Just look for Realtek 8139 drivers.

If you refer to my "Tenda TEL8139D" card, none of Realtek 8139 drivers have worked so far, on Win 3.11.

After googling a bit, it seems the win95 driver is a ndis3 driver. (at least the one in 9939DI12.zip)
It might just work on windows for workgroups, provided you install it manually or bake an oemsetup.inf file.

The last version of the OEM disk set I could find is v5.00 and it covers "RTL8139C(L)+/RTL8139D(L)/RTL8100(L)" and covers DOS thru XP (does have WFW3.11, DOS and Packet drivers).
There are no drivers for a RTL8169 series prior to Win9x that I could find (and is what I expected for most 10/100/1000 NIC's).
Will post the 8139 file to Vogons Library after checking around a bit more ....
added: the 8139 driver in the library is v3.90 which appears to not cover the 8139D variant, only thru variant C ....afaict

Thanks Azami, I'll give it a try but unlikely to work (tried similar ones earlier)

Hi Horun, thanks so much for your detailed reply. Yes indeed I tried the current one in the Vogons Library, didn't work. So the one you have it there, have you managed to uploaded it? I'd love to try it.

Thanks once again.

Which PCI ID does your RTL8139D provide?

If it does not work then am not sure what to do to help as that is the last DOS/WFW driver set I could find for 8139 series that specifically mentions the 8139D.
Here is the archive link from 2011 that got me info to help find the file (all older Realtek were on FTP):

I suggest running the Rset8139.exe and see if it actually see's the NIC, if not could be a compatabilty issue with your board or it's BIOS on the DOS level, as the Win3.x drivers require a DOS based *.com as am sure you know.

Thank you very much Horun (and all) for all your great help and information!

The driver you posted didn't work, I've also ran "Rset8139.exe", it reported no LAN card installed. So I gave up and bought a compatible NIC with my system.

Thanks anyway, much appreciated!

Too bad. I did find some drivers for the 8169 for DOS NDIS2 (Lanman, MSclient, etc) and Netware DOS ODI at an archive of www.network-drivers and also here:
https://www.helpdrivers.com/networks/Realtek/RTL8169SC_L/
My guess is that they will not work under WFW either since the 8169 is an advanced 8139....

I have to say the card doesn't support Win 3.11. I bought this card back in 2003. Here is the original driver floppy and the readme file included in the disk. If anyone needs the content, I'll upload it.

BTW, the card has nothing to do with Realtek RTL8139D, it's actually a Sundance ST201. WinXP will automatically recognize it as this name.
