[cisco-nas] IOS, SPE & modemcap Recommendation

[Darryl Sladden (dsladden)]

Chip,

These are complex problems and I would recommend 
getting support on the AS5350 and opening a TAC case.

The SPEWare can be upgraded independently of the 
IOS.  The lastest SPEWare optimized for dialup is 8.XX.

You can definitely play with the modemcap, but it 
will only be helpful in a definate problem is understood.

"Having trouble staying connected" could mean lots of 
things include dirty lines and faultly client modems
that upgrading the NAS will not help with.

Good luck.
