100M : VMNG300 92Mbit limit

[Skie]

I dont think configs are really modem specific. When I went to 50 meg, they sent the config a few hours before the engineer arrived with a VMNG300 and my old modem had a whale of a time trying to deal with it.

I think their made up "only 92meg" test statement is just a bit of posterior covering.

your missing hte point if there wnting it as standard kit just upgrade evryone by senidng everyone one and make it standard and dnt use old stuff anymore

imagine turning up for work Monday and having to register 2 million macs

It is a good idea (not the shub though) and what they should do is send them out to everyone but record the macs first and add them to the account before dispatch so they are good to go and then set a script to delete the old macs after a month.

If I was the head honcho for VM I would get Ambit to make a new VMNG300 with 8 channels and send one out to every customer and then you know everyone is sorted with a decent modem. If peeps want a router, setup a contract with Linksys for the E3200 and send them out to customers that request them and then you have standardised the CPE across the network with kick ass equipment which you know you arent going to have any problems with.

You don't write a config file for a modem, you write one config file, it works with all modems.

(P.S. VM also claim the Superhub can do 400mb, which it probably can't)

We have modems that should be capable of the uplifted uploads that have to be replaced with newer equipment so the is something not quite right there with the configs.

[General Maximus]

are you sure it's not the configs and the fact that the older modems physcially can't handle the speed. When I was on 10mbit donkeys years ago on docsis 1 I was upgraded to 20mbit still on docsis 1 with the new config files pushed down to the modem but it will wouldn't go above 12mbit though. I had to ring up for an Ambit 256 and then it blasted away quite nicely.

Some do work and some do not even the same model and I think you can still buy the Motorola SB5100 series new so no idea.

Its all down to the local network I'd guess. Only the VMNG300 and Superhub are DOCSIS3 devices, so they tend to be able to manage unfavourable conditions better thanks to multiple downstreams.

A DOCSIS 1/2 modem in a good area might be able to use its single channel to get 30 meg (theoretical max is 38). But on an even slightly congested network that will be unlikely to happen. A D3 modem on the other hand only needs 7.5meg from each channel to achieve 30meg, 3.75meg if you have 8 channels.

VM tech told me that the wnr300 can do 400meg.

unlikely i think the masimum each channel on docsis 3 is 55mb? if so it can only do max of 220mb but in pratic ei think it iwll onyl really do up to 150-180mb

that is correct, although I would hope it would be more around 190 ish

[Sephiroth]

If they were able to increase the QAM from 256 to 1024 then each channel could handle 69 Mbps. Igni points out that the infrastructure must be capable of handling the higher SNR required for 1024QAM to operate reliably.

There is a useful paper here. Please note that it refers to DOCSIS not EURODOCSIS; so the throughput quoted can be increased to 8/6 of the value quoted in the paper.

Also, what the hell is a WNR300?

That's a WNR2000.
