Solved!

wifi upgrade for hp6735b

HP Recommended
hp6735b
Microsoft Windows 10 (64-bit)

Hello everyone,

 

I hope you can help me with the following issue.

I've been looking around for an upgrade on the wireles lan card for my old machines a hp6735b and a hp 15-ba071nd.

 

both machines have, to my understanding a bios whitelist, so can't plug in any module as far as I know.

 

can any of you advise me about possible configurations that may work here?

 

many thanks in advance for your help!

 

Best regards

You're very welcome.

 

Yes, the Realtek cards are lousy. 

 

I have two HP 255 G7's with the RTL8821CE's installed and knock on wood, I have not had any problems with either notebook and I am always reading the horror stories posted about that card on the forum.

 

I keep waiting to turn one of them on and have the wifi not work, but I have had them for almost 2 years now and not one issue.

 

But that would be your only option if you want a direct swap upgrade where both the wifi and bluetooth work.

 

If you want a better card, then you will have to use one of the Intel cards in the service manual and give up Bluetooth.

 

You are correct on the 6735b Broadcom card...should have 144 MBPS on the 2.4 GHz wifi band and 300 MBPS on the 5.0 GHz wifi band with an excellent signal.

Hi:

 

Your 15-ba071nd does not have a BIOS whitelist, but most likely it only has one antenna wire connected to the wifi card currently installed.

 

So, open up the notebook and see how many antenna wires are connected to the wifi card.

 

If there is only one, then there is only one AC wifi adapter you can upgrade to and have both the wifi and bluetooth work with one antenna wire...

 

Realtek RTL8821CE 802.11 ac 1x1 WiFi + Bluetooth 4.2 Combo Adapter (MU-MIMO supported) HP part # L17365-005.

 

You can find this model on eBay, or Ali Express,

 

https://www.ebay.com/sch/i.html?_from=R40&_nkw=L17365-005&_sacat=0&_sop=15

 

The card will have the same 72 MBPS throughput as the original wifi card on the 2.4 GHz wifi band, but on the 5.0 GHz wifi band, it will have a max throughput of 433 MBPS when you have an AC router with an excellent wifi signal strength.

 

If your notebook has two wifi antenna wires connected to the card, you can install one of the Intel AC cards listed in chapter 3 of the service manual.  I would get one that has the HP part number for best results.

 

The Intel 3168AC is a newer model than the 3165, so that one would be my first choice.

 

HP Notebook PC (AMD) * Models: 15-ba100 – 15-ba199 * Models: 15-ba000 – 15-ba099 * Models: 15-bf100 ...

 

The 6735b does have a BIOS whitelist, and according to the service manual (chapter 3), there is only one dual band wifi N card you can upgrade to if your notebook only has a single band wifi card installed...

 

c02030223 (hp.com)

 

Broadcom 4322 802.11a/b/g/n WLAN module  HP part # 487330-002 

 

See if you can find the card on eBay by searching by the HP part number.

 

You must get one that has that part number on it or it will not work.

 

In other words, not any Broadcom 4322 802.11a/b/g/n WLAN module will work...just that specific part.

Hi Paul,

 

thanks for your reply!

 

the 15-ba071nd indeed only has one antenna.

so i could only go for the realtek card; from current realtek card i can say that she really behaves like a diva ))

works only when she wants and has severe moodswings )) will this card that you proposed be any better?

 

and for the 6735b  with the broadcom card; do you have any idea about the speed of this card?

from what i could ready online that is (only) 300 mbps -is that correct?

 

sorry for all my questions, thanks in advance for your reply.

 

brgds,
