Sir, My ZTE ZXDSL831 USB Modem driver is not recognized by Windows XP 64 bit operating system. However the net is connecting with LAN but it disconnects within 2 minute. Driver CD came with this modem contain only 32bit DLL file named GsiDi32.dll, but in the INF file, there is information about "64 bit class installer" with GsiDi64.dll written too. Can I install it on 64 bit of win xp with INF only and without 64bit DLL. Please help !!! 1 person needs an answerI do too
