As Internet is working fine in Safe Mode, the issue is related to Windows. The Windows might not be configured properly or some file might be corrupted. Hardware should be fine. Try browsing the Internet in normal mode. If it is not working, I would suggest the following steps: 1. Check if you have 'Dell Stage Remote' application installed on the system. If it is there, uninstall it. For steps to uninstall an application, visit the link below: [URL] 2. Maximize the performance of 'Wireless Card' installed in the laptop: - Right-click the 'Computer' icon on the desktop or from the 'Start menu'. - Click 'Manage'. - Click 'Device Manager'. - Click the + sign to expand the 'Network Adapters' entry. - Right-click the wireless adapter and click 'Properties''.[IMAGE] Note: Your system might have been shipped with one of the following cards: • DW1703 WiFi/Bluetooth 4.0 combo card • DW1704 WiFi/Bluetooth 4.0 combo card • DW1901 WiFi/Bluetooth 4.0 combo card • Intel 2230 WiFi/Bluetooth 4.0 combo card • Intel 6150 WiFi/WiMAX combo card - Click the 'Advanced' tab to configure the advanced settings. - Select Power Management, uncheck Default / Auto, and move the slider to Highest / Maximum Performance.  Note: If the slider is already at Highest / Maximum Performance, move the slider to another setting and then back to Highest / Maximum Performance. - The following adapter settings can be found under the ‘Advanced menu’. Please match the settings with the values given below: 802.11n channel width for band 2.4- Auto (not in 20 MHz only) 802.11n channel width for band 5.2- Auto (not in 20 MHz only) 802.11n mode- Enabled Fat channel intolerant- Disabled Roaming aggressiveness- Highest Throughput enhancement- Disabled Transmit power- Highest Wireless mode- 802.11a/b/g - Click 'Ok' to save settings and re-check the wireless performance.  If you continue to face the issue, I would suggest that you back up the data (Pictures, Music, Videos, Documents, Favorites, and MS Outlook Emails etc.) and reinstall the Windows on the system. Let me know if you need any further assistance. I will be glad to help.
I have bought Dell inspiron 14z ultrabook, windows 7 home edition. I have problems with connecting to internet. My internet connection is lost after 2-3 minutes. I read somewhere that this was due to latest updates to macafee. I have tried the using some guidelines how to fix this issue which was posted on dell support website. Despite following all steps I am still having same problem. I have also run diagnostic test on my laptop and every part is working fine. I have unistalled antivirus but I am having same problem (no internet action after every 2-3 min). My wireless router is brand new, works absolute fine.  Please suggest some ideas ASAP or else I have to return this laptop back to dell and get another one, but not dell! Thanks
