i was talking to my ISP about upgrading to ADSL2 modem, I said i had a apple airport (wifi router) already but he was saying i needed a WIFI modem not a single ADSL modem as the single modem does not have "the power" to have multiple users run we off the Airport...
this makes no sense to me al all ..... and i was made to look stupid for questioning this, not that i am any clearer why?

so i get a single user ADSL2 modem and run computer via ethernet i get 100% of whet ever ADSL speed

or i get ADSL2 modem ethernet to my WIFI router used by two users we get 50% of speed each

or i get ADSL@ WIFI router i get more then 100% of single modem ? i think not

can anyone make understand what he was trying to explain re the POWER ?

thanks

I am not even sure ADSL2 modem will make a difference to my speed or be worth the investment...

Hi, the guy you were talking to is talking BS. A single port ADSL2+ modem/router can serve quite a number of PCs, however as there is only one ethernet port you are limited to the number of wired PCs that can be connected at anytime, obviously a simple switch to expand out the number of ethernet lan ports will fix this.

If you were to connect your WiFi router to the lan port of a single port modem then you can serve multiple PCs wirelessly, the speed each will get will be naturally shared and the actual throughput speed will be shared depend on what traffic each PC is demanding at anytime, this will be the same for a modem with builtin WiFi or in the situation you describe.

Personally I would avoid taking a ISP provided modem, you can get very good and cost effective 4port ADSL2+ modems like the DSE XH9949 for only $70, add your airport and you have both wireless and wired ability. To see if you are in a ADSL2+ area go to Telecoms map site to check

Thanks cyrill7 I thought the telecom sales person was talking BS.....

Re the DSE XH9949 i have had problems in the past with ichat / video chat and (DMZ i think or something like that ) i managed to get it to work ok now... will the DSE modem let me do what i need with out to many problems ? I think now my Airport does all the firewall stuff and the modem does stuff all beside connect ? doe that mane sense... damn i cant get my head around this stuff.

+1 to Cyrils comments.

"Single PC" modem is just a "Single port" modem. Add more ports by way of a switch, or a wireless AP / router, and you are totally sweet as. VERY common thing to do.

Rep needs to go work the production line at Mickey Dees.

To be fair, most single port "routers" won't have the memory or cpu capabilities of their 4 port/wireless brethren, this doesn't mean that a single port router and a switch won't do you well, but does mean that UPnP, large NAT tables and hundreds of TCP/UDP streams will bring your network to it's knees. I doubt that the sales person's knowledge quite extended that far even though they were kind of correct.

I'd strongly recommend a Dynalink 1025W or a Linksys/Draytek of some sort. While some of the cheaper models will have the features you're after, the more expensive units will do the same features better. You get what you pay for :)
