Laptop came with Broadcom 4313GN 802.11b/g/n 1x1 Wi-Fi Adapter. It has Broadcom 20702 bluetooth adapter. Not sure if its build in to the wifi card. I'd like a dual band better card. I have WNDR3000 Netgear dual band router. This adapter connects only at 65Mbps max. with 2.4n. Any successful upgrades? Please help.

Thank you for quick reply. It's not the one I was hoping for.
Looks like HP degraded their wifi cards. (I have HDX16 with intel 5100 card that is 4 years old and I get speeds of Up to 300mbps on 2.4n and 150mbps on 5G)
HP Software and driver downloads for my dv7-6c23cl lists only drivers for Ralink 2011 802.11 b/g/n WiFi adapter not Broadcom.
Another curious think is that i can't find parts on HP site for my laptop - it shows 'not found' when I list my s/n.# or my p/n#. Is there other way to access parts list or service manual for this laptop under the different name?

You're very welcome.
You can look at the service manual at the link below and in chapter 3 you will find an illustrated parts list with all components you can purchase with the HP part numbers.
Then to buy a part, you can enter the part # in the site below in the applicable box.
When you see the wireless cards available, the dual band card you see is only for notebooks with Intel processors--and it doesn't matter, as the part number for that card is incorrect and nobody knows what the right one is.
Changing a wireless card in an HP consumer notebook is nothing short of a nighmare due to the BIOS lock out of any cards not listed in the service manual for the specific model notebook.

Thanks again Paul, you saved me a lot of time surfing for answers. The service manual will help. Looks like the best alternative is a nano usb wifi adapter.

You're very welcome.
If you want a 5.0 GHz network adapter, that would be your only option with that notebook.
There are ways possibly to modify (hack) the BIOS to allow for any internal wireless card to be installed, but I don't know how to do it, nor where to find the info to do it, or if it can be done on your specific model.
There is too much risk involved with such things.

I agree, there are posts about modded BIOS - to much trouble and still did not work for some. I'd wait for HP bios updates and some people are experimenting with different wifi cards. Hope someone will find the correct dual band card for this laptop in the future
I will try to setup guest network on my router with the n protocol only to see if it will improve the speed.

Yes, you definitely need an 'N' only option to chose and a 20/40 MHz frequency.
It is not the least bit unusual for you to get 65 MBPS out of that adapter. If you're lucky you get 72 MBPS.
All of mine are that way on the 2.4 GHz mixed mode setting on my Linksys E4200 router.
My 300/450 MBPS capable cards get 144 MBPS and 150 MBPS capable cards get 65 or 72 depending on the model.
