[10b7:6000 (rev 11)]

Post by Spacelvis » Mon Mar 19, 2007 6:42 pm

Hi!

First of all: Nice distro! Debian-compatible with multimedia and codecs right out of the box! Nice!

I have however run into problems with my wireless card. I'll insert some code below to show what I'm talking about, but to make a long story short: My wireless card (3com 3CRSHPW796) won't connect, and it doesn't even locate any networks. Ndiswrapper recognizes it ok, but dmesg says "eth1: Egads! TX ring almost overflowed. Dropping frame."

I dualboot this laptop (a Compaq Evo N610c) with another OS (yes, I'm ashamed, but it's XP) and the card works like a charm there.

What can I do?

Output from mintwifi.py:

Are you using DHCP or static IPs ?

Error-message in /var/logs/messages

Post by Spacelvis » Fri Mar 23, 2007 10:22 am

I'm using DHCP, but I get the same error-messages if I try with static IP:
eth1: Egads! TX ring almost overflowed. Dropping frame.
It seems to me like there's something wrong with the driver-support in Mint; I use the exactly same driver in XP. Shouldn't the driver be named something else than eth1?

The driver is netrw796 through ndiswrapper. Eth1 is the name of the interface..

It is possible that the same driver which works in Windows doesn't fully work in Linux. Did you follow the mintWifi guide to find alternative drivers?

No, I don't think so. I had this card with this driver (though with another interface name... I think it was wlan0) working in Vector Linux, which is based on Slackware.

I'm pretty sure something is wrong here, and my best guess is that the error lies in this version of ndiswrapper or the integration of ndiswrapper with the rest of Mint Linux.

But since the card just supports 10 Mb anyway, I guess I'll be buying a USB-stick based on the rt2500-chip to get around this problem and increase the bandwith.
