LinkSys WRT54GX2 - What the status and what to do

Postby Dwaine » Fri Jan 18, 2008 2:10 am

I have read that this router has problems. I'm wondering what the status is, and what I can do to get the XO to connect to it.

I have tried and I get the router to completely lose network connectivity when the XO tries to connect to it. All equipment attached to the router loses network connectivity too. When I shutdown the XO, network connectivity is restored.

Need a tester?

[olpc-help] LinkSys WRT54GX2 - What the status and what to d

This is a known bug, for routers using Airgo's first generation MIMO radios:

We are attempting to put together a comprehensive list of these routers

Is it a bug in the chipset or could it be possibly be fixed with a firmware fix?

Maybe we could follow up with tech support with these vendors; getting them to take a look at the problem.

The current software does not support the MIMO.

It would be nice to see this solved. My public library just happens to
be running their public WiFi access through this same model of router.
My XO is not welcome at the library :-( since firing it up, shuts down
access to all users of the public WiFi there...

Boy does the router not like the xo laptop... It completely shuts down the wireless link. The LED for wireless activity shuts off.

Which ticket is the router problem? I noticed a couple of tickets, we should have a master ticket?

Re: LinkSys WRT54GX2 - What the status and what to do

Postby flux113 » Thu Mar 27, 2008 4:43 pm

I too have the misfortune of owning the linksys wrt54gx2 router. The only way I've been able to get my xo online has been through my neighbors wireless router. I could probably live with this arrangement except for the fact that everytime I turn on my xo, it temporarily kills the wifi on my router. Is there a way to keep the laptop from doing this? I thought it might be trying to automatically reconnect to that access point upon bootup, but the ssid is not listed in "home/olpc/.sugar/default/nm/networks.cfg"

Thanks to anyone who might be able to assist!

So after almost a year of crashing my linksys and random AP's around my neighborhood, I finally took some time and found a workaround on the interweb. So, for anyone who has been too cheap to just go out and buy a supported router, here's what I did. I am not too familiar with the technical details and risks of this workaround, so feel free to correct any misinformation in this post.

It seems that this is caused by the way some of our routers handle the information gathered from the Mesh interface in the OLPC. So, this workaround is to disable the Mesh interface completely. The mesh can be reenabled after you go out and buy a compatible router.

Information taken from (http://dev.laptop.org/ticket/5144)

To turn off mesh networking:
1. Open terminal activity
2. type su to gain root access
3. type echo 0 > /sys/class/net/eth0/lbs_mesh

To turn mesh networking back on:
1. Open terminal activity
2. type su to gain root access
3. type echo 1 > /sys/class/net/eth0/lbs_mesh

Looks like this was also posted 3 weeks ago in the ticket for this issue:
