Terrible WiFi Speeds with Intel Centrino Wireless-N 2230


Hi Everyone,

I have a HP ENVY TouchSmart m6 Sleekbook with a Intel Centrino Wireless-N 2230 as my wireless network adapter. I have 200mbps internet, but when I sit right next to my router I only get about 100mbps download speeds. Then when I move over about 20 feet to my dining room table (where I keep my laptop normally), I get around 15mbps. I can open up a different laptop and get 200mbps download speeds anywhere in my house. I'm not a computer expert, but is this most likely an issue with my network adapter? I just tested out my internet speed while plugging into my router with an ethernet cable (as opposed to wireless) and I'm getting 220+ mbps download speeds.

Is it possible to upgrade the wireless network adapter on my laptop? If so, do I need to check for compatibility or anything? I'm not even sure where I would get started and how I would know what to get.

Also, if it means anything, I am using Windows 10. I've always had relatively bad wifi speeds with this laptop regardless of the operating system though.

Thanks in advance!

Intel does not support integrations which is when one changes the original wireless card that came installed by factory for another one. However, if your intentions are to change this adapter, the OEM (Original Equipment Manufacturer) must be consulted as they are the only ones entitled to provide the list of compatible and certified adapters that are right for the type of system you have as they are the ones providing full support. Please check the links below for further information on this matter.

6 - Regarding Windows*10, it provides its own inbox driver for the Intel® Centrino® Wireless-N 2230. In cases like this, we highly recommend that you also contact your computer manufacturer to check if there is any updates available on the part that could help. Nonetheless, you can also disable Bluetooth* if there isn't any peripheral that depends on this connection as it uses the same antennas causing impact to your wireless connection.
