Cannot connect laptop to Nighthawk RAX43

[lovely1979]

I have an older Toshiba Satellite C850 (PSCBWC-05600J) with windows 8.1 which I cannot get connected to my wireless router.  The wireless adpater is Realtek RTL8188CE wireless LAN 802.11n PCI-E NIC.  My router is  not showing in the available networks, I don't even see it in 2.4G.  I have updated the wireless driver and still nothing.  I can see the neighbours wireless router (go figure).  Any help would be greatly appreciated!

Oh ya forgot to mention - I have other devices connected to the router and they all work fine except this laptop.

Some of the older devices aren't able to "see" AX networks. 
Its supposed to be backwards compatible but some still aren't. 

You can try disabling wireless AX on the 2.4ghz for your router.

Or you could upgrade the wireless card or even add a usb wireless card.
