
