Broadcom bcm43142 802.11 bgn wifi adapter

[Ajay84]

Hi, i am using this laptop quite a long but facing issue with wifi connectivity, post start it frequently loosing the connection or wifi speed degraded not sure why as i have updated the drivers and my other devices are working fine on 2.4/5 Ghz. This laptop card doesn't support 5 Ghz band so i was looking to upgrade the card to dual band.

While doing research i came to know that this laptop has single antenna while it for dual band required two.

Could you please let me know how to install 2nd antenna and compatible wifi dual band card for the same.

Is this card a dual card for wifi and bluetooth?

Welcome to the HP Support Community.

For the issue with the connectivity try these steps:

Right-click on START --> Device Manager * Expand Network Adaptors * Right-click on the Wireless Adapter --> Properties --> Advanced tab * Select the Roaming Aggressiveness and change the value to be Highest * Restart the computer. If that does not help, please try the below steps * Right-click on START --> Run --> Services.msc * Get to the Standard tab at the bottom of the window * Search for WLAN AutoConfig -- right-click --> STOP * Restart the computer

I must let you know that HP does not recommend upgrades or hardware changes as the device is equipped with parts that perform at its optimal performance by design, that said, the upgradeable parts listed by HP articles are purely for your ease, as the decision to upgrade will be at your own discretion.

However, to help you with the compatible components, I would need the serial and product number in a private message.

Let me know if this helps.

Have a great day!
