FIX ReadyNAS NV+ Windows 7 wifi problems
I finally fixed things by changing the MTU size to 1430 and turing of TCP Autotuning.

start, run, cmd
netsh interface ipv4 show subinterfaces
you will see default windows setting of 1500 on both the wireless and ethernet network cards
Need to set MTU of 1430 for best performance
ipconfig /all 
gives more info
note of the exact names of the network devices
netsh interface ipv4 set subinterface “Wireless Network Connection” mtu=1430 store=persistent

All DONE

To say it bluntly why the Hell wound Nvidia a multi – million dollar company not spend a few extra bucks
what would it cost maybe 400-500 dollars to pay the programmer to send an email when the NVIDIA
raid has an error, say a disc failure.

I have searched and searched and could not find any way to fix it to notify you on raid failure.

Until I came across the free program “PA Server Monitor”
http://www.poweradmin.com/servermonitor/

http://www.poweradmin.com/servermonitor/ServerMonitorfree.exe

Install,
Configure your computer
and add email notifications

Now you can add the specific error numbers, and make it email you

All done
