A list of available matching items appears above the search box click Device Manager. To open Device Manager, click Start, click Search programs and files, and then type Device Manager.To resolve this problem, do the following. Any help would be immensely appreciated so thank you in advance. I have tried updating drivers which say they are already up to date, i have run the dell troubleshoot which has made no difference, and i have tried other troubleshoots in the control panel which said it found a problem and said it was fixed however there has been absolutely no change so i am beginning to think that the wireless card may be faulty. I feel that this is not a problem with the router or my Wi-Fi in my home because the laptop i used prior to buying this one worked perfectly and other laptops in the house also get full bars of connection and high speeds in my room however my laptop does not. The wireless adapter works fine when i am right next to the router however in my bedroom it is extremely slow even when there are a few bars of connection and so i am forced to use an Ethernet cable to connect. I very recently purchased the Dell Inspirseries laptop with the Intel (R) Dual Band Wireless AC-3160 however i have noticed that the connection to the Wi-Fi in my home when using wireless is extremely slow and the signal bar fluctuates from 1 bar to 5 and often just disconnects.
