Intel(R) Wireless-N 7260
I have got a computer mouse with communication by bluetooth.
When I want to dowload something or generally my wireless network card (7260) is heavily used my mouse slows, cursor jumps (and something like this)
What is it caused by?
Sorry for my english.
Even though WiFi and Bluetooth* are designed to coexist in the 2.4 GHz band, the main cause of the issue could be related to interference; however, there are different causes for interference besides your WiFi connection.
