rc3 Wifi WEP problem
« on: April 04, 2009, 04:01:37 PM »
OK here is the problem,
                               Elonex ONEt+. On original OS got Wifi working OK using 128 bit WEP. Installed 3MX rc3. Connects OK to router with open connection. Connects OK with MAC filtering on (its posted elsewhere, the MAC address on the label on the bottom is for the Ethernet not the Wifi).
Entered same WEP key and offset, WLAN setting on DHCP, etc as per working settings on original OS.
On trying to connect it gives "connect network" message for about 30 seconds and goes to "Not Connect".

Have also tried with static settings with no joy.

Any thoughts or suggestions please. Have I done something silly?  ???

Update:
          reinstalled latest Elonex recovery file and worked OK, went back to 3MX rc3 and same problem.

Update,
          tried 3MX rc1.1 and it works. Will try next with rc2. Have seen various wifi problems mentioned on here that appeared after rc1.1 is this one of them? Hope someone has a fix as liked the look of rc3.

Yeah i don't know what the deal is, but wpa and wep work fine for 93% of the people who use rc3. Just seems 7% have bad luck. Not really sure there is a cure as it really isn't an issue since they both work just fine most people. Wish i had a better answer, but i dont.  :-\

Cheers

OK,
     Thanks for reply. I know nothing about Linux (good start then  ;D ) but this smells of an unititialized variable or hardware register.
I have seen, and dropped, similar clangers in C for microcontrollers. Not initializing variables stored in non volatile memory leads to code that runs only on certain machines. Also not initializing hardware where registers on most ICs start up in the "right" state or reading back undefined bits which usually are "right".
This LLL is one of a batch , others that have been tried do work so maybe this is an indicator.

Not a surprise now but rc2 doesn't work either.

I was having problems with wi-fi (128bit WEP) in rc3. It generally manifested as severe problems resolving addresses ("DHCP unable to resolve...") and even total disconnects.

After reading a couple of posts on this forum I changed the wi-fi channel on my router to channel 1. After a reboot it has worked flawlessly since! HTH.

SilverLoz,
             glad the channel change worked for you. Been through different channels, 64,128,256 bit settings. Played around with WLAN settings for static DHCP etc, without luck. Tried latest rc3 final release, no luck. Really odd thing is rc1 works fine as does Elonex flavour OS so hardware / firmware does work  ??? .
There may be the chance to try this machine alongside one that works in a few weeks time.

I had the same problem: rc3.1 on Alpha 400 could not connect to WAP access points.  I was able to resolve it by replacing the following files with ones from the 3MXrc1.1 release:

  • /sbin/iwset  --  I actually replaced all the other iw* files there as well
  • /lib/modules/2.4.20-celf3/kernel/net/zd1211b.o  --  this is the driver

To replace the driver you have to first deactivate it and unload it:
  • ifconfig eth1 down
  • rmmod zd1211b

The system has to be rebooted after the files are replaced.

Cheers,

Nice. Might hopefully work for others as well. Any way you could package up the files into a .zip and upload somewhere to make it easier for people?

Cheers.

I've had problems with setting my epc700 to function as an Access Point (share 3g). The connection always got dropped and the ssid was unreachable after minutes of serving.
Switching zd1211b.o with the version from 1.1 didn't work for me, but i used the original driver from the manufacterer image (trendtac epc700) and it seems to work now.  Let's hope it stays that way!

If you want to give it a try, I've put my zd1211b.o at http://wouter.ru/zd1211b.o and you need to overwrite them in (rename the old one first) /lib/modules/2.4.20-celf3/kernel/drivers-extend and/or /lib/modules/2.4.20-celf3/kernel/net/

btw. I also have a linksys wusb54gc (EU) wifi stick, which needs the rt73 driver (ralink chipset). Does anyone know where to find them compiled for mipsel 2.4.20? Or info on how to compile it?
