Hi,
I bought my Inspiron 15R 5520 yesterday evening. Today when I was using my laptop on wireless network then I realized that it's very slow. Then I used application speedtest.net to check the download speed, it's just 9.09 Mbps instead my old HP laptop was receiving 43 Mbps.
I have Network Adpater : Intel Centrino Wireless N 2230 having version number 15.5.7.52 which is latest.
Please suggest me whether I have to ask for change in wireless card? Is there any solution to resolve this issue?
