T42 How To Change Wireless Power Setting

[stuffinder]

Hi,
I'm just leaving on a trip during which I expect to be connecting to marginal Wi-Fi networks. I know I can change the signal strength of the Wireless Radio transmit signal but can't remember where to find it! Last time I saw it was set to Medium, I believe. I'm running access connections 4.0. TIA

Open Access Connections. Go to Locations > Manage Profiles... > highlight your profile > choose Profile Action > Edit... > Wireless Settings > Settings... (under 5. Advanced configuration) > dropdown menu under Power save Mode:.

If my experience with a Cisco Aironet card and accompanying software applies, Power Save mode doesn't determine straight signal strength. Adaptive Power Save modes (CAM (constant aware mode), High, Low, mezzo-mezzo) determined how/when a card would shift from full strength to lower-power while monitoring the net.

In the Aironet Client Utility, max power Save would be low power until there was traffic and switch to high, and CAM would shift to low until there was traffic, shift to high, and stay on high for a certain period, then drop down after inactivity.

As far as the IBM and Intel mini-PCI cards, I'm less informed.

AC 3.81 and 4.0 both offer a separate signal strength setting, in % increments. I think it's in the same dialog that Gomjabbar referred to, on the left. In interested in the details of the power save mode, but so far haven't been able to lose connection like I did with the Aironet utility set on Max Power Save. (Granted that as 802.11b, so flakier compared with 802.11g.)

In AC 4.0 with an IBM OEM version Intel 2200BG card, using the latest Intel Wirless driver, there is no provision for setting much other than the gross "power save mode". The Transmit Power level setting are greyed out.

Cheers,

There is a way to do it; from what I remember whilst poking around my system...I managed to find it in the Thinkpad Configuration Program when it brought up the Hardware Configuration and Drivers list. If I remember correctly, there should be around 5 levels; I will check it again.

I neglected to mention I have the 11a/b/g Wireless LAN Mini PCI adapter.

If you have the Intel wireless (i have the 2915 a/b/g) you can go to the Advanced tab in the device manager properties for the wireless device. Here theres a bunch of options including transmit power (however, default is already maximum). Some other useful options are preferences to set network band/channel as the preferred (for example i'd rather connect to an a network rather than b or g if i can).
