知り合いのテック・ガイからのアドバイスを貼り付けておきます。私は全くロウ・テックな人間なので分かりませんが。お役に立てればうれしいです。
Hello. I do not speak/read Japanese, but a friend who does has asked that I help with this. I do not have this D-Link card nor at the moment a PC (mine has a dead PC slot, so I’m on a Pocket PC), but this advice taken from a discussion thread found through Google seems relevant.
http://www.driverforum.com/network5/10437.html
I have in the past used the DriverGuide service mentioned by the last poster in that thread, and have always found the files to be useful if I check carefully for the correct one and then follow safe computing practices.
Because one must be a DriverGuide member to download, and this is rather an annoying procedure, I took a couple of minutes to seek and find the XP file and upload it to my server space for you. I’ll leave it up for a few days, for you to get a copy. It’s here:
http://www.luthier.ca/other/Ndis.vxd
Using the Find | Files and Folders tool in the Start Menu, seek for an Ndis.vxd file in your Win98 PC. When you find the location, navigate there in Explorer. Re-name the file to Ndis.vxd-old or any other name you like, and leave it there in case this does not work and you need later to re-name it to the original name. Then move the file you downloaded from my link to the same folder. Reboot, and if the other forum poster is correct in his advice you might have a better result.
I cannot over-emphasize the importance of safety whenever dealing with network or system drivers generally. BACKUP anything important first. Perhaps you already do, but this is standard advice, as also offered on DriverGuide. I cannot know for certain that this file is safe, I only know that it is offered in good faith and that it might be a solution. Good luck to you.
Further, I have found success in the past using a Microsoft PC Wi-Fi card... an MN-520 I think it was, and also with a SparkLAN CF card, a WL-672 in a CF>PC adapter. Drivers were a bit of a search in both cases, and this was with ’98SE, not 98. But both work fine, provided I used the GemTek (they wrote various versions for SparkLAN and others) drivers released about 2 years ago. Further information is available here and there if you search, or contact me. Win98 can be a pain for wireless, but it can work.
