WIRELESS network adapter FAILURE on Vista ONLY AFTER SLEEP

1. My network has ALWAYS failed upon RESUME FROM SLEEP using a WIRELESS
connection via a NETGEAR WN121T wireless-N USB 2.0 adapter, but NOT when
using a wired Ethernet connection.
2. It also works perfectly from BOOT via the WN121T wireless connection with
my NETGEAR DG834N draft 802.11n (and another 802.11g) wireless modem/router
on Windows Vista Ultimate, both with and without the SP1 Release Candidate.
3. But upon resumption from SLEEP, the wireless n/w connection has ALWAYS
failed: attempting to re-connect to the network fails, and Device Manager
reports for the WN121T that “Windows has stopped this device because it has
reported problems (code 43)�.
4. The only remedy is to REBOOT.
5. The consequences of this are twofold:
- firstly, Microsoft-recommended sleep mode is consequently irrelevant
as a
reboot is necessary anyway to re-establish the wireless connection,
- secondly, as no wireless connection appears to be maintained during
sleep,
Windows Update, backup and other important maintenance via n/w cannot be
scheduled during sleep.
6. The RELEVANT Vista system settings & status are:
- ReadyBoost: active with 1860MB
- WN121T power setting: “Allow the computer to turn off this device
to save
power� is unchecked (i.e. blank)
- Power plan:
- wireless adapter: “maximum performance�
- allow hybrid sleep: “on�
- hibernate: “never�
- WN121T Drivers: always latest (fails with both Microsoft
& NETGEAR).
7. (NON-RELEVANT factors would appear to include that the motherboard has no
disks directly attached (the 1TB of RAID10 disk storage is provided via an
OEM h/w upgrade to an LSI 8308ELP MegaRAID board), as the failure also
occurred prior to this upgrade – albeit prior to SP1 and with the drivers
then available in July 2007.)
8. It seems clear that this issue is either a GENERAL FAILURE IN MICROSOFT
SLEEP FUNCTIONALITY FOR USB 2.0 WIRELESS NETWORKS, or a SPECIFIC ISSUE IN THE
NETGEAR WN121T DRIVER NOT ACCOMMODATING THE MICROSOFT SLEEP FUNCTIONALITY.
Either way, it would seem a NETGEAR DRIVER v MICROSOFT SLEEP issue.
9. This issue has been repeatedly reported to Microsoft for some 6 months
via Problems & Solutions and more recently via the SP1 Release Candidate
reporting facility, without resolution.
10. CAN YOU HELP?
- Have you experienced ANY wireless adapter failures ONLY AFTER
SLEEP on
VISTA (regardless of adapter)?
- Have you experienced ANY NETGEAR WN121T wireless adapter failures
ONLY AFTER SLEEP on VISTA?
- If so, have you reported them, to whom & with what response?
- Do you know of any remedies?
