I've had the same problem with these new e-modems... bought two and neither could hold a connection up for more than 2 minutes on a line that was anything less than perfect.
They seem ok on a good line, but HSF PCI modems seems to be more reliable if the line is slightly 'rural'... which is saying something. They have totally put me off dynalink... I sell D-Link externals to my customers now... about $20 dearer, but much more stable. Steve > Hi all, > > I recenly upgraded to a blazingly fast 56k modem. Dynalink 1456VQE-C; > the "e-modem".
