Everyone who has a UIQ 3 phone... Just do a simple test... Open SE website on ur phone, in the default browser... Then go to press release and then the media section... Download a pic and see how long does it takes...
I did this with my P990 a long time back... And guess what??? I download a 3MB Picture from SE site and it took just 15 seconds... This means that the download speed was almost as fast as
2Mbps, just what I have on my laptop... (If anyone can't calculate just PM me)
But I am very sorry to say the speed during browsing is too slow... I think the reason might be either the phone's processor or it's the browser... But it's not the WiFi that's slow... The WiFi is fast enough and in India we only have 8Mbps as the highest speed at present... So even though I would prefer a wifi b/g than only b, I am satisfied with the speed just not the browsing experience...

The important difference between b and g is in the way that they work. G will give a better signal and better performance in an enclosed space - its much less susceptible to interference from outside sources and less prone to having problems with the signal being reflected by walls etc.
Symbian seems to have something of a problem with WLan transfer speeds though, there is an interesting article somewhere on the net which details transfer speeds outside of the web browser on a N95. They did not get full speed from the connection, and indeed found some interesting performance drop offs with certain packet sizes.
As to the original poster, I'd ensure I was on latest firmware myself, WLan seems to be somewhat faster on the newest firmware, at least it seems that way for me.

Here's that paper. (SymSmb development
has started to recruit for betatesting for the UIQ version, btw

).
In any case, it seems (I'm guessing) like there's a theoretical maximum of 5.5Mbps on the p1. And that translates into a throughput of about 2,5Mbps (320kb/s) in absolutely ideal circumstances. But (guessing again) it's likely that bus- speed, error correction and pauses, overhead, memory recovery and so on - and perhaps a weakness in symbian with returning calls, or perhaps an implementation weakness in the way external calls need to be resolved completely before negotiating a transfer again, and things like that - you'll never get all the way to that speed. Or, what you really get is peak speeds on somewhere near the maximum - and then drops for whatever different reason, and averages *wave* somewhere below that.
..some 250Kb/s isn't exactly bad on a mobile, though. Compare with the n95 in the linked test, for example (which tests in ideal conditions).. And, I mean, the n95 has about twice the processor speed, a newer modem, more power drain, as well as a quicker internal bus..
In other words, the only reason to get G- support for a phone would be if your network doesn't support b- standard. And, btw, the only reason a G- network is typically more resilient to noise, is that it pours more signal into it, and generates larger peaks on the signal. And then surviving more interference in practice. There's not really all that much about the g- standard that's inherently better than the b- standard. I mean, there's been other handshake and encryption algorithms introduced together with the g- standard that's very useful, and so on, but other than that..

Another thing - about the initial post: 1,5Mbit (megabit per second) is about (1,5*1000)/8 = 188Kb/s (kilobyte per second). And depending on the weather, that's about what you'll get on the p1 as well.
..You know, it wouldn't suprise me if it turned out that all the current mobile phones use the same chips in their modems..

Well, that makes kinda sense - when you think about it.

@Nipsen, just a small correction:
1.5 x 1024 / 8 = 192 KB/s
Also, the main disadvantage of not having "g" connection available is not speed but that all devices connected to a particular access point start operating at 54 Mb/s as soon as a single "b" device connects. Because of this limitation a growing number of access points allow only a "g" type connection.

I can't believe Se is still stuck with the old standard. That much about a 'for runner' in the field. And let's not fool ourselves - if your internet connection is anything above 2mbit the 'b' standard in a portable device (i.e. cell phone), will slow you down ! I find that even the 'g' standard in a mobile device (n95), will 'bottle neck' if the internet connection is more than 8mbit. Of course, distance and environment can change this figures even more towards 'south'. Nokia will bring out (in a few months) the long awaited WIMAX-mobile standard. We can only hope - things will improve -.

I think there are two pars to this problem. Firstly, the board the P1 is built on simply does not have enough bandwidth. That's the reason you won't se HSDPA fitted to these phones any day soon.
Secondly, it appears the WLAN code was compiled in debug mode, because I see all kinds of debug printouts coming over the serial port from the WLAN stack when I debug Escarpod... maybe they fixed that for the W960, which is why it is faster.

lol. Really? I.. suppose we should be thankful someone.. at least seems.. to be working on it?
..just one thing about the g-standard thing - most new routers, even very cheap ones, can run in asynch. Instead of reducing the connections for every device on the network to the lowest speed connected. And it's not like you don't get speeds down to a crawl(below b-standard) once in a while just because every connected. unit is a g-standard device. Or like you actually get 54Mbit transfer in practice on anything. Or easily get 10Mbit throughput on wifi without a bit of luck.. And it's pretty common to fit mobile devices, and laptops, with power- saving modems which won't get past the really high speeds.
So - in my opinion, anyway - we shouldn't really have any reason to complain about not getting, you know, soaring wifi speeds. At least not until it's easy and cheap to produce low- power wireless modems that have no weaknesses, and easily connect with any standard, improve the standby time, cure insane in-laws, improve your sun- tan while you sit behind the desk, and things like that..
