is it possible to replace the Broadcom module with an Intel 7260 HMW (AC)? HP ENVY K153nr wi-fi

[Alinka1995]

Hey! i have a k153nr laptop? Very low internet connection speed 20-35 Mb / s. , I do not know why. On another laptop, the speed is 100 Mb / s. Wi-Fi module Broadcom BCM 43142 b / g / n. The router operates in the same 2.4 band. What could be the reason? Tell me please !!! and is it possible to replace the Broadcom module with an Intel 7260 HMW (AC)?

Hi:

The max throughput the BCM card you have is 72 MBPS with an excellent wifi signal, so the speed you report is a little low.

Check the actual connection speed (not the download speed), by going to the Windows control panel>network and internet>network and sharing center.

Click on the wireless connection shown there and see the connection speed.

I think that there is only one wifi antenna cable connected to the Broadcom wifi card, and the Intel card would need two.

If your notebook has two antenna wires connected to the Broadcom card, then yes, I think that this model Intel 7260 will work.

Intel Dual Band Wireless-AC 7260 802.11 ac 2x2 WiFi + BT 4.0 HP Part # 710661-001

Search by the HP part number, not the model of the wifi card.

Below is the link to the service manual, where you can find the wifi card removal and replacement procedure.

Please tell me what is the difference between models with different PART # 710661-001,756753-001,784639-005 on the same Intel 7260 AC wi-fi module model?

[Paul_Tikkanen]

Unfortunately, that I would not know.

I think as long as the card has an HP part number or HP SPS number, it should work.

[Alinka1995]

I wonder how they differ))). Thanks for the help. I have already ordered a module with the number 710661-001. I will establish how I get it and let you know the results!

[Paul_Tikkanen]

You're very welcome.

Looking forward to reading about the results of your notebook's wifi upgrade project.

I am surprised to learn that your notebook has two wifi antenna cables connected to the currently installed Broadcom wifi card.

[Alinka1995]

Yes, two antennas. Why are you surprised?

[Paul_Tikkanen]

Usually the single band Broadcom cards only had one antenna wire connected to them--even though there were two terminals to connect the wires to.

Apparently the card works with just one antenna connected to the Main antenna terminal.

[Alinka1995]

that is, you want to say that I have two antennas, but one is used because the work is on the same band? Is the second antenna just idle?

[Paul_Tikkanen]

No, the second antenna provides better reception-- it is called antenna diversity.
