My GPSing using Wayfinder is being ruined by my N810 popping up windows asking me whether I want to connect to the list of WiFi signals it has found.
Is there a definitive way to stop it doing this, ie switch WiFi right off until I wake it again?
I have search interval set to 'Never' in the connectivity dialog.

I also find that annoying but it is simple to put it into offline mode. You can flip it back with one button and one tap when you get back to a net zone. it is fun to then watch the 'updating maps' popup after laying down a track and the maps come into detail.

Sorry, I don't understand anything you're saying. You say it is simple to put it into offline mode but don't say how.

Seriously, I live in London. Wayfinder maps are always detailed so I never see 'updating maps'. And I'm looking for the navigation I've paid for, not fun :-)

What happens is that when I'm going to an address in Kensington, say, I can never see the screen for the lists of dozens of wifi routers that pop up. It is dangerous, on the move, to keep hitting the 'cancel' button and it immediately pops up with more anyway.

What is 'laying down a track?'

Does anyone know how I can resolve this problem?

offline mode: tap power button to bring up the menu. Select offline mode. This shuts off wifi and bluetooth and will also save you battery life.

oops, offline mode shuts down BT too so that doesn't help if you are using a BT GPS unit.

Tracking is overlaying a route track where you've already been vs where you're going. sorry, can't help much. I use it for fun so not familiar with wayfinder.

Thanks you gentlemen. Unfortunately, because of the poor lock on of the inbuilt GPS I do use a BT unit, so Wayfinder is effectively no use to me. What an expensive mistake. I wonder if Nokia people have ever used one of their units themselves? I guess not.
I just installed Skype, thinking that it would be most useful to me for texting - at last a keyboard instead of laborious finger pecking at the phone.
Whoops! N810 can't do texting with Skype. Bizarre.
What next from Nokia? How about the Nokia car. Six forward gears but no reverse because they never actually drove it anywhere ;-)

You can always set the search interval to "never" in Control panel -> Connectivity.

Ima, I've always had it set to 'never' but it hunts anyway.

Like any good true dedicated hacker (on a VW station wagon in the '70's)
Park on an incline so you can roll back!!

There's a dedicated enough group that overcomes the problems and there is a whole freakin lot of peeps that don't research the device enough before buying.

There's 10 types, those that understand binary, and those that don't.

Have you tried a long timeout other than 'never'? Might be a bug but if it works then at least there is a workaround. But if you have to use an external GPS instead of the internal then let's call it defective and return it. Or sell it cheap in the buy and sell.

None of us here have anything to do with the "get what I paid for" so we're only here to help if possible. The NIT isn't for everyone that's for sure but it works amazing for the rest of us.
