Laptop behaving badly from hibernation
802.11 temperamental

 4:16 pm on Aug 19, 2004 (gmt 0)

I'm not sure if this is a general issue with 802.11 or if it's related to my setup. Maybe someone can give me a pointer.


HP/Compaq laptop
PC 802.11 card by D-Link
Access Point/ADSL modem combined - also D-Link

Rebooting from a "hibernated" state almost always results in wireless networking not working. It finds the connection to my access point, and I get the bubble message telling me "connected to TJ signal strength excellent" but I have no networking.

It looks to me like it's not even trying. The 404 errors in the web browser, and the error messages in Outlook appear way too fast to give me the impression it had a go at connecting.

A clean reboot (no hibernation) cures it.

It's almost like it connects to the AP, but doesn't get a valid IP addy from the DHCP server or something similar?

I find it irritating because I love the hibernate facility and use it all the time.

It works fine about 40% of the time.

Any ideas?

Have had similar problems on a similar set up. Sometimes it is possible to "repair" the connection. (R click on the wireless icon and then click repair). Other times it takes a cold boot, like you say.

Never have figured out what is going on.

OK, thanks for that and real interesting - a "repair" fixed it just now when I booted from an earlier hibernate. I guess it went and grabbed a new IP addy from the DHCP pool.

I don't have a "lease-time" set in the DHCP server, I always thought they would last indefinitely if that were the case. Maybe they time out if not in use?

I'll try a static IP addy on the PC Card and report back in a few days.

I have the same exact problem... Sony Vaio, Linksys G wireless card and router.

The quickest way for me to fix it is by disabling the connection, then enabling. Pain in the a. I'd love to hear if someone knows the way to fix this.

There was this MS KB article I remember from when I had this problem: "Wireless Connection Unavailable" Message After Computer Resumes from Standby [support.microsoft.com]

Thanks Bill, although that article seems to be related to USB networking devices?

I'll try the other trick - disable and then enable.

Setting it up with a static IP made no difference whatsoever.

I have the problem occuring quite often from hibernation but rarely from standby.
