Ralink 802.11n Not Recognizing 5GZHz

[JBeuchert]

I have a Ralink 802.11n Wireless LAN Card with a driver just updated, version 5.0.9.0, date 11/27/2012

The card connects fine to the 2.4GHz network, but not my 5GHz.  I have another laptop and the wireless card views both the 2.4 and 5 networks just fine.  I am connected to the 5 on my laptop and iPad...

Running Win7, all patched.  I have tried moving the channels around on my router with no effect.  I want to get this HP machine on my 5G network because I have all the kids on my 2.4 and turn off the wireless at 10pm, I need to use my PLEX server running on this box after 10pm.  Any help would be greatly appreciated.

Thanks!

Hi:

Most likely the Ralink card in your notebook is a single band (2.4 GHz) card only.

Most wireless cards in HP consumer notebooks are only single band cards.

Very few are dual band.

If you let me know what model Ralink wireless card is in your notebook, I will confirm my opinion.

I actually have an HP Pavilion p6540f Desktop PC, not a Notebook. The card is integrated on the MB and it looks like it is a Ratech RT3090 HP P/N WN6602RH-H1-1A

Hey Paul,  I think I figured it out.  Was looking at the specs on the card and it says it only works on the 2.4GHz band.  Thanks for your help

Hi:

The Ralink RT3090 is a single band card.

AFAIK, the card is not integrated into the motherboard

It is a standard notebook wireless card mounted in a PCIe x1 slot by an adapter.

The product specs page for your PC describes the wireless networking as a 802.11 Wireless b/g/n PCI-E Mini card.

Anytime you see a wireless card's description as wireless b/g/n, that will indicate it is a 2.4 GHz card only.

A dual band card will be listed as a wireless a/b/g/n or a/g/n.

My recommendation if this is very important to you is to purchase an external USB dual band wireless network adapter and disable the current one in the device manager or physically remove it if you can/want.
