Lucent V90 or V92?
Hello Folks, I bought an 8200 in December 2001. The Dell packing slip lists the modem as "Item # 313-0717 V.90/56K Telephone Modem for Windows Part # 76EPH. Windows XP identifies it as a Lucent modem. The Dell supplied software reinstall CD lists it as a V.92. The Dell "System Shipped As New" lists a V.92 modem. Any way to ascertain which it is short of opening the case? I have been having problems with connection speeds, and after using 3 different ISPs over the years, I seldom get a download speed of greater than 28.8K, sometimes I get 33.4K. (Using the modem speed tests available on CNET and another website.) I installed the Dell "Modem Helper" from the CD, and ran the diagnostics. It recommended I reinstall the software. Can anyone comment on how reliable this utility is? I fully realize that 56K is smoke and mirrors, but I would like to do better than an average of 30K. My phone jack is less than 6' from the PC, and I ran a new cable just to be sure. There is no audible "line noise", although I have yet to run the tests outlined in Dell document # HO1042823. Thanks in advance to all who reply. ( PS-- My Win XP "maximum port speed" is set to the maximum, 115,200. Disabling Win XP's firewall, as well as Norton AV and Personal Firewall also makes no difference.) Josterberg

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).
