acer aspire one connection dropouts in jaunty
 
despite most people saying they no longer get connection dropouts in jaunty 9.04 i still do, especially when downloading anything! the file will appear to download okay but will be corrupt. This makes it impossible to use bbc iplayer since the player will get stuck after about 20minutes of use. It always relates to some "unsupported jumbo" message from the module which sounds incredibly helpful to the non module programmer :P

I have found many issues relating to this but they all appear to have been sorted in jaunty for those lucky people at least. No one has been able to give a straight reason as to why this happens though. would be nice if there was at least a work around.

look forward to hearing some suggestions

Jumbo is typically a term used to denote the size of an ethernet frame.
http://en.wikipedia.org/wiki/Jumbo_frame

Have you tried lowering the MTU in your network card or router ?



Did you see this bug report for jaunty ? https://bugs.launchpad.net/ubuntu/+s...ux/+bug/341952
and the proposed Update https://bugs.launchpad.net/ubuntu/+s...52/comments/62
Looks like it's still a work in progress, but there are definite issues with the ath5k Driver in Jaunty

one possible workaround was suggested in that thread to try the madwifi driver ath_pci, instead of the default ath5k.

To be completely honest and not at all linux "PC" I have found ndiswrapper to be the best wifi solution everything works including the lights.

ps if you want the widows drivers drop me a message and I will send as they can be quite hard to find

netsurf 06-11-2009 06:01 PM

yeah i installed backports and the driver is still naff. annoying how that didnt work. madwifi if memory serves was no good either for me. i'd love to try ndiswrapper if it would work until the ath5k issues are fixed.

farslayer 06-11-2009 10:06 PM

I run the Madwifi-openHAL driver for the wireless on my Acer Aspire One (AR5007/AR2425) and it works flawlessly..
It was the recommended driver from the madwifi-project team. ath5k Doesn't work at all for me in Debian Stable.

http://madwifi-project.org/ticket/1192

Lots of vulnerabilities popping up constantly with ndiswrapper, I'm not a fan at all..

Hi Farslayer,

Please explain wot vunerabilities, so far I have seen nothing but would be very interested if i should be aware of something.

farslayer 06-13-2009 11:08 PM

just do a search for "ndiswrapper vulnerability" in google.. there have been a lot that have popped up, been fixed, then a new one pops up, fixed.. repeat. then the recent round of emails with Linux over the status of ndiswrapper. Just too many isues for me to bother with. Part of the issue is that ndiswrapper runs as root, so if it's exploited, the attacker has gained root access.

If theres a native driver available I would never consider using ndiswrapper. call it a personal choice. I always check any wireless hardware before I purchase to ensure Linux compatibility and no need for ndiswrapper. that goes for any add in cards, or built in wireless as on Laptops, etc..

I've found that this bug is a result of poor hardware ASPM support.
It is a hardware bug that is worked around in windows driver by
disabling PCIE ASPM L0S.
There's a solution - turn ASPM L0S off for this device.

1. Download enable-aspm
kernel org/pub/linux/kernel/people/mcgrof/aspm/enable-aspm

2. Get your root complex:
$ lspci -tv
0000:00
...
+-1c.2-[0000:03]----00.0 Atheros Communications Inc. AR5001 Wireless Network Adapter
...

00:1c.2
3. Get your endpoint:
$ lspci
...
03:00.0 Ethernet controller: Atheros Communications Inc. AR5001 Wireless Network Adapter (rev 01)
...
= 03:00.0

4. Now you neet to edit your enable-aspm

# You just need to modify these three values:

ROOT_COMPLEX="00:1c.2"
ENDPOINT="03:00.0"

ASPM_SETTING=2

5. Now executing:
vo-one@acerone:~$ sudo bash enable-aspm
[sudo] password for vo-one:
Root complex:
00:1c.2 PCI bridge: Intel Corporation N10/ICH 7 Family PCI Express Port 3 (rev 02)
0x50 : 0x43 --> 0x42 ... [SUCCESS]]
L1 only

Endpoint:
03:00.0 Ethernet controller: Atheros Communications Inc. AR5001 Wireless Network Adapter (rev 01)
0x70 : 0x4B --> 0x4A ... [SUCCESS]]
L1 only

6. Making the script executed at system startup:
sudo chmod +x enable-aspm
sudo cp enable-aspm /usr/bin
sudo cat "enable-aspm" > /etc/rc.conf

hope that helps
