Slow internet download speed

[FCD]

I have home internet service at 400mbps download speed.  On my HP laptop the internet download speed maxes out at about 150 mbps on both wifi and wired connection.  I think the hardware on this laptop is designed for much higher speed than this.  Other devices in my household have much faster download speeds, most over 250 mbps and some nearly 350 mbps.  I have McAfee software on my laptop and the other devices are Apple without virus protection.   I think all my drivers are up to date and I have done a scan of my laptop with the McAfee software and have not found any bad stuff. 

Suggestions for why the slow speed on this device welcome.   Could the problem be the McAfee software?  

Thanks

Hi@FCD, Welcome to the HP Support Community!

Signals are affected by the type of WIFI card you have - WIFI cards are NOT equal.

• The less expensive router might lack the support necessary for the best performance of the wireless card in your computer.

Example: An older router that only supports 802.11g is not going to provide faster than 54Mbps -- even if you have the best card you can buy in your computer.

• The opposite can be true as well - a good router cannot provide better service than the computer's wireless can support.

Example:  If the card in your computer is 802.11g, then even if you have a Router capable of speeds upwards of 300Mbps, you are only going to get 54Mbps.

The speed and range are limited by the weakest link in the chain.

• 802.11n is faster than the "g", but it too can be slowed down by walls, metal furniture, and other obstructions.

• Moving your equipment, even a few inches, might make the difference to an Intel® 802.11b/g/n/ac (1x1) Wi-Fi

AND

• The same might be true for an 802.11n router that has a weak (underpowered) antenna
