Hi All,

I've just moved from a Vodafone data cotract (using a PCMCIA/Cardbus data card) to an O2 data+voice contract (using my Sony K850i mobile).

Download rates from Vodafone were regularly 50-60Kb/sec. Download rates from O2 seem to peak at 15Kb/sec. My phone indicates I have 3G coverage, good signal strength, and is also displaying a 'H' icon; the Sony manual doesn't explain this but i assume it's indicating HDPSA.

I've tried connecting to the phone via USB *and* bluetooth and using both o2web and o2wap usernames. My connection is consistantly faster than GPRS but well below the advertised rates of 1.5+Mbit. Data transfer speed remains constant regardless of protocol used (http, ftp, ssh etc). Edit: I've also tested download speeds using the phone's built in browser - with same results (ie, the bottleneck isn't between the phone and computer).

I haven't previously had much joy with O2 technical support, so I'm hoping someone here can help!


Regards,

I've now spoken to O2 tech support and they can confirm I'm in 3G coverage, and I should be seeing 100Kb/sec speeds. They couldn't offer any suggestions as to my problem :(

Connecting to the GSM modem in the K850i and issuing the command ATI7 results in:-

Modem Configuration Profile

Product Type Terminal Adapter
Interfaces Bluetooth, RS-232, USB
Options OBEX, PPP, RLP, V42bis

OK

I've also tried the following commands (which I found listed on an OSX support site):-

AT+CGDCONT=1,"IP","mobile.o2.co.uk"
ATE1

Which has made no difference at all :(

Would anyone have any suggestions?


Thanks,


Steve

r99 would give you 300kbps... the fact that you are using HSDPA is slowing you down because the bottleneck is between the Node B and RNC. the yonly have 1 E1 and that simply isnt enough

meh.... o2 3g is not really 3g as 3g is intended!! i get a good signal outside, none at home... not really a problem as i have broadband at home... it does seem to me though that o2 3g is just a way of boosting their GPRS services, nothing more :rolleyes:
