Working, But Not Working Laptop WiFi

[ZMan2021]

System: Laptop Latitude E6520
Adapter: PCI I think from what I can see, it’s a slot on the mobo.
OS: Windows 7 64-Bit
ISP: T4 Connection
Router: NetGear WNDAP350 Wireless N Access Point 22 Laptops Max No other wireless devices allow, MAC Restricted
ISP or Windows itself

I have a laptop out of 22 that stop connecting to network (A), while it can connect to other networks (B), (C), etc. When I connected to network A it says there nothing wrong and auto drop after trying to connect with it. I flush the IPS, DNS, memory test, ram test, power test, delete the network driver let it reinstall and see if that work. Replace the wifi card, reimage the HD with the current year OS. Still same problem.

Just was wondering if anything else can help me fix the issue. I'm dry on ideas.

You said the network is MAC restricted, do you have the MAC inputed correctly for the wireless adapter.

Yes, it was working before and it just die out with this network. It can connect to other networks and have no problem at all. It's just this one it was useing. Which leads me to think it has to do with some cach or something keeping the netwok or something.

Undestand their latest firmware is 2.1.7 do you have it? Since the bandwidths are 2.4 & 5 do you have any wireless phones? They may intefere. Is the router close to the kitchen? The microwave may interfere. Where is your router located? Are the channel selection set in Auto? Try to set it to a selected channel like 10 or 11.
