According to a message from Nokia several months back, the 10mW/100mW setting shouldn't be an issue at all. The 10mW setting is only for those countries where there are legal resons for not using 100mW. Dropping to 10mW won't even help on battery usage, as the data is sent in bursts anyway (if anything it'll make it worse).

What you should look into in that section is the timeout settings. Some routers have trouble with the shorter timeouts introduced in newer versions of the OS. I believe there is a setting for that in that same section - but I'm not on OS2008 so I'm a bit vague on what it's called.

Longer timeouts will work with all routers, but your N810 battery will be drained a bit faster (although not critically so - after all, the longest timeout used to be the default setting in OS2007 a year ago)

(Note - the timeout is about power saving - the 10mW/100mW setting is _not_).

Might this be the Power saving setting with options On (maximum), On (intermediate), and Off?

Wow! I tried it out on the way home, and setting the Power saving setting to On (intermediate) did the trick. Thank you so much!

Glad TA-t3 was able to help you, and it was something simple!

Next time you have a problem don't wait so long to ask
Does it fix your 800?
And what do you want for your 800?

Yes, that's the one. The "power saving" here is directly related to the timeout setting - that is, how quickly the Nx00 will go into wi-fi power saving mode. The current default is 200ms I believe, while in the past it was 1000ms. With the shorter timeout setting it drops into power saving mode faster, which saves battery. But some routers don't work well with it, particularly some types which can support multi-SSID's at the same time, and some others that are plain broken. Mostly it works very well though.

A-greed.

I'll check, but I'm guessing it will work the same. I was thinking $200.
