Hey guys,

I have a wierd problem! Up until a little while ago, I had a Puretek PT-3812 honking piece of crap adsl modem. It was going fine until it went kaput. I have a Linksys ADSL2MUE as a backup, which I used while I find a new modem.

Upon the recommendation of a good friend, as well as general googling, I decided upon the Dynalink RTA1025W (http://www.dynalink.com.au/modemsadsl_cur.htm?prod=RTA1025W). The modem works fine, will everything seemingly okay, apart from the speed.

The RTA1025W, on average, connects at about 1800-1900 Kbps. In comparison, my now dead Puretek connected at about 3800 Kbps. The stopgap Linksys connects at 5000 Kbps average, sometimes hitting 6000 Kbps, before and after connecting the Dynalink.

I know that these are line speeds and not necessarily download speeds, however they are proportional. On the Dynalink, I get a max download speed of 200 KBps from Citylink. On the Puretek, I used to get a maximum of 320 KBps, and on the Linksys I get 400+ KBps.

I have taken the modem to a mate's place, which is in a different suburb about 20 km away, and it connects at 4800 Kbps.

I have no idea what's going on, which is why I've posted here, to give you wise heads a challenge!

Any help would be much appreciated,
Vipul

I've used this range of Dynalink modems for quite some time, and generally they are a good unit. They pack quite a few features (e.g. QoS) etc, for their price point. They also tend to be quite a stable unit, particulaly on a marginal line, where other units may have more frequent disconnect issues. The downside to these units is that there is a trade of in performance, so I guess it depends whether you want fast n fickle, or slow n steady.

However, looking at the info you have provided, it would seem there may be other issues causing this big gap in speed between routers. You should try some isolation tests, i.e. unplug every other phone/fax etc device (including filters) in your home, so you are just left with the router. Power cycle, and see what the produces. If this makes a big difference, then start a bit of trial and error to see if there is a particular phone or something that is causing it. If that doesn't work, contact your ISP & get them to line test etc. You may also want to consider upgrading to a full install.

I haven't tried unplugging everything and then trying the router, I shall do that when I get home.

I actually forgot to mention in my post that I already have a full install.

Thanks for the reply,
Vipul

Ok so I just unplugged everything I could (unfortunately the alarm connection was no-where to be found) and the speed is still at about 2000 Kbps.

I've also gone into the settings and changed it according to this: http://jetstream.xtra.co.nz/chm/0,8763,204585-203775,00.html . I have also disabled everything but G.DMT and TI.413 as per that page.

I haven't had a chance to ring my ISP yet, I will do next and see what they say.

Thanks,
Vipul
