Hi All!

I have a problem with Dell Wireless 1704 802.11b/g/n in my Dell 17R Inspiron 5720. Speed of my wifi connection changing from 5.5Mb/s to 54Mb/s all the time. 

I`m using Windows 7 Ultimate x64 OS. Problem is with wifi card Broadcom 4356, another laptop (HP) has stable speed 150Mb/s. I tried different options of card driver and router D-Link DIR-320NRU,  but nothing have changed.

  Is anyone can help me, please??
