For those with battery drain / wifi issues

Many of you have found a temp fix related to exchange email accounts, this is not for you and I'm glad you have found something that seems to be working.

For those of you with battery oddities, something new to try...

See what security protocol your wireless router is using...is it WEP, WPA, WPA2, etc.

If you are using WEP, try changing to WPA/WPA2 and re-associate your iPhone with your wireless network.

IMPORTANT: Changing this setting on your router will disconnect all of your wireless network devices so only try this if you've tried everything else to this point and your phone is still acting up.

I've spent more hours troubleshooting over the last couple weeks than I care to admit. I noticed that both my routers at the office and at home were still configured using WEP protocol (older/insecure standard). I reconfigured my office network this morning with WPA and updated the configuration on my phone.

Well....................since doing this my 3GS is acting normal again (normal standby drain, not warm, wifi status bar icon not staying on constantly, etc.). So far NOTHING else has worked for me - restore as new, toggling various settings on/off, evaluating certain apps, reset settings/warnings on phone and in iTunes.

I'm curious to know if it makes a difference for any of you as this issue is certainly 'outside' of the phone itself but would make sense as some incremental firmware releases in the past have caused issues when connecting to different wireless networks.

Please report back if you try and after you've had a fair amount of time to evaluate. May just be another shot in the dark but so far it's peaked my curiosity.
