Well here is my experience in this -- I have a DELL 8100 Dimension purchased in Jan 2001....it has a
v.90 modem.....I am running Win XP Home.......I frequently get dialup speeds of 48 kbps.. no problem but occasionally get 44 or at the very least 33 on occasion........ i dont think problem is your modem ......a probablity to look into is your local telephone lines..........certain lines can cause a slower kbps if is a low quality phone line!
Ask your telephone company to check this out to verify what your maximum modem runs speed it can support. One thing they will tell you is that phone lines only guaranty good audio quality but not computer modem performance.........so you could be stuck if this is the case with poor phone line quality. my understanding of the modem v.90 vs v.92 is that the dialup connection on the v.92 is fater than v.90 but if both are rated at 56K..there should be no difference in modem speed overal. hope this helps...
V.92 includes an upload Speed enhancement only (up to 44K), and Download speed is identical to V.90. V.90 only addressed download enhancement for web browsing but upload speeds were stuck at 33.6 or 28.8 (or worse).
If you are getting only 28.8 or 33.6, then two things are suspect.
1) This usually a CO problem. It can be caused by distance to CO or old CO technology. To achieve V.90 speeds only 1 conversion from Digital to Analog can occur (download direction) or you cannot achieve faster speeds than 33.6. This is why you cannot call modem to modem on a V.90 and expect anything higher than 33.6. You will use V.34 for this type of connection since there are two conversions A/D and then D/A.
2) Premise wiring may be old or too many daisy chains causing poor line balance (this is usually not the problem).
A call to your PSTN provider (Phone Company) can go a long way. Tell them you are not negotiating at V.90 speeds. I had experience where the phone company changed my line card at the CO (based on my complaints) and it increased my speed from 44K to 53.3K (Maximum allowed by FCC).
