Every time I try to connect to my wireless network it permanently disappears?

[CameronBates]

I recently got a new desktop computer with a TP link TL-WN781ND wireless adapter. Everytime time i go to connect to my wireless network it immediately makes my wireless network disappear for my computer and every wireless device in the house.
In order to find it again i have to completely reset the modem/router and do the same thing all over again.
Please Help me fix this.

Try a firmware update on the router. If that does not help, try a different wireless adapter on the desktop. If that ALSO does not help, the next step would be to try a different wifi router.
