DSL-G604T low downstream speed

Post by Damo » Tue Dec 06, 2011 5:25 pm

I have this router flashed with the latest Routertech custom firmware. I've noticed that the downstream speed syncs no higher than 12mb, whereas the Sky Sagemcom router syncs at 14.5mb. The upstream speed syncs at the same speed on both routers, 1.15mb.

Does anyone know what the problem may be?

Is the modulation mode the same?, I believe 12Mb is the maximum for ADSL2, higher needs ADSL2_plus. There may be some tweaks (see the RouterStatsLogger) - but compare actual download speeds and stability - it may not be worth getting a slightly higher connect speed if its not as robust.

I've tried both ADSL2_plus and Multi_Mode and see no changes whatsoever.

I've tried altering the SNR via the RouterStatsLogger, but see no changes to my synced speeds either.

What download speeds are you actually getting on both routers?

I can download at a speed of 1.4mb on the Sky router and 1mb on the G604T.

Post the system diagnostics ("Tools" menu). That will show whether there is any software or configuration issue. Post also any relevant information from the Sky router (e.g., modulation, path mode, etc).

It may well be that the difference is due to the hardware. After all, the g604t is very old.
