 |
|
Hi,
I recently bought a new laptop (Toshiba A215-S7422). And I'm having trouble setting up my soundcard and wireless. One main problem is that nowhere on the website could I find detailed specs of my hardware and I had to do most of it by searching, probing my hardware, trial and error etc. But as it stands now, I am facing the following problem:
2. Wireless
This is much worse actually. I can't follow the wireless HOWTO because the section on "Network device support ---> Wireless (Non HamRadio) ---> [*] Wireless LAN drivers (non-hamradio) & Wireless Extensions" that they mention is simply not there in my kernel (gentoo-sources 2.6.22-gentoo-r Is this something that has been discontinued in later versions of the kernel?? However, I did compile ndiswrapper, and add the driver for the RTL8187 but when I try to load the ndiswrapper module, I get the following:
| Code: | # modprobe ndiswrapper
Killed
#
|
however, and lsmod shows ndiswrapper as running at this time, and if I try to modprobe ndiswrapper or modprobe -r ndiswrapper the command just hangs and doesn't return me to the shell untill I do a Ctrl-C. Any help/suggestions on this one?
Thanks,
Shanth
PS: I'm sorry if there's a howto or an earlier post on this, but I wasn't able to find one anywhere. I followed the gentoo-wiki HOWTO, but it doesn't really talk about this problem anywhere

what does ndiswrapper -l say? What about lspci? And dmesg?

Does that give any clues?

Same problem here. I got a USB-Realtek8187 and emerging "rtl8187" throws "CONFIG_NET_RADIO not set when it should be".
I guess I just have to wait for some answer here... |

Is CONFIG_NET_RADIO set in kernel config? If not, set it 
But as for the OP, you could either use the "rtl8187" driver, or you should do ndiswrapper differently. It appears that that is the wrong driver, given the lack of "hardware present" in ndiswrapper -l. Make sure that you compiled ndiswrapper with the usb USE flag, and that you get the latest driver for Windows XP for your card directly from Realtek (preferrably)

For me, ndiswrapper was working fine until a few days ago when I upgraded the kernel. Now, the module is killed each time I try to load it. I suspect that it is a bug, either in the kernel or in ndiswrapper. I haven't found a solution yet, but the problem may not be specific to your machine.
P.S. Once a module is killed, it remains in the list when you run 'lsmod' and you cannot remove it without a reboot, because the kernel thinks the module is still in use. So your problem is with ndiswrapper getting killed, not with the subsequent stages.

This is a problem with the latest version of ndiswrapper. And I suspect that you probably emerged ndiswrapper as well as switching to a newer kernel. I think ndiswrapper-1.48 should work for you. Unfortunately for me, it's still not working even though ndiswrapper loads properly. Actually when I do ndiswrapper -l
| ndiswrapper -l: | # ndiswrapper -l
netrtuw : driver installed |
I think it should say something like device detected or something, but it doesn't do that for me, and that is my problem

I don't quite understand the problem that you are facing: does a modprobe ndiswrapper still result in a Killed message, or were you able to solve that?
Ndiswrapper does not support all wireless cards. You've probably done this already, but did you check on the ndiswrapper site if your card is supported, and secondly, did you try getting the driver for the card from their website instead of elsewhere?
P.S. You were right, downgrading to 1.48 did solve the problem. Thanks! |

Am still stuck with the same trouble. I found a [url="http://ubuntuforums.org/showthread.php?t=571046&page=5"]related thread[/url] on the ubuntu forums, and picked up the drivers from http://www.datanorth.net/~cuervo/rtl8187b/, and compiled them. However when I try to insmod them, I get the following error:
| Code: |
# ./wlan0up
insmod: error inserting 'ieee80211_crypt-rtl.ko': -1 Invalid module format
insmod: error inserting 'ieee80211-rtl.ko': -1 Invalid module format
insmod: error inserting 'r8187.ko': -1 Unknown symbol in module
|
What do these errors mean? And has anyone on the forums successfully configured RTL 8187b wireless USB networ card?
Thanks

I have the same laptop and the same problem. I've tried the 2.6.23 rtl8187 driver to no avail. I also found a "patched" driver which is supposed to work, but I'm unable to load it without getting "Unknown symbol in module" errors.
Needless to say, I'm frustrated.
