| 406757 | 2005-11-23 05:22:00 | A good friend who is a stewardess and travels all over the US in her work has a problem with a WIFI hookup at hot spots around the states. Since I do not use WIFI and have little input, can someone enlighten me as to the probability of her statement in an E-mail question to me as follows: I had a man at the airport look at my PC card while i put it in the puter at the hot spot in the airport and he said it is because it is only an 11mbps and should be 55 mbps and that's why it's not working. is that true? I really don't know how to answer, and not wanting to mislead her, can someone here enlighten me? :stare: |

| 406758 | 2005-11-23 05:26:00 | It might be coz 54mbps which is 802.11g (which as u can see is faster than the PC card, your friend is using). And 802.11b which by the sounds of it, is what she's using (11 mbps). And the airport may only support g (54mbps). Which is why it doesnt work. She needs to get a PC card which supports 802.11g, which runs at 54 mbps. |

| 406759 | 2005-11-23 05:27:00 | It may be correct, but depends on the context. There are 3 WiFi protocols currently certified, 802.11a, b and g. G (54Mbps) is backwards compatible with B (11MBps), however if her laptop is A (11Mbps), then it won't be able to connect to a B or G network. That could be the problem she has. How old is her laptop and her WiFi adaptor? |

How old is her laptop and her WiFi adaptor? Actually .a is 54mbit technology, the difference between .a and .b/.g is that they use different bands - b/g use 2.4GHz, sharing that slice of spectrum with bluetooth, cordless phones, microwave ovens and many other ISM band devices. .a on the other hand uses 5.xGHz, hence the incompatibility. While .g access points are backwards compatible with .b devices, many .g access points have a "g protection" mode that lets only .g devices connect, and many AP admins tend to favour this mode as SOHO AP's tend to drop back to the speed of the slowest device - if a .b card hooks up, everyone gets dropped back to .b speeds. (You will usually still get more throughput than if you were on a plain .b AP, but I digress) .b devices also do not have some of the security features of .g, so if the AP's are setup with WPA/WPA2 etc, then the .b device may not be able to connect. |
