Thanks for the response
My Sony laptop is a VPCS111FM with bios R0280Q3. This is the stock firmware, there have not yet been any updates from Sony.
I've have been playing around with this issue some more. I've had a bit of a breakthrough, sort of.
I find that if I adjust the Wireless Adapter advanced setting "Wireless Mode" from its default value of "6. 802.11a/b/g" to "2. 802.11b" the problems are partially improved.
With this setting, I no longer see a flood of messages in the Event Viewer, and correspondily the Wireless Display with the Push2Tv is improved.
However, when watching a video or listing to music, I encounter frequent audio drop-outs. The video continues to play. In these cases I must pause the video and wait for some time before resuming. These drop outs occur about every 3-4 minutes making Wireless Display frustrating and impractical to use. Also, connection to my NAS over the wireless is very slow while using Wireless Display; I see transfer rates only around 250Kbs making watching movies / listing to mp3s impossible from the NAS.
Another prehaps related note, I find that the wireless card is very slow to re-connect to the base station after resuming from Standby. It takes a good 5 minutes to reconnect. During this time, the Windows status shows "Connecting" and then "Connecting to the network is taking longer than usual".
Thanks in advanced for any suggestions. I desparately wish to make this configruation work.
Update: I've found that Intel has released updated Wireless Display software with a corresponding firmware update to the Push2TV box. Drivers can be found here:
The current version is 1.2 with firmware version 22.214.171.124. This update is not yet available through Sony.
This update has made a significant improvement to the quality of Wireless Display through the Push2TV box. I am no longer seeing the freezes and audio drop-outs as reported previously.
However, I do see the errors in the Event Viewer when the wireless adapter is configured for 802.11a/b/g mode.
But thankfully the Wireless Display software now seems usable to me.
If anyone has any ideas on the other issues, your help is appreciated.
I would like to bump up this issue. I was too hasty when earlier thinking the problem was fixed.
I believe there is a correlation between content of videos being watched and the drop-out problems. In videos with fast action I tend to experience more drop-outs.
There is a related thread on this issue on the Netgear support site: http://forum1.netgear.com/showthread.php?p=263785
Netgear released a "critical patch" to Intel's wireless driver with a revision of 126.96.36.199 :
http://kb.netgear.com/app/answers/detail/a_id/13040and an update to Intel Wireless Display revision 188.8.131.52 :
Any ideas are very welcome.
I'm getting the same events in my event log (lots of 5002 and a few 5005), but I'm not using Netgear Push2Tv. My setup is as follows:
- Linksys WRT54GL wireless G router with up-to-date DD-WRT firmware
- Sony VAIO Z with Intel 6200AGN connected via wireless
- Synology DiskStation DS410 connected directly to the router
The only time these errors occur is when I'm listening to music or watching video that is stored on the Synology NAS. I access the files via a mapped network drive. After a few freezes, the adapter permanently loses its connection to the wireless network and I cannot reconnect. The only solution is to reboot (logging out does not help).
Here's hoping for a solution. Thanks!
Well I'm a moron. I assumed my Intel Centrino Advanced-N 6200 AGN wireless adapter driver was up-to-date after trying to update it via the adapter properties. No new drivers were found. But then I used the Intel driver update utility and found a new driver, which I installed and now it seems like my problem is resolved. Sorry for the confusion.
