Our first recommendation is that you check with your computer manufacturer if the Intel® Dual Band Wireless-AC 7260 is compatible with your system. They can also provide you a list of all wireless adapters that are fully compatible with your system and if they have any specific drivers that might resolve this issue. Intel does not support integrations which is the replacement of the original wireless card installed by the OEM (Original Equipment Manufacturer). You can get more information by access this link: Intel® Wi-Fi Products — Regulatory Information Regarding Hardware Installation or Upgrade
On our best effort to help you, we also recommend that you disable the Bluetooth* if not in necessary use as both WiFi and Bluetooth* use the same same antennas and this could impact on the performance because Bluetooth* and Wi-Fi transmit in different ways using different protocols, interference can occur when Wi-Fi operates in the 2.4GHz band. Also, disabling the power saving functions and keep the adapter working at its maximum performance can improve sudden connection speed drops.
1 - Go to Control Pannel >> Hardware and Sound >> Power Options >> Set the High Performance and apply to default settings.
2 - Check the Change Plan Settings >> Wireless Adapter >> Power Saving Mode and make sure both on battery and Plugged in are set to maximum performance.
Here are some links that can help you improve your performance as well.
let us know if this helped you.
The problem turned out to be operator error.My laptop is compatible with this wifi product. All drivers, are up to date. High performance maximum settings are applicable as they always have been. I had already checked with my manufacturer with regards to compatibility. And forums to figure out setting etc.
Blue tooth was/is disabled etc etc.
I had too many webpages open, and it showed a loss of actual data when testing speed etc.
It runs at 59Mbps now at 30 feet... Not bad..
