Hi, Have you tried resetting your laptop to a time before this issue started via a Windows 7 Restore Point?  If it's a setting or software change this restore point may help resolve whatever is causing the problem. I would also make sure, when you're resetting the router, to make sure you let it sit for at least 30 seconds to one minute before plugging the power back in.  You may need to do it a few times to clear out it's memory to be able to connect.  Also, have you updated the drivers for the wireless card?  What driver version is currently installed in the system?  You can go to our support site, key in your service tag, and click on Drivers & Downloads to find the driver for your wireless card.   Lastly, have you tried to clear out the wireless profiles that are currently stored in your system?   If you delete the current wireless profile (which is controlling your connection to that router), reboot your system, and try connecting again Windows will rebuild the profile and hopefully allow you to connect again.  Let me know if any of this helps.  In order to help troubleshoot this more efficiently please click on my Dell Todd username and send me a private message with the Dell Service Tag of your system.  Please keep all troubleshooting and discussions on this open thread so that others can find information they need in order to resolve their problems. Todd
Good day, I have a wireless network connection problem and I ask for help in solving it.What surprises me that this problem appeared suddenly, I used to connect to WIFI properly but two days ago my laptop unable to connect to WIFI anymore. Other devices and computers connect successfully so I think the problem in my laptop.I didn't make any changes on my laptop neither windows,antivirus,drivers.. updates nor installed any new software.Windows troubleshooting detected " router or access point issues."- Resetting the router didn't solve the problem- Network adapter is enable.- Wireless adapter status "works properly " and "up to date." I read a solution in this web-site , that was to change the properties of the wireless adapter but the mentioned changes doesn't appear in my laptop driver.. * My laptop info. :DELL INSPIRON 3521Windows 7 - 64 bitDell WIreless 1703 802.11b/g/n(5.2GHz) Sorry for make this long, I appreciated any help.Thanks in advance.
