| 196510 | 2003-12-05 06:52:00 | The reported speed of 115200 is a red herring. That is NOT the modem connect speed, its simply the speed at which the PC serial port talks to the modem. Its the standard RS232 port speed, and has no relevance to the actual modem connect speed. Why it alternates between the two reported parameters is not clear, however even when it reports 115200 it could well still be connecting at 28000 or so. Have you tried Windows default generic external 56k drivers? There is little needed for a hardware modem in the way of drivers at all, as the modem has its own CPU and ROM based program. If the modem is recognised by the ISP, and the line allows it, maximum speeds should result. The PC can limit the speed with strings, but in the absence of them the hardware modem should connect correctly. And my involvement with modems was primarily at 50 bps, then 300 bps as things got "faster" |

| 196512 | 2003-12-11 07:13:00 | Understood that it is not the speed that the modem is talking to the distant computer at, but the 28000bps still constitutes a 'bottleneck' which is randomly appearing in my system and I do not like it. Especially since when it is all correct the speed of browsing is quite definitely better than the Genius modem. For instance I have no trouble getting into Press F1 anymore which was a problem before although the FAQ's are still a problem. What gives with the FAQ's, why are they so hard to get into? Anyway here is the reply I got from Clear.: From : ClearNET Help <help@clear.net.nz> Sent : Thursday, 11 December 2003 2:35:54 p.m. To : 'Robert Worrill' Subject : RE: New Dial Up Modem Problems. Hi Robert, We don't currently support the v.92 standard. There may be a few modem banks which support V.92, but these are mainly for testing purposes. There is no way to ensure a connection to our V.92 modems everytime. Along with ISP support, V.92 also requires your local telephone exchange to provide support for its new features, and I believe very few of these support V.92. Consequently your modem will be negotiating a V.90 connection to Clear.net. Your connection speed is largely dictated by the quality of the phone line you are connecting over. Any connection above 56000bps is being reported incorrectly - this will likely be a bug in the driver software of the modem if it is only occuring sometimes. If it is happening on every connection, then you may have the wrong driver installed for your modem. Further to this, connection speeds can only be used as a rule of thumb. If you were to compare two different brands on v.92 modems, you will probably find they will report different connection speeds. Alot of modem manufacturers will force the modem to connect very aggressively so it appears that their brand of modem is better than another brand. You will likely see the exact same download speeds on the same phone line though. A good connection speed is considered to be anything from 46000bps-56000. 56000 would require perfect line conditions which is unrealistic. -- Regards, Andrew Redgwell TelstraClear Ltd. So there you are. Thanks for the time and effort. I am still working on the problem and Win98Se sys is now 100%, Win2000 is getting that way, mostly connecting first time at >56000, whatever that means when it does connect at 28000 or less it is noticably slower. Regards Robert. |
