Broadcom WiFi issues after sleep/hibernate

[smartminion]

This has been an ongoing battle that I have yet to make any progress on.

When coming out of sleep or booting back from hibernate the wifi will not connect to a network.

The error upon trying to connect to a found network is:

Windows was unable to connect to {network name}

After a hard reboot I can connect to any of the networks.

Tried disable/enable the wifi adapter, adjustments to power management settings.  Tried fresh installs with various broadcom drivers, with and without power management settings, etc.

S10-3T N470, 2GB

Fresh install of Windows 7 Ultimate x86 (also tried x64)

Broadcom 802.11n Network Adapter

Date: 10/23/2009

Version: 5.60.18.41

Hardware ID: VEN_14E4 DEV_4727

Power Management disabled (Device Manager - "Allow the computer to turn off this device to save power UNCHECKED")

The networks I've tried are both home and work:

Home: AT&T UVerse 2Wire, Linksys WRT54Gv8 w/ WPA2-AES

Work: Apple Airport (unknown security, likely WPA)

Both work with Dell Latitudes, iphone, windows mobile with no issues

I'm fairly technical and knowledgeable but I haven't found what would be causing this issue or others having similar problems.  I'm afraid if I can't resolve this soon I'll be retiring the S10-3T - which would be a real shame - so much potential but an unreliable wifi is a problem for me.

Perhaps the best solution would be to replace the Broadcom with another wifi that provides more regular drivers (intel) but I understand the bios has a very limited whitelist of allowed components (really lenovo?!).

Thanks all - GREAT forums - very very helpful/interesting discussions

There will be a new driver for BCM4313.

Version: 5.60.48.35

But I don't know when will lenovo release it.

Because this card also use at other notebooks, you can google it and found out where to download it.

I will try this issue with my S10-3t.

The Wireless AP that I use is Buffalo.

Thanks for the lead - I'm seeing a lot of posts reguarding linux and will keep looking for a win7 32-bit download for version 5.60.48.35

If you get a chance I would love to know if you have any issues coming out of sleep/hibernate.

Thanks again

I can't duplicated this issue with BCM4313.

Version: 5.60.18.41

Wireless AP: Buffalo WZR2-G300N

Security: WPA-PSK AES

Wireless AP: Linksys WRT300N

Security: WPA2-PSK AES

Thanks for the update chiaying - much appreciated!!

Hey all -

Just wanted to post a followup...  The problem is still occurring for me.  Per Chiaying's suggestion I tracked-down and have been using the BCM4313 driver for the broadcom wifi but when coming out of sleep it still gives the "Windows was unable to connect..." error message.

Any additional suggestions would be much appreciated.  Against my better judgement I'll be installing the Lenovo power-management tools to see if that has a more reliable effect on the broadcom.

Thanks-
John

similar issues exist within win7 with other cards especially the latest Intel cards: clarify the configuration setting for the wifi adapter and that both 2.4 and 5.2 bands are set to automatic and that your router is also set to automatic: depending on the router, the intel cards will or will not pick up 20 or 40 mgz signals

sorry if this sounds confusing but it is an issue with the card and the router playing nice and the combinations are great: a lot of it is trial and error so that by the time you sort it, you are unable to explain what you did!

I guess what I am suggesting is that it is the settings within the card and the router more than a driver issue (not that some drivers are not worse than others)

hope this helps you problem solve if these are areas you have not yet adjusted and tinkered with

Thanks lgsshedden - That does make sense - I'll check routers at home and work and try and find a good "match".  I'm just worried about when travelling when I don't have access to the router settings - I guess in those cases a reboot isn't THAT big a deal - just annoying   Hopefully Broadcom (and Intel) will get their drivers updated for win7 soon

Thanks - I'll report back after some testing for any lurkers!

Hello,

Anything say: "There will be a new driver for BCM4313.

Version: 5.60.48.35"

I found this version on Acer laptop (Google search for "5.60.48.35").

I tested today and work fine.

Trying this version.

Hello all

I tested Acer new driver for BCM4313, Version: 5.60.48.35.

On same network, after sleep, work Ok

If I change network when computer sleeping(go on work, etc...), on wake don't connect.

Maybe Lenovo version correct this driver.
