Another security key plea

[lasttombstone]

Please be patient with an old guy who doesn't know much.  Bottom line is I can't connect to the extender network.  I keep getting the 'security key" thing.  None of the numbers on the back of the unit work.  I have tried the reset followed by the supposed number on the back but still no luck.  I'm lost.  Considering just getting another one and starting from scratch.  Any assistance will be greatly appreciated.  Thank you.

Have you tried hardwiring into the extender for setup? If you hardwire in a laptop/desktop to it, make sure to disable the wireless on the device you connect with so the device doesn't default back to the wireless

I have not but will try.

With the extender plugged into he outlet, the cable goes from the router to the modum?  Then what?

[plemans]

connect your pc/laptop directly to the extender via ethernet cable.

Disable wireless on the device you're connecting to the extender so you can ensure the pc/laptop isn't defaulting back to wireless during setup.

OK.... extender is connected to the PC by an ethernet cable.  Wireless is turned off to the PC

so try going through setup then.

Obviously this is too deep for me.  When I try to log in to the extender network I get an "out of range" message and it is a foot from the tablet.

I tried another laptop and it says "can't connect to this network"

[lasttombstone]

And the PC says the same thing

[lasttombstone]

Am I correct that the cable is to the tower and not the modem?

[lasttombstone]

Must go.  Will check back as soon as I can.  Thank you for your help.
