There is no 5ghz wifi channel visible on my  Windows 7 laptop using a Linksys AC1900 dual band router (2.5 ghz and 5 ghz).  Both network connections show up on other devices in the house like the I-pad and I-phone. Also, the 2.5 ghz shows up on all devices in my house. Please advise if there is a setting required or other change necessary on the laptop?

Check to see if your laptop model supports the 5GHz band.  A lot don't.

I suspect your laptop simply doesn't have a dual-band adapter.

2,5GHz (aka WiMAX)?
Can you elaborate with make and model of your laptop and it's network card?

Be aware that if your laptop came with a 2.4GHz-only WiFi adapter, it's often not possible to merely buy a dual-band card to replace it, because the built-in antenna is not likely to be compatible with the 5.1 to 5.8 GHZ band. It's no easy task tearing them apart far enough to mount a couple dual-band antennae between the LCD's foil shielding and the laptop's cover, get the mini coax routed through the hinges, et cetera.
If you decide to buy a dual-band adapter for it, I would recommend a USB adapter, such as this Edimax EW-7822UAC adapter from Newegg.

After further research, the Dell Inspiron 1501 laptop only comes with the one antenna, 2.4 Ghz. Learn something everyday.

In theory you can plug dual-band express card wifi adapter, with good luck with bluetooth (i have 2 expresscard slots in older laptop - one makes USB3, other wireless BGN, i had bluetooth already, and even infrared...)
