wireless not working

**ameyap** · 10-09-2005

i have a linksys wrt54g router.. and an hp ze4927ea.. redhat linux enterprise 4 ws

i have installed the latest version of ndiswrapper.. installed the correct drivers.. got my wifi card working (yes got the light up) after updating my linux kernel to support the 16k stacks and disabling the acpi..

now my problem is i get access provider (AP) on doing "iwlist wlan0 scan"

on doing the remaining configuration steps i get everything correct in the command "iwconfig wlan0" but still i am unable to connect to the internet..

the router is setup in WEP mode .. (yes i configure wlan0 for wep) ..

now if somebody is familiar with Kwifimanager in redhat it shows the correct configuration specified but in the bottom left hand side of the box it says AP : UNKNOWN.. whereas in its main window it states the correct Hardware address of the access provider..

now i am fairly new to linux and this problem has stumped me for almost 2 days.. any help will be really appreciated

thanx in advance

hello...

another thing my router is set is broadcast off mode.. that means it doesn't broadcast the essid..

and anoher thing is there seems to be some irq conflict between ndiswrapper and ehci_hcd... now as stated earlier i have put the params acpi=noirq in the linux startup.. but it doesn't seem to be working

here is another output

Code:

&#91;root@localhost ~&#93;# cat /proc/interrupts

NMI&#58;          0

notice the ndiswrapper under 11..
well half the times theres a conflict between ndiswrapper and my enhanced usb.. when that happens the wifi card fails to light up and i am forced to restart linux and hope there is no conflict.. even now i order to paste the above outputs i had to restart linux 2 times.. i think this is really funny/odd.. any solutions to the above problem..

here is the dmesg output when this happens

Code:

note the unknownkey pressed and released is when i am pressing the wifi on /off button

One thing I don't get is why it is using the ipw windows drivers for your card. Your card seems to be connected and everything, but the ndiswrapper error are the first of its kind that i have seen. Hmm, i'd suggest some googling on your part, and i'll try and do the same.

**ameyap** · 10-15-2005

i followed the steps exactly as mentioned on the ndiswrapper site and installed the drivers that they recommended in their card list .. earlier i had tried installing the drivers on my cd but after installation the card light was not coming up.. but i think now this could be due to the irq conflict.. i will remove the current drivers and reinstall my cd drivers just to be sure..
