I am haveing great difficulty in finding software for Sumvision(W322P) 300M 802.11N Wireless PCI Adapter.. the manufacturers website has bad links (reported) and although it seems to be a Ralink device ,they have drivers for "similar" units but not a functioning driver ! So,if anyone has the original software cd and will send drivers or link that will work it would be great ..Wndows XP SP3..old HP workstion ...I had this card functioning great for 2 years and now reformatted drive and reinstalled xp and cannot find disk ! Bugger !! thanks in anticipation

Short, practical plan to get that Sumvision W322P working again (and avoid unsafe downloads). As discovered, vendor pages and random file‑host zips are unreliable; first identify the actual chipset on the card, then get the matching driver from the chipset maker or a reputable vendor site rather than an anonymous ZIP. (manua.ls)

Follow these steps (in Windows XP):

  • Open Device Manager, find the unknown network device, Properties → Details → Hardware Ids and copy the top value (it looks like PCI\VEN_xxxx&DEV_yyyy).
  • Use a PCI/Vendor ID lookup (or a small utility like PCI‑Z) to translate VEN/DEV into the chipset/vendor name.
  • Search for a driver that explicitly lists that chipset or that exact hardware ID; prefer the NIC vendor or MediaTek/Ralink archives if the chipset is Ralink.
  • Install via Device Manager (Update Driver → browse to the extracted driver files) or use the vendor's installer after creating a system restore point. (learn.microsoft.com)

If the hardware shows a Ralink/MediaTek chipset, try official Ralink/MediaTek driver packs or well‑known archives that host the older RT2860/RT309x families — Ralink is now part of MediaTek so many legacy drivers live under that umbrella. Avoid unverified file‑share zips; manufacturer or Microsoft‑recommended sources reduce malware risk. (en.wikipedia.org)

If a matching driver still won’t install, open the card and read the large IC marking (users have reported finding RT3xxx markings on W322P cards), or try a cheap modern USB Wi‑Fi stick as a pragmatic replacement — Windows XP support ended April 8, 2014, so using XP online has security risks. (learn.microsoft.com)

These steps usually turn a confusing “which driver?” problem into a clear chipset → driver match, and avoid the hazards of random downloads.
