There's no doubt in my mind that ( at least my) Sg2 has very poor wifi range. After using a 3gs for 2 years, it's painfully obvious that the RANGE of wifi in comparison to my iphone is woefully worse. This was just a gut feeling to me after using the sg2 for 2 weeks, but after installing "wifi analyser" it's clear to be seen.
After spending the whole of this morning in my local town ( Plymouth) walking around to different wifi AP's and checking range I was pretty shocked tbh.
I usually sit outside a cafe on a Sunday morning and have never had problems getting really good speeds on my 3gs. This morning, on my sg2, there was no signal at all ! 30 feet from their router !? Full strength when I was stood right next to it though.
I went to the local o2 shop (200 metres away) and spoke to the chap who sold the sg2 to me. He has one also, so he installed wifi analyser on his phone and we went walkabout. It was fair to say that his phone was maybe a tad better than mine in some places, but in general they wer both the same. ie. poor. Even in the shop, we had to be stood over the router to get a good signal. From 20 feet away it dropped to -60 to -70db on both handsets and jumped up and down rather a lot too.
So, I then went into a Voda shop and the lady in there had a Sensation. She kindly installed W/A on that phone and the results were instantly obvious. The Sensation had maybe -20db better signal then my sg2 and a more solid lock. We then walked up the road to about 50 feet away and the Sensation was still holding a better signal the the sg2. Mine was unusable and hers was fine.
Only problem with the Sensation was (in bright sunlight) that we couldn't see the screen very well at all. Plus point to the sg2 there.
So, where does all this leave us. Well, the manager in the o2 shop is going to have a word with the Samsung rep on Tuesday. I have until Thursday to return this phone which is looking likely now. It all points in the direction of a hardware problem, seeing that initial reports of KE7 f/w sees no improvement in wifi range or strength. I'm on KE2 btw. ( No Kies updates on o2 here yet.)
Below i have uploaded some screenshots to show what I get:
Sg2 directly on top of linksys router
Sg2 8 feet from linksys router
Sg2 20 feet from linksys router
In town, sat right outside the Americano cafe, 20 feet from router which is visible through the window
30 feet away from Americano router, note that the Americano has gone!
Any comments?
