Hi guys, I am just going to bed now, and maybe tomorrow I will have a fresh brain, but I just installed 11.3 to my laptop, with USB WiFi adaptor.
Went like a dream, did the washing up and hoovering during the boring bits (who said geeks aren’t houseproud?) and was connected to the world out of the box, as soon as I selected the NW and put in the key.
So pleased was I with this I thought I would try knetworkmanager…
This was a breeze as well.
Then trouble started…
If I Dmesg|tail the USB is finding and associating with NW, but I cannot ping or use the connection. I have followed swerdna’s walk-through.
On boot I am told "You have changed etc/networkconfig.
How do I work back and correct what I have borked, without a complete re-install?
Are you saying you were running ifup and switched to networkmanager?

since 11.3 is pre-release, all discussions on it should be be in the
forum where testers hang out (so they can find it easily and compare
notes & log bugs):

Hi Caf, & TY, yes that is what I did.
Denver, I am 100% sure this is a bug in my head, not in 11.3, and I would have just as easily made a similar hash of Ubuntu or Windows 7 
I have no problem in 11.3 M7 with network manager, either in kde or gnome.
Why don’t you switch back to ifup then?
!! Sorry did not explain clear enough, I did go back to ifup, no connection with that either, I followed swerdna’s walkthrough, put in free nameserver addresses etc etc, also tried booting to level 3 but no ping working…
Tell Yast to switch to the networkmanager, then reboot and try to logon to the network. I’ve met a couple of times where this was needed to make the changes have effect.
You could also think about disabling ipV6: add “ipv6-disbable=1” to the boot options line.
That’s ‘disable’
Not: ‘disbable’ rotfl!
hmm thanks Knurpht, but I have rebooted dozens of times, with knetworkmanager and ifup, enabled and disabled ipv-6 etc. (I am a recovering windaholic, and tend to reboot after making ANY changes 
I will try with the ipv-6 disable in the boot options though…
Like Caf wrote, disable it, not disbable I like the word though, coming to think about it.
Did you run the command netconfig update -f
I THINK I did, Dale, not sure now, I will have a look at MAN netconfig and try a few things. As this is a 100% fresh install, if it is is broken, no biggie, I can just install again, it would be better if I can find out what is wrong and fix it though 
Well I spent some time on it, tried a lot of things.
I swapped the USB WiFi with the one from my desktop, so it is not that,
It is definitely finding and associating with the network, accepting the passkey, it CAN scan for other networks…
If I use knetwork manager, it reports “connected”
But If I ping anywhere, it says unknown host…
frustrating I cannot paste here easily, I could save stuff to a thumb drive, but don’t want to flood the page with useless stuff.
Can I delete all networking stuff and get openSuse to regenerate from scratch? If so, how do I do that?
Would a repair install be able to reset all networking stuff to defaults to start again?
Are you sure your /etc/resolv.conf did not get overwritten accidently?
I am pretty sure it DID (and not by accident! ;);) )… I moved resolv* to a /bak directory, and tried again. same results, even the new resolv.conf has my additions in it. I also deleted all network interfaces in YAST and rebooted, and configured them again, same result.
Can you ping your router if so and nothing else then do a netconfig -f
I ping the router but get “destination host unreachable”
Configure static IP, use router’s IP as a gateway, google’s public dns’s 8.8.8.8 and 8.8.8.8 and router’s IP as DNS’s. See if that changes things.
Hi Knurpht & everyone else, I was swotting up and googling around for this, static ip setting etc, , I came across this…
cp /etc/resolv.conf.netconfig /etc/resolv.conf
I did it, and bingo! insta connected to the world.
(I unfortunately did not keep the overwritten file, might have been useful to find out exactly what I had done wrong)
I had not manually or deliberatelty edited the file, but, I had obviously borked something in there in my search for a solution…
Maybe you could all keep it in mind in case other unskilled peeps like me have similar difficulties…
TY for your kind help and attention up until now, more stoopid questions will follow!
the command, from konsole, solid-networking --commands will give a list of options for enabling networking just fyi
