We do our best to provide fast and courteous technical support. Hope it helps with any questions you may have. We have investigated the problem and have come up with a few ideas that should help identify the problem. We have also found that the v-90k56flex hsp pnp modem works well.
Performance is poor if they connect at all.
If you don't know if your modem is compatable, call the manufacturer or upgrade your modem to one of those listed above. If you have one of the ones listed as good performers and still have problems, then it could be a phone line problem or a modem issue. Make sure the correct V-90 driver is loaded, and if it is, that it has been done properly. Hopefully, but not to be ruled out, you may have a defective modem. All these things need to be addressed.
