I am planning to get a laptop with Centrino M technology, but I know nothing about the WIFI, can anyone please tell me what additional device is needed for WIFI connection, do I need to buy any card or antenna? Do i need to register an account with TMnet (hotspot package)?

Centrino laptops have the WIFI chipset built in, as you'll find out when you see the laptop. Always make sure what's in the package - if you don't know what you're looking for you may get swindled, and that's not cool.

As long as you can see the WIFI logo on your laptop, you should be good to go.

As for connection, you don't HAVE to register a hotspot account but it will help if you need to get online a lot and there are no free spots near you (which will happen soon IMHO).

Hope this helps.

Centrino itself is supposed to be an Intel Pentium Mobile with Wi-fi built in. Then as for hot-spots, currently the free ones are in STARBUCKS which is by the telco TIMEZONE. Other like Airzed and TMNET requires you to buy a prepaid card.....

alright, thanks everyone for the answers.
looks like i must get a new centrino laptop then, but i need full protection against my laptop when using WIFI, what should i do then? I have only to install Norton Antivirus 2006 and Norton Internet security 2006?

actually u dont need to protect your notebook when u turn on wifi cause u already have WEP/WPA protection!!!!If u do need u can try Trend Micro PC-Cillin Internet Security 2006

http://www.antivirus2u.com/v1/

Does this software provides full protection? including Antivirus, Firewall, Anti-Spyware, and etc?
If so, why there are still so many individual security protection tool in the market? like Norton Antivirus, Norton Internet Security?

is like Proton they have Waja,Wira...... different consumer different market

Non-Standard Channel Bonding

Chipmaker Atheros sells a proprietary channel bonding feature called Super G[1] for manufacturers of access points and client cards. This feature can boost network speeds up to 108 Mbit/s by using channel bonding. Also range is increased to 4x the range of 802.11g and 20x the range of 802.11b. This feature may interfere with other networks and may not support all b and g client cards. In addition, packet bursting techniques are also available in some chipsets and products which will also considerably increase speeds. This feature may not be compatible with other equipment. Broadcom, another chipmaker, developed a competing proprietary frame bursting feature called "125 High Speed Mode" [2] or Linksys "SpeedBooster", in response to criticism of Super G's interference potential.

The problem with Super G , is that if the router does not support it (or Access Point) , its useless

I suggest you to go with the normal G. Unless you have SUper G APs or Routers , then go with that

oo..tq all, i got the picture now.

one more, super g still can't be used for hotspot area, but if i do wireless home-networking..with the correct hardware, i can get maximum bandwith rite?
