Installization guide for Intel Centrino 6235 in DV6T-7000 (and probably dv7t as well)

All righty, let me start out by saying that it WORKS! It's fairly easy to install, and it's fairly easy to set up.

The Intel Centrino 6235 is a Bluetooth 4.0, 2x2 wireless card, which basically means that it is the highest possible speed that you will get from any wireless card, unless you decide to go with a Killer 1202.

First off: Where to get it

Ebay is probably the easiest place to get it, but it's about $35, and generally ships from China. That's a long wait. I got mine from shopblt.com. I was able to purchase it for $25 (Including shipping and handling).

Second, installing it. Turn the laptop over, touch something metal (to get the static out of you, and remove the battery. There should be 1 screw in the center of the laptop, near the vents, shown below.



Unscrew the screw and open the cover by pushing the cover towards the front of the laptop.

The wireless card is shown below.



There is one screw in the card. Unscrew the screw. Be warned that the card will pop up when the screw is fully unscrewed, take care not to lose the screw. Pop off the antennas CAREFULLY by pulling the metal part (not the cable) upwards. Take the card straight out (don't pull up towards you).

I had a ralink in mine (no bluetooth). The cards are shown below for comparision.

Next, put the new card in. Ensure that the antenna slots are facing upward. Connect the antennas. Take note that one antenna has a 1 on it, and the other has a 2 on it. Place the 1 antenna in the port that has the label 1, and the 2 antenna in the port that has the label 2. They are color coded below.

Finally, screw it back in. I reccomend putting the screw in the hole first, then using the screwdriver to push the card down and screw it in, as shown below.

Next up, install these drivers from HP.

They aren't for the 6235, but they work fine. Verified to work on my laptop with Bluetooth AND WiFi. Havne't tested out WiDi yet.

Hello

I ordered this card from EBAY
Intel 6235 6235ANHMW WIFI WLAN BT Bluetooth 4.0 Half MINI pci-e wireless Card | eBay

The details in your card are not as shown in the ebay picture.
On ebay is written "Made in china" and ur card is not !

Is it a fake ? the performance will be the same?
I'm thinking bout cancelling the order......

 

I can confirm that these instructions work in a dv7t-7000 as well..
I got my card from provantage and it works great!!

Your link is to broadcom bluetooth drivers .. i really dont know how those work for an intel 6235..
I already had an intel 2230 installed so all the drivers were installed but people coming from non intel wireless cards should use these drivers-
Intel Wireless Driver W/ Widi
Intel 4.0 Bluetooth drivers

 

Do u remember if you had a "made in china" text in the bottom of the white sticker on the card?

 

THANK YOU to everyone in this thread! I just received my dv7t-7000 and was somewhat annoyed to discover that the "Centrino 2230" didn't support 5GHz. So I've been sitting here stewing about that for the last few days until I discovered this very helpful post. I've ordered the 6235 from Provantage even though they're not the lowest price source. They're less likely to be selling "off" merchandise.

BTW, I have gotten what I regard as poor performance from the 2230. It has never synced at anything higher than 150Mbit, though it claims to run at 300Mbit. My access point supports 300Mbit 2.4GHz, so that's not it. Anyway, for $30 it's worth getting 5GHz capability.

 

Will this card work with the HP DV6T F.12 bios? I currently have a realtek card and want to upgrade it to the intel card. Will this card work or is it whitelisted in my bios?

 

It installed well and everything, but now for some reason it is only downloading things at .2 mbps whereas the broadcom averaged about 1 mpbs...

On the speedtest.net graph, it starts to rise then goes straight down to the bottom only to rise and then fall again...

 

I wonder if the killer 1202 works. May buy one off eBay for $50 and test it out.

 

@sailorboy Thanks for the installation guide, took me less than ten minutes to change from 2230 to 6235. Same drivers as before, just a second reboot to activate bluetooth.

 

UPDATE APRIL, 2013:
I found these excellent instructions trying to get more speed from my HP dv7t-7000 (same configuration as above). Bought the Centrino 6235 and installed it. Previous card was Centrino 2230, but the card would not connect as suggested in this post. The drivers linked by in the original article did not work either. It said "no Bluetooth device was found". I searched HP and found they also had the 6235 drivers. I installed that driver (sp58641.exe) and the card comes alive and connects to my network. I went to the advanced setting and switch my channel width from 20 to 40 MHz and other associated settings for 802.11n, etc. The speed of the data transfer is exactly the same as it was before. The speed should have doubled, but it did not...17 Mbps +/- downstream on both cards using 802.11n 2.4 GHz. My 2009 MacbookPro gets double that speed. My internet speed from Comcast on ethernet is 55 Mbps.

If anyone knows some additional tricks, please reply.

PS: The article says the 6235 card has bluetooth, but it does not according to the recommended driver. The HP page with the correct driver does not mention bluetooth at all.
