Heya Ken,
Sorry I missed you the other night. I was at work and thought it would be quiet enough to give a hand..... but alas It got busy.
Anyway- obviously I missed some of the things that have been done ( but I did see the curious abrupt end to one of the help sessions that night
? )
Anyhoo.... one thing I thought of was, when I saw the session where you were attempting to enter the password ( passkey) on the dud puter, is that I'm wondering if the router has a different encryption protocol than your puter. In other words the router may have been set up with WEP protocol and your puter with say....WPA-PSK protocol.
So you might have been typing in the right 'network password' but just not the right protocol.
I made this booboo a few years ago and took me a week to sort out.
Have you got a name for the 'dud puter'?. I dont like calling it dud.
Are you familiar with getting to the home page of the router? On mine I go and open up firefox and type into the address bar 192.168.2.1 .
From there I can see ( via navigating through the menu ) which device ( puters/ mob phone etc) are connected to the router.
I just think ( this happened to me ) the dud puter had a conniption. Reset some stuff and made the router think its there but not
.
Hence the connecting/disconnecting...
I'm not an IT dude but have played with puters for a loooong time ( build my own) but that doesn't mean I know all and what I have just written might not be a solution, just another possibility
I dont know why the device manager had that yellow warning sign on the router....
A suggestion for that would be to remove the card from your puter. Start the puter and try and remove the drivers from the system.
This might sound silly, but reboot the computer a few times ( but in between try and access the net - just let it give you the error msgs of not being able to connect to a network and cxl/close the warning boxes)
Then re-install the card ( maybe in a different slot if available). Re-install the drivers and .......hope.....
Thats all for now....yes a lot to digest including the other helpful posts that could be solutions.....
Mate...good luck and happy days
