Try 3Com's website. If you can't find drivers for Windows 7, try those made for Vista. Windows 7 is designed to run hardware with Vista drivers.

I found this useful solution, it might help some one here.



In the afternoon (7 hrs ago) I installed my first Vista Business
OEM-version. I was surprized that Vista did not find any suitable
for my 3COM 3C905-TX network adapter. Even if this is not a
brand new network adapter model it was some years back the most popular
of the 3COM 10/100 adapters.

Time to start Googling to get this sluggishly slow Vista up and
networked. Uhh, this Vista is a real crawler, even on an Athlon 3500 CPU
with 1 GB of RAM.

I soon found serveral others looking 3COM Vista drivers also. Someone
told that 3C905 drivers are there on the Vista installation-DVD, and
they should get automatically installed. I tried this and made Vista
search drivers again from the DVD, but again it did not find anything.
Some other suggested that Driver Guide site has new and suitable Vista
driver for 3C905. I again found nothing Vista related from there.

The solution for this Vista problem simple once you find it. Just go and
download this 5 year old driver from 3COM site here:

"3c90x1.exe" "07 Nov 2002" "Size: 0.89 MB"

Run the EXE that appears to be a DOS-style self extracting file and
extract it to some temporary folder. Now make Vista to look 3C905 driver
from that folder, and Vista finds a driver and installs it. After that
you can go and check the driver version and it looks like this:
"File version: 4.31.0000 Copyright 1994-2002, 3Com Corporation."

Vista is now completely happy with this driver and you can get to the

But once you now got to the web you can make Vista to look even newer
driver, it even seems to find something and installs this kind of driver
"File version: 4.41.0000 Copyright 1994-2002, 3Com Corporation."

There is only very small, or none, difference between those driver
versions and both seem to run fine on Vista.

So this was only for 3C905 adapter, now there is only 10.000 other open
Vista driver problems to be solved. Hopefully someone could save 7 hours
of his/hers work time with this tip

For anyone looking to use this in a machine, to get the driver from 3com is no longer possible, as HP has taken over. They don't list this model any longer.

I was able to search "3c90x1.exe" (without quotes) and of all places had this available for download! Yay!!
