Have you tried hooking it up hardwire to the router? That would be the first thing to try. Hopefully you have downloaded the proper drivers for the unit. Assuming drivers are correct the next thing, and you have likely done this, check network settings in control panel. It could also be a security/firewall setting. The first thing I would try would be as I mentioned, hooking it up to the router, IF it hooks up you should be able to troubleshoot from there, from within windows, to a degree, or from your ISP page.
After reformatting my mother's laptop, I discovered that I needed to install specific drivers for the notebook (chipset, video, & wireless LAN). After installing said drivers, I clicked on the network icon on the bottom right-hand side of the task bar, my wireless router appears. I click connect under it and then I have to type in an 8-digit pin from the router label and I proceed as needed. However, moments later it says that "Connection to the network was unsuccessful. Windows can't get the network settings from the router."
I've hit a wall. I do not know what else I should do. The brand name of my router is "Belkin N Wireless" and my mother's computer is a Lenovo SL410 if that aids in solving my problem. Please no ******** answers or smartass remarks. If anyone could give me some advice/assistance I would greatly appreciate it. I need help in solving this problem ASAP!!
