WNA3100 wifisvc.exe keeps stopping

I have a Windows 7 Pro PC (Acer) where it keeps falling off the network with 'wifisvc.exe has stopped' in the event log. Any idea how I can resolve this? [I'm unable to enter anything in the Model box on this page.] Log Name: Application Source: Application Error Date: 08/02/2016 10:05:54 Event ID: 1000 Task Category: (100) Level: Error Keywords: Classic User: N/A Computer: SESCAB-LD015.SESCAB.local Description: Faulting application name: WifiSvc.exe, version: 2.1.0.24, time stamp: 0x53cdc9f5 Faulting module name: WifiLib.dll, version: 2.1.1.20, time stamp: 0x55a6273a Exception code: 0xc0000005 Fault offset: 0x00003486 Faulting process id: 0xae8 Faulting application start time: 0x01d1624e90f6ff66 Faulting application path: C:\Program Files (x86)\NETGEAR\WNA3100M\WifiSvc.exe Faulting module path: C:\Program Files (x86)\NETGEAR\WNA3100M\WifiLib.dll Report Id: 8a07b318-ce4b-11e5-a38a-c03fd5545539 Event Xml: 1000 2 100 0x80000000000000 37153 Application SESCAB-LD015.SESCAB.local WifiSvc.exe 2.1.0.24 53cdc9f5 WifiLib.dll 2.1.1.20 55a6273a c0000005 00003486 ae8 01d1624e90f6ff66 C:\Program Files (x86)\NETGEAR\WNA3100M\WifiSvc.exe C:\Program Files (x86)\NETGEAR\WNA3100M\WifiLib.dll 8a07b318-ce4b-11e5-a38a-c03fd5545539
