For some reaseon, when I am connected to the AC adapter, my wireless network connection improves considerably.  When I unplug it (Battery is fully charged) the connection is stop and go.  I spent a couple hours troubleshooting the network before I realized this.  But the soon as I plug in the AC, big difference.  And the soon as I unplug, problems.  Does anyone else have this problem?  I am playing with the power panel to try to fix this, but still can’t improve network performance when it’s running on batteries…

As my wireless router is just located below my TR, I didn’t notice this problem.

After reading your post, I did observe some lower signal reading when the AC is not plugged in.

signal strength without a/c on best performance mode : 53-61
signal strength with a/c on : 61-66

Does it change at all when you are further away from the wireless router?  I have turned off the power panel entirely and am still experiencing a huge difference.  It’s almost impossible to navigate through this site when unplugged, but I fly around with the AC plugged in… ?

definitely when further away from the wireless router, my signal strength drops.

If you go into Device Management and double click on your wireless network card, under the advanced tab there is probably a Property called Power Management or something, try setting that to maximum or off and see if that makes a difference..

I’ve had a similar problem with some Centrino laptops in the past and this seems to fix it.

It seems to be some sort of over zealous power saving attempt by whoever wrote the drivers.

Thank you!  Changing the power management setting helped considerably. 

All these power management settings are really a pain in the ass.  From this problem, to setting the monitor to very dim, etc.  And you have to search for the different settings in different places.  What’s the point of making the battery last longer if you don’t have any performance?

Anyway, thanks a lot for the help.  Working great now! D

:D

It’s all about marketing, because battery life is one of the biggest factors in choosing a notebook. Look at the reviews, the TR is one of the slowest in its class, but with one of the longest run times.

Thats why I’m glad I picked the TR.  I do not game too much on it or do any heavy graphical work.  The battery times were a huge factor when I purchased.  They will be a huge factor again when I upgrade.  This is why I am kinda cooled down about the U50/70.  I hope the next model in the U series improves in this area. :wink:

hmm… i’ve never had a dropped signal… infact my school said the TR has one of the best signal of its class.  he says the TR picks up a signal farther than any other computer.

oh, and by the way, my school uses a cisco router

i’m not sure about whether it’s the best around.  But I’m sure it performed better than a powerbook titanium, compared it with my friend’s PB.

But what setting are you using under Power Management?  Mine is working great now under Power Mode CAM (Maximum), but was terrible at Automatic.

I sure looked and couldn’t see any power management stuff in the harware manager property windows. I thought I heard that one could change the transmitter power level somewhere.

I think the problem might be the reduced processor speed when on the battery profile. Under those conditions all those little programs in the system tray may be eating enough processor cycles to cause problems.

Just had my own experience with a connection problem, mine was with Bluetooth. Wandered over to visit some friends and was going to show off the bt link to my cell phone and do a little internet demo. The connection starts then a 777 error telling me there’s a modem problem. Come home to try to fix it and plug in the AC adapter. Give it a test, and it works. I’m going to play with a few things and report back.

Go to Administrative Tools>Computer Management>Device Manager.  Select Network Adapters, then Double Click your Wireless Adapter.  There will be an Advanced Tab.  On it, one of the Properties is “Power Management.”  The value is probably set to “Automatic.”  Change to “Power Mode CAM (Maximum).”

Please let us know about the Bluetooth, I haven’t had a chance to try mine yet.

Thanks, I keep forgetting that stuff’s there, gotta keep it out of the hands of the kiddies I guess. Given all the other things that can be screwed up, why hide it in administration.

I’m beginning to think it was a GSM network error or logjam. I’ve had the phone go into eternal “connecting…” when trying to access WAP sites. I’ve been running on battery for over two hours now and logged in with no problem a dozen times. (just tried again, testing Murphy’s Law)

As for the bluetooth, I’m beyond pleased. My Bluetake mouse showed up today (I got the white one). The mouse works great and the size is perfect for traveling. Other than my original battle getting it configured, the link to my SE t68i works flawlessly. Float’s Mobile Agent worked right out of the gate.

My BT connection is at 110kbs 2x better than dial-up and is comfortably fast for browsing. There’s a link utility called “Toggle Images” that turns off graphics, so all you have to transport over the web is the text. If there’s an image you want to see, simply right-click on it and specify “show picture”. Nifty, given A$&$ charges by the bit…

One last thing…  I am so grateful I got the internal BT (for all it’s failings in the headset arena). BT is ready to go when the TR is. Overpriced,  but worth it to me. Besides, the mysterious blue light adds something. :D
