A few days ago my AT&T/McAfee Internet Security Suite updated itself to a new version (can't find the version number anywhere). Ever since, I cannot access the internet after waking my computer from sleep mode unless I reboot my computer or reboot my DSL modem. Is there a fix?
Windows Vista Home Premium SP2
P.S. I tried McAfee's on-line chat support which was useless.
Follow the below steps to overcome this issue.
Step: 1 - Open Properties window of the Network Adaptor (NVIDIA nForce 10/100/1000… or available network adaptor) from the Device Manager as shown below:
(Navigation to Device Manager: Click Start > Right Click Computer > Select Properties > Select Device Manager on the left pane)
Step: 2 – Uncheck the box beside “Allow the computer to turn off this device to save power” as shown below:
Step: 3 – Change the network adapter advanced settings to below values as shown below & (Wait about 2Mins):
Sleep on disconnect: Enabled
flow control: Disabled
interrupt moderation: Disabled
ip checksum offload: Disabled
jumbo packet: 9014 bytes (this might have no effect for you)
ALL large send offloads: Disabled
BOTH low power: Enabled
network address: not present
priority & vlan: priority Enabled
receive side scaling: Disabled
speed/duplex settings: auto
