When I'm at home I have a really bad data signal. I barely get standard GPRS signal... No EDGE or HSPDA. But I have a WIFI router 5 meters from where I sit with my phone and laptop. My laptop have full signal strength to the WIFI net, so I guess my phone has that too.
When I try to access anything from the net on my phone it takes a really long time before it starts downloading the site/file/data. When it at last starts to download the data it goes really fast (WIFI speed). If I'm at my brothers place, which have the same kind of router, I have full HSPDA connection and it starts downloading at once. But much faster then it would through HSPDA. So I'm quite sure it downloads through the WIFI connection. Also If I manually turn of my data connection it starts loading data directly.
It's like it first trying against the data connection before it falls back on the WIFI connection.
Is this how Windows Phone works? Or can I change this somehow? It's really annoying that I have to wait for 20-30 seconds before it starts loading the webpage I've navigated to... And when it at last starts it finish in just a second or so. And manually turning of my data connection each time I come home seems like a pretty crud workaround.
I read these threads:
Does Windows Phone prioritize between using a data plan and wi-fi connection?
How does Windows Phone consume cellular data?
How can I tell whether I'm getting data via Wi-Fi or phone network?
But non of them really answered my question.
Edit: My phone is a Samsung Omnia W (thanks for noticing that I forgot to mention that... :) )
