On my Win 7 Outlook 2010, I have no problem connecting to just a basic WPA2 broadband Wifi (of 100Mbps)
in my offsite (ie not at our HQ which hosts the Exchange 2010 server) office & sync/download/send emails.
On my Win XP Outlook 2003 (another laptop), tho it connects to the same broadband Wifi & that very
same laptop could browse the Internet, it often can't connect to our HQ's Exchange 2010 server with
a message at the right bottom corner "Trying to connect ..." for hours. Occasionally it will be "Connected".
Webmail on this Win XP laptop certainly has no issue reading/sending emails, so the Wifi connection is
good. When Outlook 2003 client fails to download/sync emails, I wud immediately connect using my
3G dongle (which is only 1-3Mbps) & cud download/sync emails on the Outlook 2003.
While this Win XP is connected to the offsite office Wifi, doing continuous ping to gmail (can't ping our
HQ's exchange servers as ping is blocked) did not result in any packet loss.
When I'm at home connected to my home's WPA2 Wifi using this Win XP laptop, I never have any issue
with the Outlook 2003 syncing/downloading emails & will almost instantly get the message "Connected"
at the bottom right corner.
I'm inclined to think that my wireless driver has sort of 'compatibility' issue with the Wifi broadband
router at the offsite office.
How do I go about troubleshooting this?
