Aiysha,

It sounds like your connection in Tokyo was at your work office; if so, your company probably uses a Proxy server that sits between your computer and the Internet (it's like a watchdog.)  If this is the case, look under your browser Internet settings for the Proxy settings, and disable it while you're away from the office in Toyko.  For Internet Explorer 6.0 (MS), it's under Tools/Internet Options/Connections/LAN Settings.

Please let me know if you've successfully browsed the Internet anywhere away from your work office.

Diabling unused adaptors and issuing
 IPCONFIG /RELEASE
 IPCONFIG /RENEW
will often help
as somethimes you can pick up spurious WIFI networks or the hotel ethernet is unresponsive.


You don't say if you were in corporate offices, on hotel broadband, or commercial dialup isp.
swittstr is correct about a static proxy, if your lan folks have configured that on your laptop, but without knowing how you're connected to what it's difficult to guess what the problem is.

swittstr,
Thanx for your reponse.
There is no office in Tokyo, I am talking about the connection in a hotel.. I think its more complicated solution then just internet options.. Someone suggested me it has to do with the type of nic card commonly used in US and in other eastern countries. Do you have any such information about nic cards??

Ethernet NICs are pretty standard.
If you're talking about WIFI - 802.11 cards are pretty similar, though the channels in use vary in different countries and is a driver issue.
As you can see in the frequency chart for one of HP's access points ( http://www.hp.com/rnd/pdfs/Country-Approval-Matrix-520wl-8-15-03.pdf ) different countries allocated different frequencies for WIFI.

WHat your looking for are drivers that support "world mode or international roaming".
If they're not available for your card, look at something like Cisco (airnet 350 comes to mind).

IT, Stop Being Called Into Every Meeting

Highfive is so simple that setting up every meeting room takes just minutes and every employee will be able to start or join a call from any room with ease. Never be called into a meeting just to get it started again. This is how video conferencing should work!

If you have multiple network adapters (ethernet, wifi, etc.) disabling unused adapters in Network and Dial-up Connections can sometimes speed up detection of the network you intend to use.

Aiysha,

About the 'Automatic Detect Settings', I believe you should leave it checked (selected), but do be sure that the Proxy Server setting (below Automatic Detect Settings) is NOT checked.

Sense your talking about Internet access from hotels, I'm guessing it's either Ethernet cabling or Dial up (phone line), but I guess it could be WiFi too (I haven't traveled for awhile so I guess hotels could be using WiFi by now.)  Can you tell me what type of connection you're making?

Are you simply trying to access the Internet through an Internet Service Provider (an ISP that you chose) or are you trying to access a corporate network (work) which would imply you're access the corporate network through a VPN (Virtual Private Network) which the corporation set up for you?

It's not only a/b/g - globetrotters need to be aware of the frequency (channel) limitations of region specific drivers.

Hard-wired ethernet is generally autosending 10/100 and has worldwide standard wiring and signalling schemes - shouldn't be any issues here.
