hello,

I have a English version of the TR1/B. My wireless network card is listed as: Sony 802.11a/b Wireless Network Module,

The driver version is 2.1.2.4140, dated 14/04/2003.

Is there an updated version? I keep seeing talk of extra options (such as power options) in the advanced config of the adapter mentioned in newsgroup posts but mine does not have this…

Is there an updated driver anywhere? has anybody with a TR1/B tried newer drivers?

any help appreciated.

regards,

mick.

The TR1/B is a Japanese model and that model does not use the Intel Pro 2100 wireless chipset (which makes up the Centrino brand). I’m not sure exactly what brand of wifi chipset they are using but it’s a combination 802.11a/b chipset. You may want to check with the place you purchased the “English” version of the TR1/B and see if they have an updated driver or can help you find one.

If they can’t help you can check the Japanese support site for the TR1/B which has an updated driver.

The main site can be found at: http://vcl.vaio.sony.co.jp/support/note/pcg-tr1b.html#download

and the latest driver (2.1.2.6230) can be found at: http://vcl.vaio.sony.co.jp/download/PK-000306-00.html

Please note that the driver and it’s associated control panel properties will vary from the Intel Pro 2100 drivers so you may not have any control over power usage and extra options.

[quote author=“Visotor”]According to Sony Japanese site, TR1/B uses Intel 855GM chipset.
Hope this helps.

The Intel 855GM chipset is not the wireless chipset. Instead, it’s the northbridge which contains the graphics and memory controllers. It then connects to the ICH4-M southbridge which contains the LAN, ATA, Audio, and PCI bus subsystems. The wireless solution is connected to the PCI bus via Intel’s own ProWireless 2100 solution (which is known as Centrino branding when coupled with a Pentium M and the integrated graphics) or a third party solution from another company like Broadcom, Intersil or Atheros. Intel doesn’t currently offer a 802.11a (very soon) or a 802.11g (next year) solution so it’s a third party chipset being used.

Sony doesn’t typically reveal the name of third party chipsets in their specifications for whatever reason. So, you’ll need lower level utilities to find out what chipset is actually being used. A utility like SiSoftware’s Sandra can often help to determine the chipset. I found that Sony’s 802.11g PC Card is actually driven by Atheros.

thanks for the info - I have downloaded the driver listed on the Japanese site and iwll try that next time I’m in a wireless area.

I will let you know how I get on.

thanks again,

mick.
