View Full Version : AirPort extr. speed problem

Hi there,
Iīve got a question about AirPort Extreme. When connected to a Base Station via 802.11b protocol the file transfer speed from a local server is about 1.2 MByte/sec , thatīs ok. Using 802.11g protocol the transfer rate is only 2.4 MByte/sec and thatīs too slow, I guess. Iīve tried anything possible but without success. The distance between PowerBook and Base Station was only a few inch. Other possible sources of interference were shut down. Any ideas??
Thanks,
-Andreas

You need an Airport extreme base station & card to get the speed from it. the 802.11b transfers at 11Mb/ps and 802.11g is 54Mb/ps i think that works out to about 1.1MB/ps for 802.11b and 5.4MB/ps for 802.11g. So those speeds are just about normal

Maybe Iīm a little bit stupid :rolleyes: but itīs of course an Airport extreme Base Station and card I was talking about. But I guess Iīm a dreamer, believing in marketing blabla. Just read in a pc mag, that those poor transfer rates are usual in this too new 802.11g protocol.

how close are you to the basestation, this matters because the extra distance is rated over only 50 feet from the basestation.
My mistake i see that you already typed that, thanks timbloom

He said just a few inches

A .11b base station can only transmit 11 megabits which equals 1.375 megabytes per second. If you had both a .11g card and base station, the speed would be 54 megabits, which is 6.75 megbytes per second. With that said....
I don't know if this is actual real-life measurements. Other things to take into account is the speed at which the computer you are transfering files from is sending the data, or reading it from the drive. Are you transfering from one wireless machine through the base station to the other?
What are you doing to test the speed?

The mac I am transfering data from is connected directly to the LAN port of the base station. Itīs a G4 with fast Ethernet port. For speed testing I used a little utility called Granet and simply count what time it takes to copy a 1 GB file. But as I wrote before, I donīt believe that transfer rates above 2.5 MByte/sec are currently possible. Maybe several firmware updates later...:rolleyes:

sadly, this is the results you get when adopting immature technology.

I"m glad apple is the first one in the pool with this technology. If you think back everyhing was once new and apple integrated it seemlesssly. I assume that soem ofthe problems appple could be having might be resolved with future firmware updates like always.

You can only transfer as fast as your slowest chipset. Just because "g" is capable of going that fast, doesn't mean your hardware is... It is all marketing... Ask a wireless network specialist you will NEVER EVEN COME CLOSE to 54mbs even if your computer is sitting right next to the base station.
Sorry to rain on your parade :D
Oh sorry... hard drive speed comes in to play strongly as well
