My other laptop (Asus, Lenovo) do not have such a problem and can transfer data via WIFI streaming even if the Bluetooth mouse is connected to them and used. Performance degradation is some expected when Bluetooth is used, but what is not acceptable, it is that no data shall not be transferred for a period of several seconds and even in the case where no bluetooth device is actually connected. If bluetooth is enabled (but no bluetooth device is connected or prominent) WIFI performance is severely degraded.
If bluetooth is disabled the WIFI performance is good and there is no delay in the transfer of data. In the end, I found that the problem is related to activated Bluetooth which is necessary for the connection of a wireless mouse. I have tried other laptops and their connection works fine, so the problem lies in the Satellite A665-13W and its wireless adapter. I tried to measure the performance of data transfer on LAN and found that the problem is not only related to my internet connection. 11 g, and 802.11n) and the problem persists.

This makes services like Skype unusable because for a while, I have good network connection, allowing you to make a video call even but quality then connection drops less than 1 Mbps (in fact hold) so even audio is not working and call either disconnects or connection back to full speed for about 10 seconds until what the quality decreases again. These shortcomings last several seconds and occure probably 3 times per minute. The laptop connects to my router and can reach network high speed, but then long time ago when there is no flow of data over network connections. I have Satellite A665-13W with wireless Broadcom 802.11n network adapter and use the latest BIOS and drivers (for Broadcom is version 5.60.48.35). I have hit a problem with WIFI performance and need help to find the solution. Satellite A665 - 13W WIFI slow when activated Bluetooth
