Problem with iBook & Wifi after router upgrade

[dougal]

I had my modem/router software upgraded and everything is fine except that my iBook refuses to join my wireless network.

It says Error joing the airport network "xxxxx"

I have tried the following with no success:

Did a Keychain repair
Deleted my network from "preferred networks"
Deleted the associated Keychain
Renamed my SSID
Changed the password to connect to my wireless

Nothing! it still refuses to Join!! Arrrgggg!!! Any help by someone who is more knolegeable than me will really be appreciated.

No idea... I just know that before i had the software of the router/modem upgraded , my iBook used to work perfectly using WPA security.

Software is OS X 10.4.11 Tiger

Yes, so check to see if your router is still on WPA - or switched to WPA2...

It is set for both WPA and WPA2 simultaneously

I have tried WPA+WPA2 and also WPA on its own... None work

With no security it connects no problem

I am thinking the mac must have something stored that needs to be cleaned but no idea.

I did have problems with my iBook at the time in regard to the battery life and the battery clock time gets lost because it loses all power before the time/date is saved.  I don't know if you suffer such power problems, but it was around this time I started experiencing problems with Airport.

I don't use my iBook anymore though as the crappy thin power lead has frayed for the 2nd time now and I can no longer charge it.  Shame its not MorphOS compatible otherwise I could probably buy a new cable and sell it to an interested MorphOS user.

I don't miss the iBook though as its so frigging slow playing videos on youtube and flash... ahhh lets no go there.

I am 100% sure it has to do with the upgrade of my router as it was working perfectly till exactly before i upgraded the router. It doesnt have any clock problems or anything like that.

Do you still have your old router ?
 
Could you daisy chain routers ?

Its the same router, just the firmware was updated.

Both my iPhones still work on my wireless, just my iBook doesnt work anymore.

I don't get it because i set it up as it was before. I tried WPA+WPA2, WPA2 on its own, WPA on its own, tried changing the password, i changed the SSID.

My iBook supports fully WPA as it was previously (up until yesterday) with WPA security.

It makes no sense. And when i turn off security the iBook connects perfectly.

There must be some setting that is remembering something. I need to start afresh but cant.

I cleaned up my prefered networks, cleaned up the keychains, did a keychain repair.

I am stuck

I set my security to WEP instead of WPA and its working fine now.

Very weired!!

Could it be the region? My router says Europe, but my iBook came from USA

The iBook is a G3 800Mhz (2003 model) and the wireless Airport card is 802.11B

When i first bought it, it had problems connecting to my WPA network because it had an older OS X which didnt support WPA. But once i upgraded it to Tiger it worked perfectly with all 3 WPA networks i have at home and also with my WPA at work.

It still works fine with my other WPA networks at home except for the one in question.
